Microsoft Defender XDR Reviews

We use Microsoft Defender XDR for antivirus, threat intelligence, and email blocking.

Microsoft Defender's XDR platform provides unified identity and access management. It has improved significantly, although other products remain slightly ahead. I would rate it among the top four or five XDR platforms I've used, and Microsoft is continuously enhancing its capabilities. Overall, it's a fairly good solution.

Consolidating identity and access management under one umbrella within Defender 365 offers significant advantages. This unified approach simplifies control and visibility, eliminating the need to navigate through different screens from multiple vendors. With everything centralized, we gain a comprehensive overview of all IAM activities and can easily access specific details through subcategories. The main page provides a clear starting point, highlighting key information and granting quick access to deeper levels of detail when needed.

While Microsoft Defender can effectively impede the lateral movement of advanced ransomware, it cannot guarantee complete protection. No system is perfect, and vulnerabilities will always exist.

Defender's ability to stop attacks includes its adaptability to evolving threats. Microsoft has been steadily improving Defender over the past few years, and they continue to do so. Several updates in recent months have changed Defender's functionality, making it more effective. While technology advances and tools like Defender improve, the skills of hackers and their tools also evolve. This necessitates continuous improvement to keep pace.

Adaptability to evolving threats is crucial. A static system is vulnerable to attack. Its unchanging vulnerabilities can be readily identified and exploited, allowing unauthorized access and manipulation. Constant improvement is necessary to maintain security.

While we have reduced our reliance on other products, we haven't eliminated them at this time. We are actively reducing our use of other products as we progress. Once we have completed the configuration and setup process for Defender XDR, we can then fully transition to using it as our primary product.

Defender XDR has saved our security team approximately two hours per day. Automation is improving steadily, allowing us to automate audit file processing and scheduling. This provides us with continuous insight into our environment. The main page offers a high-level overview of current activity, enabling us to quickly identify any anomalies. Our security team can then address these anomalies promptly.

The threat intelligence is excellent. Email collaboration is very good. Device protection is useful. Overall, 90 percent of Microsoft Defender XDR is used weekly, primarily for email collaboration.

Advanced attacks could use an improvement.

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

I would rate the stability of Microsoft Defender XDR a nine out of ten.

Microsoft Defender XDR is scalable and we are planning to increase the usage.

The Microsoft technical support I used in the past was quite good. They were typically responsive and efficient, providing solutions quickly. However, I haven't needed their assistance in the last year, so I can't offer an updated assessment.

Our past experience includes Sophos, Check Point, and ESET. We briefly utilized SentinelOne as well, but ultimately opted for Microsoft Defender XDR. We had Defender included in our purchases but it wasn't being utilized fully until I fine-tuned and set it up to work more efficiently.

I would rate Microsoft Defender XDR an eight out of ten.

We require three people for maintenance.

We have Microsoft Defender XDR deployed across multiple locations, roles, and teams.

Before implementing Microsoft Defender XDR, ensure that all the features will be utilized otherwise it is more cost-effective to go with a smaller package that includes only the features needed by the organization.

Extended XDR expands threat protection across endpoints, email, identities, and cloud environments.

Microsoft Defender XDR provides strong identity protection with comprehensive insights into risky user behavior and potential indicators of compromise. It includes capabilities for monitoring Active Directory against attacks and threats, making it a broad and deep solution for identity security.

Improving scalability, especially for very large tenants, could be beneficial for Microsoft Defender XDR. Additionally, enhancing the privilege access management capability would make it a better solution overall.

I have been using Microsoft Defender XDR for about a year and a half.

Microsoft Defender XDR is very stable. I would rate the stability as a 10 out of 10.

I would rate the scalability of the product as a 10 out of 10.

Microsoft's customer support for Defender XDR is generally very good and I would rate it at around an eight out of ten. Larger customers like us, especially those partially owned by Microsoft, tend to receive excellent support. However, smaller organizations may not experience the same level of support.

Positive

Microsoft Defender XDR is typically deployed at the organizational level across multiple locations and departments. Maintenance is required, and the number of people needed depends on the organization's size and complexity. It could range from a large team for a big organization to just a few individuals for smaller ones.

Microsoft Defender XDR is expensive, especially for the full suite functionality. However, when compared to buying multiple-point solutions separately, it may be comparable in price. Overall, it is competitive within the market, but the broad capabilities make direct cost comparisons challenging.

Clients implement this tool to address various security issues efficiently. Microsoft Defender XDR offers a unified solution for a wide range of security needs, including extended detection and response across multiple platforms like Office, endpoints, mobile, and identity.

Microsoft Defender XDR includes some identity and access management features, especially when used alongside Azure Active Directory's privileged access management capabilities.

While primarily focused on Microsoft technologies, Microsoft Defender XDR can integrate with third-party SIEM vendors and covers multiple operating systems, including macOS, iOS, Android, and Windows, through its Defender for Endpoint and Intune capabilities.

Microsoft Defender XDR is designed as an XDR solution, utilizing the Mitre ATT&CK framework to detect and correlate events across various areas of compromise. It can identify and correlate events related to advanced attacks, such as business email compromise and ransomware, affecting security operations by providing insights into the events leading up to such attacks.

When security products like antivirus and vulnerability management software are discontinued in favor of Microsoft Defender XDR and other Microsoft 365 tools, it streamlines operations but may require less manual correlation of security events.

Some organizations might experience a 10-20% cost reduction with Microsoft Defender XDR, but for me, the main goal is to improve detection and response capabilities, not just save money. It is about adapting to the evolving threat landscape rather than focusing solely on cost savings.

Microsoft Defender XDR has saved time for our security team, making our operations more efficient.

For those evaluating Microsoft Defender XDR, my advice is to understand your requirements and map them to the appropriate licensing capabilities. It is not a one-time project but an ongoing process, so plan for continuous improvement of your security posture.

Overall, I would rate Microsoft Defender XDR as an 8 out of 10.

I work at a SOC, and we use Microsoft XDR to provide 24/7 monitoring for our clients. We use it to monitor all types of incidents, including attacks on endpoints and email-related threats. It's integrated with other Microsoft solutions.

I like how Microsoft XDR and the other Microsoft products are integrated into a single unified security stack covering identity access management, endpoint protection, email, cloud applications, etc. The Kubernetes security feature hasn't been released yet, but we're looking forward to that. I'm just focusing on that because it will be a game-changer.

The integrated identity and access management is helpful because sometimes you don't have the information you need inside XDR, so you can go to Entra for more details.

XDR can stop advanced attacks like ransomware and BEC attacks. It also has an AI-assisted automated feature that cuts off access to persistent attacks. This feature disrupts the attack by disabling user access. A person needs to analyze if the response is correct and reject or approve. 

Through integration with Microsoft Lighthouse, we can manage multiple tenants on one screen, and prioritize which areas of the environment to address first. Sometimes, one tenant may be inaccessible to you. It will show an error, but then it will start working again automatically. 

Because of the training model, Defender XDR's automatic response sometimes blocks legitimate users and activities. Also, the UI sometimes responds slowly. 

I've been working with Defender XDR for the last six months.

I rate Defender XDR 8 out of 10 for stability. 

Defender XDR is scalable. 

We had a problem once getting a feature to work correctly after an update. We contacted Microsoft, and it took about 2 or 3 days to resolve.

I previously used QRadar and Splunk

Deployment is easy. It requires some maintenance on the Microsoft side. 

I rate Defender XDR 9 out of 10. I would recommend Defender. It's easier to use than other products I've worked with, such as Splunk and QRadar.

We are using Microsoft Defender XDR for our endpoint, desktop, and laptop protection.

Microsoft Defender can extend its protection to the third-party applications we use, which is helpful.

Microsoft Defender XDR not only helps stop malware attacks but also offers advanced attack prevention features to safeguard against sophisticated threats.

Our environment is multi-tenant, and Microsoft Defender XDR offers seamless integration. Its ability to respond to threats across the multi-tenants is good.

It helps our security team by automating tasks, providing detailed reports, safeguarding our systems, and enabling historical analysis.

It has helped to reduce some of our costs by almost $10,000 per month.

Microsoft Defender XDR is easy to manage, saving our security team time.

Scanning, vulnerability reporting, and the dashboard are the most valuable features.

While the XDR platform offers valuable functionalities, it falls short of other solutions in its ability to deliver a cohesive identity experience. To address this limitation, integrating MDR as part of the XDR experience and incorporating the latest advancements into Microsoft Defender XDR are crucial steps.

I have been using Microsoft Defender XDR for over three years.

Microsoft Defender XDR is stable.

We can scale up with Microsoft Defender XDR with no problems.

We have a dedicated account manager who handles our support requests. We submit our requests through a ticketing system, and they respond promptly.

Positive

We also use CrowdStrike. Both have advanced capabilities and are easy to manage. We have them integrated with multiple tenants but for different products. 

The initial deployment was straightforward and took one to two days to complete.

While Microsoft Defender XDR carries a higher cost, its ease of use compared to Defender may justify the investment.

Although I would rate Microsoft Defender XDR eight out of ten, its visibility suffers when used with third-party applications and non-Azure cloud platforms.

While the implementation itself is straightforward, troubleshooting, log creation, and monitoring can be challenging. This solution may be suitable for Microsoft-centric environments, but its visibility suffers in scenarios with multiple third-party solutions or hybrid deployments.

We use the standard Microsoft services and solutions for our entire IT infrastructure, so we leverage most 365 Defender services, including Sentinel, Defender for Identity, Defender for Endpoint, Defender for Cloud, Defender for Cloud Apps, and Defender for O365. We use all those solutions to secure our IT infrastructure and environments.

We deliver Microsoft services to users worldwide, including SharePoint and Exchange Online. Gmail is the one minor exception where we do something slightly different. 365 Defender currently covers 5,000 endpoints and between 10,000 to 15,000 identities. There are more identities than endpoints because we don't give everyone a company laptop. 

A larger organization absorbed my company that moved to Microsoft security products a little while ago, so it was natural to do the same at my company. The biggest benefit of going with Microsoft is that it's a huge company with lots of resources to put into security.

Most devices use the Microsoft's operating system and products these days. They get a lot of data from all those users, which helps them stay ahead of the competition. They process a few billion security-related signals daily, helping them deliver a better solution to us.

Introducing 365 Defender and Sentinel was the best decision we ever made. Many organizations have most of these components in place but aren't effectively leveraging them. 

They might be using a managed services provider that forces them only to use products from their partners. Still, they have an enterprise license with Microsoft that includes Microsoft Defender for Endpoint, which is part of the 365 solution. I think it makes more sense for people to use Microsoft security solutions too.

We can automate security tasks to a degree. There are several automation options, but it depends on the definitions of analytics rules, queries, etc. Microsoft provides many of those in its out-of-the-box catalog with many additional third-party queries that you can use. You can fully automate things as soon as you have your queries defined. Getting there might be a little difficult. 

Microsoft 365 Defender saved me from looking at multiple dashboards. There are still separate dashboards for Sentinel and 365 Defender, but the same alerts and incidents are generated on both consoles. The only difference is that 365 Defender won't show you anything you've customized on Sentinel. 

There is a separate Microsoft-specific intelligence dashboard that Microsoft keeps up to date. As soon as there is a specific threat that may affect our organization, it shows up on the dashboard, and we can see the sources of the attack, the path, and all the other information you need. It's useful, but I don't think our security operations center is using it. They only rely on third-party threat intelligence resources. 

We've saved time using 365 Defender because rolling it out is easy. The hardest thing is pushing it out to all the devices you are managing. Using a third-party device management solution might be slightly more complicated, but it's straightforward within the Microsoft ecosystem. 

I'm not sure how much money we've saved overall, but they previously used McAfee EDR for antivirus, which was costly. Most of our existing solutions are Microsoft, so we were already entitled to use Microsoft Defender for Endpoint. We weren't using Microsoft security solutions because someone decided they preferred McAfee many years ago. 

The McAfee contact was around a few million, and the full Microsoft enterprise license was also a few million. Using the security solutions bundled with the Microsoft license probably cut our costs in half.

It's hard to say how much our detection and response time decreased because we didn't have a comparable solution. Instead of going to a portal for McAfee or making Splunk ingest all kinds of profiles, we could dump all the data into a more analytical tool to get all these alerts.

Having a single pane of glass for all Microsoft security services makes everything much easier. A security analyst can go to a single portal and see everything in one view. The integration of everything into one portal is a huge benefit. 

Defender provides a lot of detailed information about your environment. It may be challenging for people without much experience to get the data they need because it can also be overwhelming. At the end of the day, Defender gives you almost all the information you need for anything you want to do, and Microsoft is working to extend that further. Some areas may not be fully integrated into 365 Defender yet.

There's also a vulnerability management feature. It installs an agent on all your devices to check where you're vulnerable, so you can resolve the issue. Once you get hit by an attack, you can disrupt the attack using an advanced AI.  

We use all of the Microsoft security solutions. They do an excellent job of making it simple to integrate the security features. It's easy if you have a little experience, and there is a lot of documentation if you are entirely new. 

The various Microsoft solutions work seamlessly together, especially the Sentinel part. Attack disruption is almost fully automated.

Sentinel can ingest data from our entire ecosystem with some additional work. Technically, you could ingest anything. It would be easier if there were an out-of-the-box way to integrate it, which already exists for many components. However, several third-party products do not have out-of-the-box connectivity, so you may need to do some fairly complex work. On the other hand, it is relatively simple to ingest data from most big-name products.

Sentinel enables us to investigate and respond to threats from one place, which is essential because IT environments are increasingly complex. There are so many servers, cloud services, applications, etc. Using multiple portals to view security incidents doesn't work anymore. 

You still need to configure Sentinel to ingest data from other third-party solutions, but much of the data is readily available if you primarily use Microsoft products. There's a lot of overlap between Defender and Sentinel, but as soon as you go outside the Microsoft domain, you must start using Sentinel. 

Sentinel is comprehensive. It stacks up well against some of the other big names in the SIEM space. Microsoft plans to add even more advanced features like behavioral analytics. AI is a huge topic right now, and Microsoft is ahead of the curve compared to other solutions in the security quadrant.

It already integrates natively with the Microsoft ecosystem, but there is still room for a minor improvement in third-party integration. Another issue is that the portal is sometimes less intuitive than you would like. That's probably because they're consolidating various security products, and there are a few legacy things left over that complicate matters in some cases. 

Still, if you gave someone who works in security access for the first time, that person would be impressed and wouldn't have any specific complaints. You only start to notice a few small things once you used them for a while, but nothing is significant. 

Microsoft 365 Defender combines several Microsoft solutions, and I used the component solutions of 365 before they were consolidated into one solution. For example, I started using Defender ATP four years ago, but I've only used 365 Defender for around three years.

Overall, the stability is top-notch.

I haven't seen any limits to 365 Defender's scalability. I don't know if you would have issues once you start adding 200,000 endpoints. There might be some glitches here or there. Scalability seems to be an area where Microsoft's cloud solutions excel. 

I rate Microsoft's support a four out of ten. Support is hit or miss. Microsoft wants you to buy premium support contracts. Though they call themselves professional support, it's almost like throwing questions into a black hole. You get an answer, but it's never helpful. 

If you invest in what they call "Unified Support," it's slightly better. You get good answers quite often, but it sometimes takes a long time. They should be going to the public group to discuss technical features, and they don't do that.

In some cases, their answers make no sense. I recently caught a support person making a statement I knew was incorrect, so I had to go back to somebody in the product group at Microsoft to get them to confirm. In my opinion, it's better to invest in a support partner. These companies specialize in this. They might know a fix or shortcuts to get high-level support. Their IT department may have contacts with people in Microsoft's public group, so they can get answers faster. 

Neutral

Before my company was acquired, we used a few solutions, but they also started drifting toward Microsoft in the last year. They were also shifting from third-party solutions to Microsoft solutions. They used McAfee for endpoint protection and eventually switched to Carbon Black. 

If you asked me five years ago if I would recommend a Microsoft security solution, I probably would have said "No," but they've come a long way in a short time and made a lot of investments in that area. Seven years ago, I would also have chosen something like McAfee or Carbon Black.

365 Defender is a cloud-based solution, so you don't plan and deploy the individual components like a traditional endpoint solution. You have components installed on-prem, like the firmware for endpoints, and you run Lambda for Cloud on your servers, which may be in the cloud. We also have servers hosted in a Microsoft. Our environment combines multiple things. 

I was primarily responsible for the deployment. I found it mostly straightforward, but I also have experience and a Microsoft expert certification on many of these topics. If you've never done this before, the good news is that Microsoft documentation is excellent. It gives you all the steps that you need to take. But then it will take you a bit longer to follow the instructions. I can almost do this with my eyes closed, but it will take a lot longer for someone new to this. 

If you have some experience, you could theoretically set this up in a few days. It wouldn't be completely deployed because you may need to write several analytics rules in Sentinel, depending on your environment. The integration with Microsoft apps is one click.

I did the planning, but our IT partner did the hands-on work. The design stage took a little longer here. We discussed which features to enable and which might cause our users too many problems. That process took about two or three months. The actual deployment was finished in a few weeks. The only limiting factor was that we needed to ensure all the endpoint software was installed, which took some time. 

After the deployment, there is a little maintenance, but it's pretty automated. We need to be extra careful in some areas. Microsoft often releases new features that replace and disable existing features. Administrators may need to go into the various services and change settings. You also need to push updates to the endpoints. 

Microsoft does this automatically, but you can use a device management solution. How often do you want to do this, and how quickly? Do you want to delay specific updates to the antivirus engine for testing purposes? 

For example, Microsoft messed up about four months ago when they pushed out an update automatically to all the global endpoints. Depending on our settings, it causes certain file types to be seen as malicious and deleted from user devices. 

For example, it was deleting shortcuts. You can imagine if you came into the office on a Monday morning, and all the shortcuts have been deleted. It might make sense to test the updates to ensure they're working. You have many options to manage this, so it's flexible in that sense. It's just a matter of your organization's cybersecurity priorities. 

Microsoft customers can opt into server health notifications. You get a lot of notifications, but they may not affect your organization, and not all of them are serious. 

365 Defender can get expensive because you pay per gigabyte of data ingested. On the other hand, much of the data available in the other Microsoft security solutions are made available relatively cheaply—sometimes at cost or for free. Integrating only a limited set of third-party solutions with Sentinel would be cost-effective. It's much more affordable if companies only have Microsoft solutions. 

Data ingestion and log storage costs are relatively expensive, and you also need to consider the labor investments in fine-tuning all the analytics rules, etc. However, those costs will be similar to any product.

Microsoft licensing is highly complex, so you must carefully pick the license you need. People tend to choose the cheapest license or take a more expensive one to ensure that all possible features they need are covered. The price difference between those two options is vast. 

Some of these services are there without a license. That's problematic because the Microsoft agreements state you must license them. You might assume that you can use it. There are no restrictions in some cases, so some companies may have a problem. If Microsoft finds out, they'll get stuck with a bill because they were using something without a license. 

I rate Microsoft 365 Defender a nine out of ten. Microsoft is doing extremely well, and they plan to add a lot of new features, which is going to be exciting for many people in the security area. 

I always recommend a proof of concept, but I believe you'll be fine if most of your environment is Microsoft. These solutions also support Apple hardware, so that shouldn't be a problem either. If you're entirely using Microsoft products, I would say it's a no-brainer, especially if you are already invested in a Microsoft 365 license.

At the same time, Microsoft's licensing is extremely complicated, and there are several different licenses that go up in price quickly. You might need a licensing consultant because they know the details. You could also go in the opposite direction there. Somebody might try to sell you the most expensive Microsoft plan because they believe you need it, but you lose money if you're not using it.

Security 101 tells you, "Don't bet on a single vendor." I agree with that on a certain level because what happens if Microsoft gets compromised? But on the other hand, the native integration you get from using Microsoft security solutions is worthwhile. 

I've had this conversation with my CEO at some point. They raised the question of what would happen if Microsoft were compromised. I told them that Microsoft is one organization, but each of these product groups acts like its own startup in the sense that there is a subset of infrastructure devoted to each. If one part of Microsoft is compromised, it does not mean the whole of Microsoft is compromised. I always tell people to let go of that principle, but I understand the desire to introduce additional tooling. 

We're a small business. Defender XDR gives us a centralized security solution for monitoring our servers and some user PCs. We have around 30 machines, 10 of which are servers. 

Defender XDR saves the security team time by telling us what patches to apply. We also get preemptive notes about things that need to be done.

I like Defender XDR's reports and alerts. They give you updates about the latest hotfixes and zero-day vulnerabilities, which gives me all the information I need to maintain my servers. 

Defender's AI for identifying suspicious activity could be improved. Also, I do a lot of home updates. Maybe there is a way to set it up faster. For example, let's say that I want to automatically update seven computers, servers, etc. I wouldn't do it to a user, but maybe the server. I don't mind if the server restarts automatically.

I have used Defender XDR for a year.

Defender XDR is stable.

Defender is scalable. I haven't had any issues with that part.  

Microsoft support is good. I usually don't contact them directly. We have a support partner. If there's an issue, they can resolve it with Microsoft quickly.

We previously used Symantec antivirus. We're a small company, so switching wasn't a big deal. We switched because Symantec discontinued the solution we were using. They actually don't sell it anymore.

I wasn't involved in the decision to purchase Defender XDR. We are a small company, so we needed a vendor to support SMEs, and Microsoft caters to businesses of all sizes. We checked some other solutions but went with Defender because we're already on Azure, so the solutions complement each other.

Deploying Defender XDR was easy. Our external security guy handled most of the settings and onboarding, and our IT guy handled a few of the problematic cases. Most of the maintenance was automatic.

I don't know the exact pricing, but I believe Defender offered the best small business solution for the price.

I rate Microsoft Defender XDR nine out of 10. I don't have experience with other XDRs that I can compare it to, but I think Defender is an excellent solution. It's fairly easy to understand and navigate, and it's a good value.

We use Defender XDR to assign roles and monitor based on the analytics report from Microsoft. 

Defender XDR has improved the organization's confidentiality. If there's a DLP violation, such as someone sharing documents inappropriately, a notification will automatically trigger. Defender stops the movement of advanced attacks. We first need to set up some independent indicators of compromise. The IOCs are connected to some attack surface reduction rules.

We get alerts if someone tries installing something on the system or adding an external hard drive. We get security recommendations from Microsoft, but our security implements them on their own. We don't use the AI feature. We see significant time savings from the alerts based on the indicators of compromise. It saves us about 10 to 15 percent.

The best feature is probably the alert generation. When I do a security reset, the other session triggers instantly from the Defender console, and I can work on it. The policies are three times, but they are also ready to install it.

The identity management feature is something we need for our use case. It wraps up the access management and XDR components, so it's not just Defender. It works well with Azure AD for access management. I didn't think I needed identity and access management in the past, but it's nice to have if you're performing a significant migration on a tight schedule. 

Defender XDR's coverage extends beyond Microsoft technologies. It covers all the endpoints of users in the organization. I can manage access to any application and system within the organization. 

Defender XDR could provide recommendations for threat-hunting queries. Some people do not know how to write an advanced threat query, so we need to spend time training them. 

We have used Defender XDR for about 15 months.

I rate Defender XDR 10 out of 10 for stability. It's a stable solution. We've had no outages. 

The scalability depends on the number of licenses you can purchase. If I want to add more endpoints or solutions from Microsoft XDR, I have to pay more. The scale depends on the pricing. 

I rate Microsoft support eight out of 10. Some cases are easy fixes, so they don't take much time, whereas some of our more complex tickets take some time.

Positive

I've also worked with Trellix. Microsoft provides better recommendations for protecting our tools, devices, and files. Trellix has XDR capabilities, too, but Microsoft's recommendations are more robust. 

Defender XDR is a SaaS solution. The deployment is ongoing because we're constantly onboarding and retiring endpoints. Microsoft handles most of the maintenance for it. It rarely requires maintenance from our end. 

Defender XDR is fairly priced and cost-effective. 

I rate Microsoft Defender XDR eight out of 10. If you want to implement this product, you should have a team who understands the product well. It's SaaS-based, so the Microsoft team is delivering everything to you. However, you still need to know the product.

We are using Microsoft Defender for Office 365 for identity and email security, safe links, etc.

It works as an antivirus, and it also works for any behavioral issues in a particular machine. It protects all the applications from any vulnerability. It works in both ways. It works for vulnerability management and also for the EDR part. Earlier, we had Qualys for vulnerability management, but Microsoft Defender takes care of both. It provides information about how vulnerable a machine is, and it also takes care of the antivirus and behavioral issues in a particular machine due to some threats or any unwanted applications installed.

It helps us manage vulnerabilities. If there are any vulnerabilities in a machine due to a lack of patches or end-of-life software installed on the machine, it gives us the report. After seeing the report, we can fix those vulnerabilities by uninstalling the vulnerable applications or by patching them.

It takes care of the antivirus part. The signatures are constantly getting updated related to new viruses. It covers any identity-related issues or device-specific issues. It covers the MITRE framework. If any threat or risk is present in our environment, it takes care of that and then tells us that these are the issues that we need to work on. After we get the alerts, we do the investigation and remediation.

It provides unified identity and access management. You can create role-based access. You can create policies based on different risk levels. You can also trigger password resets. There are a lot of capabilities that are built in. You can also create conditional access (CA) policies. If any vulnerable application is installed on a device, you do not want that device to be connected to your network, you can create conditional access policies. It will first check whether the integrity of the device is as per your organization's requirements. If it is compliant, then only that device will be allowed to connect to your network. The same goes for identity. If MFA is enabled in your environment, the users will be allowed to connect only if their accounts have MFA enabled. Otherwise, the access is blocked. You can automate such things.

It is important that identity and access management are included in Microsoft Defender rather than needing an additional solution. Nowadays, you see a lot of phishing emails and unsecure links being forwarded to user accounts. In Microsoft Defender, we have secure links and safe links. Once enabled, if any malicious link is sent to a user account, when the user clicks on a link, it immediately checks whether it is safe to access. If it is found to be malicious, it is immediately blocked. If a user mistakenly clicks on a link, the risk state is changed automatically in the web portal. If you have a conditional policy in place, the access is blocked for that user. Even if the attackers have access, they will not be able to do anything. In today's scenario, it is pretty important to have these in place.

As of now, the integration part is pretty limited to Microsoft products. However, by using Sentinel, which is a SIEM solution, you can integrate other products.

It stops the lateral movement of advanced attacks like ransomware or business email compromise. You can create lateral movement policies, and you also can create high-risk users or high-risk devices. You can have customized policies for them. You can create different policies, and the alerts triggered from those devices or users are put into high severity so that you can take immediate action.

You get the telemetry of any attack observed by Microsoft Defender. You can see everything from the starting point till the remediation steps automatically taken by Microsoft Defender. The investigations can be found easily. They are pretty detailed. Everything is there in the portal.

It has the ability to adapt to evolving threats. Threat intelligence is embedded in the portal itself for new threats, technologies, ransomware, or malware. All the latest threats are automatically handled by Microsoft Defender. Remediation is also automatically available.

It saves time. There is automatic remediation, and there are playbooks that you can configure. You can automate the remediation steps that you have already tried on a particular machine. If you want to suppress some of the alerts, you can create suppression rules so that your team does not spend time investigating them. Playbooks, automatic remediation, and suppression of similar alerts save a lot of time.

Vulnerability management is valuable. We had a different product for vulnerability management. We were using Qualys for that, but after we got Microsoft Defender, we also got the vulnerability management part. It is embedded in the portal itself. We do not have to look into another solution or tool. We did not have to install any additional sensor which reduces the overhead and does not affect the machine's capability. With the same sensor, we get the vulnerability report and threat report. We also get to know any risks and issues related to malware and other things.

The portal is quite user-friendly. There is integration with Office, Intune, and other products from the same portal. From there, we can see which policies are installed on a particular machine. We also can manage devices, groups, and tagging. For a different set of teams or departments, we can create different device groups. Based on the teams and their work portfolio, we can create different policies. It is quite handy, whereas with the Qualys solution, the portal was quite cluttered. To find a particular option, we had to look at many options, whereas Microsoft Defender is quite user-friendly.

We are also getting all the reports by using the same sensor. It is light on the machines as well. It consumes less resources than other solutions available in the market.

It is evolving. We are seeing new advancements and integrations. They have integrated Copilot, so going forward, we can take the AI advantage. It will be quite easy for us to run any queries. These are the advantages that I see in Microsoft Defender in comparison to others.

The patching capability should be there. Patching is something that you cannot do even though you see the vulnerabilities present in your environment. For patching, you have to depend on another solution.

Other than that, there are still limitations in creating device groups. You can create tags, but these tags are based on limited options. There are only a few categories based on which you can create a tag or device group. If there are other conditions that you want to put, such as creating a group based on the application installed on a particular machine, you cannot do that. There are some shortcomings. Also, if you want to whitelist a particular application for a set of groups, you cannot do that. We had an incident where we wanted to whitelist a particular application that was getting blocked by Microsoft Defender, but we were not able to create those groups. We were not able to whitelist the application for some of the devices. We had to whitelist it for the whole environment, which we did not want to do.

It only has pre-built dashboards. You cannot create customized dashboards. They have a set of dashboards, but they are not customizable.

We can create reports using KQL, but it is hard to create customized reports using KQL. You get a CSV, but you need to use Power BI or another reporting product to create the report. The other products available in the market give you customized dashboards, customized reporting, and customized workflows. This is pending in Microsoft Defender.

I have been working with this solution for 1.5 years.

It is a Microsoft product. It is similar to any other Microsoft product in terms of stability. They do change the name and other functionalities, but it is pretty much similar to any other Microsoft product.

It is pretty scalable. It does not stop you anywhere.

I am working in an MNC. We have more than 6,000 people.

It depends upon the license that you have. They have a different set of licenses based on which you get support. It depends on the support packages you have purchased.

It is very easy to raise a request. They have a portal. From there, you can create a ticket by email or by chat. The response is based on the support package that you have. If you have premium support, you can get a response in minutes. 

In my previous organization, I worked with Palo Alto XDR. In this organization, we had McAfee, which is a signature-based solution. Microsoft Defender is more advanced than McAfee. It is EDR-based, whereas McAfree was signature-based. It was based on the signatures related to a particular threat or virus. It was handling threat prevention, but behavioral analysis and other functionalities that you see in EDRs were not there. We wanted to move to a behavioral-based antivirus solution. That is why we opted for Microsoft Defender.

Microsoft Defender also enabled us to discontinue the Qualys solution. It has many capabilities related to vulnerability management. They are available out of the box, but patching is something that is missing. For patching, you need to use Intune, whereas, in Qualys, you can also do patching, so patching is something that is missing in Microsoft Defender. However, Microsoft Defender is very good for the assessment of vulnerabilities.

You also get visibility of the devices that are still not onboarded to Microsoft Defender. You have something called Device Discovery in Microsoft Defender. Once enabled, you can get details of all the machines that still do not have Defender, whereas, in Qualys, you have to create customized or scheduled scans of your network. They then run on a periodic basis, but that is not the case with Microsoft Defender. It is on a real-time basis. The Microsoft Defender client continuously does the scanning, and you get visibility into all the machines on your network that still do not have Microsoft Defender onboarded. However, you cannot do patching with Microsoft Defender.

Microsoft Defender can save costs. Qualys is pretty expensive. Microsoft Defender does vulnerability management out of the box, so if you do not want to do patching and you have another solution for patching, you can save costs. It also has out-of-the-box functionality for identity protection.

It is deployed on a public cloud. If you do not have people in your team who know about this product, Microsoft can give you a vendor to help with deployment, creating the policies, etc.

Overall, it is pretty straightforward because Microsoft Defender is enabled on all Windows machines. All you need to do is to activate the sensor that is already installed. The installation process is not much, but if you want somebody to help you, Microsoft can help you with a list of vendors at a particular location. The vendor can help you with configuring the policies and activating different licenses.

Documentation is available on the Microsoft portal to help you create policies and go forward as per your environment.

We took help from somebody for implementation.

It does not require a lot of people because it is a cloud solution and the sensor is already available in the machine itself. It does not require a lot of manpower to get started with Microsoft Defender and do a migration. However, it also depends on how big your organization is. If it is an MNC with a presence in multiple countries, you might need at least one person per region. If any hands-on support is required on a client machine, you can do troubleshooting remotely or provide on-site support. If you have only one site, you do not need much manpower. A single person can do it.

Its maintenance is similar to any other solution. If you are changing any policy, you have to test them before putting them into production. Apart from that, it does not require anything. The Defender updates are automatically available. You can push them through your patching solution. Its maintenance is not hard.

Every organization has different requirements. In my previous organization, we opted for Palo Alto even though we had Defender and CrowdStrike. CrowdStrike is also a best-in-class solution, but we opted for Palo Alto because it was giving something that was a requirement. In that organization, we also wanted to do some management. We wanted to run some scripts through our XDR solution. CrowdStrike had some limitations. We also wanted to do a console login for a particular machine. CrowdStrike gave that functionality, but it was pretty limited, whereas, in Palo Alto, it was limitless. We could straightaway see the files present on a machine by using the console view. We could run a different set of queries. It did not matter whether we were running a PowerShell script, a Python script, or any other language script because the compiler was embedded in the sensor. Palo Alto met the needs of that company. For the use cases, it was the best fit.

In my current organization, the use cases are different. We only wanted an EDR solution. Also, because most of the products in our environment are from Microsoft, the integration with them was pretty easy. That is why we opted for Microsoft Defender. An organization should look at its use cases and then decide on an EDR/XDR solution.

Comparing Microsoft Defender's EDR capabilities with other solutions, I would recommend going for another solution available in the market. I would rate it a 6 out of 10 because there are a lot of things that are available in other solutions, such as doing a remote of a particular machine and running other language scripts. Other solutions are also better in terms of the isolation of a particular device, removal from the isolation, and granularity of security control. I am not comparing it with others for vulnerability management because Palo Alto or CrowdStrike do not do that. If there are any vulnerabilities and you want to fix them, you have to do all the work.
