Microsoft Sentinel Reviews

We have had various use cases depending on the needs of our customers.

It is a SaaS-based solution. It does not have any versions.

In traditional SIEM solutions, there is a lot of hardware, and there is a lot of maintenance around it. We require a lot of resources for administrative tasks, whereas with Microsoft Sentinel, we don't have to get into all those details straight away. We can concentrate on the use cases such as detection and start ingesting our logs, and right away, get insights from those logs. In addition, traditional SIEM solutions, such as Splunk, QRadar, LogRhythm, or ArcSight, do not support cloud-based logs much. This is where Microsoft Sentinel comes into the picture. Nowadays, everyone is moving to the cloud, and we need solutions like Sentinel to easily ingest logs and then get insights from those logs.

It has definitely helped to improve the security posture.

The in-built SOAR of Sentinel is valuable. Kusto Query Language is also valuable for the ease of writing queries and ease of getting insights from the logs. Schedule-based queries within Sentinel are also valuable. I found these three features most useful for my projects.

Microsoft Sentinel has many native connectors, which are plug-and-play connectors. You don't have to do any kind of analysis before starting. Taking Azure Cloud logs as an example, once you enable Sentinel and the connector, you start getting the logs straight away. You get a visualization within Sentinel through dashboards, which are called workbooks. So, right from day one, you can have security for Azure Cloud. If you have other clouds, such as AWS and GCP, even they can be included right away.

There is not much guidance on the in-built SOAR solution that uses Azure Logic Apps as a service. For people coming from traditional SIEM solutions, it is difficult to understand how SOAR works. Because the security teams are not from a programming or coding background, they cannot directly jump into SOAR. For Kusto Query Language within Sentinel, Microsoft provides a lot of documents and articles, and they also have a community, but when it comes to SOAR, other than a few open articles, there isn't much information. The documentation part of SOAR should be improved.

The dashboards can be improved. Creating dashboards is very easy, but the visualizations are not as good as Microsoft Power BI. People who are using Microsoft Power BI do not like Sentinel's dashboards.

I have been using this solution since October of 2019.

It is stable.

It is a SaaS-based solution. So, as end-users or customers, we don't have to think about scalability. 

Sentinel Contributor and Sentinel Responder are the primary roles of its users. Users with the Sentinel Contributor role can perform anything on Sentinel. The Sentinel Responder role is allocated to L1 and L2 monitoring teams. They actively monitor the Sentinel console for any triggered incidents and remediate those tickets.

In terms of the number of users, it is a typical SOC team, which depends on the number of incidents. We calculate the full-time employees based on how many alerts are being triggered per month. If 1,000 alerts are being triggered per month, we would need eight FTE to run 24/7 operations.

We definitely have plans to increase its usage. Microsoft is continuously improving this product, and we also have private access where we can see what features are being launched and provide input to them.

Microsoft Sentinel is a SaaS-based solution. They are improving it all the time. You can see new features every month and week. They are bringing more and more features based on customer feedback. That's one of the things that I liked the most about Microsoft Sentinel, which I did not see in other products.

I like their support. When you raise a ticket with Microsoft, you'll get a response within four hours or so. A support person is assigned who then directly reaches out to you on Teams to troubleshoot.

They send the ticket to the right team. They reach out and guide appropriately. They inform me that they are taking care of the issue, and if a meeting is required, they ask about a suitable time so that they can block the calendar. I have never encountered any issues with the support team where I had to escalate anything to someone else. I would rate them a nine out of ten.

I have worked with QRadar and NetIQ Sentinel. These traditional SIEM solutions are not equipped to effectively handle API integrations on the cloud. Nowadays, most organizations are on the cloud. For Microsoft-heavy or cloud-heavy environments, it is very easy to manage and very easy to ingest logs with Microsoft Sentinel.

It was straightforward. Deploying Sentinel doesn't take much time, but the initial design required for any solution takes time. Once you have planned the design, deployment involves using toggle buttons or bars.

In terms of the implementation strategy, being a cloud solution, not all customers are there in a single subscription. There could be various tenants and various subscriptions. We have to consider all the tenants and subscriptions and accordingly design and place Sentinel.

Ideally, it takes two to three months to onboard log sources, and for implementation, three to four resources are required.

We have definitely seen an ROI. In traditional SIEM solutions, we need to have people to maintain those servers and work on the upgrades, whereas when it comes to the SaaS-based solution, we don't need resources for these activities. We can leverage the same resources for Sentinel monitoring and building effective detection rules for threat hunting.

There are no additional costs other than the initial costs of Sentinel.

We didn't evaluate other solutions.

I would recommend this solution. Before implementing it, I will also suggest carefully designing it based on your requirements.

You have two options when it comes to ingesting the logs. If you aren’t bothered about the cost and you need the features, you can ingest all logs into Sentinel. If you are cost-conscious, you can ingest only the required logs into Sentinel.

I would rate it a seven out of ten.

We are developing our security signals for Microsoft Sentinel, so we are making a connector for Microsoft Sentinel. We try to use several features.

When using mobile devices, if there is an attacker or malware, the signal goes to the Microsoft Sentinel console from there. Our IT admin looks at those incidents.

The importance of that for our organization is because we are using our mobile devices for work. Mobile devices are not safe enough.

I focus on mobile devices while using Microsoft Sentinel. Mainly we want to expand our Identity performers. 

The signal correlation and dashboards features of Microsoft Sentinel are fantastic because it correlates the signal logs with other products. The customizable dashboards are also valuable.

Microsoft Sentinel's ability to correlate data from multiple sources and its detection capabilities are essential.

Microsoft Sentinel can be improved in terms of automation or connecting with security products so that it is easier to use for general IT admins.

I started using Microsoft Sentinel last June, so it has been about a year.

I was not using any other solutions for this specific task before Microsoft Sentinel. We ultimately chose Microsoft Sentinel because we have partnerships.

We have not yet seen a return on investment with Microsoft Sentinel. We expect to see a return on investment this year. 

We try to use the security incidents feature in Microsoft Sentinel, but I have not seen the actual incident yet. I could not find good use cases. My experience with the collaboration capabilities of Microsoft Sentinel is limited, as I am still getting used to it.

I would rate Microsoft Sentinel a seven out of ten. 

The usual use cases would be starting from scratch, implementing Sentinel for clients, onboarding log sources, building analytical use case rules, and supporting the platform for operations.

The main benefit is the ease of integration. Having a cloud-based SIEM means scalability. We also received very good support and documentation from the vendor.

All of the features are great. In fact, when they add new features they are always valuable and interesting. There are so many features on offer.

I really appreciate that it is very well documented.

I also use Defender 365, including Defender for Endpoint. It's easy to integrate with Sentinel. In two clicks we can integrate them together.

I have experience with Defender for Cloud. I'm actually getting into the Center for Cloud right now, so I'm just Learning about it. 

Sentinel enables us to ingest data from our entire ecosystem.

It's important to have data visibility for our security operations. Sentinel enables us to investigate the threats and respond from one place. That is very important for operations. We need to be able to easily look and have visibility over what's happening.

Sentinel enabled us to automate routine tasks. It helps us automate the handling of trivial tasks related to alerts. 

With the solution, we no longer have to look at multiple dashboards. I wouldn't say it has completely eliminated looking at different dashboards. As it stands right now, there are two dashboards that we will have to look at. One is Sentinel, and the other one is a ticketing system.

Compared to what's being used, it's saved us some time overall. The ease of use and the clear documentation are helpful in that regard. Someone who doesn't know how to use it can easily go in and find out.

When it comes to ingesting Azure native log sources, some of the log sources are specific to the subscription, and it is not always very clear. Sometimes, if the individual doesn't know what they are doing, they might enable it only on one subscription and not on everything that they need to monitor.

I've used the solution for two and a half years. 

I haven't experienced any stability issues. I've experienced 100% uptime. 

I've never seen it scale up or down. If necessary, it likely happens in the background. It's not visible to clients, however, I haven't noticed any issues. 

My experience with technical support is good. It was an excellent experience. They were very, very responsive to the questions that we had. If they were not able to answer on the spot, during the call, they took it back and discussed the issue with their team. Getting an answer was fairly fast. Overall, I've had a good experience with support and I can't complain.

I'd like them even more if I was able to request support on behalf of clients without having to actually access the client's Azure or having to identify the client's tenants. 

Positive

I've used Splunk, ArcSight, and QRadar. Sentinel is excellent compared to those solutions. It could always be easier, however, it's pretty much there.

I was involved in the solution's deployment. The cloud deployment takes five minutes and is very easy. The on-premise portion on the other hand, when I first did it a year and a half ago, was a little bit more complex since it involved a lot of customization. However, now it's more streamlined.

There is no maintenance necessary. It's a managed service. There's no patching of any sort. The on-premises components may require a little bit of maintenance every now and then if they need a patch or upgrade. If there are any changes in the environment they would have to be reflected in the configurations. 

I handled the implementation myself. 

I know the price, however, I don't know how it compares with other SIEM solutions. I don't have that visibility. I overheard not too long ago that Sentinel is on the expensive side. However, there are some capabilities that are fairly new that Sentinel offers to lower the cost. 

I'd rate the solution a nine out of ten. 

Our organization is a service company, therefore, we are proposing Microsoft Sentinel as an MSSP solution to our clients. Additionally, we are offering other solutions with Microsoft Sentinel. We have integrated Microsoft Sentinel with MISP, an open source intelligence trading platform, to create a deluxe solution. Furthermore, we use the five-year tool in conjunction with Microsoft Sentinel.

We pitched the solution for BFSI, healthcare, and ONG sectors.

The solution can be deployed based on the client's requirements.

Microsoft Sentinel provides visibility into threats by creating alerts, which will generate an instance and notify us. We can also view files and prioritize alerts using Microsoft Sentinel. Additionally, there is a tool with Sentinel that allows us to check alerts, which will help us identify false positives and false negatives, which is very beneficial for analysts.

Microsoft Sentinel helps us prioritize threats across our enterprise.

Microsoft Sentinel's ability to help us prioritize threats is a very important must-have feature for our organization.

Integrating Microsoft Sentinel with additional Microsoft solutions such as Microsoft Security Center is easy because we use a Microsoft agent. There is a default integration available with multiple connectors and we can use the agent to install data into Microsoft Sentinel.

The integrated solutions work natively together to deliver a coordinated detection and response across our environment. We use a playbook for the response process. We also integrated ServiceNow tools and Sentinel for ITSM. We are also designing the playbooks to meet our requirements.

Having the ability to integrate solutions with Microsoft Sentinel is an important feature.

Microsoft Sentinel provides comprehensive protection. 

Our organization has a strong partnership with Microsoft. Most of the services we receive are quite cost-effective. Microsoft provides market listings, allowing us to design our solution and place it on Microsoft's market listings, resulting in mutual benefits for both Microsoft and our organization.

We used Microsoft Defender for Cloud to get to the Azure security center for Sentinel. We wanted to work with a particular server but at the time the requirement was in order to use Defender we had to enable the solution across the subscription and not on one particular server.

Microsoft Sentinel enables us to ingest data from our entire system if we want.

Microsoft Sentinel enables us to investigate and respond to threats from one place. We can control everything from a single pane of glass.

Microsoft's built-in UEBA and threat intelligence capabilities play a major role in our security.

We can automate routine tasks, prioritize alerts using the playbook, and use the analytical rule's default settings when creating an alert. This helps to reduce false positives so that we only receive one alert for each issue.

Microsoft's XDR enabled us to avoid having to view multiple dashboards. We can integrate a variety of tools with Sentinel, allowing us to monitor all relevant information from a single screen.

The integration into one dashboard reduced our analytical work because it reduces the time required to review and respond to threats. 

The solution helped us prepare for potential threats proactively. Microsoft Sentinel helped our organization save money by preventing attacks. The solution helped reduce the threat detection time by up to 40 percent.

The data connectors that Microsoft Sentinel provides are easy to integrate when we work with a Microsoft agent.

The UI design for the investigation portion of Microsoft Sentinel is great.

The alerting of the queries works great and it is easy to develop a query around our requirements using Microsoft Sentinel.

The GUI functionality has room for improvement.

The playbook can sometimes be hefty and has room for improvement.

The troubleshooting has room for improvement.

I have been using the solution for three years.

The solution is stable.

The solution is scalable.

The technical support depends on if we have upgraded our support or not. The basic support has a wait time but the premium support is great.

Positive

We previously used IBM Security QRadar. The data connectors are more complicated and there are more configurations required with IBM Security QRadar compared to Microsoft Sentinel. The alerts are much better with Microsoft Sentinel.

The initial setup is straightforward.

The implementation is completed in-house with Microsoft documentation.

In comparison to other security solutions, Microsoft Sentinel offers a reasonable price for the features included.

I give the solution an eight out of ten.

The maintenance is completed by Microsoft.

I recommend Microsoft Sentinel to others.

Our customers primarily use the solution to monitor their infrastructure locally.  Some of our customers want to monitor logs to find some abnormal instances, so, they use Microsoft Sentinel to identify threats or identify what is happening in their infrastructure.

Microsoft Sentinel is easy to use compared to some third-party solutions, for example, if we want to get a log using a lot of the third-party solutions it is very difficult because we have to configure it. But in Microsoft Sentinel, if you want to get a log, you just click next, next, next, and see the log. It's straightforward to use the solution. Microsoft Sentinel is on the cloud, so we don't need to maintain a lot of the OS issues we have with other products. Sometimes SIEM has problems that require a lot of maintenance to resolve the OS issues and that takes a lot of time to deal with, but the Microsoft Sentinel benefit is you're on the Cloud. We don't have to spend time dealing with OS issues. We can use that time to focus on critical incidents.

The most valuable features in my experience are the UEBA, LDAP, the threat scheduler, and integration with third-party straight perform like the MISP.

The product can be improved by reducing the cost to use AI machine learning. In my experience in Taiwan, if you want to use Microsoft machine learning for Microsoft Sentinel, the cost is high. The high cost keeps customers from using the feature.

Currently, I think that the customized log can be improved because I check some documents, and Microsoft Sentinel can only customize some file logs. If some logs can be in a database or some user Syslog for all the events in Microsoft Sentinel to be supported. I can't choose to parse the log. I hope Microsoft Sentinel can support more and more different event types for customization. The solution ends up passing a lot of the logs.

I have been using Microsoft Sentinel for 13 months.

The solution is very stable.

The solution is easy to scale.

Technical support uses a ticket system. We just use the portal and I can open a ticket for them, and they will respond back to us. The technical support team is very good they solve a lot of the issues for us, or help us solve a lot of issues, but sometimes the issues can be more complicated and they cannot help us. If I submit a complicated ticket to technical support and they still don't know how to resolve it we are required to use premium support and that option comes with an additional fee. If you have less complicated issues free technical support can resolve the ticket but with more complex tickets you need to use the premium service.

Positive

The initial setup is very easy we just choose where to create, and then next, done, finished. Very easy. The deployment took less than five minutes and only required one person.

The implementation was completed in-house on my own. I just studied Microsoft documents and trained myself. If I still don't know something, I open a ticket to Microsoft to get some help.

The solution is expensive and there is a daily usage fee.

I give the solution an eight out of ten.

I am a third-party user of the solution, but if I were an outside user of Microsoft Sentinel, I really like it because they have a lot of the functions that others don't have. Things like the UEBA and intelligence from Microsoft. Microsoft has already studied a lot of threat intelligence, and they have the capability to help us detect what kind of content will match Microsoft intelligence. I like this and also has a lot of AI machine learning. This will help me to review or, learn easily. I hope this product will help me with a lot of things.

The solution states that it provides good visibility into threats by identifying vulnerabilities. I'm not clear on the vulnerability feature. I am not sure if most customers are familiar with the feature. I believe the feature is used to detect a lot of threats, but what kind of vulnerability? I am still not familiar with the feature.

I think because our enterprise has a lot of different Standard Operating Procedures it depends on the customer, for example, the solution helps detect ransomware, and that helps the organization prioritize dealing with the ransomware situation above other threats.

We have one customer that has implemented Microsoft Security E5. That means they also have Microsoft Defender 365. They use this to detect their infrastructure and their endpoints as well as if they have a SaaS platform they can monitor abnormal behavior.

I have integrated Microsoft Sentinel and Microsoft Defender 365, and they are very easy to integrate. They also have a correlate function and they have rules called Fusion. This Fusion function helps us investigate the correlation between the products.

Because my job is to help the customer integrate, I don't know how well the solutions work together to deliver detection and response for our customers. I am not involved once the solutions are deployed.

In Taiwan, we don't have customers that use Microsoft Defender for Cloud but I use it in my lab.

Some of our customers have additional solutions that are not Mircosoft. I have some customers, who have some data from the Microsoft device, from Windows and maybe events, and others that are not Microsoft products. The customers use their own on-premise, third-party products and buy their solutions. Hence, it is difficult to say if Microsoft Sentinel enables us to ingest data from the whole enterprise.

You can investigate the threats and respond from one place using Microsoft Sentinel. We should report correlation too. It's effortless to investigate responses in Microsoft Sentinel.

In Taiwan, we don't believe in automating routine tasks. There are a lot of things we still do manually and are not using the automated function of Microsoft Sentinel except to send mail.

With Microsoft Sentinel, we use one unified dashboard that is very easy.

We don't use the threat intelligence from Microsoft Sentinel because it is not public, so when a threat is detected that matches the Microsoft database threat intelligence, they only send us an alert, but they don't provide the content inside. Instead, we use open-source threat intelligence and integrated it into the solution.

Using Microsoft Sentinel has reduced the time spent per incident from three hours to one and a half to two hours.

The solution has not saved any money because it is still expensive. We have a large customer demand but all the vendors are as expensive as Microsoft Sentinel. I think they are very expensive. The solution has a daily usage charge.

Depending on the rule being used the solution can save us time in detecting incidents or threats. I can say we just use the default, sometimes it's very long and doesn't really take a lot of time. We get the result to tell me, "Oh. You have an incident happen." But I still don't know why Microsoft usually misses the threats. I still don't know why they design it like this, because I have had some instances in my past experience where the rule is if a threat is detected we must immediately alert first. Perhaps the detection module for Microsoft Sentinel is old. It starts to already alert us and that is a default rule. So, I still don't know why Microsoft Sentinel was created like this. I still don't understand. If you use a UEBA, to detect some threats in some abnormal behavior it's very fast, but if you use the scheduler to detect a lot, sometimes it takes a long time.

In my experience, everything is working and the solution doesn't have any bugs.

The solution is only released on the cloud on Azure. You can't deploy the solution on-premise.

Currently, I only deploy in a single environment. I don't have another environment because almost all our customers use a single environment. Perhaps in the future, they will add another cloud that will use Microsoft Sentinel. That is a very long time in the future. In my experience, the solution is used only in a single environment. We have two people in our organization that use the solution and four to five large customers.

Since Microsoft Sentinel is cloud-based it updates automatically and requires no maintenance from our end.

I think I'm more likely to use a single vendor over using a best-of-breed strategy because a single vendor, integrates together all of the things. I don't need to customize. Trend Micro doesn't understand Microsoft products, and Microsoft products, don't know Trend Micro products. If I choose to use a single solution that means they will handle all of those things. I don't need to use or take the time to customize some functions. I don't need to do that. I prefer to use a single vendor.

If a customer is already using a lot of Microsoft solutions I would recommend Microsoft Sentinel because it is very easy to integrate, but if a customer is using multiple different third-party security solutions I would not recommend Microsoft Sentinel because it will take more time to integrate it and check everything.

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. 

Positive

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.
