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

"I've started to test it from the security point of view. There are plenty of features that are interesting, but at this time, the XDR functionality is most valuable. It is endpoint security on steroids."
"Defender is an ideal solution for web security."
"Real-time detection and cloud-based delivery of detections are highly efficient."
"The solution has an easy-to-use interface, is always updated, and is user-friendly."
"It's free because it comes with Windows."
"Defender is stable. The performance is good."
"It performs well. The stability is seamless."
"Auto-remediation: When the product sees malware, it resolves the issue immediately."
"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

"Microsoft Defender for Endpoint is effective for validating work, but not ideal for investigations."
"Updates are not coming out of preview quickly enough and it is holding back on the development of the product."
"The price, in general, could always be a little bit cheaper."
"I want Microsoft Defender to have the ability to deal with some issues automatically, so I don't need to address that issue manually."
"Microsoft Defender for Endpoint is secure but when it comes to security all solutions could improve security."
"Microsoft Defender in the basic form is not very useful for managing the security environment. The free version is not capable of covering the needs of centralized management, EDR, and behavioral analysis. If you don't have the commercial version, you can't have centralized management and set up the policies and other things. Each client is a standalone installation, which is not useful for security in an enterprise model."
"Microsoft has those capabilities as well, but you need a bit more training on the product to get the basic information that you can get out-of-the-box with Cortex."
"When you get the right person that knows what you are asking the first time, it is excellent. However, when you get someone who may be new or just switched into that role, it can be less effective."
"The performance utilization on the device that it's monitoring. This aspect needs improvement."
 

Pricing and Cost Advice

"The price for Microsoft Defender for Endpoint is about three euros, which is considered reasonably priced."
"This is an expensive product and licensing for all Microsoft products is a big issue."
"You don't need to worry about the renewal and purchase of antivirus products. It is bundled with Windows 10, so you don't need to worry about separately purchasing any antiviruses."
"We sell this product as part of Office 365 and it is not expensive."
"Microsoft Defender ATP is expensive."
"The solution comes free with Microsoft Windows 10."
"Given our extensive Microsoft licensing, transitioning to Defender for Endpoint did not affect licensing costs."
"You just pay Windows 10 prices, then you have antivirus software. As a price comparison, Defender's costs are very low."
"I would rate the pricing a three out of ten; one is very expensive, and ten is an absolutely cheap product."
