The solution is stable.

It's pretty stable.

With a browser or web-based system, it might confuse things, saying, "You don't have access," because you should have logged in with your admin credentials but you logged in with your standard user credentials because you are on the same desktop.

Defender is robust.

The solution is stable.

The product is stable. 

Its stability is lesser than some of the competition. I've seen machines having a blue screen. I've seen machines block, but it is usually a problem related to the lack of resources. I wouldn't deploy it on a machine with less than 16 gigs of memory. All the issues that we had on the laptops were essentially related to memory because it does all the analysis in memory, and it eats a lot of memory to do that. So, stability is more a function of making sure that your endpoint farm has what's available. If you've got less than 16 gigs, I would not recommend it. You need to either change your endpoints or consider using another solution because although it'll work, it can be very slow.

The product is fairly stable. 

It's pretty stable. I haven't had any reliability concerns with Defender, and there have not been too many complaints from users that have to have extensive reboots or any kind of performance impact. So I would say it's pretty stable.

Microsoft Defender for Endpoint is stable.

Its stability is very good.

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.

With Windows, we have been very happy. We have had no issues or problems whatsoever. We had one issue on the Mac OS platform when an update to Mac OS was deployed. It wasn't a major update, like Monterey. It was a point update. So I think it might have been 12.2.1 where the Defender icon was starting to display across, which means I found a threat or it's not working properly. We had that across a handful of machines. I did a bunch of Google searches and sort of realized this was happening to a lot of other organizations, so it was probably a false positive.

I contacted Microsoft support who confirmed that it was just a visual glitch. I guess Apple is well-known for this. When they do push out their updates, they attempt to break the occasional third-party system. That was the only issue that we have encountered, which was more a visual glitch than an actual threat.

It is pretty much zero-touch because the definitions sort of update themselves. The application updates itself because it is deployed through Microsoft Intune. Therefore, the maintenance is pretty straightforward.

Microsoft Defender for Endpoint is stable.

We have never seen any downtime in it, so it is incredibly stable.

We have never had any downtime or any other issues.

It's not very stable because Microsoft keeps making a lot of improvements as it's a new product. For example, today I might see something on one page, on another day, it might be located on some other page or portal. However, I have seen stability to some extent over the last couple of months.

The solution is stable. There are no bugs or glitches and it doesn't crash or freeze. It's reliable and the performance is good.

Defender's stability is one of the things I love most about the solution. 

The stability of Microsoft Defender for Endpoint is good.

Its stability is fine. It is a built-in and legacy solution. It can stand up to any other endpoint security solution. 

It's very reliable and very dependable. I don't see any issues with it. In fact, it's the best product I have used because it's integrated with Windows 10. It doesn't eat up resources while running like other products. It's a really well-thought product.

Microsoft Defender for Endpoint is stable.

The stability is great.

I can't think of any ongoing issues that we have other than our own internal minor configuration. I don't know if this is in there, but I would love the ability to see how we're deployed and get recommendations.

Microsoft Defender for Endpoint is extremely stable.

The solution is solid. 

The biggest "catch" is that clients do not always want to implement systems according to the manufacturer's best practices. There's always friction if the client has in mind one way it should be, but it was designed differently.

In our case, we're talking about a big company that is used to being a big enough client that the vendor will change what they do to accommodate them. Microsoft does not have to. That's not a criticism of Microsoft. It's just that Microsoft is big. They are not a little regional provider. They will not change something in their product that's distributed globally to accommodate a client with a non-standard way of wanting to implement something. There's friction with that. 

I do not see that as friction with Microsoft because of Microsoft, I see it as the friction of a client that takes a solution from a huge provider but sometimes has the mindset that they want the attention that comes when they purchase a solution from a small provider.

Microsoft Defender for Endpoint has been stable in our usage.

It's a stable solution.

It's stable. From time to time, there's a blackout on the web pages.

So far, so good. We haven't had any issues related to the service not being available or anything like that.

Microsoft Defender for Endpoint is extremely stable.

Microsoft Defender for Endpoint is a highly stable solution.

When testing to see if the antivirus solution is working properly with a lot of different events occurring on the device, we found that the Defender interface can become cluttered. The solution does not always give us a real-time view of what is happening, making it difficult to navigate the user interface. Therefore, there is potential for improvement in terms of stability.

The solution is very stable, and that has improved with time. It used to be hard on the workstations, but we experienced those issues eight years ago. Microsoft always came out with a patch within a week or two, which would fix the problem. Nowadays, the tool is very stable; the only potential issue is if something happens on the cloud end, as the dashboards are cloud-based. That's something I've yet to personally experience, though.

I haven't seen any downtime. I don't see any issues with the stability. If there is any downtime, Microsoft will send a message on the dashboard and we can see any service issues.

I give the stability a nine out of ten.

It's very stable.

Generally speaking, there are no bugs or glitches. We have had issues twice in the past two months, but nothing too critical. Before those two occasions, it hadn't happened in a year or more.

Microsoft Defender for Endpoint is a stable product.

The stability is good.

It is a stable solution.

It is good. It is stable. Once you set it up, it works, but we haven't tested it on a large time scale. The solution itself is pretty young. We'll see how stable it will be in the next few years.

The product is very stable and quite reliable. There are no bugs or glitches. It doesn't crash or freeze. The performance has been good. 

Microsoft Defender for Endpoint is stable.

It is stable.

It's quite stable.

Its stability is quite good, especially with Windows 11, which is a very stable operating system. Of course, you can run into some issues. We have some issues with docking stations for Surface and screens, but generally, the operating system together with the endpoint security solution is very stable.

The stability of Defender for Endpoint is very good. I haven't had trouble with it.

It has been quite stable up until now. It does not break. Microsoft is developing on it quite frequently and more and more features are coming in, but overall it is quite stable. It does not break that often.

As we have moved away from Microsoft Defender Antivirus and to the EDR solution, we have seen very few issues so far that users have faced with this. There have been very occasional performance issues for some users, but they have been very rare.

This product is pretty stable.

Microsoft Defender for Endpoint is generally stable, but the frequent product changes made by the development team have caused several instances of unusability this year. These changes often introduce bugs that disrupt web functionality, bringing it to a standstill. While the product itself is stable when not affected by these bugs, the recurring issue has occurred three or four times in the past year.

It is stable.

The solution is stable; Microsoft goes down very rarely. It happened just a few times over my career. If it does go down, the impact is significant.

The stability is excellent and I've never encountered any issues; it has consistently performed well.

Microsoft Defender for Endpoint is stable. I have only experienced one crash.

Because it is in the cloud, the stability is good.

The solution is stable. 

The stability has been fine. There are no bugs or glitches and it doesn't crash or freeze. 

The stability of the product is good. I have not dealt with bugs or glitches. It doesn't crash or freeze. the performance is good. It's reliable. 

Stability-wise, I have not had another product that has been as stable and has had fewer issues. It's amazing.

We haven't had any issues. I haven't had any bad experiences. I expect it to work, and it works. It is just there. For example, when you have Word or the whole Office package, as long as it works, people are happy. You just have it, and you don't have to say, "Oh, this version is really..." It is just Microsoft. For most users, Microsoft is Windows, Defender, and the Office package. As long as you just use that, then people will say, "Okay, we're just basically using Windows." They don't care about one thing or another, as long as IT works.

As long as things are slowly upgraded, it works, and we don't have any issues, then I am happy.

In terms of resources, I believe the solution is more resource-intensive because I can initiate multiple automated investigations, which will likely take a day or two to complete.

I rate Defender a nine out of ten for stability. 

The stability is okay.

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.

In comparison to the other solutions that I've had experience with, Microsoft Defender was very good.

Stability-wise, it is responsive and I don't see any drawbacks. They have additional features that make it a little more robust.

The solution is stable.

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.

It is stable.

The solution is stable and responsive. 

The solution is very stable. There are no bugs or glitches. It doesn't crash or freeze.

Like every other security product out there, the stability of Defender for Endpoint is a work in progress. The solution is trying to address a tough problem and anybody will tell you that cyber security is not a fair fight. It's just incredibly hard to defend against the bad actors. Everybody is scurrying right now to come up with different ways to stop the problem and it's just not there yet.

We are testing it right now and we didn't get into the production state just yet. Therefore, it's hard to gauge the capabilities in terms of stability. So far, however, it has been stable.

Microsoft Defender for Endpoint is stable, except for occasional internet connection issues, but it's stable.

Microsoft Defender for Endpoint is stable in my usage.

It is stable for the time being. 

It can get a little laggy sometimes, but overall, it's fine when investigating events.

We need to test its functionality in heavy environments.

It is still a new product, and there are many reported bugs in terms of stability and impact on the endpoints.

This is a very stable solution and we plan to continue using it.

It is very stable. It is highly recommended.

It's very stable.

Microsoft Defender for Endpoint has been stable.

It's a stable solution.

I would rate it an eight out of ten in terms of stability.

Microsoft has some creative accounting when they promise an SLA of 99.99%. But it is generally good. There's always going to be a problem with the cloud. If it works 99% of the time, that's great.

The frustrating thing is, you're not sure if there's a problem with your configuration or if the service itself is down because Microsoft tends to only report that the service is down much later than when you started experiencing things. So sometimes I have to jump onto a private forum or a Slack channel and ask other consultants if they experienced something similar. But when it works, it works. There's never going to be a cloud solution that has 100% uptime.

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.

This solution looks stable. Provided that Windows 10 is updated, everything is okay.

Defender is stable, I haven't had any problems with viruses when using it, and it's easy to update.

Microsoft Defender for Endpoint has been stable. It does not slow down my computer.

We had absolutely no issues with the stability of Microsoft Defender for Endpoint. We did not experience any bugs or glitches.

This is a stable product. We have been using the standard version for a long time and it hasn't negatively affected our environment. Generally speaking, it is reliable.

I give the stability an eight out of ten.

It's quite stable. Sometimes it can overload the CPU of endpoints, but Microsoft provides ways to solve this problem.

The stability is good. It's a stable platform. I don't see any issues right now. However, I did see something in the past. I can't quite remember the exact situation. It's resolved and right now there are no issues. 

Stability-wise, it is good, and it performs very nicely.

This is a stable solution that has matured over the years.

It seems stable.

With what we have seen, it's a stable solution.

The stability is great. It just keeps getting more and more stable. As it matures, it's going to be very good.

I don't recall any issues with the solution.

The solution was very stable.

It performs well. The stability is seamless.

I find the solution to be stable. 

The solution is stable and secure.

It's my understanding that the solution is very stable. It's a pretty mature solution.

It's really stable. I've used a lot of products, like ESET and Kaspersky. None of them are comparable with this one. This one is much better.

Microsoft Defender for Endpoint is a stable 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. 

It is very stable.

You do not need to worry about maintenance. It is automatically updated. Sometimes it will show you a red marker to do a system scan. People normally kind of ignore that, but I suggest people do a system scan from time to time. Now, what happens is just a bubble icon showing a red cross sign, but that may not be enough. It should give a pop-up window to remind people to scan the system once a month or quarter. It should be built-in scanning, without asking anybody, once per month or quarter.

The solution is stable.

It is stable, but it depends on how you configure the existing ATP and what existing features you need to enable it.

Based on the features that are enabled, it will work perfectly. 60% to 80% will depend on the configuration that is done for the ATP trade products.

It's a stable product. Microsoft only recently entered this market and nobody believed that Microsoft antivirus would be good. They are now trying to prove everyone wrong in that sense by having a good security product. 

The solution is very stable. It has good features that make it efficient in the security aspects of our systems.

It's a good product but it is limited in some cases. I had a bad experience because a few weeks ago I was in Seoul in Korea and with my Dropbox, my children did some things on my computer at home and I got ransomware to Defender and it corrupted my whole Dropbox. The stability can use improvement. 

This solution is very much stable.

It is stable.

In general, Defender Antivirus can work with my operating system. So, its performance is okay.

The solution is quite stable. It goes well with Windows applications. We haven't had any issues with it so far. It doesn't crash or freeze or glitch. However, we haven't tried the app just yet. 

Windows Defender is a stable product and we plan to continue using it in the future.

In my experience, Microsoft Windows Defender has never caused any issues as such. It is pretty much stable and has not affected the system resources as per my observation.

Microsoft Windows Defender is stable.

This solution has very good stability.

Microsoft Defender for Endpoint is stable.

I like its stability a lot.

We have onboarded a number of machines without any issues.

We find that Microsoft Defender Antivirus is very stable. We've experienced complications with other solutions in the past and found that this is one of the most stable solutions. It's also very scalable, too.

It is very stable for Windows.

The stability of Microsoft Defender for Endpoint is good.

It's stable. There are no issues that I know of. 

My laptop has been working.

On Mac, it's quite unstable and unusable; however, it's very stable for Windows. We're content with what it does and how it works.

Defender is stable enough and is competitive with the other products in the market.

Stability-wise, this is a strong product and it works better than other anti-virus solutions.

The solution has been stable.

Microsoft Defender for Endpoint is stable.

This solution is quite stable. In our opinion, it's similar to those signature-based antivirus software, and almost at the same level. 

The solution is stable.

I haven't had any noticeable issues with it. It's quite stable.

The solution is stable and working fine for me. I haven't faced any problem with it.

The solution is stable but sometimes when you do a security update when it starts, you see the hinge process in Task Manager. It also sometimes corrupts the PC. You need to either start it or recalibrate. If the installation happened without it starting, like patching without starting, it's better.

With Windows Defender, it will want to do these updates so that when you install an update it has to be done with a Windows update and then you can start. If you can manage it easily in a natural phase like updating security, ejecting and installing, it's better. Like checking a box.

I've been using this solution for three years and haven't had any problems. 

The solution is very stable. So far I haven't had any issues on my laptop. It uses very little resources. It doesn't crash or freeze. There aren't bugs or glitches that I have noticed.  It's reliable.

So far, we haven't had any issues, and we're using it for the server right now.

For the most part, free things are not as effective as licensing or something you purchase. That's why many times our clients ask for a licensed antivirus such as Kaspersky. Our clients do ask for licensed Kaspersky or BitDefender, or other antiviruses. Windows Defender, which is just a free version, is not as effective. It doesn't have deep support or deep protection.

It is stable.

Windows Defender is very stable. We have not experienced bugs or glitches at a rate higher or lower than other software.
