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?
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.

Team Lead, Process Improvement & RPA at Fidelity Bank Plc
Automation of routine tasks makes our processes more efficient
Pros and Cons
- "It automatically detects intrusion and malware."
- "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

Service Success Manager at a computer software company with 5,001-10,000 employees
Integration with Security Center and the Microsoft compliance score helps us improve security maturity
Pros and Cons
- "The integration of Defender, Security Center, and the Microsoft compliance score, is the feature we use most to share the results with our clients and to create a roadmap together."
- "I would like to see integrations with other products, such as Spunk and other CM solutions. That would create possibilities for me, and for a SOC, to consolidate all events in an older console, not one provided by Microsoft but provided by a third party, and use it to create more insights."
What is our primary use case?
Our use case is for financial groups and we use it to control malware, as well as for antivirus. Our focus is on using it as an endpoint solution, but we cover the older servers too.
How has it helped my organization?
Of course, we integrate Defender with Microsoft Defender Security Center and the Microsoft compliance score. We use these tools to check the maturity and to guide our clients in using the solution better. The result is that we see growth in security maturity.
When we need to create a new server, we follow certain steps. One step is activating the extension from within the server and using that to check and monitor, in a centralized console, the health of the server. Defender also provides additional information about vulnerabilities and opportunities to increase the overall security.
For example, it will tell us if a library being used has any vulnerabilities. This information is very important for us and for our clients. They use this information to go back to their developers and request fixes. Or it may identify a problem with something in a client's application, where they need another version to mitigate it. And again, when they apply the new version, we can check it using Defender to see if the vulnerability has been resolved.
What is most valuable?
The anti-malware feature is mandatory for us.
Also, we use policies to mitigate vulnerabilities, but the final compliance score from Microsoft shows us what level the client is at and what level is needed to achieve better results and increase security policy maturity. The integration of Defender, Security Center, and the Microsoft compliance score, is the feature we use most to share the results with our clients and to create a roadmap together.
What needs improvement?
I would like to see integrations with other products, such as Spunk and other CM solutions. That would create possibilities for me, and for a SOC, to consolidate all events in an older console, not one provided by Microsoft but provided by a third party, and use it to create more insights. Examples of such insights might be the need to create a new policy or the need to mitigate an attack happening now. This type of ability would create a new business case, one that doesn't only use Microsoft solutions.
For how long have I used the solution?
I've been using Microsoft Defender for Endpoint for two years.
What do I think about the scalability of the solution?
The scalability is amazing. Using Azure, the sky is the limit. You just need to understand the business case.
In some cases our clients have small environments, but in other cases they have big environments. Large clients may have 1,000 agents running. But as a consulting company, we work with many types of businesses and many environments of different sizes.
As I mentioned, if the client requests an integration with some third-party tool, we may need to use another tool or develop something to make this possible. But in most cases, you don't need to do so. You just activate it and check if your policy will apply or has already been applied to the server.
How are customer service and support?
We have no problems with Microsoft's technical support. My team resolves level-one and level-two problems, but when we need to check something directly with Microsoft, when it's a level-three issue, we open a ticket and talk with the engineers.
How would you rate customer service and support?
Positive
How was the initial setup?
It's so easy. All activity is in the cloud, for deploying the agents and policies. It's not complex.
You just click, one-two-three, and it's working. In some cases, the deployment takes minutes. If the client needs a particular window or has a critical application running on their machine, it takes more time because of that machine's situation. But in general, it just takes a few minutes.
The harder part, following this, is you need time, like with other tools, to check the events. The tool will provide some insights, but you need to understand them, and after that, share them with the client or with those responsible for taking action.
Which other solutions did I evaluate?
In addition to Azure, we have partnerships with AWS and Google. We focus on security and use Kaspersky as well. It's all according to the business case. We take the time to understand the business case and then build a draft solution, check it with the client, and after that, we choose the best tool, given the budget available from the client. We create one, two, or three options and the client selects what is best for them.
The main difference between Defender and Kaspersky is the scalability and the installation and deployment process which, with Defender, is so easy.
What other advice do I have?
My advice regarding Defender is the same for any other security solution: Check what you need, what types of logs and whether you will consolidate these logs in another tool. What type of knowledge will you bring from those tools to create and apply new policies and anticipate security problems?
Always check your needs with the business case. Aligning them will help determine what you need to buy. Check inside Defender to see what you need to activate. Every new feature you activate inside the cloud is billed and you need to understand if you really need each feature.
Defender has some effect on the endpoint itself but it does not change the user's work processes. It is a single tool on the endpoint to monitor the activities that happen there, but it does not affect the end-user.
But you need to understand the limitations. There are some limitations with Defender when it comes to non-Microsoft solutions. But that's not unique to Defender. It's the same with every tool. You need to understand its limitations.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Microsoft Azure

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.

Security Technical Specialist at a retailer with 10,001+ employees
Very user-friendly, offering safety, security and providing a phenomenal amount of good information
Pros and Cons
- "User-friendly, offering safety and security."
What is our primary use case?
It's an antivirus product, so its main use is to protect us.
What is most valuable?
This is a really good product, it's user-friendly and offers us safety and security.
What needs improvement?
The technical support could be improved.
For how long have I used the solution?
I've been using this solution for three years.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
In terms of scalability, we went from 10 pilot machines to 35,000 devices.
How are customer service and support?
The technical support isn't too bad but their responsiveness needs to be improved. I'd say it's their biggest issue.
How was the initial setup?
The initial setup is very easy, probably one of the easiest onboarding processes I've done. Implementation was done in-house and takes a few minutes per device; click it and go. I deal with anything related to antivirus patching and encryption and we have four cyber analysts that look after whatever comes out of ATP or Defender for Endpoint.
What other advice do I have?
My advice would be to plan carefully and make sure you take notice of what's coming out because it pushes out a lot of very useful information. It's a matter of having sufficient staff because the amount of information it gives you is phenomenal. If a company doesn't have sufficient resources then any other antivirus might work, but this thing produces so much useful information that if you're implementing this solution it's worthwhile having the staff to deal with it.
I rate this product 10 out of 10.
Which deployment model are you using for this solution?
On-premises
