Microsoft Sentinel Reviews

I support Microsoft Sentinel as a Microsoft partner. We work on various scenarios, such as emails and data connectors. I support licenses by helping them enroll and advising them on the prerequisites they need to meet. I show them how to get started with Microsoft Sentinel. 

I'm the technical lead for Microsoft, so I've worked on several Microsoft security products, including Sentinel, Cloud App Security, Defender, Azure Information Protection, and Azure Key Vault. These are now my significant areas. It wasn't easy to integrate Sentinel with other products initially, but we had a smooth experience once the data connectors and everything were in place.

We are from the support team, so we operate in multiple environments depending on the use case. It works smoothly in every environment, including hybrid ones.

I've seen scenarios where the customer's security score was at 60, but we managed to increase it to 80 or 90 based on the recommendations from Sentinel. We use Sentinel to investigate the activity logs and address the issues. The security score increases once we fix those. 

The benefit Sentinel provides depends on the organization and how they have recruited engineering staff. If the engineers can maintain two or three products, then it's easy for them, but it hasn't reduced any difficulty from my perspective. 

Sentinel saved us time. When this product was introduced, many customers used other SIEM and SOAR technologies separately. Now that we have Sentinel in place, customers only need to learn how to use this product, so it's 50% to 60% more efficient. It's also more cost-effective because you aren't paying separately for those security components. Sentinel is all-inclusive. 

Sentinel integrates seamlessly with Azure platform services, making it more reliable and cost-effective. I can't say with certainty because it's outside my department, but my best guess is that Sentinel can reduce costs by about 30% to 40%. I would also estimate that it reduces our response time by roughly that amount. 

The bidirectional sync capabilities ingest the data and show us alerts that help us prioritize our policy settings and secure our environment. Once we ingest the IP address, we can monitor the network traffic. It ingests everything from the IP address to the applications we use at the cloud level. Having every event, alert, and output from Log Analytics integrated into one platform is essential. We can ingest everything using the syslogs and data connectors. For example, I'm using Windows Server 2016. It will send the data to the cloud, and Microsoft Sentinel pulls it from there. It removes the sysadmin logs and the other logs, so we can easily see the DDoS attacks and other threats.

It ingests the networking stuff and other things, too. It collects everything the company needs to secure the data from data engineers, Log Analytics engineers, information production engineers, etc. It ingests data from everywhere and stores it in one place. You can pull whatever data you need. 

A security product must be integrated with multiple other technologies like SIEM and SOAR to give you the best results and analyze user behavior. Sentinel uses connectors to integrate all Azure products and third-party security tools.

Sentinel provides excellent threat visibility, enabling us to dig deep. It directly connects to Azure Log Analytics, allowing us to do research and pull logs. It uses SOAR intelligence to detect and fix issues using AI and machine learning algorithms.

The ability of all these solutions to work together natively is essential. We have an Azure subscription, including Log Analytics. This feature automatically acts as one of the security baselines and detects recommendations because it also integrates with Defender. We can pull the sysadmin logs from Azure. It's all seamless and native. 

Everything shares a common database so that every product can be integrated depending on your enterprise licenses. Microsoft is effortless from a customer's perspective. You get a wide range of features with one license, including threat detection, information protection, infrastructure solutions, and endpoint protection. One or two enterprise licenses cover everything. 

Sentinel is an excellent product with multiple dashboards if you want to look at something specific. It also has a centralized dashboard for everything if you want to see the overview of what's essential. I use multiple dashboards because it's easier for us as support team members. 

Microsoft Defender has a built-in threat expert option that enables you to contact an expert. That feature isn't available in Sentinel because it's a huge product that integrates all the technologies. I would like Microsoft to add the threat expert option so we can contact them. There are a few other features, like threat assessment that the PG team is working on. I expect them to release this feature in the next quarter.

I have been using Microsoft Sentinel for two-and-a-half years

Sentinel is stable. 

I rate Microsoft technical nine out of 10. 

Setting up Microsoft Sentinel is straightforward because it's a cloud platform. You can install it with a few clicks. It isn't like the on-premises solutions we have used in the past, where you need to spend a couple of hours. You can deploy Sentinel with one person in around five minutes if you have all the resources, permissions, and rules.

Like all products, Sentinel requires some maintenance. There are planned and unplanned outages. Depending on when Microsoft releases the updates, it can be challenging, but they usually notify us ahead of time.

Microsoft offers the best value from a customer perspective.  With a small amount of money, customers can take advantage of an array of technologies because everything is connected from the Microsoft perspective. The return on investment is massive. You don't need to recruit multiple engineers. One engineer who is familiar with Microsoft products can manage the solution. 

I think Sentinel's pricing is reasonable. It's more reliable if it can integrate with other enterprise technologies, so you have to pay for that. We have to consider the size of the organization. We might shift to other security products for a smaller company. Given the reliability of Microsoft support, Sentinel is cost-effective.  

Sentinel is one of the best products compared to other SIEM solutions like CyberArk. Microsoft's market share is enormous, and they have surpassed AWS, so more companies are adopting Sentinel. A company can centralize everything with Sentinel, and that's great from a cost perspective. 

I rate Microsoft Sentinel nine out of 10. I see a few areas of improvement, but they are already working on implementing these features. If someone asked me whether I would recommend an a la carte approach using the best-in-breed solutions or an all-in-one integrated package from a single vendor, I would say that both approaches have advantages. However, I think it's good to hand everything over to the vendor. A vendor will take the sole responsibility and do the work for you. 

I also recommend becoming an expert in Microsoft Sentinel because it has a bright future. You can earn a decent salary once you have hands-on experience with this product. Sentinel is not well known, but I think it will have 60 to 70 percent of the market share.

We're a managed security service provider using Sentinel for its primary SIEM capability. Our company looks after multiple Sentinel instances for a variety of customers. However, we don't do anything through Lighthouse because every customer we monitor wants everything in their own tenant space. 

The company ensures suitable detections are created and loaded into the Sentinel side, and we provide them with KQL to help them with some in-house use cases with a security focus. We also made some dashboards so they could visualize their data and what their issues would look like. We adopt different deployment models depending on the customer. It's usually a public cloud or hybrid in some instances.

We work with a few Microsoft products, but it's mostly the Defender for Cloud Suite, including Defender for Endpoint and Defender for Cloud. It's undergone a rebrand from the Cloud Application Security side. We also use Azure Active Directory, Microsoft Cloud Security, and several other Azure and Office 365 applications.

Sentinel made it easier to put everything into one place instead of checking multiple tools, especially when working with Microsoft shops. They focus a lot of the efforts on the Sentinel side, so the data is being correctly pushed across and easily integrated with third-party capabilities. Palo Alto and Cisco feeds can work almost side by side with the native Microsoft feeds seamlessly.

Sentinel helps us automate routine tasks and findings of high-value alerts from a detection perspective. Still, I haven't made much use of the SOAR capabilities with the Logic Apps side of things because of the cost associated with them, especially at volume from an enterprise environment. It was felt that using those features might push some of the usage costs up a bit. We thought it was more of a nice-to-have than something essential for the core services we wanted to leverage. We avoided using that again, but it was more of a cost issue than anything. 

Instead of having to look at dashboards from multiple parties, we have one place to go to find all the information we want to know. This consolidation has simplified our security operations. 

Usually, it isn't good to have all your eggs in one basket. However, with Azure replicating across the data center, it's better to have all your eggs in one basket to effectively leverage the raw data that would typically be going into multiple other tools. Having everything in one place allows a nice, clear, concise view if you want to see all your network data, which you can do easily with Sentinel.

Some of the UEBA features helped us identify abnormal behaviors and challenge users to ensure it's undertaking particular activities. You can isolate accounts that may have been compromised a bit quicker.

Sentinel reduced implementation time and sped up our response. I can't give a precise figure for how much time we've saved. Onboarding an Azure feed to a third-party SIEM system might take a couple of days or weeks to get the relevant accounts, etc., in place. Onboarding is a matter of minutes with Sentinel if it's a Microsoft feed. Having everything in one place makes our response a little quicker and easier. The KQL can be easily transferred to support the threat-hunting side because all the information is just there.

Our threat visibility also improved. Sentinel changed a lot since I started using it. It's like a whole new product, especially with the tighter integrations on the Defender for Cloud. For customers heavily reliant on Microsoft and Azure, it's much cleaner and more accessible than logging in to multiple tools. 

I think some of the two-way integrations started to come through for the Defender for Cloud suite as well, so whenever you closed off notifications and threats, et cetera, that were being flagged up in Sentinel, it replicated that information further back to the source products as well, which I thought was a very nifty feature.

It helps us prioritize threats, especially with the way that the various signatures and alerts are deployed. You can flag priority values, and we leveraged Sentinel's capabilities to dynamically read values coming through from other threat vendors. We could assign similar alerts and incidents being created off the back of that. It was good at enabling that customizability.

The ability to prioritize threats is crucial because every business wants to treat threats differently. One organization might want to prioritize specific threats or signatures more than another customer based on how they've structured and layered their defense. It's useful from that perspective.

The native integration of the Microsoft Security solution has been essential because it helps reduce some false positives, especially with some of the impossible travel rules that may be configured in Microsoft 365. For some organizations, that might be benign because they use VPNs, etc.

Sentinel lets you ingest data from your entire ecosystem. When I started using it, there wasn't a third-party ingestion capability. We could get around that using Logstash. It was straightforward. The integration with the event hub side allowed us to bring in some stuff from other places and export some logs from Sentinel into Azure Data Explorer when we had legal requirements to retain logs longer. 

I've used  UEBA and the threat intel, which are about what I expect from those sorts of products, especially the threat intel. I like how the UEBA natively links to some Active Directory servers. It's excellent. Integration with the broader Microsoft infrastructure is painless if your account has the correct permissions. It was just ticking a box. It's clear from the connector screen what you need to do to integrate it.

The integration of all these solutions helped because they all feed into the same place. We can customize and monitor some of the alert data from these various products to create other derivative detections. It's like an alert for our alerts.  

For example, we could look at a particular user IP or similar entity attribute and set an alert if they've met specific conditions. If there are more than a given number of alerts from different products, we treat that as a higher priority. It's beneficial for that.

Sentinel could improve its ticketing and management. A few customers I have worked with liked to take the data created in Sentinel. You can make some basic efforts around that, but the customers wanted to push it to a third-party system so they could set up a proper ticketing management system, like ServiceNow, Jira, etc.  

It would be helpful for incident responders to be able to assign tickets and have permissions assigned to them. Once you have escalated tickets from Level 1 to Level 2, there may be areas where you want to control who has access to the raw Sentinel tool. 

I started using Sentinel in July of last year.

Sentinel's stability is great. We only had one outage for a couple of hours, but that was a global Azure issue. 

I think I've not had to worry too much about the scaling. It seems to be able to handle whatever has been thrown at it. I assume that's part of the SaaS piece that Sentinel falls under. Microsoft will worry about what's happening behind the scenes and spin up whatever resources are needed to make sure it can do what it needs to do.

I rate Microsoft support a ten out of ten. We had a few issues with certain filters working with some connectors. There were problems with certain bits of data being truncated and potentially lost. I spoke to some people from the Israeli team. They responded quickly and tried to be as helpful as they could. 

Support made a solid effort to understand the problem and resolve it. They maintained regular communications and provided reassurance that they were sorting out the problems.

Positive

I used Elasticsearch, Kibana, and Splunk. We switched to Sentinel because of the ease of use and integration. Microsoft infrastructure forms the backbone of our environment. We use Azure for hosting, Active Directory for user accounts, and Office 365 for communications and data storage. 

Sentinel made a lot of sense, especially given our difficulties getting our data onboarded into the Elasticsearch stack. We saw similar challenges with Splunk. Sentinel works natively with Microsoft, but we've still had some pain points with some of the data sources and feeds. I think that's just more about how the data has been structured, and I believe some of those issues have been rectified since they've been flagged with Microsoft support.

At the same time, Sentinel is a little more costly than Splunk and the Elasticsearch stack. However, it's easier to manage Sentinel and get it up and running. That's where a cost-benefit analysis comes in. You're paying more because it's easier to integrate with your environment than some of the other providers, but I'd say it is a little on the costly side.

I've spun up my instance of Sentinel for development purposes at home, and it was quick and easy to get through. The documentation was thorough. From the Azure portal, you click Sentinel to ensure all the prerequisites and dependencies are up and running. On the connector side, it's just a matter of onboarding the data. It's straightforward as long as you have the correct permissions in place.

Deployment requires two or three people at most. You probably don't even need that many. Two of the three were just shadowing to get experience, so they could run with their deployments.

It doesn't require much maintenance. Microsoft does a great job of building a SaaS solution. Any problems in the region where Sentinel is hosted are visible on the Azure portal. Once the initial configuration and data sources are deployed, it takes minimal upkeep.

The deployment was done in-house.

It's hard to say whether Sentinel saved us money because you only know the cost of a breach after the fact. We'll probably spend more on Sentinel than other products, but hopefully, we'll see a return by identifying and remediating threats before they've become an actual cost for our clients. 

Sentinel has made it a little easier to get the initial Level 1 analysts onboarded because they don't need to know how to use, say, Palo Alto's Panorama. They can focus their efforts on one query language that enables them to go across multiple different vendors, products, and tools. It's quicker for a Level 1 analyst to get up to speed and become useful if they don't need to learn five or six different ways to query various technologies.

Sentinel's pricing is on the higher side, but you can get a discount if you can predict your usage. You have to pay ingestion and storage fees. There are also fees for Logic Apps and particular features. It seems heavily focused on microtransactions, but they may be slightly optional. By contrast, Splunk requires no additional fee for their equivalent of Logic. You have a little more flexibility, but Sentinel's costs add up. 

I rate Sentinel an eight out of ten. My only issue is the cost. I would recommend Sentinel, but it depends on what you want to get from your investment. I've seen Sentinel deployed in everything from nonprofits to global enterprises. With multiple vendors, you're more at risk of causing analyst fatigue.

Microsoft has done a great job of integrating everything into one place. The setup and configuration of Azure's general hosting environments reduce the risk. Most services are on the cloud, so Sentinel makes it much quicker and easier to get up and running. You don't need to worry about training and getting multiple certifications to have an effective SOC.

I recommend sticking with Sentinel and putting in as many data sources as you can afford. Put it through its paces based on a defense-in-depth model. Take advantage of all the information Microsoft and others have made available in places like GitHub, where there is a vast repository of valuable detections that can be tweaked depending on your environment.

It makes it a lot easier to get started. Many people approaching security with a blank canvas aren't sure where to go. There are a lot of valuable resources and information available.

We are a security service provider, and we are using Microsoft Sentinel to provide managed security services to our customers.

The visibility that it provides is very good because Microsoft is a front runner in threat intelligence and cybersecurity operations. They have their own threat intel team that is very active. They are actively covering any new threats that are coming into the landscape. They are adding detections, queries, playbooks, and other things related to new threats. They have out-of-the-box integrations, and the coverage of new threats is very fast in Microsoft Sentinel.

It helps us to prioritize threats across our enterprise. Whenever we onboard new customers, after integrating all of their log sources, we actively check for any latest threats being present in their environment. Microsoft Sentinel is natively integrated with all the latest threat intel available, which makes it very valuable for us. It is a SaaS application. So, it is very easy to deploy this solution for new customers to cover their security needs.

In addition to Microsoft Sentinel, we use the EDR solution from Microsoft, which is Defender for Endpoint. We also use Office 365 for email purposes. We have integrated Microsoft Sentinel with these products. In Microsoft Sentinel, there are connectors specifically for this purpose. All the logs from these products are available in this SIEM tool, and it is easy to manage everything from a single pane of glass.

Even though Microsoft Sentinel is a cloud-native product, by using the connectors, you can easily integrate your on-prem and cloud resources with Microsoft Sentinel. Most of our tools including On-Prem are currently integrated with Microsoft Sentinel.

It is very helpful in automating tasks that otherwise require manual intervention. There are two ways to do automation. One is by using the automation rules, and the other one is through playbooks. Automation rules can be used to automate simple tasks, such as automatically assigning an incident to a particular analyst who should be monitoring the incident. By using automation rules, you can automate various tasks, such as setting the severity of the incident and automatically changing the status of the incident.

Playbooks can be used to automate high-value tasks, such as blocking a malicious IP in the firewall or blocking a particular user in Azure Active Directory. All such tasks can be automated through playbooks.

There are lots of things that we have found valuable in this solution. Mainly, this is a cloud-native product. So, there are zero concerns about managing the whole infrastructure on-premises.

Kusto Query Language that powers Microsoft Sentinel is another valuable feature. It is a very fast and powerful language.

The integration with different ticketing tools like Jira, ServiceNow, etc. is also a great plus point.

Besides that, the addition of new features to the product is very fast. The overall customer experience in terms of using their Cloud Security Private Community and being able to provide our feedback and suggestions is good. They take the feature requests on priority, and whenever possible, they add the new features in the next version of the product.

Currently, SPAN traffic monitoring is not available in Microsoft Sentinel. I have heard that it is available in Defender for Identity, which is a different product. It would be good if  SPAN traffic monitoring is available in Microsoft Sentinel. It would add a lot of value. It is available in some of the competitor products in the market.

Also Reporting feature is missing in Sentinel. Currently, we have to rely on PowerBI for reporting. It would be great if this feature is added. 

We have opted for the pay-as-you-go model, which doesn't come with free support. If some limited free support was available with the pay-as-you-go model, it would be good. 

I have been using this solution for about one year.

There is a great community for Microsoft Security, and we mostly rely on this Microsoft Security community and Microsoft Q&A forums for support. Currently, we are using the pay-as-you-go model which doesn't come with free on-call support. It would be good if some free support was available, even if in a limited way, with the pay-as-you-go model. So, we haven't used their on-call support yet, but their support from the community has been great. Because of that, I would rate their support an eight out of ten.

Positive

Before Microsoft Sentinel, we were not working with any other cloud-native SIEM solution. 

It's important to understand the daily data ingestion required for you or your customer (in case you're an MSSP). There are price tiers starting from 100 GB/day ingestion. But if your ingestion varies too much or your ingestion is lower than 100 GB, you may go for the pay-as-you-go (Per GB) Model. In the case of pay-as-you-go, it is about how closely you monitor the ingestion of each GB of data and how effectively you limit that ingestion. If you don't effectively monitor the ingestion, the price may be too much, and you may not be able to afford it. You should be very clear about your data usage. Sentinel provides great granular visibility into data ingestion. Some of the data might not be relevant to security. For example, basic metrics or other log data might not be very useful for monitoring the security of an enterprise. If you do the right things and limit the ingestion of data, its license plan is perfect, and you can save lots of money.

We considered AlienVault, QRadar, and other solutions, but we didn't try those solutions before opting for Microsoft Sentinel because Sentinel was having fantastic reviews and it was our perfect first choice for our Cloud-Native SIEM tool. So, we decided to first try Microsoft Sentinel. If we had not found it satisfactory, we would have tried other solutions. After doing the trial version for 30 days, we were very happy with Microsoft Sentinel. The addition of new features was also very fast. So, we decided to go ahead with the product.

Microsoft Sentinel is an awesome SIEM/SOAR tool for customers with active Cloud presence. Even for on-prem customers, it is providing great flexibility for integrations. 

I would rate Microsoft Sentinel a nine out of ten.

Sentinel gathers data from the organization's entire ecosystem, not just the local network. I like having the ability to investigate and respond quickly to threats from one place. It's fun to use. Sentinel has an intuitive, user-friendly way to visualize the data properly. It gives me a solid overview of all the logs. We get a more detailed view that I can't get from the other SIEM tools. It has some IP and URL-specific allow listing

Sentinel comes with multiple good playbooks for automation and other valuable things that we use. It automatically gives us alerts in our ticketing platform, ServiceNow. 

If you're using other Microsoft security tools, it's better to use Sentinel instead of other SIEM solutions. It reduces the time spent on threat hunting because it uses an SQL database and SQL custom query language. It helps me analyze the data properly because I can view all the events. Sentinel has helped me multitask. 

The most valuable feature is the integration with other Microsoft security tools. It's an Azure product, so it integrates seamlessly with tools like Microsoft Defender for Endpoint, Defender for Cloud Apps Security, and Defender for Identity. 

It collects all the logs from these solutions and correlates the data well. If I need to check a particular event or log, I can easily review this from one portal, which is something I can't do in another SIEM tool. Sentinel has a graphical view that shows every team the information they need. 

It will easily give us the entities, events, or accounts that are directly involved in any particular security alerts. It has good usability. Sentinel comes with multiple different connectors. We only need to select the log sources, and the connectors automatically load.

We can customize the visibility based on the organization's rules and policies. We establish the desired rules and log sources. Most of them are from Azure-based products, not firewalls or point system-based accounts. Initially, most of the security alerts are false positives, and we need to do some fine-tuning. 

Sentinel can be used in two ways. With other tools like QRadar, I don't need to run queries. Using Sentinel requires users to learn KQL to run technical queries and check things. If they don't know KQL, they can't fully utilize the solution. 

When we're dealing with freelancers and new employees, they often have problems analyzing some things. An expert can realize all of Sentinel's advantages, but most organizations are constantly hiring new staff, who need to learn KQL before they can use this. 

I have used Sentinel for the last two years. 

I've never experienced lag, but it crashes sometimes. One disadvantage is that it collects tons of logs, so when we create reports, it isn't easy to download a month of reports in one day. We have to spread it out across 15 days. 

The scalability is good. You can scale it out by adding other tools.

We haven't needed to contact Microsoft support about Sentinel because we haven't had any significant downtime. Our other SIEM tools sometimes went down and we had to contact support multiple times. Sentinel always provides solid availability, and it's ready to take our logs.

I have used IBM QRadar and Splunk. I prefer Sentinel for threat hunting because the process is more visual. QRadar and Splunk are better for user interaction. 

I rate Microsoft Sentinel eight out of 10. I think a single-vendor strategy makes sense if you're primarily using Microsoft tools. It simplifies things because you only have one support portal, and engineers are easily accessible. If I'm working with security tools from multiple vendors, it can be hectic because the tools are made differently and have different architectures. 

I'm into monitoring and deploying. When an incident occurs in Sentinel, we try to triage it then investigate it, then we try to gather more details about it through other blades in Sentinel. We try to gather more information about the IP address, and user details from the Sentinel itself, as well as Active Directory. 

They have good playbooks or logic apps to take action on behalf of the user. They're automated actions that we configure for when a particular condition occurs. It reduces human effort a lot and performs tasks on its own. 

There is an option wherein we can add multiple usernames or any details in multiple numbers, and we can just use that instead of manually adding all the names.

When it comes to threats, every environment is different, and the data connectors are different. So it depends on what data connectors are configured to your environment. It could be specific to that. However, Sentinel is a pretty good product. It does threat detection very well. Depending on the user, and how he configures it, Sentinel will do a good job in delivering the output.

We already have priority-based use cases which we set during the creation of any use cases for any threat detection. It also allows us to change the priority whenever a threat occurs. Currently, in the environment in which I am working, we don't manually change the severity or the priority whenever the threat occurs. We will deal with it in its original form. However, it could be a good feature for us to use and also very helpful to set the priority level whenever it is necessary. 

There is a specific incident blade that we can respond from. Or we have log analytics in Sentinel in which we can do threat hunting. We have various ways to gain visibility.

Threat intelligence is under development. It's not completely ready, however, it is a very good feature and can find multiple threats. It's completely managed by Micorosft. So far, it's a very good feature. 

The UI of Sentinel is very good and easy to use, even for beginners. 

It's very easy to deploy a new use case. We can create them very easily. Adding connectors is simple. 

The preview mode is good. Sometimes it helps us pick up on malicious threats. It can sometimes provide false positives as well. For the most part, we can deal with it; it's good. That said, it's a work in progress. 

There are good guides that allow us to easily add new features to our environment. 

Workbooks allow us to display charts and help us provide very useful visuals. 

Automation is very good.

The solution has helped us to save time. 

I'm aware that we can have one centralized dashboard. We can view multiple dashboards in one central place. We can merge all tables and visualizations into one single pane of glass. It's easy to configure. However, we do not really work with a consolidated dashboard. We have a few for the reports. 

The solution has decreased the time to detection and time to respond via custom use cases. However, I cannot quantify the exact amount of time saved. On average, it saves 30 to 40 minutes a day. 

We're satisfied with the comprehensiveness of the security protection. That said, we do have issues sometimes where there have been global outages and we need to raise a ticket with Microsoft. Those have become repetitive and happen more often. Still, there are many choices and features, which is useful.

There are some false positives.

When an incident occurs, it will just be displayed on your screen. However, if they had some sort of sound or tone to alert the analyst, that would be ideal. It would help them notice when something is triggered. 

I've been using the solution for two years and five months. 

There are no issues or outages. It's 90% to 95% stable. 

Our environment is mostly in Europe and there are multiple end-users.

Since this is just monitoring and threat detection, it can scale well. We can add new servers and increase the amount of logs flowing into Sentinel easily. There's no issue with that. 

Microsoft is quick to respond depending on the severity of the ticket. It's usually fixed within two to three hours maximum. The tech support understands the product well. 

Positive

I have not used any other products.

The maintenance is minimal. If there is a global issue, we'd have to raise a ticket with Microsoft. 

I'm not aware of the exact costs involved. 

I did not evaluate other options before using this solution. 

We do not use more than one Microsoft security product. We don't work with Defender, for example. 

We do not yet use it to ingest data from the rest of our ecosystem. We have seven to ten people that work directly with the product.

This is a good tool with a lot of good features. 

I'd recommend the product. The UI is good which makes it simple for new users. It will make it easy to train new engineers.

It's important to go with a best-in-breed rather than a single vendor. If there is any issue with the monitoring with one solution, it's good to have a backup option that might pick up what the other could miss. Having more than one solution - and different vendor options - allows you to have an "option B".

I'd rate the solution seven out of ten. There are still a lot of improvements that can be done. 

I work for a security operation center. We use Microsoft Sentinel to monitor the tenants of our customers and provide automated investigations and feedback and alerting.

If something happens or if we get an alert, we also use it to investigate further. We do a deep analysis of the logs that we ingest from our customers. We also have many automation rules built into Microsoft Sentinel to reduce the noise and not-true positive alerts.

There is the ease of setup and ease of use. When we get new customers, we do not need to go onsite, build a system inside their on-premise network, and spend a lot of time setting up the systems. We can easily deploy a new Sentinel solution for a customer with automated templates, which benefits a lot in onboarding new customers. Because we have integrated it with many other security solutions from Microsoft, we can also perform many actions for which we otherwise would have needed VPN access or would have had to go to the customer site. So, the main benefit is that we can easily do anything from anywhere without having to spend much time setting up and onboarding.

We have combined it with other tools such as Microsoft 365 Defender Suite. With all tools combined and the customization that we have developed, we get pretty good insights into possible threats. It all depends on the logs you ingest. If you ingest the right logs, you can get very meaningful insights.

It helps us to prioritize threats across the enterprise. It does that in a very good way. It prioritizes the threats based on multiple factors. If multiple similar incidents happen or suspicious related activities happen at the same time, the incident gets a high priority because that's likely to be a real threat, but it also ingests the priorities that come from the other tools. You also have the ability to adapt priorities because each customer is different. Each business is different. We give our customers a standby for tickets that come in with priority two or higher. Microsoft Sentinel also gives us the chance to lower priority on some cases or upper the priority on some cases depending on the business use case of the customer.

We are a Microsoft security company, so we try to use as many Microsoft security tools as possible. We have Microsoft Defender for Cloud and Microsoft Defender for Office 365 as well. They are integrated into Defender 365 currently. We use the compliance portal. We use Microsoft Purview. We use Microsoft Sentinel. We use Microsoft Defender for Key Vault. We try to use as many security solutions as possible.

We have integrated these products with each other, and we have succeeded in it as well. Each product is at least integrated with Microsoft Sentinel by either using the way provided by Microsoft or a custom way to ingest data. We have integrated Defender 365 and other tools as well. We try to ingest alerts only from one place, if possible. We have integrated everything into one portal, and we ingest the data only from that portal. The integration for Microsoft solutions mostly works natively, but some of our customers have third-party solutions that we can integrate as well.

It's very important that Microsoft solutions work natively. When they work natively, you can have more built-in functionality for them. They are much more maintainable, and it does not take as much time to set up versus when you have to make a custom integration to something.

Microsoft Sentinel enables us to ingest data from the entire ecosystem. We can make custom integrations. If you have Linux machines or on-premises networks, you can set up a log forwarder inside the network and ingest the data that way into Microsoft Sentinel. There are many possibilities to ingest data from all locations, which is necessary for an XDR/SIEM solution. This ingestion of data is one of the most important things for our security operations because if we cannot ingest any data, we are partially blind on that side.

Microsoft Sentinel enables us to investigate threats and respond holistically from one place. You do have to learn the KQL language, but it's similar to many other languages that are created by Microsoft or adopted by Microsoft. It's not that hard to learn. If you know it well, you can easily perform analysis on a whole bunch of data, whereas without Microsoft Sentinel, you would have to perform the analysis at many different places. Microsoft Sentinel gives you the possibility to do it just in one place.

We do not use all the functionalities of Microsoft Sentinel. For example, hunting queries are something that we do not use often, but their threat intelligence is updated quite regularly. We have tried it in Purview, which is a separate threat intelligence license that you can buy from Microsoft, but Microsoft also provides basic rules that alert on multiple threat indicators they detected earlier. They are very useful at the beginning sometimes. You have to remove those rules yourself as soon as they get outdated. The alerting that we get out of the threat intelligence provided by Microsoft itself has been valuable many times for our use cases.

Microsoft Sentinel helps automate routine tasks and the finding of high-value alerts. If we see many recurring alerts that are always suspicious but not really malicious, we can build our own automation rules that auto-close these alerts or automatically lower the priority on those alerts so that we are not getting too many notifications from alerts that are not worth investigating. It's really easy to do that. You can do it in many ways. To do the automation, there is a user-friendly interface. There are just drag-and-drop steps. It helps a lot, and it's easy to implement as well.

It has helped to eliminate having to look at multiple dashboards and have one dashboard for the analysis part, but for the response actions, it hasn't eliminated that because we have to log on to the Microsoft Defender security portals to perform most of those actions. For the analysis part, the alerting part, and the automated investigation part, this is the solution.

Its threat intelligence helps prepare us for potential threats before they hit and take proactive steps. For example, as soon as the Log4j vulnerability was known to the public, we immediately got alerts. We were able to take immediate action and remediate the vulnerability. We immediately knew how to prioritize our customers because we knew which customers already had active exploitation. Most of the time, such attempts were blocked, and if they got through, then the machine was luckily not really vulnerable, but it has been very helpful at that point to immediately assess the criticality for our customers. The attempts were not successful for many reasons. It also blocked them immediately.

It has saved us time. Especially because of the automated investigation part, it saved us a lot of time. We also have automated reporting, which also saves a lot of time each month. We provide our customers with a monthly report. If we had to do it manually and gather data from many different places, it would take a lot of time. Even if we had to fill it in manually in Microsoft Sentinel, it would take a lot of time, but because Microsoft Sentinel already ingests all of the data we use in our reports, we were able to write an integration with Microsoft Sentinel, which takes care of 75% of our reporting, and then we only have to do our analysis part. The data is already filled in, which saves a lot of time each month. The time savings went from one day per customer to one hour or two hours. For nearly fifteen customers, it was fifteen days, and now, it's 30 hours, which is more or less four days. It saves a lot of time each month that can now be spent on improving our service or performing deeper investigations on newly known threats and proactively act on them.

It hasn't reduced our time to detect because we have been using Microsoft Sentinel from the beginning. So, we always had the same response time because we only used Microsoft Sentinel for our alerting. It integrates well with Atlassian tools and ServiceNow tools, which gives us the ability to be alerted very fast on something, and then we can act immediately.

It's easy to use. It's a very good product. It can easily ingest data from anywhere. It has an easily understandable language to perform actions. You can use the entire Azure cloud to perform automated actions and automate investigations. The possibilities are more or less limitless because you can integrate Microsoft Sentinel with many resources inside the Azure cloud. If you integrate the security tooling with it, you can also make use of the data that Microsoft gathers from all Windows operating systems about malware, for instance, or about possible attacks. They ingest that data from so many sources, and you can make use of it. It helps a lot in discovering new vulnerabilities. We can almost immediately investigate them because Microsoft is always on top of things.

Threat intelligence could be better because we have had some cases where we got alerted online for many things all of a sudden. It was because some updates happened in the background, and we didn't agree with the use cases or how they were built. That part of threat intelligence could be a little better.

We have also had incidents where other tooling got an update but Microsoft Sentinel didn't update.

Microsoft Sentinel is a simple and straightforward solution. It could have a better API to be able to automate many things more extensively and get more extensive data and more expensive deployment possibilities. It can gain some points on the automation part and the integration part. The API is very limited, and I would like to see it extended a bit more.

We have recently turned on the bi-directional sync capabilities of Microsoft Defender for Cloud. It works pretty well, but sometimes, it just syncs only the incidents and not the alerts behind them or the other way around. That was the only thing. That was a recent complaint we had. Other than that, it works well.

I've been using Microsoft Sentinel for nearly two years.

It's very stable. We have many different Microsoft Sentinel instances running. Apart from some cleanup and maintenance, they all are running without any issues.

It's very scalable. As long as you send the right logs, it can ingest them perfectly, but, of course, the more logs you ingest, the higher the price, so you have to be very careful and very concerned about the logs you are ingesting in Microsoft Sentinel. You have to make sure that the logs that you ingest provide value for your security and are not useless.

I have not contacted them regarding Microsoft Sentinel, but I have contacted them for other solutions. Sometimes, we can't figure something out ourselves or we have questions about the new features that are made public. If we have a question or need assistance in any way in providing support to our customers, we can count on support to help us. I have not had a bad experience with them. We are also a Microsoft partner, so we get quick replies and have direct contacts within Microsoft sometimes for some cases. If we need support, they always help us very well.

Overall, I would rate them a seven out of ten because sometimes, they take a long time or you get redirected many times to another colleague before the issue is resolved, but in the end, they always help us out, and everything is fixed.

Neutral

In my previous job, we worked with local or on-premise systems, but the security monitoring was not that strong at that time. This is my second job, and in this job, I've only worked with Microsoft Sentinel.

I worked on one of the deployment scripts we use for our customers, but I was not involved in its initial deployment. I deployed it once for a customer by using the Azure resource manager template that I built. It was rather complex because the documentation was not up to date or correct at that time. When working with Microsoft Sentinel, sometimes the documentation is not as up-to-date or complete as it should be in my opinion.

The number of people involved in its deployment depends on the size of the customer, but usually, one or two people from the team do the deployment. One person works on the deployment of Microsoft Sentinel, and the other one usually works on the deployment of other components, such as analytics, automation, etc.

It does require maintenance. In order to stay up to date and keep evolving on the threat landscape, you have to keep looking for new analytic rules, new investigation techniques, and new automations. You have to constantly improve your Sentinel in order to stay on point and detect and have complete detection scenarios. Sometimes, the rules that are provided by Microsoft or the settings or conditions that are provided by Microsoft get deprecated or get a new update. You have to follow that up as well in order to stay up to date with the things Microsoft changes or recommends.

If you want to use Microsoft Sentinel, you should start thinking about the logs that you want to ingest. You should identify the ones that are important and also think of the use cases and what you want to detect from those logs. If you make the right choices on these two things, the setup and the integration with other tools will be very easy because you know from where you want to ingest logs and you know how to create analytics rules, automation rules, and things like that to detect the things that are critical or important to the security of your business.

To a security colleague who says it’s better to go with a best-of-breed strategy rather than a single vendor’s security suite, I would say that with a single vendor, we can integrate everything like a single product. We use Azure Active Directory, so we can easily secure authentication across multiple products and manage access permissions. On top of that, we have a single pane of glass where we can investigate and perform analysis in a very easy and user-friendly way, which saves a lot of time. We don't have to click through many different portals and know where to look each time. We don't have to learn the configuration, the setup, and the actions we can perform in each system because everything has the same interface. We only have to learn the things that Microsoft provides and not different products. The single pane of glass saves time and makes it much easier to investigate and respond and secure the environment.

Overall, I would rate Microsoft Sentinel an eight out of ten. I'm very happy with it, but no product is perfect. It can improve on some points, but overall, it's very good.

We use Sentinel to monitor logs, build alarms, correlate events, and fire up specific automation boards in the event of a security incident. 

Sentinel creates a focal point for cybersecurity incidents, so it's much easier to correlate logs and incidents to get a more comprehensive view of our security posture. Microsoft provides many educational resources, so onboarding new people is easy. 

It took us about a month to realize the benefits of Sentinel. Integrating all the Microsoft security products into the solution was straightforward. It seamlessly integrates with Microsoft Logic Apps, so it's easy to develop custom playbooks and automate many manual tasks. 

Automation has made us more efficient and effective because we're free to focus on priority alerts. Sentinel has reduced the time spent on menial security tasks by 30-40 percent. Sentinel consolidates our dashboards into a single XDR console, one of our strategic goals. We're moving all of the data into Microsoft Sentinel to create a single point of truth for security incidents.

Microsoft provides some threat intelligence for significant incidents. They provide us with remediation and mitigation controls we can implement to react to these potential threats much faster.

I like the ability to run custom KQL queries. I don't know if that feature is specific to Sentinel. As far as I know, they use technology built into Azure's Log Analytics app. Sentinel integrates with that, and we use this functionality heavily.

Threat prioritization is a crucial feature. It already has them in order, so we know we should investigate high alerts first and move down the line to the less urgent ones. 

We use all of the other Microsoft security solutions in addition to Sentinel. They all can be integrated together seamlessly to deliver comprehensive threat detection and response. 

I would like to see additional artificial intelligence capabilities. They're already working on this with new features like Microsoft Security Copilot. This will help us investigate incidents much faster. 

When we pass KPIs to the governance department, there's no option to provide rights to the data or dashboard to colleagues. We can use Power BI for this, but it isn't easy or convenient. They should just come up with a way to provide limited role-based access to auditing personnel 

I have used Sentinel for two years.

We haven't experienced any downtime, so I think Sentinel is highly stable. 

Sentinel runs on the cloud, so it scales automatically. 

I rate Microsoft's support a 10 out of 10. They can connect you with the developers, and you get answers quickly. 

Positive

I also worked with RSA enVision at my previous company. Sentinel has advantages because of its tight integration with the Microsoft ecosystem. It's effortless to set up because you don't need specific connectors. Sentinel works out of the box. It makes sense for a company that primarily works with Microsoft products to use Sentinel for security monitoring.

Sentinel runs on the Microsoft Azure Cloud, so it was easy to set up. It took about two days to set it up. You start by integrating the Microsoft security solutions using the available connectors and move on to the firewall, SysTalk databases, and application-specific logs. 

It's a bit more complicated to come up with custom rules and alarms, so that's the last part of our implementation strategy. We completed the deployment with two or three people and the help of Microsoft support. Because Sentinel is deployed in the cloud, it doesn't require any maintenance. 

Our ROI comes from automating lots of tasks. 

Microsoft Sentinel is pretty expensive, and they recently announced that they will increase the price of all Microsoft services running in Azure by 11 percent. Luckily, I'm not responsible for the financial side. For one of my clients, the estimated cost is 880,000 euros for one year. There are additional costs for the service agreement. 

I rate Microsoft Sentinel an eight out of ten. I recommend taking advantage of the virtual training before you implement Sentinel. Familiarize yourself with the product, dashboards, features, integration, etc., before you decide to use it. 

A single-vendor strategy is preferable because it's easier to integrate them. Otherwise, it can get complicated.

Our use cases range from more complex configurations, looking at things like playbooks, workbooks, and threat-hunting, for which we rolled out architectures in some departments in the Government of Canada, to a more streamlined functionality and looking at things from a correlation perspective. 

We work in tandem with a couple of departments that have products called cloud sensors and those sensors feed telemetry into Sentinel. In its simplest form, we're using it for the ingestion of all that telemetry and looking for anomalies.

The anomalous behavior can include anonymous IPs and geolocation that might indicate bad actors are trying to access a system. If I'm located in Ottawa, Ontario and somebody from Russia is trying to access our tenant, that's going to be pretty suspicious.

Just like the US government has FedRAMP, there is a similar approach, here, for the Government of Canada where the funding for projects takes a cloud-first approach. Most of the departments in the government are now on some kind of cloud journey. When I look at the various projects I've worked on, every single one, to some degree, has an IaaS in Azure environment, and most of those deployments incorporate Sentinel and the log analytics workspace into the solution.

Sentinel helps automate the finding of important alerts as well as routine tasks. When your KQL queries are well-defined, and your threat hunting becomes more routine for parsing through a volume of ingested information, it becomes more of an established process. There would likely be some kind of documentation or procedures for how Sentinel would be managed. The idea is to catch any threat before it actually impacts your organization. Using Sentinel workbooks and playbooks and doing threat-hunting to find things before they actually affect a particular system is the optimal approach. It may depend on the size of the team that is supporting the tool and the knowledge level required to appropriately configure the tool.

I have one department that has quite a mature and robust Sentinel implementation, and they are absolutely doing that. They're using threat-hunting and the ability to create rules to be proactive.

A fully functioning Sentinel system configured properly so that you're doing advanced threat-hunting and trying to catch malware and other kinds of attacks before they impact your systems, could result in enormous cost savings if you're able to identify threats before they actually impact you. I'm sure that Sentinel has saved money for most departments in terms of forensic, digital investigations. But it would be hard for me to put a dollar figure on that. As the Government of Canada is becoming more capable of managing this system, the ability to leverage all of the bells and whistles to help to create a better security posture, and to catch things in advance, will absolutely result in dollar savings.

Similarly, for time to detection, a fully deployed Sentinel system that is properly managed and has a good, robust configuration, would absolutely save time in terms of pinpointing systems where a problem may exist, and employing alternative tools to do scans and configure reviews. But specific savings would depend on the department, the size of the team, and the configuration of the tool.

There are some very powerful features in Sentinel, such as the integration of various connectors. We have a lot of departments that use both IaaS and SaaS services, including M365 as well as Azure services. The ability to leverage connectors into these environments allows for large-scale data injection. We can then use KQL (Kusto Query Language) queries. It queries the telemetry for anomalies. The ability to parse out that information and do specific queries on it, and look for very specific things, is quite a valuable function.

The large-scale data ingestion and the ability to use KQL queries to establish connectors into various data sources provide very expansive visibility. With playbooks into which you incorporate rules, you can be very granular or specific about what you're looking for. It provides a great deal of visibility into that telemetry coming in from various services across your tenant.

In terms of data ingestion from an entire ecosystem, there might be some services for which Microsoft has not built a connector yet for Sentinel. But for most of the major services within Azure, including M365, those connectors do exist. That's a critical piece. As a SIEM, the way that it identifies anything anomalous is by correlating all those sources and searching the telemetry for anomalies. It's critical to ensure that you can ingest all that information and correlate it accordingly.

The comprehensiveness of Sentinel's security protection is highly effective and it scales well. It has the ability to do automated responses that are based on rules and on Sentinel's ability to learn more about the environment. The AI piece allows for behavioral and learning processes to take place, but the underlying logic is in the rules that you create via playbooks and workbooks. That whole functionality is highly effective, as long as you have good KQL literacy, how your alerts are configured, and where your alerts are configured. Are they via email or SMS? There are a lot of variables for how you want or expect Sentinel to behave. It's quite a comprehensive architecture to make sure that you've got all those pieces in place. When configured properly, Sentinel is a very powerful tool, and it's very beneficial.

My only complaint about Sentinel has to do with how you leverage queries. If you have good knowledge of KQL, things are fine. But if you're looking to use canned queries, the interface could be a little more straightforward. It's not immediately intuitive regarding how you use it. You have to take a canned query and paste it into an operational box and then you hit a button. Then it does the analysis of the telemetry. If things could be improved anywhere, it might be there. They could improve the ease of deploying these queries.

I have been using Sentinel since 2018.

Sentinel is very good if you have the right support tier in place. If you don't have the right support tier, then it can become quite laborious to find a technician who is knowledgeable, because the tier-one support might be out-of-country. You have to pay for the ability to get to a senior guy who is quite knowledgeable. That's an area of cost that may be impactful to the proper operation of the tool itself. But when you do talk to somebody who's knowledgeable, it's great.

Positive

It's expensive, but it's beneficial.

Because of the way that the Government of Canada allows access to the Azure marketplace, we don't typically employ other cloud SIEMs. However, many departments of the government use on-prem SIEMs. When I consider the licensing and the functionality for those on-prem SIEMs, Sentinel is fairly pricey. That being said, for an Azure tenant, it's really the only game in town, unless you're pulling in information or you're exporting information from Sentinel to a third-party source on-prem for further analysis or storage.

Cost-wise, Sentinel is based on the volume of information being ingested, so it can be quite pricey. The ability to use strategies to control what data is being ingested is important.

Because it's expensive, I've seen other departments that have on-prem SIEMs that reanalyze telemetry that is exported from the Azure cloud. It's not like-for-like, though.

Many organizations leverage the MITRE ATT&CK framework. Within MITRE there are all kinds of tactics that could be brought to bear on any unsuspecting department or target. Or they align with something like OWASP. But with Sentinel, you're able to delineate what categories you want to prioritize. For anything web-based, because everything is based on APIs and is based on a web interface, you might want to prioritize OWASP-based threats. But if you look at things like APTs, advanced, persistent threats, and various bad actors that MITRE categorizes, that gives you a really good source of information in terms of what to prioritize.

There are a lot of Microsoft security products: Defender for Cloud, Security Center, Azure Monitor. On the SaaS side, we leverage Compliance Manager. And within the dashboards for M365, you've got the ability to leverage policies. For some clients I've worked on, we have things like DLP policies, to prevent unauthorized exfiltration of data. But for IaaS, where Azure typically resides, Defender for Cloud is a big one.

With the use of connectors, if you're looking to provide data telemetry from various services back into Sentinel to do threat-hunting, it is quite a straightforward process. If you're looking to look at things like logging and auditing and how storage accounts integrate, that's a bit more complex, but it's not rocket science. It's certainly quite feasible.

Because they're all services incorporated into Azure, and into IaaS from a broader perspective, there's fairly straightforward integration. Everything is API driven. As long as you can take advantage of that within your dashboard and your admin center, you can enable them very simply through that. If you're looking for historical data through login auditing, it's a matter of parsing through some of that information to get some of those key nuggets of information. But the broader ability to spin up a bunch of services through Azure and have them communicate and work together to build a better security posture is very straightforward.

Cloud platforms, whether Microsoft or AWS or Google, are always in flux. There are always services coming down the line, as well as updates or upgrades, and refinements to these services. Very rarely do you find a static service. When I look at the comprehensiveness of Sentinel from when I started to use it back in 2018 and through to early 2023, there have been a fair number of changes to the functionality of the tool. There are more connectors coming online all the time. It's evolving to make it more and more comprehensive in terms of what kind of information you can pull into Sentinel. It's more and more comprehensive as time goes on; the tool just improves.

Microsoft Defender for Cloud's bi-directional sync capabilities are important in the following way. If you have an issue that shows in Defender for Cloud, an incident on your dashboard, and you look into Sentinel and see the same alert has been triggered, after someone on your team looks into it and fixes it, if bi-directional is not enabled, you will still have the alert showing. If someone is looking at the Defender for Cloud dashboard, that alert will still show as active. That's why it's important to have bi-directional sync. It helps make sure that people work on the right cases.

Sentinel enables you to investigate threats and respond holistically in one place. It gives you a central repository where you can have a historical view and see the access point where something started, where it went, and how things were accessed. For instance, if someone was anomalously accessing keywords, with everything in one place you can see where it started, where it went, who was involved in it, what kind of endpoints were involved, what IP address was involved, and what devices were involved. In this way, you have complete historical data to investigate the root cause.

Previously, I worked with a number of different tools to pull the data. But having one pane of glass has obviously helped. When you consider the time it takes to go into each and every dashboard and look into alerts, and take the necessary actions, Sentinel saves me a minimum of 15 minutes for each dashboard. If you have three to four dashboards altogether, it saves you around one hour.

And when it comes to automating routine tasks, if you want to notify the right people so that they can look into a P-1 incident, for example, Sentinel can automatically tag the respective SOC or security incident teams through a team chart and they can directly jump into a call.

Another point to consider is multi-stage attack detection. We have a granular view into the incident. We can investigate which IPs, user entities, and endpoints are involved in the alert. If you have to look at multiple, separate points, it could take one hour to see what happened at a particular point in time. With Sentinel, we can directly look into a certain person and points and that saves a lot of time. And then we can take action on the incident.

Among the valuable features of Sentinel are that it 

• has seamless integration with Azure native tools 
• has out-of-the-box data connectors available
• is user-friendly
• is being expanded with more updates.

The visibility into threats that the solution provides is pretty good. We can see a live attack if something is going wrong; we can see the live data in Sentinel.

I work on the complete Azure/Microsoft stack. With Azure native, we can integrate the various products in a few clicks. It doesn't require configuring a server, pulling of logs, or other heavy work. It's very easy, plug-and-play. The data collectors are available with Azure native so you can deploy policies or it will take care of everything in the backend. If various tools have different priorities for issues, monitoring everything is a hectic task. You have to go into each tool and look into the alerts that have been triggered. It's a big task. If you can integrate them into a single pane of glass, that helps you to find out everything you need to know.

And in terms of the comprehensiveness of the threat protection that these products provide, I would give it a 10 out of 10.

Microsoft Sentinel enables you to ingest data from the entire ecosystem and that connection of data helps you to monitor critical resources and to know what's happening in the environment. At a minimum, we should monitor the servers that are critical in the environment.

It also has hunting capabilities so that you can proactively hunt for things, but a different team looks after that in our organization.

In terms of features I would like to see in future releases, I'm interested in a few more use cases around automation. I do believe a lot of automation is available, and more is in progress, but that would be my area of interest.

I have been using Microsoft Sentinel for more than two and a half years.

It's a stable solution.

It's a scalable model but as you scale up you pay for it.

Microsoft technical support is responsive and helpful. And their technical documents are pretty detailed and well-explained.

Positive

The initial deployment was pretty straightforward.

The number of people involved in the deployment is completely dependent upon the environment and the access we have. If there's something to be done with a third-party application—for instance, Cisco Meraki or ASA—for those, we require support from the networking team to open up ports and forwarding of logs from the firewalls to Sentinel. If it is a native Azure environment, we don't need any support.

As for maintenance, if there are any updates they will pop up in your alerts and you can then upgrade to the latest version. It doesn't take much effort and there is no downtime. You simply update and it takes a few seconds. If someone is experienced, that person can handle the maintenance. If the environment is very big and it requires injecting more logs, then it requires some helping hands.

The pricing is fair.

With a traditional SIEM, people are required for SOC operations and investigations and they require licenses. With Sentinel, people in SOC operations are still required to investigate, but we don't need any licenses for them. With a traditional SIEM, you pay a lump sum for licenses. But with Sentinel, it's pay-as-you-go according to the amount of data you inject.

I would recommend Microsoft Sentinel.

It's always good to compare against other tools when it comes to the value, to get an idea of what you are paying for. Compare the market strategies and the new capabilities that are coming out and whether you're able to unlock the full capabilities or not. Double-check that. As for best-of-breed versus one vendor, you should stick with one vendor only and take whatever they gave.

Microsoft Sentinel is basically a major log, on top of which you can build queries that can analyze the data you get. It's used to build up security operations centers. In addition, it is a SIEM and SOAR solution.

The first benefit is that you have one place to close incidents. That's definitely an advantage. 

Another benefit is KQL, Kusto Query Language, and the analytic rules with which you can spot suspicious behavior of all kinds. It's definitely a step up when it comes to security. You see the benefits almost instantly.

In addition, automation helps prioritize what needs to be looked at, and what can just be closed and forgotten.

And when you combine the threat intelligence with Defender for Endpoint's recommendations, it's a really strong way to protect things or be proactive when it comes to security, with the CVEs, et cetera.

Overall, our Microsoft solution saves time. Without it, you might have to navigate six or seven portals, but with it, you only have to look at one place, and that saves some time. Most of the time, it eliminates having to look at multiple dashboards and gives you one XDR dashboard. Ideally, that should make working with IT security easier. It also decreases the time it takes to detect and respond.

As a consultant, none of the customers I work for has been hacked or has been close to being hacked. That would be the best way to judge if it saves money because just putting Sentinel on top of all these security products doesn't save you money. It's possible it saves you money. 

I like the unified security console. You can close incidents using Sentinel in all other Microsoft Security portals when it comes to incident response.

The solution helps prioritize threats across your enterprise and that is quite important. There is a concept called "alert fatigue," and Sentinel can also cause that because it detects so many false positives. But usually, the high and medium risks it identifies are things you need to take a look at. So prioritization is quite important.

We also use Defender for Cloud, Defender for Endpoint, and Defender for Cloud Apps. It's quite easy to integrate these Microsoft products because they can easily communicate with other Microsoft products. The tricky part is to integrate other vendors' products, like Cisco or Linux, with Microsoft Sentinel. The actual integration is easy, but they generate a lot of data. But with its entire Defender suite, Microsoft is trying to cover everything in Azure and that is a really strong point.

Sentinel enables you to ingest data from your entire ecosystem and that is vital, but sometimes it's a bit hard to figure out what data you actually need.

Also, the UEBA is a neat feature.

The built-in SOAR is not really good out-of-the-box. The SOAR relies on logic apps and you almost need to have some kind of developer background to be able to make these logic apps. Most security people cannot develop anything, but if you want to make full use of the SOAR part of Microsoft Sentinel, you need to be able to develop these logic apps. You can say, "Okay, that's simple," but it's not simple for someone who doesn't develop.

Also, the bi-directional sync in Microsoft Defender for Cloud should be enabled out-of-the-box. Otherwise, while you can close incidents in Sentinel, they will not be closed in all the other portals. That is really important.

In addition, the watch list could be improved. Microsoft could develop some analytic templates based on these watch lists, for example.

And if you don't have any KQL knowledge, Sentinel is actually quite hard to use or to get the most out of.

I have been working with Microsoft Sentinel for approximately one year.

It's a stable solution.

My clients are looking to increase their usage of Sentinel. Every time I look, there is a new data connector, so it seems like it's a product that is constantly in development.

I haven't used their technical support.

The initial deployment, for me, is not really complex. It takes one hour or less. But to be able to use Sentinel to its full capabilities, you must definitely know something.

In terms of an implementation strategy, you need to really think ahead about who should be able to do this, and who should be able to do that, and respond to that, et cetera. A proof of concept would include dealing with the architecture, gathering initial data sources and/or automation, and then learning how to navigate in Sentinel. One person can do it.

My clients are enterprise-level companies and the solution requires maintenance. It includes updating analytics, importing, and creating new analytics. It depends on the company. If you have 100 employees, one employee might be enough to maintain things, but if you have 10,000 employees and 10,000 devices, you might need more employees.

No license is required to make use of Sentinel, but you need to buy products to get the data. In general, the price of those products is comparable to similar products.

My advice is to start out with a little bit of data and build on top of that. Don't enable too many data connectors in the beginning. Get familiar with the product, and remember to work with Sentinel every day. That's the only way the product gets better.

It comes with some out-of-the-box analytics, but to get the full and best usage out of it, you have to really keep developing it with hunting queries, analytics, et cetera. The visibility provided by the built-in analytics rules, what they detect, is rather good, but Microsoft Sentinel requires ongoing work. It helps automate routine tasks as well, but that's not something that comes "for free." It also requires ongoing work.

Threat intelligence is something that you must be more than just a novice in Sentinel to make use of.

Overall, I find Sentinel to be a really strong solution. Sentinel is where you can see the overall security status of your company. I really enjoy working with Microsoft Defender and the entire suite, combined with Microsoft Sentinel.
