851,823 professionals have used our research since 2012.
What do I think about the stability of the solution?
Microsoft Windows Defender is stable.
What do I think about the scalability of the solution?
We have had no issues with scalability.
How are customer service and support?
We have not needed any support from Microsoft so far so there are not any complications with customer support so far.

Information Security Analyst at a financial services firm with 501-1,000 employees
A security implementation that supplies proactive issue resolution with cloud analytics and APT
Pros and Cons
- "This is a very go, proactive solution to threat protection using advanced analysis."
- "Updates are not coming out of preview quickly enough and it is holding back on the development of the product."
What is our primary use case?
Our primary use for the solution is threat detection and response.
How has it helped my organization?
It's basically for security implementation, response planning capabilities and other security functions. Obviously, auditing, HR, requirements, legals, auditing, banking, and financial services all require a lot of the data that are generated and reported out of the platform.
What is most valuable?
The features that are most valuable for us are cloud analytics from the APT (Advanced Threat Protection) engine or quarantine, deletion, and removal. Basically, they work by web engine. Simply, it is proactive in resolving potential issues.
What needs improvement?
There are certain features that do have room for improvement. I think with the analytics engine they're looking at it from the desktop and the server perspective. I think the desktop engine should also include the script analytics — what executed, what's the power shelf or UI commands, or some form of Splunk regex. I know we don't have that functionality with a run-time analytics platform, but it's a JS (JavaScript) based one. So it would be good if they had a regex to JS converter.
The biggest problem is they need to take things out of preview. I know that they're developing on the platform service with the analytics engine, but so many services still rate it as a preview after 12 to 18 months, which is stopping adoption with businesses knowing that that solution could be filled and redirected at any time. So that delay is limiting technology to be able to be updated because they don't have to release all production support.
For how long have I used the solution?
I've been using it for about eight-and-a-half years, if you add the early adoption projects.
What do I think about the scalability of the solution?
In the last 12 months, we've moved up to the Gartner Magic Quadrant report as a leading form of threat analysis. Obviously, the more clients that migrate to Cloud Services the more analytics platforms are picking it up. There are auto-resolutions and it's getting more cross-correlations between tendency. So we're getting a lot more APT (Applied Predictive Technologies) and IOC (Indicators of Compromise) data through which you can get a better response, better response times, automatic remediation tasks, reduce the amount of the alerts and false positives — that sort of thing. It's all really useful. It's scaling out on its own.
How are customer service and technical support?
We get direct support. They're literally across the road from us. We've got multiple Microsoft engineers assigned to our contract as well, so we deal directly with their engineering teams.
How was the initial setup?
The setup was simple and straightforward.
Here we SCOM (System Center Operations Manager) SCCM (System Center Configuration Manager) deployment for pushing out the agent's, done the deployment for the AIP (Azure Information Protection) scanners and load that unified data locally.
What about the implementation team?
We consulted with Microsoft, but we're a full IT workhouse so we have qualified engineers that were coming off a three-year capability program to deliver all of those services.
As far as the amount of staff we use to support the solution, we have a lot of managed providers and different international SOC (Security Operations Center) teams and different agencies that manage a lot of the services. I would say that globally we would have probably about close to a hundred engineers working on the solutions full-time with cloud app development and Kubernetis and things like that.
Which other solutions did I evaluate?
We compared extensively between multiple services, everything from Azure, cloud service providers, identity providers, platform SaaS providers — we did all that before we sort of consolidated on certain technologies in different areas.
We're utilizing a lot of the services. There will be some future state planning goals, but we're taking a risk-averse assessment on the product. We're more controlled about how things like our customer member data protections, cryptography and those types of things are working. So we're doing still doing a little bit of assessment. I know it's got the ASD clearance rating and certain services, but that's based off the tenancy agreements.
What other advice do I have?
I'd say the product rates about an eight out of ten as it currently stands.
You have to implement the product — there's no choice. You can't use the exchange online protection or the advanced analytics or obscure identity IP protection without the APT being installed on the endpoint. Otherwise you're not getting into threat intelligence or the actions. You're not going to get the full response plan or activities that occurred. You cannot deploy without APT being installed on the desktops and have a full, defined solution for unified labeling. That has to be deployed and tested for unstructured data for at least six months with the AIP (Azure Information Protection) scan that's deployed with APT.

COO at Floating-Dot Technology LTD
Free software to prevent malware and viruses that is bundled with the operating system
Pros and Cons
- "It's free. There is no additional cost. It's part of Windows."
- "Microsoft Windows Defender doesn't have a game mode."
What is our primary use case?
Our primary use case for Windows Defender is to prevent malware and viruses. Security is the main purpose that it is used for by our organization.
How has it helped my organization?
We are no longer buying a separate antivirus with Windows 10 Server Enterprise. We are no longer buying antivirus solutions where there is no compatibility with Windows 10.
What is most valuable?
The malware features are most valuable for us because if you have an application that attacks, it is defended. It gives you a prompt and doesn't allow you to launch that app.
If there's an application that has suspicious malware you downloaded from the internet, it gives you a prompt to prevent the application from launching.
Microsoft Windows Defender moves it to the recycle bin automatically.
What needs improvement?
Microsoft Windows Defender doesn't have a game mode. Other antivirus software (like BitDefender) have something known as a game mode.
If you want to play a game, just enable the game mode to allow certain traffic without needing to configure it. Windows Defender doesn't have that.
There's no Windows Server edition for Windows Defender as part of the distribution.
For how long have I used the solution?
Personally it has been about a year and a half, but in the office are we using it seven months.
What do I think about the stability of the solution?
In my experience, Microsoft Windows Defender has never caused any issues in operation. It is very stable. It doesn't affect the system.
What do I think about the scalability of the solution?
Since it's a Microsoft product, scalability is top-notch. This shouldn't be an issue.
How are customer service and technical support?
I have never had a problem with technical support. I didn't use it. I have never had any performance issues with it.
Which solution did I use previously and why did I switch?
We used Bitdefender, McAfee, and Norton antivirus software previously. Those are the main experiences that we have. We used all of those at various times.
How was the initial setup?
Microsoft Windows Defender installs automatically. There's no setup procedure. When you install Windows Suite or Enterprise on your machine, it installs quickly.
There's nothing that might disturb it being activated. It installs with the operating system.
What's my experience with pricing, setup cost, and licensing?
It's free because it comes with Windows. It's a free solution. We're not paying any license.
That's why it's better than Bitdefender, McAfee, or Norton. It's free.
What other advice do I have?
For Windows Defender, there's no server edition for it. It's free. There is no additional cost. It's part of Windows, i.e. if you have issues with compatibility using other products.
If you paid for Windows, it already comes with Windows Pro and Windows Enterprise automatically. It's better to go with it than pay the additional expense of deploying other solutions.
On a scale from 1 to 10, I would rate this product a nine. It doesn't have all the features that it needs to be perfect.

System Engineer at Dr. Marc Daenen
A standard malware and antivirus solution — nothing more, nothing less
Pros and Cons
- "Microsoft Defender for Endpoint is quite good. We haven't really experienced any issues with it."
- "I personally haven't experienced any pain points, but some of my coworkers feel that it isn't secure enough."
What is our primary use case?
Just as the name states, we use this solution to defend endpoints.
We're actually in the process of moving away from this solution. We are beginning to use SentinelOne.
What is most valuable?
For me, It's just a standard malware and antivirus solution — nothing more, nothing less.
What needs improvement?
I personally haven't experienced any pain points, but some of my coworkers feel that it isn't secure enough.
It would be nice if they could guarantee that we'll always be safe and secure with them.
For how long have I used the solution?
I have been using Microsoft Defender for Endpoint for roughly four years.
What do I think about the stability of the solution?
For me, this solution is both reliable and stable.
How are customer service and technical support?
I have never had to contact their technical support.
How was the initial setup?
The initial setup was straightforward.

Consulting Director at a tech services company with 5,001-10,000 employees
Reliable protection included with Windows Operating System
Pros and Cons
- "It's stable."
- "I would like to see fewer pop messages and alerts."
What is our primary use case?
I'm a consultant and I don't use these solutions. We sell them and we do research for sales purposes.
I don't use it explicitly. Rather, it's there on my laptop filtering viruses. It's there to protect my laptop.
What needs improvement?
I have had a few minor issues on my laptop but nothing really big.
I would like to see fewer pop messages and alerts.
It's disturbing when you have that many alerts.
Even though it shows you it's working, I don't really need to see it. If it was running in the background and never showing that would be perfect for me.
For how long have I used the solution?
It's been a part of my laptop by default for two to three years.
I am probably not using the latest version. I don't follow the best practices in terms of updates. I may have an outdated product.
What do I think about the stability of the solution?
It's stable. There are no issues that I know of.
My laptop has been working.
What do I think about the scalability of the solution?
As it is for my personal use, this is an area that is not necessary for me to explore.
I am the only person using it.
I am a part of a tiny organization with a tiny team that is autonomous.
How are customer service and technical support?
I have not contacted technical support.
Which solution did I use previously and why did I switch?
I have used Symantec Endpoint Protection. It was the standard choice in my previous company.
How was the initial setup?
From what I remember, the initial setup was transparent. I haven't had to deal with it.
I would say that the initial setup was straightforward.
What's my experience with pricing, setup cost, and licensing?
It's included with the Windows Operating System, I don't pay for any licensing fees.
What other advice do I have?
I would recommend using this solution. I haven't had any issues and it's been working fine for me.
I plan to continue using this product as long as it is not causing any problems.
I would rate this solution an eight out of ten.
