We are using it as the antivirus as well as the malware protection.
Its files and folder protection ensures no changes can made to endpoint folders and files without the user being aware
Pros and Cons
- "It is quite stable. We have not had any cases, i.e., viruses, that would require a reboot, etc. We have never had a situation where we needed to reinstall the tools as a result of the Defender application or a feature being corrupt."
- "The folders and files protection are its most valuable features. These have been valuable because of the increase in ransomware attacks. With these two features, I can ensure that no changes have been made to our system or endpoint folders and files without the user being aware."
- "We have not had any attacks, in terms of viruses, worms, or ransomware, in the last three years."
- "I wish they would extend the use of the Security Central portal, even for the free option of Defender. Because, as companies grow, it is labor intensive to manage the AV and detection part of it. For companies already subscribed to Office 365, I think this would be a good enhancement."
- "I wish they would extend the use of the Security Central portal, even for the free option of Defender."
What is our primary use case?
How has it helped my organization?
We have not had any attacks, in terms of viruses, worms, or ransomware, in the last three years.
The impact of the solution has been minimal. Employees can work with any interruptions.
What is most valuable?
The folders and files protection are its most valuable features. These have been valuable because of the increase in ransomware attacks. With these two features, I can ensure that no changes have been made to our system or endpoint folders and files without the user being aware.
What needs improvement?
I wish they would extend the use of the Security Central portal, even for the free option of Defender. Because, as companies grow, it is labor intensive to manage the AV and detection part of it. For companies already subscribed to Office 365, I think this would be a good enhancement.

Microsoft Defender for Endpoint
August 2026
Learn what your peers think about Microsoft Defender for Endpoint. Get advice and tips from experienced pros sharing their opinions. Updated: August 2026.
912,006 professionals have used our research since 2012.
For how long have I used the solution?
I have been using it for three years.
What do I think about the stability of the solution?
It is quite stable. We have not had any cases, i.e., viruses, that would require a reboot, etc. We have never had a situation where we needed to reinstall the tools as a result of the Defender application or a feature being corrupt.
Four IT support technicians are responsible for administrating Microsoft Defender in our organization. They make sure that upgrades and updates are done in a good timeframe.
What do I think about the scalability of the solution?
Its scalability is good enough. As long as you deploy the OS, you will keep on deploying Microsoft Defender automatically. This is a good option.
We have about 375 endpoints.
How are customer service and support?
I have never used their support.
Which solution did I use previously and why did I switch?
Before Microsoft Defender, we were using Bitdefender. Before Bitdefender, we were using McAfee Symantec.
We switched to Microsoft Defender because there was a change of ownership for the company in 2017.
We went for Microsoft Defender once we were informed that it would be part of our Office 365 package. So, we combined the licensing for the OS with Office 365. Yeah. We thought it was a good bargain.
How was the initial setup?
The initial setup was straightforward.
The deployment takes a maximum of half an hour.
What was our ROI?
We have seen ROI. Most of the other competing alternatives will cost up to around $30 per user device. We average 400 devices. Therefore, the amount that we save each year is 400 times $30.
What's my experience with pricing, setup cost, and licensing?
We have been using the free version.
What other advice do I have?
Microsoft Defender is good enough as long as you ensure the environment is well-patched and secure, then even the free option will be sufficient to take care of the entire ground.
We are not looking to increase usage at the moment because of the underlying economic situation.
I would rate this solution as nine out of 10.
Which deployment model are you using for this solution?
On-premises

Integrates well with Microsoft technologies, but needs direct integration for USB control
Pros and Cons
- "It depends on the licensing. Most of the customers have got at least a 365 E3 license, and they can use most of the features of Windows 10 Defender. So, anyone who has got an enterprise license can start using those features. Some of the customers have got E5 licenses, and they can use all advanced features. Customers with E5 licenses use the advanced site protection (ATP) features and web content filtering without going via a proxy, which gives the benefit of replacing the proxy. They can get the benefit of MCAS and integration with Intune and the endpoint manager. It is a kind of single platform for all 365 technologies. It helps customers in managing everything through a unified portal."
- "Our clients are definitely seeing an ROI."
- "I would like Microsoft to have some kind of direct integration for USB controls. They have GPO and other controls to control the access of the USB drives on devices, but if there is something that can be directly implemented into the portal, it would be good. There should be a way to control via a cloud portal or something like that in a dynamic way. USB control for data exfiltration would be a good feature to implement. Currently, there are ways to do it, but it involves too many different things. You have to implement it via GPOs and other stuff, and then you move or copy those big files via Defender ATP. If there is a simple way of implementing those features, it would be great."
- "What I've heard from the customers is that the anti-malware engine is not up to date, so sometimes it may not detect such threats."
What is our primary use case?
Our clients use it for antivirus and anti-malware purposes.
What is most valuable?
It depends on the licensing. Most of the customers have got at least a 365 E3 license, and they can use most of the features of Windows 10 Defender. So, anyone who has got an enterprise license can start using those features. Some of the customers have got E5 licenses, and they can use all advanced features. Customers with E5 licenses use the advanced site protection (ATP) features and web content filtering without going via a proxy, which gives the benefit of replacing the proxy. They can get the benefit of MCAS and integration with Intune and the endpoint manager. It is a kind of single platform for all 365 technologies. It helps customers in managing everything through a unified portal.
Normally, we implement the attack surface reduction (ASR) rules and exploit protections. We also use Microsoft Defender Application Guard and ad blocker. Instead of using the application control list, we use the ad blocker at most of the places.
What needs improvement?
What I've heard from the customers is that the anti-malware engine is not up to date. So, sometimes, it may not detect such threats. I, however, haven't got any data to show for this.
Its licensing can be better. Currently, customers with the E3 license cannot use many features, and they would like those features to be available. With Windows 10 E5, Microsoft is phasing out all the functionality. They have also made a lot of changes recently where you can also buy add-ons for Defender ATP, but for Office 365, ADT, and other stuff, you still require E5 licensing. If they can improve its licensing, it would definitely be helpful in implementing the features from the security point of view. E5 definitely has more features from the security point of view.
I would like Microsoft to have some kind of direct integration for USB controls. They have GPO and other controls to control the access of the USB drives on devices, but if there is something that can be directly implemented into the portal, it would be good. There should be a way to control via a cloud portal or something like that in a dynamic way. USB control for data exfiltration would be a good feature to implement. Currently, there are ways to do it, but it involves too many different things. You have to implement it via GPOs and other stuff, and then you move or copy those big files via Defender ATP. If there is a simple way of implementing those features, it would be great.
For how long have I used the solution?
We have been recommending Defender to customers for Windows 10 and helping them in implementing it for two years.
What do I think about the stability of the solution?
It is okay in terms of stability. I haven't seen any issues. Even if you go for a third-party vendor as your primary anti-malware software, you can get the benefit of Defender in a passive mode.
I am an Azure engineer, and I work with an architect to design the solutions. I'm not a security person, and I don't know whether it catches all the new malware that comes into the IT world, and how quickly it gets updated because it is not my area of work as I'm not an SEC OP admin. I have read a few articles mentioning that the engine might only be 80% or 90% up to date. Obviously, no engine is 100% up to date, but it is still a little bit behind some of the third-party vendors.
How are customer service and technical support?
We haven't used their support much, but one of my colleagues has had some problems, and I think he didn't get good support from Microsoft. So, obviously, it depends on what kind of support engineer you have been assigned. Sometimes, it can be difficult. It is not only applicable to Defender; it could be with any of the products.
How was the initial setup?
While implementing the ASR rules and other things, if you don't put it in the audit mode and don't do proper discovery, then it can definitely break lots of applications. You need to adhere to the implementation guidelines for ASR rules. So, proper analysis definitely needs to be done before implementing those rules because it can affect the business functionality.
Its deployment can take from few weeks to months depending on the size of the organization. In terms of the implementation strategy, we start with the pilot key users, and we deploy those policies. We also deploy ASR rules and other exploit protection rules in the audit mode, instead of directly enabling them. We then monitor the resources in terms of what can be blocked or what can get impacted by those rules. After that, we work with the users to implement it and see whether it breaks anything. If it breaks, then we look at the solutions. After we are happy with all those solutions and we know that enabling it won't break anything on a business side, we just roll it out.
What was our ROI?
Our clients are definitely seeing an ROI. Some of the clients have already got the licenses, and they can use lots of features of their Defender ATP. They are basically saving the cost of not going with a third-party solution.
Some of the clients who already had another third-party solution are also moving to Defender ATP because they already have the licenses, and they can save the cost on those. One of our clients is using ESET. They have the ESET standard version, so they are not getting any of the other features. They already have an E5 license to use all Defender ATP features. So, obviously, it would be beneficial for them to go with Defender ATP.
Which other solutions did I evaluate?
We did a little bit of comparison with Sophos. Sophos also offers cloud and network protection, but it would be an extra cost to buy it if you already have a license of Defender ATP. With Sophos, the USB features are a part of the cloud solution. So, you can configure USB restrictions and other things in the Sophos portal. With Defender, you will have to implement the USB security features via GPO or something else.
What other advice do I have?
I would definitely recommend others to go with Defender ATP if they have got the licenses because it can give them a wide range of security controls. It is integrated with Office portals and Microsoft monitoring systems, so they get the sensors from different places. We haven't come across any security threats yet. From the point of view of its theory, implementation, and architecture, Defender ATP and other ATP integrations would definitely help customers in controlling their organization and implementing the best security rules and policies.
It hasn't affected the user experience much for our customers. Customers only see the notification pop up saying that Defender hasn't found anything and things like that.
I would rate Microsoft Defender for Endpoint a seven out of 10.

Microsoft Defender for Endpoint

Head, Information Security & Network Operations at a consumer goods company with 10,001+ employees
Nice interface and good reporting, but the alerts need to be more timely
Pros and Cons
- "This is not an inventory solution, but it helps you take count of how many workstations you have, as well as what software is installed on each of them."
- "We saw a return on our investment within the first two years."
- "The alerting is something that needs to be improved. Alerts need to be sent immediately because as it is now, you see some of them without delay and others arrive perhaps 30 minutes later, and it leaves important gaps in terms of information gathering."
What is our primary use case?
We combine Microsoft Defender with Advanced Threat Protection to manage, isolate, and scan our laptops and workstations for security threats. We have a dashboard that is embedded into Office 365 and it allows us to remotely scan for viruses and malware, so we don’t have to have the laptop present.
How has it helped my organization?
Using this product helps with device inventory. This is not an inventory solution, but it helps you take count of how many workstations you have, as well as what software is installed on each of them. It is important because any software installed on a workstation may be vulnerable to parts of the internet.
Microsoft Defender has features that have helped to add layers to our security posture. The most important of these features is visibility and the provision of detailed alerts. It correlates the data and using this information, I can identify a threat and see if any other workstation in the environment has been affected by it.
Using this product has not negatively affected our user experience. It is just like using Windows 10.
What is most valuable?
The GUI is very nice.
The reporting capabilities are fantastic.
In the future, I would like to have the ability to patch using this product. Specifically, in an enterprise environment, it would be very good if you could patch the workstations remotely.
What needs improvement?
The alerting is something that needs to be improved. Alerts need to be sent immediately because as it is now, you see some of them without delay and others arrive perhaps 30 minutes later, and it leaves important gaps in terms of information gathering.
For how long have I used the solution?
I have been working with Microsoft Defender Antivirus since it first came out, at least seven or eight years ago.
What do I think about the stability of the solution?
With respect to the stability of the product line, Microsoft has many products that do almost the same thing. The question becomes which one you want to use. This is a good product but at the same time, after a while, you don't know if it is the next one that Microsoft is going to stop releasing because of other products that practically do the same thing.
What do I think about the scalability of the solution?
Microsoft Defender is very scalable and there is a lot of room to expand and add extra layers. We have 2,500 endpoints and we plan to expand; however, we are thinking about using the Microsoft Endpoint Manager in place of it.
Once the decision is made to stay with this product or instead adopt Endpoint Manager, we will expand to cover 6,000 endpoints.
How are customer service and technical support?
I have not been in contact with technical support.
Which solution did I use previously and why did I switch?
Prior to Microsoft Defender, we tried quite a few different products from vendors such as Kaspersky and McAfee. One of the major reasons that we adopted Defender is because of the advantage that Microsoft owns the platform, Windows 10. As they have developed the operating system, it is believed that they understand how to guard it much better against a third party. An attacker has to learn a lot about Windows 10.
Another reason we selected Defender is the frequency of updates. Every other time that Windows is updated, Defender is updated. Again, this is because it is owned by Microsoft and exists on its platform.
We also use Microsoft ATP and we are currently looking at Microsoft Endpoint Manager.
How was the initial setup?
The initial setup is straightforward. Basically, once you have the competency with the product, it is straightforward and there are no surprises. It is not rocket science.
This product is built into the Windows 10 image that we install. As you roll out Windows 10, it is already set up and pre-configured, so there is no additional work required.
What was our ROI?
We saw a return on our investment within the first two years.
If I quantify the effort used for the setup and compare it with the pricing of the previous solution, value for the money was realized during the second year.
What's my experience with pricing, setup cost, and licensing?
We have an enterprise agreement so from my perspective, this is a product that ships with Windows and it is not priced standalone. It comes together with the other Microsoft products that we buy.
Which other solutions did I evaluate?
When we evaluated Kaspersky and McAfee, we found the scalability was better for Microsoft. You can do in-place upgrades of the endpoints with Defender but for the others, you would have to re-install the upgraded agents on the workstation. This takes a lot of time and it is not productive.
We are currently evaluating Microsoft Endpoint Manager by comparing the differences between it and Microsoft Defender. This is being done in advance of expanding our usage.
What other advice do I have?
My advice for anybody who is implementing this product is to first analyze their critical assets to have an understanding of what they are. Then, decide if they want a scalable solution. New threats are coming in every month and the way this is going, Microsoft is learning lessons from networks that have been compromised. With this information, they give updates and patches to everybody. In support of this product, you have to consider the patching, consider the visibility that it gives, and then consider the critical assets it is protecting.
I would rate this solution a seven out of ten.
Which deployment model are you using for this solution?
On-premises

IT Manager at SAI Systems
Reduces admin overhead and allows us to define and roll out policies from a central console
Pros and Cons
- "The best part is that it is built into Windows, whether it is a server base or a desktop base, which gives more control over the operating system. Because Defender, the operating system, and the Office solution are by Microsoft, everything is working like hand-in-glove. Its administrative overhead is less because a desktop user has already got some experience of how to handle a Microsoft Defender notification or administer it."
- "This is the best feature of having OneDrive backup on the fly and recovery on the fly."
- "Its user interface (UI) can be improved. Currently, in the console, you have to dig down for certain things. They've got many different layers to get to things instead of having it all on the surface. You have to go three folds lower to get to specific functionality or click a particular option. It would be good if we can manage the console through menus and instead of three clicks, we can do things in one click. They need to change the UI and work on it in terms of a better user experience."
What is our primary use case?
It comes inbuilt with Windows Server and Windows 10, so we are using its latest version. It is deployed centrally on all the platforms, whether it is a virtual environment, a BYOD device, or an office device. It is deployed everywhere.
All of our users are on Office 365. By default, every user is getting Office 365, and we are also incorporating this into data leak prevention. We have also enabled Azure Active Directory, so policies are deployed directly from our active directory.
How has it helped my organization?
It has reduced admin overhead. Because it comes inbuilt with Windows, we don't have to deal with the complication of using a third-party solution. We stopped using Symantec Antivirus three years ago. Previously, we had to find a person who knew how to manage Symantec Antivirus. Now, we don't have that overhead. It is also less taxing on the admins because they don't need to license an extra software every year and then deploy and manage those licenses. Everything is seamlessly managed from a central application.
Our full backup is on OneDrive. We had deployed separate storage area networks to back up important data for off-site users, not on-site users. In the current scenario of work from home, users need to establish a VPN connection to run our backup system. When they are at home, we cannot back up their systems if they don't have good connectivity. We also can't tax their broadband connections. Incorporating OneDrive as a backup solution with Windows Defender and Windows 10 has helped us immensely. We were not prepared for having people working from home because we always worked from the office, and 100% office attendance was required, but due to the pandemic, people moved to their hometowns, and we could no longer manage those systems. It became a headache for us when people used to report that their Windows got corrupted. Because they were working from home and there is a big problem of electricity in India, if electricity is not there, the systems suddenly shut down, and the registry gets corrupted. All these things are difficult to handle when you're at a remote location and you don't have your eyes and hands on that particular location. In such times, Windows Defender became a very big helping hand in managing the recoveries of such systems. The backups managed from OneDrive were very helpful. It has saved hundreds of hours of restoring the system in case something goes wrong. There was an instance where a user opened a spam message, and a ransomware attack was done on that system. Because the backup is managed by OneDrive, within 17 hours, this user's whole laptop was recovered without physically working on that laptop. Because of slow connectivity, it took time, but we were able to recover. This is the best feature of having OneDrive backup on the fly and recovery on the fly. These 17 hours were peanuts as compared to the data that we were able to save. This is the best selling point of having OneDrive as a backup with Windows Defender and Office 365.
What is most valuable?
The best part is that it is built into Windows, whether it is a server base or a desktop base, which gives more control over the operating system. Because Defender, the operating system, and the Office solution are by Microsoft, everything is working like hand-in-glove. Its administrative overhead is less because a desktop user has already got some experience of how to handle a Microsoft Defender notification or administer it. While working on Windows 10, every now and then, users might have seen it popping up, and they know how to do certain things. So, it is not too taxing from an administration point of view where we have to tell users what to do.
Centralizing policies and rolling everything out is done only from one console. We are able to provide restrictions based on what we want to filter, such as certain apps should not run and certain things should run. Because we are also into website development and code development, sometimes, users need to run certain software or their own build application, which is not possible to specify with an antivirus solution. With Defender, we can centrally deploy a policy where certain parts are excluded, and they can run their code in those particular parts. This is a very nice feature where we don't have to micromanage developers' PCs or exceptions.
Data leak prevention is something that our company requires, and it is incorporated in this solution. Because we are using Microsoft OneDrive, and it is easy to take the backup to OneDrive via Microsoft Defender.
It has helped in improving our security posture.
What needs improvement?
Its user interface (UI) can be improved. Currently, in the console, you have to dig down for certain things. They've got many different layers to get to things instead of having it all on the surface. You have to go three folds lower to get to specific functionality or click a particular option. It would be good if we can manage the console through menus and instead of three clicks, we can do things in one click. They need to change the UI and work on it in terms of a better user experience. For example, user management should be in one menu, license management should be in one menu, and backup management should be in one menu. Currently, if you click on a user, you will get some devices there, and some devices will be on the other menu. Its UI is complicated. In terms of functionality, everything is okay. We don't want anything to be changed in it.
For how long have I used the solution?
We have been using this solution for three years.
What do I think about the stability of the solution?
It is highly stable. We don't even have to look into it to see if it has stopped working, or whether it is doing its job well or not. We have around 500 devices in our organization, and all devices do the regular login with the logs. It is immensely stable.
What do I think about the scalability of the solution?
Its scalability is immense. There is no device, user, or policy limit. You install a device, and it is automatically configured because the policy is deployed from the centralized policy server or active directory.
We have around 500 devices in our organization, and all devices are using it. We have all kinds of devices such as laptops, desktops, notebooks, surface devices, etc. We also have in-house virtual servers on the AWS cloud and in-house physical servers. We also recommend enabling it for our client servers, and we configure policies for them.
Every person in our organization is using this solution. We have approximately 380 users. Its users include everyone from a new joiner to our management president. Last year, our strength was 260, and this year we have 380 users. We are growing, and by 2022, we should have more than 600 users. We are growing in a very good manner, and a group target is there. We are definitely going to grow.
How are customer service and technical support?
We have been using Microsoft products since the commencement of Windows 95. We have rarely used their support because they make their products in a way that makes them easy to use. Sometimes, there are flaws and issues, and because we are also a Microsoft Partner, we get support on priority. They take a case at the level where they think it will be resolved, and if someone is not able to resolve it, it automatically gets escalated.
We mostly use our in-house support. In the past 20 years, we have used their support twice. When I used their support last time around four to five years ago, they were really very helpful. They were good and very professional. I cannot comment on how their support is now with the current pandemic and people not working from the office.
Which solution did I use previously and why did I switch?
We were using Symantec Antivirus three years ago. When we were using Symantec Antivirus, users used to report that certain popups are there, and what should they do with them. They used to ask, "Is my system infected?" They used to panic on seeing those pop-ups. Most of them were unnecessary and would say that they need to have admin access or a particular software is trying to open a port. Because we are into development, it is a requirement of a developer to open certain ports and to make that application listen on certain ports. Such requirements were very difficult to configure in Symantec. It was difficult to make it understand that these ports are going to be used by developers, and they are going to be opened, and it is not a virus activity. Sometimes, the temporary folder of users used to get infected, and it used to give hundreds and hundreds of pop-ups. We didn't know how to close all those pop-ups in one go because they were not in a group. Imagine sitting and closing a hundred pop-ups. We had to click the Close button on each and every pop-up.
With Microsoft Defender, we can control notifications. We can tell which notifications should go to the users and which shouldn't go to the users and should be forwarded to the admin central console. In terms of user experience, users are happier with less annoyance of pop-ups that they used to get with Symantec Antivirus. They do not need to know each and everything that is going at the backend. Only the admins need to know certain things, and they should know them. With Microsoft Defender, users don't even get to know that they have an antivirus solution on their system because they never get any irritating pop-ups or notifications or slowness of the system. We configure everything from the backend, and we are managing their systems from one console, which is the biggest plus point of Microsoft Defender.
How was the initial setup?
Its initial setup is very easy. It took us just a couple of hours to deploy it on remote devices.
Our implementation strategy was to deploy group policies and manage the DLP policies from the central console.
What about the implementation team?
We did our own research, and because it was a lockdown, we had resources on our hands. We asked one of our system admins to look into the options and the policies that we need to deploy and what we need to do. He went over it for a month and trained the rest of the team. Within one and a half months, it was fully operational on each device, and my whole team was trained on it.
The whole job of its deployment was done by one person, and for maintenance, we have got a five-person team because we have 380 users across the clock and across the globe.
What was our ROI?
We have very much seen an ROI.
What's my experience with pricing, setup cost, and licensing?
Licenses depend upon what you are looking for and what kind of security do you want to implement. There are costs in addition to the standard licensing fees.
When we used to buy Symantec, we used to spend on 100 licenses. We used to spend approximately $2,700 for those many licenses, and they came in packs. To add one more license, I had to buy a pack with a minimum of 10 licenses. I had to spend on nine extra licenses because I can't get a single license, whereas when we go for Microsoft, we can get as many licenses as we want.
If I have 100 users today, and tomorrow, I have 90 users, I can release my 10 licenses next month. With any other software vendor, you buy licenses for one year, and you have to stick with that. If today you have 100 licenses, and tomorrow, you have 50, you have already paid for one year's license. You can't go back and tell them that I don't require these 50 licenses because I have lost my 50 users, but with Microsoft Defender, licensing is on a monthly basis. It gives you both options. You can go yearly and save on it, or you can go monthly. You will, again, save on it. It is very fair everywhere.
What other advice do I have?
My advice is, "Try it, and you will love it." If you go for any other product, you will have to manage everything separately, which becomes an overhead. You will have a separate console, separate licensing, and a separate vendor. You will also get a piece of software that is going to have a layer in between the operating system and your applications, whereas Defender incorporates itself onto the layer where the operating system is sitting. So, you don't tax your resources to manage a product that is already incorporated into all systems. Everybody knows how to use Windows and Defender, so the learning curve is also not there. It is very easy, and it offloads a lot of things such as tech requirements, separate licensing requirements, and separate vendor management.
I am not advising you to go ahead and discard whatever you are using. You should implement it in a test environment and see what your requirements are because the requirements will definitely impact the licensing. If your requirements are met, and then compare the time required to manage Defender versus the current solution that you are using. You should compare how many hours are you putting in managing both solutions with a different skill set. Only after such evaluation, you should deploy it.
The biggest lesson that I have learned from using this solution is to always keep it simple. Don't complicate.
I would rate Microsoft Defender Antivirus a nine out of 10. If they can make the UI more systematic, I can give it a 10 out of 10.

Analyzes behaviors and provides great visibility
Pros and Cons
- "It has Kusto Query Language (KQL), so we can use our own queries to find anything."
- "We need better support to learn about the product. Documentation is available, but we need some kind of training program so that we can get a better understanding of the product."
What is our primary use case?
We are using it only for EDR, but we have a plan to extend it to Microsoft email as well as to the cloud.
How has it helped my organization?
Within one month of using Microsoft Defender for Endpoint, we could achieve great insights.
Microsoft Defender for Endpoint is a perfect solution. We have used several EDR products, and Microsoft Defender is the best one that I have worked with. It provides great visibility. It is very transparent. We can get so many details about a particular endpoint. It is a great product. I would rate it a five out of five in terms of visibility.
It helps us to identify process-based threats in our environment, not only the signature-based ones. We are able to identify some of the threats that were not detected previously.
We get severity levels from the solution itself. Based on them, we have developed our action plan to act upon any category of incident. It helps to achieve a better SLA to attend to incidents.
I am quite interested in the vulnerability dashboard. It provides vulnerability data according to the CVE database, which helps us to prioritize vulnerabilities in our environment and address them.
Microsoft Defender for Endpoint works with Windows and Linux, so we could cover them all. It is suitable for servers as well, not only for endpoints, so we could implement it on most devices in the organization. It has probably saved us 20% of the time.
What is most valuable?
It has Kusto Query Language (KQL), so we can use our own queries to find anything.
We can get real-time updates. It is not just signature-based. It provides results based on behavior and successors. It analyzes the behavior and the process. With that, we can achieve greater results that other products do not offer.
What needs improvement?
We need better support to learn about the product. Documentation is available, but we need some kind of training program so that we can get a better understanding of the product.
For how long have I used the solution?
We switched to Microsoft Defender for Endpoint about one month ago.
What do I think about the stability of the solution?
I would rate it an eight out of ten in terms of stability.
What do I think about the scalability of the solution?
It is highly scalable. We have around 5,000 users. I would rate it a ten out of ten in terms of scalability.
Which solution did I use previously and why did I switch?
Previously, we were using a separate EDR product in our environment. We were using Sophos. Our organization moved into Microsoft 365, so we switched to Microsoft Defender for Endpoint.
We heard that it is one of the best products in the industry. We thought that we would get better results with Microsoft Defender for Endpoint. That is why we moved to Microsoft Defender for Endpoint, and we were able to achieve better results with it.
How was the initial setup?
It is a cloud deployment. It took us a few months to make the switch.
It does not require any maintenance from our end.
What other advice do I have?
Overall, I would rate Microsoft Defender for Endpoint a nine out of ten.

Automation of routine tasks makes our processes more efficient
Pros and Cons
- "It automatically detects intrusion and malware."
- "For securing access, USB security helps us block our USB ports and that ensures that users do not plug USB drives into their computers."
- "The time it takes to restore the application could be improved. It has a lot of dependencies. It's not like the Microsoft security that comes with the OS. Updating through the command prompt, most of the time, it takes some time to download some of these dependencies."
What is our primary use case?
We use it for security purposes. It provides important security for some critical systems, such as network devices.
How has it helped my organization?
For securing access, USB security helps us block our USB ports and that ensures that users do not plug USB drives into their computers.
In addition, our efficiency in the way we handle our processes has been improved because the solution automates routine tasks and helps find high-value alerts.
It has also saved us a good amount of time, something like 15 percent, while decreasing our time to detect and our time to respond, each, by 5 percent.
What is most valuable?
It automatically detects intrusion and malware.
It's also easy to use. The interface is user-friendly and the navigation is
not difficult. It is very easy to move from one hyperlink to another, to move from one solution within the platform to another solution.
And in terms of categorizing the info and the actions that need to be done, it helps you to prioritize threats. That is very important.
What needs improvement?
The time it takes to restore the application could be improved. It has a lot of dependencies. It's not like the Microsoft security that comes with the OS. Updating through the command prompt, most of the time, it takes some time to download some of these dependencies. They need to make the download of the dependencies more efficient.
For how long have I used the solution?
I have been using Microsoft Defender for Endpoint for more than five years.
What do I think about the stability of the solution?
The stability is okay.
What do I think about the scalability of the solution?
It is scalable. We use it for multiple departments, teams, and locations. We have over 5,000 users.
How are customer service and support?
I would rate Microsoft's technical support at seven out of 10, because of the time it takes them to respond. But when they finally respond, they give us complete attention and things are resolved within the SLA.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
Before Microsoft Defender for Endpoint, we were using McAfee.
What other advice do I have?
We constantly get updates from Microsoft that are light and they don't really affect us while we're working. The updates have been very helpful.
I would recommend Microsoft Defender for Endpoint.
Which deployment model are you using for this solution?
On-premises

It shows you the dangers that matter the most to your own organization and which threats you should address first to achieve the most significant improvement in your security posture
Pros and Cons
- "Defender provides useful alerts and groups them. It sends an alert to your portal if it detects any malicious activity, and you can group multiple alerts to form an incident."
- "Microsoft covers every aspect of security and the global challenges we face."
- "I rate Microsoft support seven out of ten. I had some cases a while back and told an agent my issue, and when I called the next day, I had to explain everything again to a different person, so I found it annoying to repeat myself all over."
What is our primary use case?
We use a package of Microsoft security products, including Defender for Endpoint, 365 Defender, Sentinel, and Defender for Identity. You can integrate them with a few clicks. They work together natively, and Sentinel provides advanced monitoring, so you know everything happening in your environment.
It's essential to have one space where you can manage all these solutions together because security can be complicated. It makes it that much more complex to have to navigate to a different portal for identity, email, etc. It's crucial to have a single place to manage all your security operations, so you don't have to move around.
We started with endpoint protection, where you install an agent on your client with a sensor already built in. Once you have that agent installed, the endpoint can report to the Microsoft security portal. You'll be able to see the device onboarded on the portal using some scripts, and you can monitor most of the vulnerabilities. You can also detect, respond and remedy security vulnerabilities from the portal.
We added email protection by setting policies that will analyze our email. It analyzes our links and attachments to see if there's malware attached. We move ahead to use Defender for Office 365. We also moved forward with Defender for Cloud, and the solution for our workloads, like VM, our network security group, etc. There is another one called Defender for Identity that lets us manage our on-premises and cloud identity from a single portal.
How has it helped my organization?
Many of our users are on older operating systems and browsers with vulnerabilities that harm the environment. An attacker can take advantage of those old browsers to access the infrastructure. Defender for Endpoint lets us identify those browsers with vulnerabilities and resolve the issues. We can also find processes that we didn't initiate and stop them right away.
Defender helps us prioritize threats from the security portal. It shows us the dangers that matter the most to our own organization and which threats we should address first to achieve the most significant improvement in our security posture.
We can manage Defender for Endpoint and Defender for 365 from the same integrated security portal, and it's user-friendly. Microsoft is much more user-friendly than Sophos.
Microsoft covers every aspect of security and the global challenges we face. The biggest threat today is identity and access management. If someone has access to your identity, they can access much of your technology. They have solid solutions for identity, email, and cloud. I don't think there's anything Microsoft left out. Microsoft has your security environment protected.
Sentinel enables you to ingest data from your entire ecosystem from on-premise to the cloud. It has single sign-on technology, so you can use your account from your on-prem to sign on to the cloud and vice versa. A user doesn't have to remember a lot of passwords.
Sentinel's data ingestion is essential. Security tasks can be tedious. It's great to have technology that lets you integrate all your data from different sources. You can also incorporate data from other clouds, not just Azure. You can have data from Azure and on-premise.
So far, Sentinel is one of the most comprehensive SIEMs I've seen. They have even added this XDR. Sentinel doesn't just do SIEM and SOAR. It also covers XDR. The automation is there, so you don't have to do much work. The automation helps you look at the activities behind all this data and correlate them to see the relationships. It gives you information at a glance to see if there is a relationship between these various data sources.
Defender saves us time. A task takes typically three days and could be accomplished in one day using Microsoft technology. With an on-premise network, you need to switch between portals on all your network devices, but you can achieve that from one portal. You can set policies that will block traffic to your infrastructure, so it saves time. The advanced threat protection using AI has also reduced our detection time.
We've also saved money. We previously managed the technologies on-premise, so we had to maintain the solutions ourselves. We spend less using Microsoft cloud technology because we don't need to pay for those extra features. We only need to pay for operational expenses.
We don't have to go to the affected devices when we see a security vulnerability from the portal. We can respond to those issues and resolve them using an endpoint management solution, like Intune. When we resolve a security issue, it takes a week to see the score, but we see the results immediately.
What is most valuable?
I like the security score that you can see from the portal. You can see the list of the vulnerabilities, and the security score tells you how well your organization is managing those vulnerabilities. It's a strong feature that helps improve your security operations.
Another helpful feature is the recommendations. The portal will guide you on how you can resolve those issues from your own endpoint. This feature is great if you don't have that kind of experience. It will help you understand the technology better and improve your security posture.
Defender provides useful alerts and groups them. It sends an alert to your portal if it detects any malicious activity, and you can group multiple alerts to form an incident.
What needs improvement?
I would like to see Sentinel better integrated with the rest of the security technology within one portal.
For how long have I used the solution?
I've been using Defender for more than a year.
How are customer service and support?
I rate Microsoft support seven out of ten. I had some cases a while back and told an agent my issue. When I called the next day, I had to explain everything again to a different person, so I found it annoying to repeat myself all over.
It would be helpful if they had some coordination between their support, so we don't have to repeat ourselves. They should be able to transfer your details from one agent to another.
Which solution did I use previously and why did I switch?
We previously used Sophos.
What's my experience with pricing, setup cost, and licensing?
Defender doesn't cost that much. When you use Microsoft technology, you can start with the free version and see how much the technology helps your organization solve security problems before you use the subscription. They also do this pay-as-you-go model, so you only pay when you use it.
What other advice do I have?
I rate Defender for Endpoint nine out of ten. It's great. I don't have anything negative to say about those technologies. They are serving their purpose.
Which deployment model are you using for this solution?

Threat intelligence helps against potential threats before they hit, and Sentinel is powerful for searching
Pros and Cons
- "The visibility into threats that the solution provides is pretty awesome... This is something that makes me think, "Wow, okay. If I had my own organization, I would probably get this too." It stops the threat before an employee gets phished or something gets downloaded to their computer."
- "When it comes to the comprehensiveness of the threat protection from these products, so far I have seen how it's able to pick up the smallest script that is hidden in any type of malicious file."
- "If there were more template queries in the library, that would make it much easier. They could have basic things, like, "Where's the IP for this user?" or, "What file was downloaded from this user?" If there were more of those basic queries that would help."
What is our primary use case?
Our server is on Azure, so we get alerts on Microsoft Defender. If it's an endpoint alert, we investigate the endpoint based on the type of endpoint it is, whether it's a computer or a phone, et cetera. We then figure out what kind of file was downloaded, if it was bad or good, based on the hash file.
We also use Microsoft Defender for Office 365 for email, where we get alerts based on phishing emails, spam, and we investigate them. We also do Sentinel queries, with KQL (Kusto Query Language).
How has it helped my organization?
Automation has had a positive impact. When we have a lot of false-positive alerts, we are able to set up a condition in Microsoft Defender where it will automatically close that as false. I don't create those conditions, that's something our security engineer does, but it makes my job easier.
Also, threat intelligence helps against potential threats before they hit. You can actually block and delete the emails from MDE whenever you detect them, or when they report, "Hey, this is a phishing email or spam email." It's also able to block and detect a bad or phishing URL. It has decreased our time to respond because if it detects a URL, we're able to automatically block and delete it before a user even sees their mailbox the next morning. It's very fast in detecting and we like that.
As a SOC, it has saved us time, on the order of 60 percent of our time.
What is most valuable?
The Microsoft Sentinel part is the most valuable when you have to search for the malicious folder or file the user downloaded. We use it to ingest data from our entire ecosystem and that is very important if we have to go back 30 days and investigate cases, and we need more details. It's able to ingest that much data. That's pretty important.
Sentinel also enables us to respond holistically from one place and that's good for my job. It makes it easy.
Also, the visibility into threats that the solution provides is pretty awesome. I had never actually seen this type of technology before. It was the first time I had exposure to the cloud. This is something that makes me think, "Wow, okay. If I had my own organization, I would probably get this too." It stops the threat before an employee gets phished or something gets downloaded to their computer. Even if it gets downloaded to the computer, it doesn't spread to the other networks, because Defender will automatically block it.
Another thing that is pretty awesome is that our Microsoft security products work natively together and deliver coordinated detection and response throughout our environment. As a SOC person, it makes my job very easy.
When it comes to the comprehensiveness of the threat protection from these products, so far I have seen how it's able to pick up the smallest script that is hidden in any type of malicious file. It's so good. And it gives you all the details: what kind of script was run, what kind of hash file, and what type of command was run. I'm pretty happy with it.
What needs improvement?
If there were more template queries in the library, that would make it much easier. They could have basic things, like, "Where's the IP for this user?" or, "What file was downloaded from this user?" If there were more of those basic queries that would help. I haven't seen basic ones, but there are a lot of advanced queries, where people need to know the KQL language to understand them. I'm still learning so that's why I'm providing that feedback.
For how long have I used the solution?
I have been using Microsoft Defender for Endpoint for almost a year.
What do I think about the stability of the solution?
The stability has been really good so far. I haven't seen it go down or have an issue where it didn't work.
We have had some integration issues when something breaks, but that's just occasional. So far, it's good.
What do I think about the scalability of the solution?
We have it deployed across various departments. The IT users have more privileged settings.
Which solution did I use previously and why did I switch?
When I started with this company we used Splunk before we switched to Sentinel. We switched because Sentinel seems way faster.
How was the initial setup?
I wasn't involved in the setup of the solution, but when it comes to maintenance, we have security engineers who maintain our alerts, in case there are false positive alerts coming in.
What other advice do I have?
Work on Sentinel. It has a lot of power versus the Microsoft Defender solution.

Out-of-the-box and brings more value to customers; provides technically sound support, but is not as robust and not as customizable
Pros and Cons
- "What I found most valuable in Microsoft Defender for Endpoint is that it's out-of-the-box, which brings more value to the customer. The technical support for the product is also one of the best parts, because it's good, in terms of the product knowledge of the technical engineers."
- "Microsoft Defender for Endpoint is not as robust, and you cannot customize it much, so that's a challenge."
What is most valuable?
What I found most valuable in Microsoft Defender for Endpoint is that it's out-of-the-box, which brings more value to the customer. The technical support for the product is also one of the best parts, because it's good, in terms of the product knowledge of the technical engineers.
What needs improvement?
In Microsoft Defender for Endpoint, the devices still need to mature a little more when compared to other AV solutions. Microsoft Defender for Endpoint is not as robust, and you cannot customize it much, so that's a challenge. These are the rooms for improvement in the product.
Microsoft Defender for Endpoint is still being improved. I would say it's still in the development stage. Daily, Microsoft is getting feedback from the customers, so they are modifying the product based on the feedback and requirements of the customers. It's an ongoing process, and as a consultant, I'm in a much better shape, from a consultant point of view, in terms of speaking with customers.
What I'd like to see in the next release of Microsoft Defender for Endpoint is a single console where you can manage all the policies, Intune, and the EDR capability that can be managed through Intune. There should be a single portal for that to make it more convenient for the security consultant engineer to work with. Right now, I have to hop between different controls. Even the tenant attach feature needs to become more mature in Microsoft Defender for Endpoint because it's just very basic. The concept is good, but it's very basic, so it requires more effort for the engineer to configure.
For how long have I used the solution?
I've been dealing with Microsoft Defender for Endpoint since 2018.
What do I think about the stability of the solution?
Microsoft Defender for Endpoint is a stable product.
What do I think about the scalability of the solution?
Microsoft Defender for Endpoint is a cloud solution, so it's always scalable.
How are customer service and support?
Technical support for Microsoft Defender for Endpoint is good, and it's the best part. Microsoft knows that the product needs some development, so they're working on improvements, but all the technical engineers I've worked with so far are very technically sound and they know the product.
How was the initial setup?
The initial setup for Microsoft Defender for Endpoint is straightforward, if you are aware or have knowledge of it. For example, it's easy if you have gone through all the phases of setting up Microsoft Defender for Endpoint when it started as a manual deployment, manual configuration, then it came through GTO, then SSCM, then Intune, and now SMM. If you have gone through all the phases of deployment, then you know where you need to go and where to change the settings.
If you just started with Intune, or you're dealing with a combination of Intune and a firewall, the initial setup won't be as easy. It could be challenging for a newcomer, because you do not have much experience with Microsoft Defender for Endpoint, but they'll give you good support, and they'll try to resolve the challenges that come up when setting up the solution.
What's my experience with pricing, setup cost, and licensing?
Pricing for Microsoft Defender for Endpoint is competitive. Out of the bundle, you will get a lot of security, if I talk about Microsoft E5, for example, and get a lot of benefits. If the customer goes and purchases a different solution, it will cost more, so pricing for Microsoft Defender for Endpoint is quite reasonable at the moment. There isn't any challenge in terms of pricing, for example, I didn't see a customer who pulled back because of the price. Some prices could be negotiable, and sometimes, as a sales point, the two become negotiable, but they don't bill one and pull back because of the pricing. If you have an E5 license, you get everything.
Customers don't worry about the prices too much, because what they're a little bit worried about is the complete capability of Microsoft Defender for Endpoint in the endpoint security space when compared to other legacy solutions such as McAfee Endpoint Security and Symantec End-User Endpoint Security that are quite mature enough in this market, as seen on Gartner. Sometimes the customer is reluctant to move to Microsoft Defender for Endpoint, but not because of its price. I didn't have customers who questioned the pricing for the solution.
Which other solutions did I evaluate?
I'm currently working with all these solutions: McAfee Endpoint Security, Symantec End-User Endpoint Security, and Microsoft Defender for Endpoint, because I'm a consultant. I'm not a customer. I do use it, and the organization I'm in uses it, but I'm a consultant to the customer. I do pre-sales and look into any of the technical aspects of Microsoft Defender for Endpoint.
In terms of comparing Symantec End-User Endpoint Security with Microsoft Defender for Endpoint, they both work, but in different ways and they have different approaches. Microsoft Defender for Endpoint doesn't have HIPS, while Symantec End-User Endpoint Security has HIPS. Microsoft Defender for Endpoint has ASR rules which are compulsory, but there are some activities that Microsoft Defender for Endpoint can't do in an environment, particularly if it is an air-gapped network. In an air-gapped network, which is very secure, my team can't open the internet, and Microsoft Defender for Endpoint fails in that, despite being an EDR solution, because it's cloud-based and it doesn't work there. Microsoft still doesn't have any solution for mitigating the air-gapped network.
What other advice do I have?
My advice to people looking into implementing Microsoft Defender for Endpoint is to do it very fast because the tool is changing very rapidly, so if you are a novice and you are just learning, what you learn might get changed in the next quarter. Some of the functionality might get changed, so you need to keep up with the changes, and you need to learn quickly and implement Microsoft Defender for Endpoint fast.
My rating for Microsoft Defender for Endpoint is seven out of ten.
