Automatically isolates threats and integrates with logging to reduce response time
Overall, I would evaluate the Microsoft support level that I receive at probably about a seven, but that depends on the day. It has been spotty. We have had issues where the urgency level of the Microsoft support is not as high as ours, especially during a data breach or potential data breach situation. We have had issues with some of the offshore support being lackluster. One specific thing that comes to mind is we were on a support call with our CISO on the call, and the Microsoft agent, who did not actually work for Microsoft, is one of the vendors that Microsoft uses for support, said, "Just to set expectations, my lunch break is in an hour and I am going to go away then." For us, it was already ten o'clock at night and we had been working on this for a couple of hours, trying to get a security engineer on with us. For him to tell us that he was going to go away and have lunch, it was, "Okay, but go find somebody else if you need to." It was just the lackluster approach, and it seemed like he did not really care. We seem to get a lot of this when we get non-Microsoft support. I can identify areas for improvement with Microsoft Defender for Endpoint, as it is kind of a convoluted mess to try to take care of false positives. Especially when they have been identified as false positives but they keep going off over and over again. It is great for my pocketbook because it generates a lot of on-call action, but I would really prefer more sleep at two o'clock in the morning than dealing with false positives. I would say that the unified portal for managing Microsoft Defender for Endpoint is suitable for both teams as they are all in there. It would be great if they would stop moving things around and renaming things, which makes sense. The new XDR portal is pretty nice. Being able to have it central again inside of the regular Security Center without having to open up two windows is helpful. Overall, I think it is pretty good. There is always going to be something that could be improved, such as alerting and the ability to modify alerts would be a little bit helpful to have. Being able to add more data into the alerts and turn off alerts that are not as useful would be beneficial. It is hard to say what the quantitative impact the security exposure management feature has had on our company's security, because a lot of it is kind of subjective. I think we are sitting at around a fifty percent score still, and a lot of it is just kind of unusual circumstances that we cannot really implement without breaking the organization.

Lockdown devices and ports on endpoints so that you can stop propagation of any virus if it's detected but performance utilization can be better
It's scalable in the form of it now covers mobile devices as well as a number of other different types of devices, not just Windows. Also, there's no limit as to how many devices you can install it on. We plan to expand the number of devices/users as we get more people onboard or upgrade to more mobile devices; we will then increase the number of licenses for mobile devices. We've got 450 licenses, but we've got about 375 devices and users currently. I would rate the scalability a ten out of ten. There's not a product yet that I've found that I can't put it on, especially now that they've got the new release, which was the mobile agents.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The primary advantage is that you don't need to install it, because it's included in the Windows 10 delivery and is integrated as part of the Microsoft 365 suite."
"There are several features that have helped to improve our security posture at the prevention level, such as the attack surface reduction controls and the exploit prevention control."
"It's got good detection rates, low on system resources, doesn't interfere or hamper workflows, and it's easy to use."
"The performance of Microsoft Defender for Endpoint has been a valuable feature."
"Because it has been integrated with the OS, we get the entire software inventories, and we even get access to the registries. Those are the primary features."
"Microsoft Defender for Endpoint is beneficial because we are using Microsoft Windows and all the core solutions are made by Microsoft, such as the authentic platform, operating system, and antivirus protection. It is a heterogeneous environment. We had to use third-party solutions before and update everything separately. For example, the policy for antivirus. With Microsoft Defender for Endpoint, when Microsoft Windows receives updates it will update with it. This is one main advantage of this solution."
"The attack surface reduction capabilities stand out as the feature I appreciate most, particularly the manner in which they can be customized to organizational functions, such as having separate policy elements and provisions for finance versus IT versus standard end users."
"Microsoft Defender for Endpoint is a robust platform."
"The automated response capability in SentinelOne enhances security operations. It means I don't have to worry about having too many security people watching it because you can automate a lot of the tasks."
 

Cons

"I have accounts for administrators and corporate employees, but I also have accounts for students. I can't split these types of accounts. I need a separate configuration for both... I need to research how I can get alerts for only the administrative machines."
"We encountered some misbehavior between Microsoft Office Suite and Defender. We had issues of old macros being blocked and some stuff going around the usage of Win32 APIs. There is some improvement between the Office products and Defender, and there is a bunch of stuff that you can configure in your antivirus solutions, but you have several baselines, such as security baselines for Edge, security baselines for Defender, and security baselines for MDM. You have configuration profiles as well. So, there a lot of parts where we can configure our antivirus solution, and we're getting conflicting configurations. This is the major part with which we're struggling in this solution. We are having calls and calls with Microsoft for getting rid of all configuration conflicts that we have. That's really the part that needs to be improved."
"Microsoft Defender for Endpoint can use more advertising to promote their features."
"The initial support process can be lacking as first-line support is sometimes not well-versed technically, resulting in repeated exchanges to finally engage a knowledgeable support person."
"Windows Defender, which is just a free version, is not as effective. It doesn't have deep support or deep protection."
"One thing that was lacking in Defender was web filtering. Its web filtering wasn't as comprehensive. Sophos was a little bit better than Defender for blocking URLs or installing programs."
"Microsoft Defender for Endpoint can have more options and more AI capabilities in the future, because everything keeps changing."
"The solution could be more friendly for end-users, with different type of scans or scheduled scans for it."
"The performance utilization on the device that it's monitoring. This aspect needs improvement."
 

Pricing and Cost Advice

"We have an enterprise agreement so from my perspective, this is a product that ships with Windows and it is not priced standalone."
"When customers haven't deployed the solution and don't have licenses, it can be expensive to start from scratch."
"The solution is an open source version and was free with a paid version of Windows 10."
"Because Microsoft Defender comes as an add-on, it can be a bit expensive if you're trying to buying it separately. Another option is to upgrade, but the enterprise licenses for Microsoft can also be quite a bit pricey. Overall, the cost of Microsoft Defender compared to that of other endpoint detection solutions is slightly higher."
"The solution comes as a part of Windows 10 and it is covered under its license."
"It is within the same range as other products. It is not too expensive, and it is also not cheap. Its price can be better, but, well, it is Microsoft."
"Microsoft Defender for Endpoint is an expensive solution."
"This product is included in the pricing for Windows."
"I would rate the pricing a three out of ten; one is very expensive, and ten is an absolutely cheap product."
