Microsoft Defender XDR Reviews

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.

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.

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.

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.

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. 

It has been almost three months.

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.

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. 

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.

Positive

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.

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.

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

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.

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.

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.

We use the solution for endpoints. 

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.

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.

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

The solution works smoothly. 

The tool's scalability is good. 

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. 

Neutral

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.

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.  

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.

We use Microsoft Defender XDR for our Microsoft 365 email service.

It helps protect us against ransomware. We were a victim of a malware attack in 2018 before implementation.

Email protection is the most valuable feature of Microsoft Defender XDR.

The price has room for improvement. The price should be adjustable by region.

I have been using Microsoft Defender XDR for almost 5 years.

Microsoft Defender XDR is stable.

Microsoft Defender XDR is scalable.

The technical support is good.

Positive

Microsoft Defender XDR is priced high.

I would rate Microsoft Defender XDR 8 out of 10.

No maintenance is required from our end because it updates with the OS.

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.

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. 

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. 

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. 

I have used Defender XDR for nearly 2 years. 

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. 

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. 

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.

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. 

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.

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. 

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. 

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. 

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. 

I have used Defender XDR for about a year. 

Defender XDR is an enterprise-scale solution. 

I rate Microsoft support 4 out of 10. 

Neutral

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. 

It is an integral part of our security infrastructure, primarily serving to monitor both our server and client environments comprehensively.

Its strength lies in providing a holistic view of the protection it offers. When a threat is detected, the system not only identifies the nature of the threat but also provides valuable insights into how and why it was detected. This thorough understanding empowers us to take well-informed steps to remediate the threat effectively. The unified Microsoft environment enhances overall ease of use, making it considerably simpler for our team members to collaborate and work efficiently, given our familiarity with Microsoft products. Unified identity and access benefits stand out as crucial, especially as we delve deeper into compliance considerations. The increasing importance lies in having a centralized view, streamlining visibility through a single interface rather than navigating across various sections in Defender.

The incident threat response and its ability to facilitate effective remediation against threats are the standout features. I haven't encountered a similar level of comprehensive incident response in other solutions before.

Perhaps there's room for visual enhancements to make the platform more appealing. Stability could be improved by avoiding frequent changes to the interface.

We have been working with it for approximately a year.

It has proven to be scalable within our organization, which, while not exceptionally large, consists of around eight hundred users globally. It strikes a balance, meeting our needs effectively without being overly complex.

The technical support is generally good, but we sometimes find the first-line support process a bit cumbersome. After initiating a case, we, as experienced professionals, go through the standard script diligently (ABC), only to find that first-level support requests the same steps again. While I understand the need for thorough troubleshooting before escalation, it can be time-consuming. I would rate it six out of ten.

Neutral

Compared to antivirus or security products such as Trend Micro or McAfee, Microsoft Defender XDR appears notably more user-friendly and offers a clearer interface. The adoption of Microsoft Defender allowed us to phase out the use of other security products, including our long-standing reliance on McAfee and Trend Micro. The transition was prompted by the effectiveness of Advanced Threat Protection offered through Microsoft Defender 365. The decision to consolidate under Microsoft's umbrella proved advantageous, making the adoption process smoother and more efficient for our organization.

The initial setup wasn't overly complicated. We only needed to create a few scripts, which were then executed on our local machines within the environment. This process seamlessly integrated the machines into Defender within our tenant.

We use a third-party software tool for executing scripts and deploying software packages.

We've achieved significant cost savings, primarily in the realm of security. As Microsoft continues to enhance Defender, we anticipate further opportunities to streamline and consolidate various aspects of security monitoring and software under the Microsoft umbrella. I'd estimate the savings to be in the tens of thousands of dollars annually.Considering our relatively small team of around thirty IT professionals, especially those at the first level primarily using security products like Defender, the streamlined access within the same application prevents them from having to navigate through multiple applications. This efficiency translates to a potential saving of around a dozen hours per month per individual.

Understanding the subscription model has been a bit challenging, as every feature or requirement comes with an additional cost.

Overall, I would rate it eight out of ten.

I've been using it for endpoints and for Microsoft 365, along with Microsoft Defender for Identity. I use it to create policies for anti-spam, anti-malware, anti-phishing, as well as safe links.

I also use it for the security score, making sure that our company achieves a good security score across the organization.

It has helped us increase our rules and policies, protecting our users, information, and data.

When I deploy a policy for anti-spam or anti-phishing, the solution automatically helps us mitigate those kinds of attacks that could expand across the organization. The automation stops those attacks and emails and sends the emails to a secure place where the admins can accept or eliminate them.

It has also eliminated having to look at multiple dashboards, which not only makes things easier, but helps us detect, and see for ourselves, the threats that are happening across the organization.

In addition, the threat intelligence helps prepare us for potential threats, providing us with security steps to take based on what other experts have done, the steps and recommendations, to prevent those threats. It collects information from the website that Microsoft has where security experts provide information.

And with our endpoints, it has helped us save time because, before we installed Microsoft 365 Defender, we had an antivirus solution that took our time. In addition, by using Defender for Identity, we have been saving time with the password self-reset, because we no longer need IT members or administrators to help reset users' passwords. They can do it by themselves. And with Microsoft Defender for Cloud, we're no longer installing the software on their computers, so there are time-savings as a result.

And one of the greatest characteristics of 365 Defender is that it natively helps you coordinate, detect, and prevent threats, and it provides investigations across the organization's domain. And with the responses across the endpoints and various resources in the cloud, it has many sophisticated solutions integrated to protect against cyberattacks. It has absolutely helped us to save money because it is just one solution, rather than paying for multiple services at the same time.

The security score and the threat intelligence are really good features. I also like the Exchange message trace.

The visibility into threats is also very impressive because Microsoft helps you predict things and provides analytics to help you really improve your security. And all of this technology works across the domain, so it is pretty helpful in terms of threat analytics. It immediately detects and tells you what you can do, with recommendations.

The solution also indicates threats as high, medium, or low priority. When the priority is high, that is when I put all of my effort and knowledge into it, and focus on it, because it is valuable for the enterprise.

We also use the solution's role-based access control across the organization. Because, as a company, we work remotely, we make sure that our users have access to what they need and we better protect our company from intruders and cyberattacks.

Intrusion detection and prevention would be great to have with 365 Defender.

I've been using Microsoft 365 Defender for nearly a year.

The stability has been great so far.

It's very scalable. That's one of the benefits of the cloud. You can scale or downsize it whenever you want.

We have many locations and departments around the world. I'm located in the Dominican Republic, but there are people in Europe and the United States.

Their technical support is great because they mostly provide responses in less than 24 hours.

We were facing downtime with our Outlook email, and they told us what was happening with our data center. After they responded to us, we provided the information to the head administrators. After two hours, they restored our services.

Positive

The solution doesn't require any maintenance, as far as I have seen.

Between a single- and a multi-vendor security solution, it depends on whether you are using multiple technologies. Microsoft solutions are pretty much integrated, and help you with the pre- and post-breach. If you are using Microsoft, I would absolutely recommend Microsoft 365 Defender. But if not, I would recommend something else because, with just Microsoft, you probably would not be getting the best solution. There would probably be latency.
