The solution's timeline feature helps you track and investigate incidents
Pros and Cons
  • "Defender XDR has a feature called the timeline that lets you track all activities. It helps a lot with investigations."
  • "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."

What is our primary use case?

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

How has it helped my organization?

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. 

What is most valuable?

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. 

What needs improvement?

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.

For how long have I used the solution?

I have used Defender XDR for three years.

How are customer service and support?

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

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

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. 

How was the initial setup?

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

What's my experience with pricing, setup cost, and licensing?

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

Which other solutions did I evaluate?

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. 

What other advice do I have?

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.

Easy-to-use product with good stability
Pros and Cons
  • "It has great stability."
  • "There could be a way to proactively monitor unusual activity ."

How has it helped my organization?

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.

What is most valuable?

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

What needs improvement?

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.

For how long have I used the solution?

I have been using Microsoft Defender XDR since 2015.

What do I think about the stability of the solution?

We never encountered stability issues.

What do I think about the scalability of the solution?

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

How was the initial setup?

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.

What's my experience with pricing, setup cost, and licensing?

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

What other advice do I have?

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.

Provides good insights, allows us to prioritize threats, and comes with a centralized portal
Pros and Cons
  • "The EDR features are valuable. By getting the EDR features, we have more control over the device. We have information about events in real-time and more protection against zero-day threats and zero-day vulnerabilities. We can monitor every event or action that a device is going through. We can get an idea if it is something malicious or if we have to take any actions."
  • "The onboarding and offboarding need improvement. I work with other vendors as well, and they have an option to add a device or remove a device from the portal, whereas with Microsoft 365 Defender, we need to do that manually. However, once you do that, everything can be controlled through the portal, but getting the device onboarded and offboarded is currently manual. If we have an option to simply remove a device from the portal or get a device added from the portal, it would be more convenient. The rest of the features are similar. This is the only area where I found it different from others. I would also like to be able to simply filter with a few of the queries that are already there."

What is our primary use case?

Microsoft 365 Defender is an extension of Windows Defender. Windows Defender is an AV that is integrated with Windows OS, and with this extension, you also get the EDR functionality for security purposes. Microsoft 365 Defender gets more access to the device and provides more insights and control over that. Apart from the Windows platform, it also includes other OSs, such as Linux and macOS.

We do have multiple options for deployment. We did deploy it on the cloud. We got the on-cloud license, and we onboarded our devices to the portal. The portal is deployed on the Azure cloud.

How has it helped my organization?

It helps us prioritize threats across the enterprise. We also have options to prioritize a specific device and monitor it. We can keep a device on high alert or on the watch out for each and every event. There are different severity levels, such as critical, high, medium, and low. We can set severities on any of the devices. Based on the set severity level, Microsoft 365 Defender can track events, and we can monitor those events from the console.

We get more insights and more information about the devices that we have. Because most of them are Windows devices, we have integrations with Intune or SCCM. It is easy to transfer all the information and see everything in one single portal. If we want to configure anything or control the devices in the whole organization, it is easy because all of them are in the same environment. It is easy to manage and control them.

There are fewer compatibility issues and errors and a better ability to track events. With third-party solutions, I used to see more issues related to compatibility and setting the ports. For each and everything, we had to either go through the support documents or through the support to get information. Most of the Microsoft documentation is publicly available. It is not that you only get that when you open a support case. That's an advantage compared to others.

It helps to automate routine tasks and the finding of high-value alerts. We have KQL or SQL queries that we can set up. We can schedule them so that it automatically queries for a specific device or all the devices and gives us a report that we can simply export.

Its threat intelligence helps to prepare us for potential threats before they hit and take proactive steps. It has helped us to recover a few devices. Because it is integrated with the OS, we get information about failed logins.

It saves time and manual labor. Previously, we used to use a deployment portal such as Filezilla or GPOs. We used to manually update the signatures, but now, it is automatic. It saved me pretty much half a day's work.

It has decreased our time to detect and our time to respond. It has saved half a day's work. The sensor constantly connects to the console. In case of an issue, we get an email immediately. We also get a notification in the console. Previously, we used to manually scan the device or query something and then get the results. Because it is automated, we don't need to manually do that. Previously, we used to manually isolate or block a device, or we used to work with different teams to get the device offline, but now, we can simply search the device name in the console and isolate a device from there, which is convenient for us.

What is most valuable?

The EDR features are valuable. By getting the EDR features, we have more control over the device. We have information about events in real-time and more protection against zero-day threats and zero-day vulnerabilities. We can monitor every event or action that a device is going through. We can get an idea if it is something malicious or if we have to take any actions.

Because Microsoft 365 Defender is integrated with the OS, we get more insight into the events or threat activities. With a third-party solution, we could have some limitations or compatibility issues with the OS, whereas with Microsoft 365 Defender, there are no compatibility issues for Windows, and we get more insights and more information on the threats simply by logging into the console.

What needs improvement?

The onboarding and offboarding need improvement. I work with other vendors as well, and they have an option to add a device or remove a device from the portal, whereas with Microsoft 365 Defender, we need to do that manually. However, once you do that, everything can be controlled through the portal, but getting the device onboarded and offboarded is currently manual. If we have an option to simply remove a device from the portal or get a device added from the portal, it would be more convenient. The rest of the features are similar. This is the only area where I found it different from others. I would also like to be able to simply filter with a few of the queries that are already there. 

For how long have I used the solution?

It has been almost three months.

What do I think about the stability of the solution?

I would rate it a seven out of ten in terms of stability. It is quite stable but it can be improved for a few scenarios. It is still new for macOS and Linux, and for these OSs, I would rate it a six out of ten in terms of stability.

What do I think about the scalability of the solution?

It is scalable. We are using it pretty extensively. It is for multiple departments, and there are multiple teams handling it. In the tenant I have, there are 2,000 devices that are currently onboarded. We also get information about which devices are not onboarded. I can see that a few hundred devices are not onboarded. We also have a few other clients or partners who are using it but on a small scale. 

How are customer service and support?

It is good. We do get constant responses and inputs from them whenever we raise a case. They are quite helpful. I would rate them an eight out of ten.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I started working with this solution because I changed my organization. That was the major reason. 

Being able to get the information simply from a single portal and the integration with other portals have been some of the benefits. Previously, we used to get data manually, and then we used a SIEM or event collector to send that data to other portals. Now, we can integrate with other Microsoft portals, such as Intune, and get the same information there as well. That's one convenience I have found.

How was the initial setup?

I am not involved with tenant deployment. I am involved with the onboarding of the devices. If you have the right knowledge, it is completely fine. They do have an admin console. You can deploy multiple tenants and also control through that console, but I don't have access to that. I only have access to my own tenant. I only have control over that. We can also include a tenant for a specific organization from the admin console. That admin console is deployed on Azure.

Most of the maintenance is automatic. Because we allow Windows updates, most of the Defender updates are also included in Windows updates. We don't have to specifically go and check. If we see any alert or we find any suspicious events or something on the console while we are investigating, then it might need manual checks. We do get some recommendations through the console itself for what we can do to improve the device security score. So, it requires some maintenance, but that's only when we detect something or we are investigating something. For maintenance, we have different teams in each section. We have around 15 to 20 people.

What was our ROI?

I don't have the metrics, but we started to see its benefits within a couple of weeks from the time of deployment.

What's my experience with pricing, setup cost, and licensing?

Its licensing and pricing are handled by someone else. My role is limited to incidents or issues with the portal, but you get what you pay for. It is worth the cost.

Which other solutions did I evaluate?

We did compare it with VMware Carbon Black and McAfee. We did check Symantec as well, but Symantec didn't have EDR capabilities. So, we dropped it. The final call was Microsoft because we found the integrations and other things easy. It saves time for us because we don't need to go through another team or get a separate team involved just for data transfers.

What other advice do I have?

I would definitely recommend this solution. Getting the product is easy. You simply get the license, but after getting the product, you need to go through the deployment and configuration of the product to match your environment. You can just try out the product and experiment in your own way and learn each and every feature. The documentation is completely public. 

I would rate it an eight out of ten because there are a few areas where it can be improved.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Vast range of audit log search options helps analysts carry out a full search
Pros and Cons
  • "Many people don't realize that Microsoft Azure, Exchange Online, and the security and compliance portal all sync together. For instance, within the Azure portal you can set security restrictions and policies to help secure your tenants... The good part of it is that these products have already been integrated. When you sign on as an admin you have global admin rights and that gives you access to all these features."
  • "The message trace feature for investigating mail flow issues should add more detailed information to the summary report... if they could extend the summary report a little bit, make it more descriptive, ordinary administrators could understand what happened and that the emails failed at this or that point. That way they would know the location to go to try to correct it and to prevent it from occurring again."

What is our primary use case?

We are a Microsoft partner and we have clients who are Microsoft 365 administrators in several companies. They are looking for ways to secure their tenants and make sure that their security is top-notch. That's where Microsoft Defender comes in. We use Microsoft 365 Defender for security and compliance to secure tenants from malicious attacks, including spam and phishing attacks. And when it comes to compliance, it is used for data privacy and data protection to ensure that very sensitive data doesn't go out to the wrong location.

How has it helped my organization?

It makes security and protection very seamless.

And Defender saves me time. For instance, if I get notified that a user isn't receiving emails from a particular person, I know that the first thing I have to do is a message trace. It saves me time to an extent because I have a go-to location. With message trace, I'm able to trace emails from, for example, abc@givendomain.com over the past two days. It gives me information about what actually happened in the mail flow. I'd rate the time it saves me as a seven out of 10. 

It has also saved us money, on the order of 50 percent. And our time to respond has improved to the level of a six out of 10.

What is most valuable?

The features of the solution are vast and wide.

The most valuable feature is the content search feature in the compliance portal. It is very useful because it covers both audit log search and content search. The audit log search is very useful because, most of the time, you see several changes within the admin portal and it's hard to keep track of what happened. Our customers want to get to the root cause and see the activity that must have triggered those changes. That's where the audit log search comes in. They've enhanced the feature in such a way that it has a vast range of search options so that an analyst can carry out a full search.

The content search feature has also advanced to a point where you can carry out several searches with your keywords. You can point it to a certain location, such as Exchange Online or SharePoint Online, or Teams Online. You can narrow the search down to a particular individual or group of individuals. When administrators report that they have lost content or accidentally deleted a mailbox or the mailbox content, the content search feature is a good way to recover the content.

Another top feature is threat management. It helps prioritize threats across the enterprise.

In addition, you can navigate to the security compliance portal and set restrictions to block IP addresses from different locations. You can also choose to flag domains that are sending malicious attacks and block them and update the anti-spam policy to make it more strict to prevent attacks from happening in the future.

Many people don't realize that Microsoft Azure, Exchange Online, and the security and compliance portal all sync together. For instance, within the Azure portal, you can set security restrictions and policies to help secure your tenants, but most administrations do not know about that, including things like multi-factor authentication, conditional access policies, and privileged access.

We've had reports from clients about compromised accounts because someone got access to a password that they shouldn't have. Multi-factor authentication helps eliminate this. As for conditional access policies, you can set certain policy restrictions to certain locations or IP addresses so that emails or sign-ins only come from particular locations. That helps secure your environment against malicious sign-ons to your accounts.

The good part of it is that these products have already been integrated. When you sign on as an admin you have global admin rights and that gives you access to all these features. You will see Exchange Online, security and compliance, and Microsoft Azure. All you need to do is click and it takes you to the portals.

Overall, the comprehensiveness of the threat protection is at 95 percent. It's not 100 percent because of updates not being done on the Knowledge Base and technical know-how.

The alert feature allows you to set the severity of alerts. If there is a malicious or suspicious sign-on, an alert triggers immediately letting you know, as an administrator, to check what's going on in that account. For example, there was a time when one of our users' accounts was about to be compromised. We got an email notification which was sent to all administrators on the tenant. I was able to block that activity in real-time and then set the system to trigger more alerts for such sign-ons in the future. I also blocked the IP address. That particular feature has helped. The alert arrived in real time to prevent the account from being compromised.

What needs improvement?

When changes are done within either the admin or security and compliance portals, there should be a real-time update to administrators about the changes. Many times I'm supporting a case where someone says, "I used to do this like this, but I'm unable to do it that way anymore. What happened?" And I will have to say, "Oh, sorry. That doesn't work like that anymore. It's now done this way." So there should be a way to notify people about changes like that, and prompt information when changes are done within a portal.

I would also like to see regular updates about new features in the Knowledge Base. There are cases where I'm using a Knowledge Base article to try to educate a customer, but when I check the feature on the admin portal, and in the article, they don't look alike. For instance, it's saying, "Go to settings. From settings, go to options." Meanwhile, on the portal itself, I'm seeing "Settings, go to more settings, then go to options." It would help a whole lot if feature updates were updated in real-time in the documentation.

Also, the message trace feature for investigating mail flow issues should add more detailed information to the summary report. The summary report is what the administrators are able to understand. The extended reports are a very deep dive and the administrators will only understand them if they reach out to support engineers. But if they could extend the summary report a little bit, and make it more descriptive, ordinary administrators could understand what happened and that the emails failed at this or that point. That way they would know the location to go to try to correct it and prevent it from occurring again. Making that summary report more extensive and detailed would be of great help.

For how long have I used the solution?

I have been using Microsoft 365 Defender for a little over three years.

What do I think about the stability of the solution?

Overall, it is stable. 

There are a few bugs but they generally don't impact the reliability. The bugs are not the kind that impact the work done by an organization. Processes can continue while they fix the bugs.

What do I think about the scalability of the solution?

It is scalable.

It is used across multiple departments with anywhere between one and 200 endpoints.

How are customer service and support?

Their response time is okay, it works fine, but the time it takes to resolve escalated cases needs improvement. An escalated case is when there is a bug. You could literally have reported a bug and it's still not resolved the following week. Bug fixes take a long time, especially when a very essential feature is not working as expected.

How would you rate customer service and support?

Neutral

How was the initial setup?

It took me three to five months to understand it because it has a vast number of features. If you do not understand it, one click could mess up a whole lot of things.

What's my experience with pricing, setup cost, and licensing?

Microsoft should provide lower-level licensing options. They should do it in such a way that even an individual could purchase a license, and it should be entirely flexible. An individual should be able to access the solution at a very affordable rate.

Which other solutions did I evaluate?

Most administrators, in my experience so far, are reaching out to third parties for email filtering and to manage threats in their organization. According to them, Microsoft 365 Defender isn't giving them the information they need. And I realize that this is not correct. What they're missing out on is the proper information or technical know-how to utilize the features.

For example, if someone uses Barracuda as their third-party filtering service, I begin to ask questions such as, "Okay, why did you choose to use the Barracuda service when we have the ability to create good anti-spam policies that could help secure your tenant? You can create anti-phishing policies and rules that will help restrict IP addresses." Often, what they say is that Barracuda is better because it gives them more information and real-time data. At that point, I ask them to let me provide a deep dive into the features of Microsoft 365 Defender. I use the documentation and Knowledge Base articles to explain its features, one after the other, and they begin to say, "Oh wow." They didn't know these features actually exist. They'll begin to look at the possibility of utilizing the Microsoft solution since they have paid for it. Why should they pay additional money to a third party to get services that Microsoft provides? They feel very happy about the information I provide.

So far so good. The Microsoft 365 product hasn't given me a reason to want to check for other products and move to something else.

What other advice do I have?

For the best and most seamless user experience, it's best to go with a single vendor because there could be a lot of complications going with a best-of-breed strategy. It's easier to understand things with a single vendor.

When you don't understand a feature, ask questions and reach out for support. There are some features that are being used wrongly or that are underutilized.

Also, test the product beforehand. They provide trials so you can test the solution and see if it meets your expectations.

An all-in-one solution that eliminates the need for multiple products or technical controls
Pros and Cons
  • "What I like most about the product is its all-in-one solution. With Microsoft Defender XDR, we get coverage for various aspects like endpoint security, cloud security, and image-related cases, all within a single platform. This eliminates the need for multiple products or technical controls to address incidents. The main benefit became evident immediately after deployment, especially in its ability to analyze files and phishing emails quickly. By submitting suspicious files or emails, we receive quick results on whether they are legitimate, suspicious, or malicious, saving time."
  • "The solution could enhance the threat Intelligence feature by making it more relevant to specific industries. Much of the threat intelligence information isn't directly applicable to our environment. It would be beneficial if the threat intelligence were tailored to the industry, such as healthcare or fintech, where the solution is being used."

What is our primary use case?

We use the solution for endpoints.

The main benefit became evident immediately after deployment, especially in its ability to analyze files and phishing emails quickly. By submitting suspicious files or emails, we receive quick results on whether they are legitimate, suspicious, or malicious, saving time. 

What needs improvement?

The solution could enhance the threat Intelligence feature by making it more relevant to specific industries. Much of the threat intelligence information isn't directly applicable to our environment. It would be beneficial if the threat intelligence were tailored to the industry, such as healthcare or fintech, where the solution is being used.

Additionally, the MDCA feature could be improved to provide more accurate data on how much data is uploaded or downloaded from the cloud. This might involve better implementation from our infrastructure team, but clearer and more precise reporting on cloud data activities would be valuable.

For how long have I used the solution?

I have been using the product for eight to ten months. 

What do I think about the stability of the solution?

The solution works smoothly. 

What do I think about the scalability of the solution?

The tool's scalability is good. 

How are customer service and support?

If we open a case on the Microsoft portal, a support person from Microsoft helps resolve the queries. From our side, it usually involves two or three people. The Microsoft support person sometimes brings in another expert to resolve technical queries.

We've submitted our queries, and a tech support engineer comes through on a chat, a Zoom call, or another type of call. We discuss the queries with them, and they usually resolve the issues in one or two sessions.

Sometimes, if one engineer can't resolve the query, they will bring in another engineer, which can take an additional one or two days. 

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

We chose Microsoft Defender XDR because it provides a one-stop solution. Everything related to endpoint security, email security, or cloud applications is integrated and visible in a single window. If we were to use other solutions, we would need to implement three different products to achieve the same level of integration and functionality.

How was the initial setup?

We had some issues while deploying the tool's on-prem version. Support helped us resolve them. The cloud version is easy to deploy, while the on-prem version takes one month and doesn't require any maintenance.  

What other advice do I have?

I rate the overall product an eight out of ten. If a new customer is going to buy Microsoft Defender XDR, they should clearly state their needs in front of the Microsoft team. They need to specify what they want and what features they require. It's good for the Microsoft team and the customer to understand all the requirements before deployment clearly. This way, any potential issues can be addressed beforehand, making the deployment smoother.

It lets us prioritize threats and automate responses, but the threat intelligence could be better
Pros and Cons
  • "I like Defender XDR's automation capabilities. XDR isn't automated by default, but you can automate it to respond. If an attack is performed anywhere within the organization, you can isolate that instance from the network. This is what I can figure out for it. When integrated with Sentinel, you can set up playbooks to automate all the alerts gathered on Sentinel from different Microsoft solutions. Sentinel has a wider range of capabilities than XDR."
  • "When we do investigations, it would be better if Microsoft could populate the host dashboard more. When we open any host for investigation, we want the entire timeline of what is happening on the host, including all the users logging in, their hardware, Windows version, etc."

What is our primary use case?

We typically use Defender's default settings and are implementing MITRE ATT&CK use cases on Microsoft Defender this year. We do manual threat hunting and check to see if there is a trending attack. We have the latest IOCs and sweep across the organization looking for them. 

When implementing Defender, we usually use its advanced hunting features to determine particular techniques used across the whole environment. We use multiple Microsoft security products, including Defender for Endpoint, Defender for Cloud Apps, Sentinel, email and collaboration, data loss prevention, and Microsoft Purview.

How has it helped my organization?

Defender XDR enables us to prioritize threats according to the algorithm or our custom rules. We can prioritize threats and have the option to automate the response. For instance, let's say we are facing a sticky key hijack. When you press shift several times at the login screen, you can open the command prompt of that particular host. That is a vulnerability of Microsoft Windows. When this happens, we can automate a priority alert and also isolate that endpoint from the network immediately. 

The solution reduces our remediation time by enabling our security analyst to respond quickly, make some automations, and edit the rules to detect any potential threats. The extent to which the solution reduces the remediation time depends on the analyst's skill. If the security analyst is good, Defender XDR will help them.

XDR saves money if you are using Microsoft products. XDR is more inclined toward Active Directory, a Microsoft product. No other XDR can integrate with Active Directory so seamlessly and use it to its fullest potential. Microsoft also offers multiple sub-products. If we purchased third-party solutions for email, endpoint, XDR, cloud applications, etc., and managed them on a single platform, it would be more expensive than Microsoft solutions. When we do a cost-benefit analysis, Microsoft Defender XDR offers a better value. 

What is most valuable?

I like Defender XDR's automation capabilities. XDR isn't automated by default, but you can automate it to respond. If an attack is performed anywhere within the organization, you can isolate that instance from the network. This is what I can figure out for it. When integrated with Sentinel, you can set up playbooks to automate all the alerts gathered on Sentinel from different Microsoft solutions. Sentinel has a wider range of capabilities than XDR. 

What needs improvement?

Defender XDR has good threat visibility, but it could be better in some areas, like when we are hunting for a specific host. For example, let's say we are investigating email services, and want to trace an email account to its host PCs and investigate the emails in its inbox. We want more visibility into the email side of investigations. It would be better if these features could be more integrated into the console like you could have a tab for Cloud Apps to see the cloud applications a user had communicated with. 

Microsoft's threat analytics are somewhat helpful for anything related to Microsoft products. For instance, it can update us about any single sign-on vulnerabilities or something along those lines. However, Microsoft was very late in terms of the recent LockBit attacks. LockBit compromised some significant organizations, and Microsoft didn't provide the report fast enough. It was reported on my normal cybersecurity information websites first. The site analytics are a bit weak when it comes to non-Microsoft clouds.

Defender XDR is capable of providing intelligence reports about threats specific to Microsoft components, but if we are implementing a Microsoft solution across an organization, many other products and side factors must be considered. I feel like Microsoft falls behind some other vendors in threat intelligence.

When we do investigations, it would be better if Microsoft could populate the host dashboard more. When we open any host for investigation, we want the entire timeline of what is happening on the host, including all the users logging in, their hardware, Windows version, etc. 

For how long have I used the solution?

I have used Defender XDR for nearly 2 years. 

What do I think about the stability of the solution?

We haven't faced issues with stability. XDR doesn't lag during investigations. We've seen a few minor bugs in the XDR console but not often. There have been no major issues that disrupted our operation. 

What do I think about the scalability of the solution?

Defender XDR has good scalability. If you want more endpoint visibility, you don't need to scale your organization much. You only need to integrate that particular endpoint by running a script and deploying an agent to it. 

How are customer service and support?

I haven't contacted Microsoft support about XDR, but my client has. One of the alerts was triggering incorrectly based on a default setting. We asked their team to investigate why the solution was excessively triggering. I just disabled the default rules and made custom policies. Now, everything is working fine.

Which solution did I use previously and why did I switch?

I previously used CrowdStrike EDR. It's hard to compare the two products because CrowdStrike EDR was focused on endpoint detection, so it cannot investigate emails or have any other XDR capabilities. One is an XDR and the other an EDR. 

Which other solutions did I evaluate?

We compared Microsoft Defender XDR to Trend Micro's Vision One. Defender's advantage over Vision One is ease of use. Managing and enabling policies is much easier on Microsoft Defender. There's a considerable difference between their default rules. In some cases, alerts will trigger in Defender, but not Vision One. Overall, Microsoft Defender XDR is preferable over Vision One.

What other advice do I have?

I rate Microsoft Defender XDR 7 out of 10. It's a useful product for a professional security analyst who knows how to increase the visibility. You only need to make some front-end changes and put the data on host names into XDR. 

If someone asked me whether a best-of-breed or single-vendor approach is better, I would support mixing different products. Each security vendor has its own intelligence base. By including other vendors, I am gaining visibility into more indicators of compromise. Nevertheless, I would still pick Microsoft Defender XDR and Sentinel together because they are well integrated. All the big companies and banks use Microsoft. Windows is a popular operating system across the world. Defender and Sentinel are better integrated with Microsoft systems.

It isn't customizable enough and not all of the solutions are fully integrated
Pros and Cons
  • "My clients like Defender's file integrity monitoring. They're monitoring Windows and Linux system files."
  • "My client would like the solution to be more customizable without using code. You can only build on the default console, but we're not allowed to change it."

What is our primary use case?

One of my largest customers deployed Defender for Endpoint, but they also wanted Defender XDR to get a specific feature. Defender XDR is included in the E5 license, but it's a bit too expensive. Our customer wanted Defender XDR's file integrity monitor tools for compliance. My client is using Defender with Sentinel, but I'm unsure how much they use it. 

What is most valuable?

My clients like Defender's file integrity monitoring. They're monitoring Windows and Linux system files.

What needs improvement?

My client would like the solution to be more customizable without using code. You can only build on the default console, but we're not allowed to change it. 

We have a similar tool to Defender's file integrity monitoring. Under the VMware VM properties, there is a change-checking tool, and it will tell us if the extension is in a different location. You can configure checking and do the monitoring. When I log into Defender's file integrity portal, I cannot see that this machine was enabled.  It's the same agent and extension. 

It's confusing because I don't know how to tell the customer they don't need to pay $15 per month because you already can enable the extension in VMware. Under the Defender account, it all seems like it's high code, and we cannot change it. Every customer has requirements for us to customize those things. 

For how long have I used the solution?

I have used Defender XDR for about a year. 

What do I think about the scalability of the solution?

Defender XDR is an enterprise-scale solution. 

How are customer service and support?

I rate Microsoft support 4 out of 10. 

How would you rate customer service and support?

Neutral

What other advice do I have?

I rate Defender XDR 3 out of 10. I don't think Defender XDR is ready to deploy in its current state. It has too many solutions inside, and they're not fully integrated. 

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Microsoft Azure
