Microsoft Defender XDR Reviews

It has helped us identify a lot of loopholes within our environment and mitigate risk. It has improved user experience as well.

The visibility into threats provided by the solution is amazing. If you have Sentinel, you can integrate it with Microsoft 365 Defender. You can then access all of the logs at once with a code. You would be able to quickly analyze and react to any threat.

We are able to prioritize threats with this solution. Depending on the type of license you have, you will be able to access different capabilities. We place very high importance on prioritizing threats because the easiest way to get attacked is through the user or the endpoint. You must have multiple layers of security.

We use several Microsoft security products such as Sentinel, Defender for Office 365, and Microsoft Defender for Cloud Apps (Cloud App Security). Microsoft has the highest form of integration, so these solutions integrate in a straightforward manner. Once Microsoft Defender for Cloud Apps is unlocked, you can connect to third-party applications as well.

These solutions work natively together to deliver coordinated detection and response. The threat protection that these Microsoft security products provide is comprehensive and very effective.

We use Microsoft Defender for Cloud and make use of its bi-directional sync capabilities. It gives us access to reports and makes reporting much easier as well.

Microsoft Sentinel enables us to ingest data from our entire system. Data ingestion is very important to our security operations because it makes it easy for us to know if there are any vulnerabilities or threats. It flags it, and we can analyze it and also create a query, which brings to light threats. We can then mitigate the threat or attack breach on the device.

Sentinel enables us to investigate threats and respond holistically from one place. It makes life easier for us and helps us not to be caught unaware. There are many forms of alerts that notify you immediately of any threats. You can set up automations, which might even fix the issue or mitigate the issue immediately without the need for intervention. That is, you can create a rule to automatically fix a particular problem.

Sentinel captures a lot of logs, and you'll be able to create action plans through the application to directly handle particular threats. The integration has been done already, so automatically it will send a signal to the environment or to the solution you have integrated with to carry out a particular action.

The cost of Sentinel is on the higher side compared to that of other standalone solutions.

We can automate routine tasks and write scripts to carry out difficult tasks, which makes things easier for us.

This solution has helped us to save 60% to 70% of our time.

Microsoft 365 Defender provides one XDR dashboard, so we don't have to look at multiple dashboards. In the Import Center, all you need to do is to select the solutions that you want, and it will give you multiple options on different categories and different data. It's amazing and straightforward, and you won't need to open other tabs.

We have been able to prepare for potential threats before they hit and take corrective steps. We can immediately identify users or systems that have viruses or malware. We can also find scripts that have errors underneath them. We can discover each element from the history and delete it. It covers a lot of aspects, and the integration with Sentinel helps as well.

Because there's someone actually monitoring everything, when there is a threat or any form of abnormality, all they would need to do is to create a rule or a query to create a particular section and add the action that needs to be carried out. It's easy to get to reports as well. Overall, the solution has decreased our time to detection and our time to respond by 60% to 70%.

Microsoft tends to provide too many features, which makes the solution prone to bugs.

Also, 365 Defender needs to be more flexible during deployment. When it comes to causal admittance, at times it seems slow.

We have been using this solution for about three years.

The stability is okay. Microsoft has evolved a lot, so they tend to make sure that the solution is up to date and up to par with best practices in the environment. They add new features as well.

It's very scalable.

The level of support you get depends on the knowledge of the engineer who has picked up your ticket. I'd rate technical support at seven out of ten.

The initial deployment is straightforward as long as you meet the prerequisites. 
It doesn't really take a lot of time to deploy. All you need to do is to set up the policy, then assign the license to the users. Microsoft handles the maintenance of the solution.

Defender Plan 1 is tenant-wise, and Defender Plan 2 is per-user, which makes it more expensive. To have certain features, you would need to purchase the E5 license. For all of the capabilities that the tool provides, the price, though it can be high, is fair. 

I don't think having a single vendor's security suite is the best because once the threat actors are in through the surface, it's easy for them to penetrate. This is because they'll know all the cracks in that particular product. However, if you have another vendor protecting you as well with a different signature database that is separate, then the attackers have multiple walls that need to be cracked.

An average-sized organization can go for the Business Premium plan. Larger organizations can go with E5, which comes with the full functionalities of Microsoft 365 Defender. Overall, I'd give this solution a seven out of ten.

In our organization, we are mainly using it for email security and SharePoint security.

It has been great for us. Previously, we didn't have a solution to protect us, especially from malware, whereas now, we are getting protection up front, especially from the malware attacks coming through emails or endpoints.

It helps us to prioritize threats across our enterprise, which is very important. It has sorted many things.

We use Defender for Endpoint, and we also use Sentinel. In my organization, they are all integrated. Sentinel pulls the data from M365 Defender via connectors. The integration is very easy. There are no problems. These solutions work natively together to deliver coordinated detection and response across our environment, which is good. We rely a lot on Microsoft products. Together Defender for Endpoint and Sentinel give me a clear picture to defend against threats and investigate the threats.

Sentinel enables us to ingest data from our entire ecosystem. It's always good to get a centralized, holistic view of our security operations. We are using centralized Sentinel dashboards mainly to get all the threats and information in one place. It's good.

Microsoft security products provide comprehensive and deep threat protection. I'm pretty satisfied with that.

It has saved us time. It has saved more than 50% of our time. 

It has decreased our time to detect and time to respond. It has been helpful, and the time to detect is really fast. We don't have to do anything. We just have to rely on it. In terms of the time to respond, if something is under the radar or intelligence of Defender, the tool itself responds and gives us what happened. When it comes to something that is not on Defender's radar, Sentinel is generally where we go. So, it saved more than 50% time in terms of detection and response.

Email security and endpoint security are valuable.

It provides good visibility of Microsoft products but not for third-party products. It's a good product if we have Microsoft product lines to protect or defend, but it lags when it comes to a mixed environment or non-Microsoft products. The Defender agent itself is more compatible with Windows 10 and Windows 11. Other than these two lines, there are so many compatibility issues. Security is not only about Microsoft. The core technical aspects of it are quite good, but it would be good if they can better support non-Microsoft solutions in terms of putting the agents directly into VMware and other virtualization solutions. There should be more emphasis on RHEL and other operating systems that we use, other than Windows, in the server category.

On the Defender side, for custom detection queries, KQL and the dashboard are not that great, but we are not doing automation directly from the Defender side. We leave Defender intelligence as it is, and we collect everything from Defender to Sentinel and handle the response from the Sentinel side. So, all our automation is happening through Sentinel only. We don't have any extra customization on top of Defender.

The maturity of the portal or dashboard is missing. The dashboard is something that Microsoft is changing every month, and we are seriously not liking it. As a management person, I am not bothered about it, but my team is suffering because there are many versions. You are working on a version and then a new version comes and then the preview toggle button comes. Now, they are combining all the parts into a single console. It confuses technical teams a lot. I'm not happy with their approach or experiments when it comes to the Defender portal. They shouldn't change it again and again.

The SOAR side of Sentinel is zero. If any subscriber subscribes to Azure Sentinel, SOAR is zero. Microsoft says that Sentinel is a SOAR solution, but I don't agree because they are only exposing the existing Azure automation engine towards Sentinel. My automation ask is that when there are already so many detection rules and connectors, why is the SOAR capability not in-built? Why can't they make the Azure functions behind it available in a template form and let us modify and use them? It will save my team's time in preparing the automation of the response. If my team has to create the logic, they have to invest a lot of time.

Their support needs to be improved. I'm not happy with their support.

I have been using this solution for more than a year.

For stability, the product must be mature enough. It should not keep on changing every month.

It's scalable. Target points are in my capacity, and I can scale it without any problems. There is no limit to the agents for Defender, but on the server side, Microsoft would have the answer. 

Location-wise, we are spread in five locations within one country, and department-wise, we have around 11 departments.

Their support is bad. They weren't at all able to solve my problems. They buy the time but never get back. I have to follow up with them again and again. They just take the logs and sleep on them. I'm not happy with their support. I would rate them one out of ten.

Negative

We were using another solution. Our organization at the time was too much dependent on the on-premises infrastructure. We were using Symantec, but it was a very quick shift within one quarter or two toward the cloud products and services. We are now heavily reliant on Microsoft Cloud products. We have the Azure environment and a lot of cloud applications, and we have shifted to M365 and Sentinel.

We have a hybrid deployment. Within the cloud, it's straightforward, and when it comes to the target points, it's doable. 

Our biggest challenge was removing the old Symantec signatures from the registries, devices, and servers. That was what we mainly struggled with a lot. Otherwise, deployment was going very smoothly. We had around 46 virtual machines or servers. The problem was that the MDATP agent was not ready to protect them. We struggled a lot there. We went to Microsoft, and Microsoft said to go back to Symantec, and when we went to Symantec, they asked us to go back to Microsoft. That took a long time for us. Everything else was smooth. When the target point is Windows, it's very smooth.

It took around 20 to 25 working days. In terms of the staff, other than the infrastructure team, there were five people including me.

In terms of maintenance, we have to just work on the detection rules and nothing else. There is no other maintenance. It's a complete cloud solution.

It's quite hard to measure the money saved from using this solution because we have not got any attacks that have resulted in any kind of ransom or monetary loss. It's defending us, and as of now, as per my report, there are no financial losses due to any attacks.

Microsoft's pricing differs geographically. We are based in India, and we have India-based licenses. Money-wise, it varies from product to product or OEM to OEM. We pay less for some, and we pay more for some. 

Microsoft has a lot of CSPs, indirect partners, and direct partners to deal with customers. There is so much difference in the price, which is something we are a little confused about. For Defender, they have Endpoint Plan 1 and Endpoint Plan 2, but I don't know on what basis they have classified Endpoint Plan 1 and Plan 2, but it has given me enough pain to pick and design Endpoint Plan 1 or Endpoint Plan 2 for my organization. In fact, we are still struggling with it. Too many SKUs are confusing. There should not be too many SKUs, and they shouldn't charge for every new feature.

We evaluated Okta products and QRadar.

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 a single vendor security suite is always better. It's simple. It saves the time to detect and respond and administer.

This product is best if you have mostly Microsoft solutions in your ecosystem. If more than 20% of your solutions are third-party solutions, you can also look at and compare other products.

Sentinel enables us to investigate threats from one place, but when it comes to response, we have to put a lot of effort into it because Microsoft is not giving anything ready-made on the SOAR side. We have to put a lot of effort into orchestration and automation. The SIEM of it in terms of the collection of security events and information is wonderful, but when it comes to the SOAR capabilities, there is nothing in-built. They are just the analytical rules for the detection purpose, not for the response. The response is something we have to sit and design. So, the defending capabilities of Defender are good. It has some intelligence, but on the response side, Sentinel is blank. We have to start from scratch. It's a circle, and we have to keep on evolving. When comparing the cost, I am not that exposed to other products' costs, but as per my understanding, the cost of Sentinel is a little bit on the higher side because Microsoft generally charges on a log ingestion basis. It also depends on the amount of log data we are ingesting in Sentinel.

Its threat intelligence hasn't helped to prepare us for potential threats before they hit and to take proactive steps because it depends on the type of attack, the type of payload exploits, and other things. However, as per my previous report, in the last six months especially, there have been quite impressive preventive features, especially related to the process memory injection attacks or attacks coming from emails and links. It's very good for those.

Overall, I would rate this solution a seven out of ten.

We implement it on client endpoints and server endpoints. We also integrate it with Microsoft Entra ID for the identity part because the security part of Microsoft Defender is completely correlated to user activity.

Microsoft Defender XDR is important for the mitigation of threats, visibility of vulnerabilities, and identification of issues within the environment. It has been a leader in the market for consecutive years.

We have a single pane of glass for servers, endpoints, and mobile devices. It makes it very easy to identify which devices are at risk when you go to the vulnerability part. There are also recommendations. Especially for me, these recommendations are gold. You see exactly what you need. Microsoft Defender XDR is completely different from your antivirus solution. It detects based not only on signatures but also on the policies, so you are forced to harden your servers or client endpoints, which makes a much stronger solution.

Being a Microsoft solution, it integrates well with other Microsoft systems. The majority of the systems are Microsoft-based. This integration comes without the need to install a client on the local machine. It makes the life of the operators and whoever implements it way easier.

Microsoft has a range of Defender products. There is Defender XDR, Defender for Endpoint for clients and servers, and Defender for Office 365 which protects mailboxes, SharePoint, and OneDrive. Then you have Defender for Identity, which is integrated with Defender XDR. You also have Defender for Cloud Apps that is connected to Defender XDR. When integrated, you can get sources of threats, for example, from Defender for Identity connected directly on the endpoint. Defender for XDR protects the endpoint devices against ransomware and different threats. We need to see more holistically at all the Defender solutions instead of isolating them. There is an element of correlation of identity. For me, nowadays, it is much more important to protect the identity than the endpoint device itself because the majority of the vectors are coming from identity attacks. They are more than the viruses attacking the endpoints.

I do not have much experience with Linux as such. I am very focused on Microsoft solutions. I never focused on Linux, but I have worked with my peers, for example, on projects to enroll Linux devices. We needed to prepare simple scripts or puppet scripts to automate the process of pushing policies and automate the update of the antivirus. It is trickier. It is more complex to manage because of the nature of Linux itself. It is not as straightforward or integrated as Microsoft solutions, such as Microsoft Windows 11 or Windows Server, but Microsoft Defender still covers everything. There are some limitations regarding Linux servers and endpoints because you need to have the version of Linux that is supported by Defender, but at the same time, with whatever is supported, Microsoft Defender does the job. Linux and Windows operating systems work in different ways, and the way that antivirus interacts with the operating system is completely different. There is role-based access control in Windows. You have local administrators and domain administrators. On Azure, you define roles for users to access certain environments. On Linux, you have the root user, and as a core front operation system embedded in it, you do not have the least privileged access management solution. This comes with a price because you need to control much better to whom you give access. SSH keys, for example, are very important to be protected, which is a different protocol than the Remote Desktop Protocol (RDP). You need to protect Linux servers in different ways, which is very different from Windows. Defender or Defender XDR extends the protection, especially when you need to connect with Azure Ark, which is part of Microsoft services.

Microsoft Defender XDR has consolidated security solutions. Previously, you had an antivirus, and you had a different type of endpoint protection for servers, and then you had a web content filtering solution, which is part of Microsoft Defender XDR. It consolidates all the extra products that you require, but it does not give all the elements. It is not a firewall. It is not a web application firewall (WAF). It does not give you everything required as a security solution, but as an extended detection and response system, it gives a lot of leeway for you to meet your security objectives. If we compare it with other products, Defender XDR is much more complete than the competition.

The integration, visibility, vulnerability management, and device identification are valuable. You can automatically deploy the clients depending on how you are implementing the solution. 

The web filtering solution needs to be improved because currently, it is very simple. It is very important.

Integrations with Linux should be done in a better way. With the AI world and the security part, things are going to be much simpler and easier to set up, configure, deploy, and maintain. I am looking forward to new releases of Microsoft Defender XDR to have better integrations, but the web filtering solution is the main pain point.

I have been working with Microsoft Defender since it was released. It has been about four years. I started working with it when it was not even called Defender. It was Advanced Threat Protection. It then changed to Defender for Endpoints and then to Defender XDR.

I have not experienced many bugs or issues. Sometimes, you have delays in the response, but that is due to connectivity issues. It is a cloud-based solution, so you cannot expect to have a real-time response, but this can be improved by Microsoft. I know that they are trying to improve. I would rate it a nine out of ten for stability.

It is ultra-scalable. I would rate it a ten out of ten for scalability. 

I love Microsoft, but due to its growth, the overall support quality has decreased a lot. My recent experience with support was not that good. For the Defender part, it was not that bad. I would rate their support a six out of ten. Their response time and knowledge could be better.

Neutral

I work with Trend Micro. I work with Kaspersky. Trend Micro has its own cloud-based solution similar to Microsoft Defender XDR, but it is not the same. It has some problems. It is not as effective as Microsoft Defender XDR. Especially whenever it comes to vulnerabilities and recommendations, Microsoft Defender XDR is amazing because of its integration with Microsoft operating systems. Microsoft is much ahead of the competition.

I would never touch Kaspersky again. It is not because it is a bad product. It has been a very good product for several years, but because of the Russia and Ukraine war, it has become a prohibitive product at least in Malta to use. A lot of customers moved from Kaspersky immediately to different products. The majority of them went to Microsoft Defender XDR, especially because it also comes integrated with some products. Microsoft is bundling its own products, and Microsoft Defender XDR is very attractive to implement as a cloud solution. It is a no-brainer for the customer. That is where Microsoft has an advantage over Trend Micro, Kaspersky, and other vendors.

With Cloud servers, it is easy and very straightforward. You can almost do it automated, but in a hybrid environment, you have the element of the on-prem servers, which becomes a little bit more complex. You also have the element of Azure that simplifies the deployment process.

It can be difficult to deploy in the beginning because you need to consider different products and elements, but the deployment is the simplest part of the onboarding process. The configuration process is much more difficult, especially because on servers, you need to deploy group policy objects (GPOs) and set all the policy options to protect from the vulnerabilities. You need to configure the antivirus to protect from exploits. There are so many features and configuration possibilities that it becomes more complex to implement on server endpoints. On the client side, it is easy, especially when you implement Defender through Intune, which is the mobile device management solution of Microsoft. With a platform like Intune, it becomes easy because you have policies that assist you already out of the box, such as security baseline policies. With Intune, it is much easier to set a policy. It is way less complex to implement. When you have a hybrid environment with endpoints joined on a local active directory, the complexity increases because you need to deploy GPOs as well if you do not have Intune involved. It is complex to implement.

The deployment takes a few weeks, but it also depends on the size of the customer. If you have just Windows 11 client endpoints, it is easier to implement. Client endpoints are easy to implement because you do not need to test that much. You configure the policies. The policies are all known because of our experience. When it comes to servers, it depends on the server's workload. It depends on what type of service you have installed on the server side. If it is the IIS web server, you need to test certain policies that can block that service. You cannot simply go and implement the best practices of the policies because then you are going to make the server unusable. You are going to generate downtime, which is not ideal and also not the objective, so you need to be very knowledgeable on the infrastructure side and the security side of all applications. You need to study. You need to create a test environment and start implementing server by server. You require details, and it is complex to implement because of this reason.

I am currently doing an implementation for a company with 300 people, and it would take around two months to implement because of the number of servers and endpoints. You need to go into each and every device and analyze the environment. It takes a while. In smaller companies, it is very quick. Within a week or two, you can manage to implement it.

In terms of maintenance, there is no maintenance of the product, but there is maintenance of the environment. Microsoft releases frequent recommendations, and they detect new vulnerabilities very frequently, which requires constant maintenance of policies.

I usually allocate two people. There is one person more focused on the client endpoints, and the other one is more focused on the servers because of his expertise. We split the roles and responsibilities within the team.

It has not saved us costs, but we have invested in a proper solution. We have a better return on investment. We now have better visibility. We are investing in a product that gives what we need instead of a product that does not fulfill our requirements and our customers' requirements.

As a service provider, it is very hard to calculate an ROI. For customers, it is more of a return on value rather than a return on investment. If you have not been under any threat after implementing the solution, it provides the value you need. This is my point of view on security because there is no perfect solution, but there is a solution that works better than the others where you have much more control. With Microsoft Defender XDR, in my experience, we have managed to give that to our customers. Our customers are satisfied with the product, and none of them have replaced or changed Microsoft Defender XDR.

There is the cost of the license, and there is the cost of implementation services. Only by enabling a license for your user, all the features are not going to be enabled and the policies are not going to be configured. It does not work like this. You need specialized people to implement, monitor, and maintain the systems. It comes as a package.

I would rate Microsoft Defender XDR a seven out of ten for pricing. It is costly, especially on the cloud part. There is also Defender for Cloud, which is part of Microsoft Defender XDR. It is 15 dollars per server per month. It is worth it, but it can be costly. It depends on the company's size. That is the big issue.

If you have a company with ten employees and ten servers because you have your own infrastructure hosted within virtual machines, you need to protect ten client endpoints. It is cheap if you get a business premium license. It costs around 17 euros per user. To protect the servers, you need to pay an extra 14 euros per server per month. For ten servers, it is 140 euros per month. Per year, it is around 1600 euros. Small companies or companies with a small budget would not go for it because they do not want to invest in IT. They do not see this value. In my opinion, big companies can justify this cost.

In the countryside of Malta, it is tricky to sell the solution. I have to give them all the advantages. I always have a test environment, so I show them how it works, how the automated detection works, how it behaves, and how it acts on the threats. I give them an overview, and they get amazed. When it comes to the pricing, they get a little bit scared, but ultimately, they go because they see value in it. Everything depends on the value that a product gives and how you sell a product as a solution provider. An XDR solution provides value because it protects your assets. Your data is your major asset. If you do not have it protected, you can get hacked or have a ransomware attack. Companies are now starting to understand the importance of it, and they are starting to invest more. It is still a long way for us to have the mindset where they say that it does not matter how much it costs, we need to invest in security.

I would recommend Microsoft Defender XDR. It is the best solution in the market.

For me, Microsoft Defender brought a career change. It made me go deeper into the security products. Previously, I was more of an infrastructure guy. I was more focused on on-prem and Windows servers, but then I moved away from infrastructure. I work for a data center company, and I am a presales solutions architect designing solutions for financial companies, banks, and gaming companies or companies with online casinos.

A lot of people did not like Microsoft Defender because Microsoft was not known as a security company, but Microsoft has been investing billions of dollars every year in security, and now, they provide cutting-edge technology, especially with AI.

I have been following Microsoft, and I go to Microsoft events. There is a new product called Security Copilot that is going to be completely connected to Defender XDR. It will give much faster feedback and response to threats by issuing reports. Today, a security analyst takes four to five hours to prepare a report. With Microsoft Security Copilot and Defender, it is going to change massively. Within five to ten minutes, you can prepare a report with the Security Copilot solution. It is going to be released very soon, and I am looking forward to it.

Overall, I would rate Microsoft Defender XDR a ten out of ten.

We provide services to medium-sized businesses in the banking and administrative sectors. We are also using Microsoft Sentinel and Defender for 365. 

Defender helps our clients protect against any threats from outside the organization. Defender XDR helps our clients save about 25 percent by offloading some on-prem functions to the cloud. It also saves time because the cloud interface is manageable, and we can investigate incidents quickly. It's easy to create reports and share information with other teams. 

I like Defender XDR's threat detection and prevention capabilities. Defender's built-in identity and access management features are critical. The solution's coverage extends beyond Microsoft software. Defender is easy to use. It has a nice console, and everything is all in one place. 

The console is missing some features that would be helpful for a managed services provider, like device and user management. 

I have used Defender XDR for the last two years. 

I rate Defender XDR nine out of 10. 

I rate Defender XDR eight out of 10 for scalability. 

I rate Microsoft support nine out of 10. 

Positive

Some aspects of the deployment were not straightforward. It was moderately complex. I enabled all the connections and onboarding process, then implemented a basic set of configurations. It took about seven to 10 days to deploy. 

My clients have seen an ROI from using Defender XDR.

Defender XDR is reasonably priced but may be less affordable in certain countries. For example, it might be expensive for some customers in India. 

I rate Defender XDR eight out of 10. I would recommend Defender XDR. It's a fast solution, and it's easy to train people to use Defender. 

Defender XDR is a solution that protects your enterprise systems and devices.

Defender XDR has helped a lot in terms of capturing all kinds of activities happening on the endpoints where it is. If you want to know what happened at a point in time, you can go to the history and search everything. This helps you investigate exactly what happened if you have a security breach. It doesn't take much time, but I don't have anything to compare it to because Defender is the only XDR we've used. 

Defender XDR has a feature called the timeline that lets you track all activities. It helps a lot with investigations. Microsoft has many identity management features and products that complement each other.

It covers the weaknesses and vulnerabilities of non-Microsoft solutions, but it will not help you to do the remediation. You need another third-party tool to do the remediation. 

Defender protects against advanced attacks like ransomware or email phishing. The protection Defender provides is excellent. It's a great product for preventing attacks and reducing risks for organizations. 

There are a few technical issues with Defender XDR that can be improved. Sometimes, the endpoint devices are not reporting properly to the Defender 365 portal. When you're getting all the information from the Microsoft portal, the devices are sometimes not in sync. We have hundreds of endpoint devices, some needing to be onboarded again. 

I have used Defender XDR for three years.

I rate Microsoft support nine out of ten. It's excellent. 

Positive

We did a POC for a McAfee product. There weren't many differences, but Microsoft Defender was included with our E5 license. The major difference is that we saved money by not purchasing another product. 

Defender XDR is a cloud-based solution. You can access it and see all the information you need inside the Microsoft portal. 

Defender XDR is not expensive. It's average compared to other products. 

I can get Defender bundled with the E5 package. We had considered replacing it, but after evaluating some competing products, we decided there was no significant difference between the third-party products and Defender. 

I rate Microsoft Defender XDR eight out of ten. I think there is room for improvement in terms of its coverage of non-Microsoft technologies. 

Defender XDR can replace multiple security products. It covers everything, including phishing protection, network security, device security, applications, etc. 

The solution has reduced time spent on manual tasks because almost everything is automated. You don't have to do anything. If something happens, you'll get a notification, and it will instantly run the playbook for the incident. For example, a phishing email might take an hour to investigate manually. If you have Defender, you will have all the information you need on the incident page. It's all there, so you can investigate the incident in around 5 to 10 minutes.

Adopting Defender cuts costs. While the solution is a little pricey, you only need two products—XDR and Sentinel—so you don't need to add other security products. You only need to use the Microsoft security stack. 

The advantage Microsoft Defender XDR has over other XDRs in the market is that it's easy to use. You can quickly differentiate between alerts, incidents, devices, software, etc. It's easier to investigate an incident, and you have so many options. You can automate investigations and use playbooks. There's also the live response session, which is something you can't find in any other XDR. 

The identity protection is excellent. It uses some rules, including some built-in rules from Microsoft itself. It identifies risky users and differentiates between a user who is trying to sign in and isn't the actual user. Identity and access management is a valuable component of Defender.

Defender covers non-Microsoft technologies if you're using the full Microsoft stack with Sentinel and Defender. You can ingest logs from other solutions, like Palo Alto and Fortinet firewalls. 

It stops advanced attacks like ransomware and phishing in real time and prevents them from entering your environment. There's a feature called Security Advisory that shows you all the latest threats and vulnerabilities in the market so that you can make rules for them. It helps you understand them more. 

With Sentinel and Microsoft Lighthouse, you can use multi-tenant access. It allows you to connect multiple tenants to one tenant, which you can use to monitor everything from there. Before we had Microsoft Defender, we had to go to each tenant, log n from your account, and investigate the incident if it's there. Lighthouse has one page with all the alerts, and they're all connected together. You can investigate every alert from one page.

The design of the user interface could use some work. Sometimes it's hard to find the exact information you need.

I rate Microsoft Defender XDR 7 out of 10 for stability. There are some performance issues maybe 5% of the time. 

I rate Microsoft Defender XDR 9 out of 10. It's easy to scale. 

I rate Microsoft support 8 out of 10. They answer quickly. If you open a ticket, they will respond immediately. You can chat with them or schedule a call. 

Positive

The setup is straightforward. You only need to buy the product and onboard every device. It's like a script for Microsoft Intune. The process takes a couple of days for a small company, but a larger business may require three or four days. 

Defender XDR is fairly priced. 

I rate Microsoft XDR Defender 8 out of 10. I recommend giving the product a try. If it doesn't work for you, try something else until you find a suitable product. There might be other solutions that are a better fit. It's good for my case, but it might not be right for everyone. 

The product replaced Sophos, a third-party product we used, helping us save money equal to its yearly subscription. The product saves us time. We do not have to interfere. It just keeps running.

Considering we haven't encountered any technical problems since we started using it. It is working as intended. It has great stability.

I don't know if that is Defender's feature, but more active monitoring for data breaches would be beneficial. There could be a way to proactively monitor unusual activity versus just depending on viruses and malware. If the traffic seems unusual, it could detect anomalies and update us. It would help us stop malware attacks ahead of time.

I have been using Microsoft Defender XDR since 2015.

We never encountered stability issues.

Whenever we add a license, it automatically sets the account for a new user.

The initial setup process was fine and similar to Office 365. We had to get our email server lifted externally from the premises to the cloud. It is easy to use once all applications are deployed.

Microsoft Defender XDR is already included in our Office 365 licensing. It is better because we're saving money by using it.

The product was included with the Office 365 licensing that we had. So, we decided to try it out. Before that, we were using Sophos.

I haven't run into that particular instance where the security features have extended beyond Microsoft technologies. The only products we use outside of Microsoft are proprietary lockdown applications, and it's not really an issue there.

During staff training, we've been using Intune to detect phishing attempts. It hasn't detected anything in that aspect. However, it has the ability to check for malicious attacks preemptively.

I rate it a ten out of ten.

I'm a deployment engineer for Microsoft products, and we work with multiple SMEs. Customers adopting Microsoft products want the same features they had in their third-party solutions. We look at their requirements and the types of features they need. We determine the security mechanism that best addresses their vulnerabilities. We might suggest Defender for Identity,  Defender for Endpoint, 365 Defender, and Defender for Cloud Apps. In addition to those security solutions, we offer device management. We provide everything.

Defender improves our security operations. I've had chances to collaborate with our SOC team. Our customers face many random attacks they don't know how to prevent, and the SOC team handles them remotely. The security engineers can investigate the incident or use the information from the customer's environment to offer a recommendation. If the customer doesn't have the detection mechanism, we can recommend a product or find a solution for them. 

The solution can help customers save money because we can bundle it with all the other Microsoft solutions, like email and Defender for endpoint, identity, and cloud apps. Most of our customers use Windows 10 devices and Microsoft Active Directory, so everything is on the same page. Defender can save time by automating investigation and response. We don't need to spend much time because it'll automatically take action in many cases. 

The best feature is threat hunting. There are a lot of other features I like, such as the alert mechanism. The chain alert mechanism has a huge impact. It combines all the alerts into one incident and automatically correlates them with AI. 

Defender has integrated identity access management, and you can add DLP features through a separate solution called Microsoft Purview. Within the cloud, we can create access policies based on each user's risk. It's integrated with Azure AD and on-prem Active Directory, so all the user identities can be managed in a single portal.

We use the multi-tenant management capability, so we can cover customers that have multiple regions. We can easily investigate across tenants based on severity. For high-priority alerts, we start from scratch and ignore what's happening on the endpoints or emails. We isolate the device and ensure that nothing will be released from it. Next, we check this device and some more details.

There is no common area where we can manage all the policies for the EDR, third-party solutions, devices, servers, Windows, Mac, etc., but it's on the roadmap, and we were waiting for that feature. 

I have used 365 Defender for about four years.

365 Defender is stable. There is no downtime. Still, Microsoft is constantly rolling out features, so there are sometimes bugs after new releases. Our customer experience team is collaborating with Microsoft and sharing feedback with them. 

365 Defender is scalable 

I rate Microsoft support nine out of 10. The support depends on the product and the customer's issues. 

Positive

I work with customers coming to Microsoft from other third-party products, so I try to understand what the product does and suggest a solution. The names are different, but all the technology is the same.

Deploying Microsoft Defender isn't complex if you have experience. The deployment depends on the number of users, apps, and the client's requirements. If the client wants to implement XDR, it takes about a month to achieve full functionality.  Endpoint protection takes around five to ten days. It's a cloud product, so it doesn't require any maintenance. 

Defender XDR is agentless, so you don't need to install an agent anywhere. It's a cost-effective option.

I rate Microsoft 365 Defender nine out of 10. We recommend it to our customers. 

We use 365 Defender to manage organization-level devices and vendor security compliance. We are a retail-focused organization that offers cloud services through Azure, GCP, and AWS, but we manage all the security through 365 Defender. Some of our users are based in other countries, and everything is centralized. We operate in multiple regions. 

We can easily track any other malicious activities or additional applications that will prevent it. We can get it here. It will be a helpful tool once we create policies for DLP and third-party programs. 

365 Defender stops the lateral movement of advanced attacks. It prevents something that happens on the device level from affecting us on the organization level. The solution enables us to track all the details, like the IPs and the device types. 

365 Defender helps us deal with unknown threats by creating custom policies, which enable us to block access by specific unknown sources and unsafe links. 365 Defender has multi-tenant capabilities, and we have multiple tenants, but I'm only involved in the retail part, so I don't have authority over other tenants. 

We were able to discontinue some of our other security products when we implemented 365 Defender, but there are some exceptions. We can use non-Microsoft solutions when the customer requires it. Mostly, we use cloud solutions. We've saved some costs on the security side at the organizational level by reducing equipment costs. Using 365 Defender's automation capabilities, we can cut our vulnerability management time by about 40-50 percent. 

I like 365 Defender's advanced threat hunting. The dashboard is user-friendly with templates for site policies, etc. The most important use case is evaluating the risk links and applications. 

The cost can be high if you want to build custom license packages. Another area for improvement is the policies. In Azure, we need to implement policies in JSON format, but in 365 Defender 365, it would be helpful to use a different format so we can customize the platform.

I have used 365 Defender for more than two years. 

365 Defender can have some performance issues during enrollment. It can take a while at times, but sometimes it's duplicated immediately. That's an issue with some other cloud-based programs like Intune and Azure products. 

I rate Microsoft 365 Defender support nine out of 10. Their support representatives provide solutions based on priorities. They prefer to follow the proper SLA part. 

Positive

The deployment is quick, straightforward, and involves only two people. 

Sometimes 365 Defender is expensive, but it can be moderate, depending on the organization's size and the license type. We're satisfied with the cost because it gives us a product that protects our entire environment with DLP. To compromise some cost, of course, we are to complete the most secure environment. 

I rate 365 Defender nine out of 10. 

We're using it for our email filtering to check incoming emails and URLs. We're also using it for vulnerability management to see the status of our assets that are registered on the system. We also check it to see what kinds of threats and campaigns are currently being launched via emails.

It provides us with better insight into what's going on across our platform. It has also given us a very easy way to respond when threats or alerts come through. And when looking for someone in particular, it helps with that. It hugely improved our insight into what's going on inside the company's premises and environments.

365 Defender also helps find high-value alerts, but we haven't used it for complete automation. It has some automation features where it can try to block or quarantine things, but beyond the default automation configuration, we haven't explored deeper into using automation. The default settings work well.

And while we've always used one or two dashboards, this system has made it easier to have a quick overview on a single platform.

In addition, the threat intelligence helps prepare you for potential threats, to a certain limit, because it gives you insights into where your shortcomings are, your vulnerabilities. It also gives you some security recommendations to make improvements.

And the solution has decreased our time to respond because on high alerts you can get a quick response. The system will notify you very quickly if it detects something at a certain thread level or a custom threat level that you set.

Microsoft 365 Defender has a very great interface to help protect registered devices when it comes to web protection, which is very handy.

We also use the alert systems often. It's a great threat intelligence source for us, providing alerts for things it detects on the network and on the machines. We've used it often when there is a potential incident to see what was done on a computer. That works quite nicely because you can see everything that the user has done, including websites accessed, et cetera. And if something was on the machine, we can see what it was trying to do.

I use the alert system on a daily basis. It gives you a very good analysis of where something was found, which employee or which device. And it often gives you a good history on that. The alerts help me to monitor and check what is going on. That's a very valuable system to have.

We've also tried the attack simulation, which sends out phishing emails internally as a test to see how the users respond. We get feedback and use the training simulation as a result. We've only done that once, and it's something we want to work on a little more.

In addition, we're using the assets on the system as well as the inventory functionality. It checks all the machines to see what software is installed on them.

We've used a lot of the features on the cloud, although not everything to its full potential, but we've used 70 to 80 percent of all the features on the cloud.

In the beginning, it's difficult to navigate the system because it is quite large. Just trying to find your way and understand how the system works can be hard. After spending quite a lot of time searching it's a lot easier, but I wish it were a bit more user-friendly when you're trying to find things.

The information it provides is great, but for a newcomer, it is quite tedious and takes a long time to load. Here in South Africa, when you click, oftentimes you have to wait quite some time before you get to the next page. It's not necessarily internet-related. I think it's just that the service is a bit slow.

Also, while the solution does help to prioritize threats, unfortunately, it doesn't do so for the entire environment. The reason is that it only supports full integration from Windows 10 and up. It provides you certain information from your server environment, but when you start going with legacy services, it is a bit lacking.

Another issue that is sometimes a headache is that they constantly make changes. Things will be merged, they will get different names, or be moved around. Things will be added and other things go somewhere else. They do a lot of development to make the product better, but it's very frustrating having to search for stuff after they've moved it, because you don't always know that they have moved things. They might have little banners, but if you're just working and don't read them, you don't know where things have gone. 

I would also really like to see better integration with the server platforms for managing your server environment. That's something it currently doesn't do. For all the server environments, you either need to make use of group policies or SCCM to manage that independently. It can provide you information on the system, but it doesn't have control over your server line.

Also, I make use of 365 Defender on a business level and on a personal level. On the personal level, there is a lot less functionality. Something that would be very nice is that, for the level you are on, you would only see the product you are subscribed to. For instance, if you log on via the business, you have all your action areas, anything you can do and see, on the left. Because you're using it at a corporate level, you can see and do everything. On the personal level, or in a small business where you're only using some of the features, you still have all the same options, but when you click on them, it tells you that you need to upgrade or subscribe. They should only show you what you have access to, and not all the tabs and then say, "You need to subscribe to get access to this." It just clutters the whole area.

We have been using Microsoft 365 Defender for about two years.

Overall, it has 95 percent stability. We don't have any issues with it. It works well. Microsoft does provide frequent information when there are issues or delays. But the stability is very good.

We're still learning a lot about its capabilities. It's more capable than what we use it for. That is due to a restriction on our resources and availability to get to know the system even better.

We have contacted Microsoft tech support multiple times. They are quick to respond to the original request. Sometimes I have been quite surprised because they have replied within 15 minutes. Some of the questions we had were resolved quickly, on the order of 60 minutes. I had one that took almost two years to get resolved. But in general, they are quick to respond. Their support is very good and quick.

Positive

Before 365 Defender, we made use of Avast as our antivirus, which had its own web console. For malware protection, we used an on-prem Cisco IronPort system that was scanning all our emails. And most of our SIEM logging information was done manually. We had much less insight into what was going on in the company.

Because it was a new solution for us, we had a company that works with Microsoft assist us, to make sure that all the configurations were standard. But since then, we've maintained most of it ourselves. On our side there were no more than five people involved.

It's a very expensive product, but for any threat it has definitely stopped or protected us from, in that sense, it has saved money and time, by preventing things that could have happened. But is it affordable? No, it's expensive.

If you look at everything that the solution entails, and the big cost to companies, especially medium-sized companies, one would like to have a bit of a price decrease due to economic circumstances. The functionality is fantastic, but for medium and small-sized companies it's overpriced. It would be better if it were a little bit cheaper.

We did look at other solutions. In the end, we decided on 365 Defender because it was all integrated. It worked to our advantage because all the products that we needed were already on the machines. All the products that you get from the Defender area are part of the built-in Windows 10 features. It gave us a better way of controlling and managing things. Overall, it made more sense to have one central place to manage and control and be alerted.

My advice is don't be frightened when you start getting into the solution. If you are not used to the environment, it is a mouthful, and it can really scare your socks off. There's just so much to it that you won't really know where to start.

The best thing I can recommend to anybody who is starting is to get somebody who knows the system to give you a walkthrough. Also, look at the tutorials to see what the functionalities are. It will be beneficial for any person to get a good overview of what's going on in 365 Defender, the capabilities and how it looks. But getting in contact with somebody who has some experience already in using it will help you to ask where to find things. "Where do I go from here? Show me how you're set up, so I can at least see some of the functionalities."

My very first impression of 365 Defender was that I was looking for something, but I didn't even know where to start. It was too overwhelming. As I spoke to other people who knew about the system, they gave me an overview and that made it easier for me to understand and to know where to go.

365 Defender is our main deployment, but we've got the endpoints also connected on Intune. They work together to deliver coordinated detection and response in our environment. Our complete suite is pretty much all Microsoft. Our environment is a 50/50 hybrid. We use Intune for certain policy changes and some of the deployments. But because our environment has a lot of legacy systems, we make use of the normal, on-prem deployment services as well.

Sentinel is linked to our on-premises Active Directory. It helps identify things that are happening on-prem. For example, when a user's account instance gets locked out, it will show you, on Defender, from which local machine it was locked out. Or if certain things are accessed, it will show that information on the on-prem Active Directory. It works well. For investigating and responding to threats, it definitely helps by dumping the information in a centralized location with the alerts to identify a bit more flow pattern. If something happens that's not on the cloud area, but it's on-prem, it helps track and identify movement. The information from Sentinel is an added bonus.

Overall, Defender 365 has saved us time, compared to the old ways of doing things, but at the same time, I wish the site was faster. Sometimes it can be very slow.

Best-of-breed solutions versus a single vendor's suite comes down to personal experience. With best-of-breed, at least you know that they have been tested in the industry and have a lot of history behind them. Also, the redundancy would be a lot better. Going with a single vendor sometimes makes it a little bit difficult, especially if they are only focusing on one area. It's a difficult question. It might come down to the way someone was "brought up" in the security industry or the way that they trust these companies.

I give Microsoft 365 Defender a nine out of 10. Once you get to know the system, it's really awesome. It provides a lot of insights.
