Microsoft Defender XDR Reviews

We mainly use it to defend endpoints.

We have seen fewer threats with the solution. The attacks that we experienced in prior years have reduced drastically since we implemented Defender.

We also use Microsoft Defender for Identity. Their integration is very good. If you are a Microsoft 365 SaaS solution user, it is perfect. It works very well with all the services provided by Microsoft. These services work natively together to deliver coordinated detection and response across our environment. We are pretty much a Microsoft shop, so the integration of these different services is very important for us to secure our offices.

Microsoft 365 Defender's threat protection is very comprehensive. The service that is available now is much more comprehensive than what was available a few years back. The only area that I see lacking is the dashboard. I can create my own dashboard, but the preset security dashboards should be much more functional.

Its threat intelligence helps prepare us for potential threats and take proactive steps before the threats hit. The vulnerability scanning feature is great, and the Secure Score feature that scans the endpoints for vulnerabilities and keeps them up to date reduces a lot of the attacks that can possibly happen.

Microsoft 365 Defender has saved us time. It has saved at least 30% to 40% of our time.

Microsoft 365 Defender has saved us costs. Previously, we had to pay for third-party protection services separately, but because it is now integrated with our E5 licenses, it saves us a lot of money.

Microsoft 365 Defender has decreased our time to detect and respond. We now have visibility and this led to about a 20% to 30% reduction. 

The EDR and the way it automatically responds to ransomware and other attacks are valuable features.

The visibility into threats is not as good as other products in the market such as CrowdStrike, but if you know where to look, you can gain access to what is going on. The way the dashboard is designed is not as great as other products.

It helps to prioritize threats across the enterprise, but a lot of administrative overload is involved in determining which threats to prioritize. As compared to other products, it is a bit lacking.

Similarly, it helps to automate routine tasks and finds high-value alerts, but a little bit more automation would be appreciated.

Automated playbooks and automated dashboards would be preferable to the way the data is currently being presented. That is because a lot of organizations that I have worked with over the past years do not have full-on SOC or threat detection services. They should put in more automated response capabilities and dashboards for smaller organizations.

I have been using this solution for almost three years.

It is a very stable product. Our attack metrics have come down drastically since we integrated with Defender. In my opinion, it is a very stable product.

It is very scalable. I do not know about third-party clouds or third-party solutions, but when you are a Microsoft shop or have Azure or a hybrid setup, it is very scalable.

We have multiple departments and multiple locations. We have client-facing computers, and we have in-house and on-prem computers. We also have Azure VMs. 

Their support can be better. Their response time is good, but their knowledge and documentation are a bit lacking. Technology is moving faster than the documentation and the knowledge that is being provided to the support team. Their support team pretty much looks at the same documentation that we are looking at, but the technology is moving a lot faster than they can catch up. I would rate their support a seven out of ten.

We used CrowdStrike and Trend Micro. We switched to Microsoft 365 Defender because we wanted to integrate services.

The solution is deployed on the cloud, but the endpoints are connected on-prem. In our organization, we have quite a few endpoints, so it took about three or four weeks.

The setup will be straightforward for big organizations if they have a complete IT department, but for a small organization, implementing the same service becomes trickier because they do not have full-fledged IT departments. That is where the problem lies. 

More automation would be better. However, automation is present with Autopilot and other services where you can integrate everything.

In terms of maintenance, you have to fine-tune the services on a regular basis and tweak the deployment as per your requirements.

We have about eight admins who worked on the implementation of the solution.

We have probably seen 30% to 40% ROI.

It is fairly priced because we get complete integrated services with the E5 license.

To a security colleague who says it is better to go with a best-of-breed strategy rather than a single vendor’s security suite, I would say that a single-vendor strategy worked for us because it brought down our investment in terms of licensing and cost. The deployment across the organization has been a lot easier than integrating third-party solutions in different areas of the organization. For example, Defender integrates very well with both the endpoints and the cloud. Whereas with a third-party solution, we have to get different applications that need to connect back to the service to get the solutions that we require. Native integration is very useful for us when it comes to Microsoft. That is what I would recommend.

If you are a Microsoft shop, I would highly recommend it, but you have to do a PoC.

I would rate Microsoft 365 Defender a nine out of ten.

I'm a Security and Compliance consultant providing 365 Defender as a security solution for my clients.

All our solutions are Microsoft 365 products, including security, identity, etc., so we have better protection from advanced cyber attacks. It's also easier to ensure compliance with data regulations through the Microsoft Purview portal, which has templates for various regulations on medical privacy and personal data.

365 Defender helps us automate routine tasks and prioritize high-value alerts. Automation allows us to use time more efficiently. It makes functions easier by consolidating data from multiple Microsoft portals into a single dashboard. You can customize the playbook however you like and get a centralized view of the various components.  

The Threat Explorer feature helps us understand emerging threats in real-time and take steps to safeguard our environment. 365 Defenders saves us money because it's a bundle. If you purchased each of these solutions as a standalone product, it would cost you more than $60 per user per month, but you get them for $12 a month in a package. 

365 improved our detection and response times because we catch issues earlier in the chain of events. All the components of 365 Defender work together to provide instant detection. 

The most valuable feature depends on the scenario. For compliance, I like Microsoft Purview Information Protection and Data Loss Prevention. Sentinel is the most helpful feature for security. 365 Defender helps us prioritize threats across an enterprise. It's a crucial feature for the managed services team. 

I also have Defender for Cloud Apps and Defender for Office. Integrating other Microsoft solutions with 365 Defender is seamless. Microsoft has better documentation than some other solutions. I also work on AWS, but I feel more comfortable with Azure. There are some limitations with a standalone license, but integrating Microsoft products is a seamless experience that produces insightful analytics.

Sentinel enables us to ingest data from our ecosystem, giving us a complete picture of the entities associated with an incident. Those analytics are pretty helpful. We develop playbooks customized for any executive or developer-based summary. It depends on what we want to show and our creativity. 

365 Defender has multiple subsets, including Defender for Cloud Apps. When integrating Defender for Cloud Apps with apps on third-party cloud platforms like AWS or GCP, there are limitations on our ability to control user activities. If Microsoft added more control over third-party products, that would be a game-changer and help us quite a lot.

I have used 365 Defender for five years.

365 Defender is stable.

365 Defender is scalable. It's easy to create and manage groups, set policies, and add users. 

I rate 365 Defender support a seven out of ten. When I raise a ticket, I'm usually redirected to a third-party vendor like Convergence. I would prefer it if Microsoft India handled our tickets instead. That would be helpful. The third-party vendor sometimes doesn't have comprehensive knowledge of the product. 

Neutral

The deployment varies from client to client. Our implementation strategy is based on the client's business requirements and the RFP. You need at least two people to deploy 365 Defender, but you might need more support staff for larger jobs. 

It all depends on how a client wants to proceed, but we typically perform an audit before consulting to identify missing components or security controls. For example, if the client requires HIPAA compliance, we must control the data about specific patients. After following up on everything, we recommend the appropriate Microsoft product, and each has a separate timeline. 

I'm on the consulting side, so once we are done with the implementation, a managed services team takes over the maintenance on an SLA of one to three years. 

The price of 365 Defender is reasonable. 

I rate Microsoft 365 Defender a ten out of ten. Microsoft is a one-stop solution, and it has an answer for any problem you're facing. Before implementing 365 Defender, you should be clear about the problem you want to solve. Hiring a consultant can help, but typically, my clients know maybe three out of the five things they should know. 

We are a managed security service provider, and we use Microsoft 365 Defender to provide EDR and endpoint, and email protection to our customers.

Microsoft 365 Defender has great threat analytics integration. It has visibility into threat incidents that occur across different organizations, and this is directly integrated into the tool. Rather than checking for indicators that are available online, we can directly look at which endpoint or user has been impacted in the organization, and this makes our job easier.

Another valuable feature is vulnerability management. The inbuilt vulnerability management service automatically scans devices for vulnerabilities and separates them as critical and non-critical. We don't need to have a separate vulnerability assessment device.

In terms of prioritizing threats, we have come across vulnerabilities and threats that are present in our customers' environments and have been able to discover the devices that are vulnerable to particular attacks. We have then been able to immediately inform our customers and help them update to the latest version of the particular software that was vulnerable. There are automatic response actions in the tool so that a threat can be remediated within the tool itself.

I also like the lab devices that are available within the tool itself with which we can do all the tests. We can simulate some threat activities in these lab devices that are provided by Microsoft and don't need to prepare a separate device to validate it or to simulate a threat tag duty.

The threat intel integration provides great visibility into threats. Microsoft has a huge team that handles threat intel research, and their findings are integrated with their tools like Defender or Sentinel. The features within the tool itself work very well. There's an automatic threat handling module available in the tool, and there are lots of threat handling queries specific to different attack campaigns. We can run those queries to know if any IOCs related to those are present in the devices. Also, there are several inbuilt analytics rules available.

We have integrated Microsoft Sentinel and Office 365, and Defender and Sentinel as well. Some, like Office 365, are natively integrated, and there are connectors available for those that are not. It is easy to integrate the solutions. For example, to integrate Defender and Sentinel we just deployed a connector. There was a short latency period, but other than that, it was seamless.

The automatic investigation and remediation (AIR) feature helps to automatically investigate and terminate many of the malicious files. Without this feature, we would have the difficult task of going to each and every endpoint to delete a particular file or prevent execution.

Microsoft 365 Defender has eliminated the need to look at multiple dashboards and has given us one XDR dashboard. We have a wider range of visibility from a single pane of glass, which also makes it easier to manage.

Regarding saving time, the key has been the fact that everything can be managed from a single pane of glass where we have visibility into all of the endpoints and users. Previously, we had to look into each device belonging to the customer before deploying a solution. Automatic remediation and vulnerability management features have saved us a lot of time. The time-savings have resulted in saving us money as well.

Offboarding latency should be reduced. Even after a device has been successfully offboarded using a particular offboarding script, it still shows up as onboarded.

Licensing is also confusing, particularly with regard to Microsoft Defender for Endpoint.

A good feature to add would be automatic patch deployment. Currently, the vulnerability management feature shows all of the vulnerabilities present in different devices that have been onboarded. It shows what manual actions can be taken or what patches can be deployed, but automatic patch deployment is not an option. It would be great if a patch can also be deployed right from the tool.

I've been using Microsoft 365 Defender for 1.5 years.

Other than a few times where we faced issues with hanging, the solution has mostly been stable.

It's a very scalable tool that can be used in a very small environment or in a very large environment. Everything can be managed from a simple dashboard and can be scaled up or down depending on the customer's environment.

We have had to rely on technical support quite a few times, and they have been very responsive. I'd rate technical support at nine out of ten.

Positive

Because it's a cloud solution, Microsoft 365 Defender is easy to deploy.

I prefer to go with a best-of-breed strategy rather than with a single vendor's security suite, but the tool would need to integrate with as many products as possible, as in an open XDR strategy. However, if you can't integrate with multiple devices by having an open XDR tool, it's best to have a single vendor's tool in order to have greater integration.

If you are looking into Microsoft 365 Defender, my advice would be to make sure that you know your licensing requirements. If you already have a Microsoft-based environment, then this solution may be a good fit as it will integrate with all other Microsoft products. Also, Microsoft is constantly improving their solutions, and it's a good time to be in the Microsoft security sphere.

Overall, I'd rate Microsoft 365 Defender at eight on a scale from one to ten.

We manage around 5,000 computers inside and outside our company. I use Defender to work on our security score by deploying security policies. We apply all the security recommendations to our computers and patch all third-party applications. We check every day for malware to alert our security teams.

Seven months ago, our security score was 50 score and it's now 84. We applied all the security policy recommendations coming from the solution and we became aware of the vulnerabilities and fixed them all, one by one.

We can also automate some tasks and that reduces daily work. And if we get an alert, and we know it is not a false positive, we automate things so that we don't get that alert again.

And if we find malware or a threat, we transfer it to level-one technical support to check and, after that, to the security team. But a lot of times, it catches malware and takes action to block it automatically.

Defender has also saved us money, about 30 or 40 percent. When we had Symantec, we suffered one attack against our company and we lost a lot of data and a lot of servers, and that was a lot of money. Since switching, Defender has been perfect, catching all malware and taking action automatically.

It has also decreased the time it takes me to check everything. I now spend only one or two hours a day monitoring things.

I like that it's fully integrated with Windows, Microsoft 365 Exchange Online, and Outlook. It is better than other antivirus solutions because it's fully integrated with all Microsoft products. It's easy to integrate them and onboard all Windows devices from SCCM. That is really amazing. Everything is clear in Defender. It's not difficult.

Also, everything for security is in one dashboard. It's great. It's not only for Defender but email and everything else. it makes things very easy. I can check everything at once.

The dashboard should be easier to use. There is also improvement needed in the reporting when it comes to exporting or scheduling reports.

I have three years of experience with Microsoft 365 Defender.

It is very stable.

It is also scalable.

On-prem, we have around 300 servers, a mix of Linux and Windows. We also have around 5,000 clients, all using Windows 10 and 11. We have a plan to migrate all on-prem servers to Azure. In the next six months we are looking to migrate 90 percent of them to the cloud. 

I like their support sometimes.

Neutral

We used Symantec for antivirus and security and we migrated all users from Symantec to Microsoft 365 Defender. It's easier to use than Symantec or McAfee and we can use it anywhere because it's a cloud solution. Also, with Symantec, we suffered an attack and it did not do anything. In addition, we already had an E5 license with security so we decided to use this license more fully.

I onboarded it to all machines using the configuration in SCCM. It was very easy. It didn't take much time.

We checked McAfee but we went with Microsoft because it has improved its product very quickly. Microsoft Defender of five years ago is not like it is now. Five years ago it was nothing, but Microsoft has improved it very quickly.

It works with Microsoft Sentinel and integrates well with that, but we do not use Sentinel in our company.

I am a purple teamer in my current job, so I also work with detection response in my organization. My job is to configure alerts and monitor incidents, and to do that, my company uses Microsoft Defender XDR. My company has endpoint detection tools for all the endpoints in the organization, and through Microsoft Defender XDR, we are able to get a top-down view of all the incidents on a daily basis and then actually be able to even customize what kind of alerts we want to look for and what kind of attacks are happening. One of the things that I personally love about the tool is the attack story that it provides. Every time there is a specific incident, it creates a graph and maps it to Mitre Att&ck Framework, so it could be initial access, or you may have malicious activity within the network. The tool can track all of the aforementioned areas, and it gives a confidence level. For example, if it is a high-confidence, high-risk alert, then the tool would probably quarantine that particular endpoint on its own, and then an investigator goes on there and actually verifies it. In my experience in the last six months, the false positive rates have been close to zero. Every time there is a case of high confidence alert, there has never been a case where it was not a malicious activity, and it is something I love about the product.

In terms of the most valuable feature of the product, I think it stems from the way it classifies incidents, as it is the most important area in my field of work. Another valuable feature of the tool is threat hunting. For example, there could be a chain of phishing emails that are being sent to our organization, and it may come up as an alert. Then, I know that I can use the artifacts, after which it gives a list of artifacts, which could be email addresses or IP addresses, to identify the threat actors. I can then go ahead and hunt for them across all endpoints within the network, making it essentially something similar to an SQL query that I can run based on what I am looking for. I get more leads in terms of which other mailboxes this particular phishing attack might have gone to where the user may not have interacted with it. The tool allows us to be more proactive in terms of getting close to the initial compromise. I think the threat-hunting feature is coupled with the alerts that my company has configured, and it allows us to proactively stop attacks, which is probably the most important thing for us.

I think that the tool can do a lot of things in a pretty effective way. A lot of times, one of the things I look at is how the false positive rates are, and so far, I see that they have been close to zero. Honestly, I don't think there is a lot in the area of false positives where the tool could improve. I do think that maybe having a feature within my organization where there are three different domains within which we have to operate would be helpful, as there is currently no unified view within the domains. Within a specific Active Directory, you can have Microsoft Defender XDR running, and so everything, including all the endpoints in that domain, are areas you are able to look at from one particular user interface, but there is no feature in which you can merge two different domains. For example, if there are xyz.com and abc.com, all of the endpoints within each of the domains, our company will have a separate UI from Microsoft Defender XDR, and because of it, we have to monitor three different UIs at each point in time. There is also a lot of automation that I have put in place, so every time there is a high-risk alert, our company gets an email in our InfoSec mailbox essentially. I think having a feature where you can merge everything onto a single dashboard would be something from which my company would definitely benefit because it's just a lot of sifting through different user interfaces and then collating data from it. In our company, we should just make sure that we are able to respond immediately, especially whenever there is a security issue within the organization.

I have been using Microsoft Defender XDR for six months. My company is a customer of the product.

I have been in the company for six months, and I think there has only been one time where I remember there was a bit of a slowdown which was associated with the antivirus server and it was not related to Microsoft Defender XDR. Considering the aforementioned issue, my company had to raise a ticket for support, but it has only happened once.

So far, the scalability offered by the product has been fine because it serves as an internal tool managing essentially all of the endpoints within the network, which essentially includes all of the employees, servers, access points, and all of that. In the last six months, my company has not really scaled up the use of the tool that much, and so the numbers have been constant, more or less. If my company ever plans to double up in size in a short period of time, it will probably be the time when the tool's scalability will be tested. I don't think I have the data points right now to answer questions related to the tool's scalability feature.

I have contacted the product's support team. I feel that Microsoft offers a very good support team, as they are usually well-equipped, and the support team members are currently the ones who set up the tool from scratch. The support team has complete visibility of the environment. Every time there is an issue, it gets resolved within 30 to 45 minutes, sometimes more if it is a bit complicated. For example, if the server is slowing down for some reason, the support team is able to sort it out pretty quickly. I think my experience with the tool's support team has been pretty good. I rate the technical support a nine out of ten.

Positive

Before Microsoft Defender XDR, I used some other solutions of the past. In one of my previous organizations, we used to use an SIEM solution like Splunk. The company had a lot of open-source tools, so we used Microsoft Defender XDR and ELK stack to generate alerts from a network monitoring point of view. The company also had Snort rules running on the same endpoint, which was like a blue team device for monitoring the network, and we also had a Splunk Universal Forwarder on the endpoint that was connected to Splunk's server, which was useful for visualization. Splunk was not an XDR tool; it was more about monitoring alerts that we had configured within the organization, customizing them, and making sure that we were able to catch threats based on signatures. There was less automation in the sense of how you can react to an incident. For example, in Microsoft Defender XDR, the moment there is a high-risk and high-confidence alert, it quarantines the endpoint or that particular mailbox and sends an alert to our company, and in such a manner, it stops the attacks, and also lets the investigators know that it is not a false positive, which is something I was missing in a SIEM solution that I used in the past. Alerts were being generated from Snort, and the company where I used to work had an ELK stack running, so we configured the alerts on it. The company also had a Splunk Universal Forwarder that would forward the alerts to a Splunk interface, and it is where we used to visualize all the alerts. In general, it was a combination of different tools that allowed my previous company to have the aforementioned process in place.

The solution is deployed on the cloud model, and our company has opted for the cloud services offered by Azure. In our company, we have Microsoft Access Control Service in place, so everything is controlled through Azure. If there are new members in the team, we give them read-only access to XDR through Azure, so it helps manage the identity and access, and then you can access Microsoft Defender XDR's portal. Our organization also creates specific IDs for every investigator to access Microsoft Defender XDR.

I don't think I can speak much about the pricing model of the product because it is not something I work with, and so I don't know the amount of money being burned by the company for the solution, making it an area beyond my visibility. With the little idea I have about the costs, I can say that XDR tools tend to be a bit expensive. If you are using Microsoft Defender XDR, then you need to go for a subscription-based pricing model. In my organization, which is a relatively large company with close to 3,000 employees, the solution works out well for us. For example, if I had a startup, it probably wouldn't be cost-effective to have an XDR solution in place, and that is where I would probably look at more open-source tools to work with and maybe have a SIEM solution which was a startup, a reason why we had to rely on open source tools. My previous organization also had opted for a subscription to use Splunk, which was expensive, but it was better than getting an XDR tool.

Speaking of whether I started to see the benefits of the product immediately after its deployment or if I had to wait for some time, I would say that Microsoft Defender XDR has been in place from the time I joined my current organization. I immediately saw the benefits of using the product. I wasn't present in the organization at a time when they had moved initially to Microsoft Defender XDR, so I can't speak about the time point during which others in the company saw the benefits or effects of the use of the solution. I think the tool has been very efficient because I have worked in other organizations where they were not using Microsoft Defender XDR, as they preferred SIEM solutions. I have seen that in scenarios where SIEM-based tools were used, it was more of the investigator who had to figure out what was happening because you just had a ton of data coming in from the bottom up. In my previous companies, we had a Splunk interface through which we could indulge in monitoring. I see a stark contrast between the previous products and Microsoft Defender XDR, and it is because the latter-mentioned tool not only allows you to get that bottom-up view where whatever is happening on an endpoint level, I am able to monitor while also being able to push things from the top to down. For example, if I wanted to quarantine a particular file on a subset of endpoints, I can do that from Microsoft Defender XDR, where I can put it on a block list and mark it to a particular Active Directory group, after which I am able to then block that out. The tool is quite effective from a detection and response point of view.

If I consider whether it is better to have just one solution instead of a combination of tools, I would say that it is always better to have a combination of products. The SIEM solution I had used previously was quite efficient in collecting data and in being able to process large amounts of data from where we had a lot of endpoints within a particular network, which I think was fast in many ways. Microsoft Defender XDR internally does the same thing as an SIEM solution. If you ask me, it is always best to have an SIEM solution integrated with an XDR tool because most SIEM products are very good at handling large amounts of alerts, and if you have configured it properly, then you can have a very precise view of what is happening at any given point in time within the network, and once you have it, you can have that database forwarded to XDR that can push down. The XDR tools are very good at classifying events. If you have actions in place as to what needs to be done, then, for example, if an email is marked under the phishing category, you would want to get rid of it from the inbox first. Ideally, it shouldn't even land in the inbox, but if it does, then you want to quarantine it. Pushing a certain action down to the affected devices, I think XDR tools do it brilliantly. I think it is always good to have a match between a SIEM tool and an XDR product or a customization between different tools to help achieve your goals.

The product does require maintenance. With the cloud instances that host the server, our company continuously monitors the health, as we have health checks in place that generate alerts in case something goes wrong, a major reason why we use Microsoft Defender XDR. My company also has Kaspersky's antivirus server, which is essentially hosted on a different server. Sometimes, because of the number of endpoints we have in our company's network, the server does slow down due to resource constraints. It is not my job to maintain the servers in my company, but we have a different team that deals with it. In our company, we do have a couple of instances where the servers are internally managed.

I think Microsoft Defender XDR is one of the best detection and response tools I have worked with as it is quite effective in flagging serious threats for the organization. In our company,we have faced multiple attacks over the last few months, but none of them have been successful, and I think Microsoft Defender XDR has played a major role in it.

Firstly, potential users of the solution should consider that the tool comes with a lot of already customized alerts for any Active Directory environment, but it is always good to understand, especially if you are a new user of the tool. Even if someone is new in the security team, I think it is that person's job to analyze the business, the kind of attacks you could expect coming in, and the kind of visibility that the organization provides on the internet. Once a person gets a good idea about the aforementioned areas, you need to customize alerts and create custom alerts for your organization because that is an area that is going to be unique and different for each and every company, so it won't ever be the same. Microsoft Defender XDR certainly helps with mapping the seven steps of the cyber kill chain, and if the product sticks to it and looks at every single step, lists down the kind of threats, and then customizes the alerts according to that, I believe the users will have a successful time in being able to detect threats before they happen or even while they are happening.

I rate the overall tool a ten out of ten.

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.
