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

"Defender is stable. The performance is good."
"Microsoft Defender for Endpoint gives us a second layer of security as well as the third layer of security."
"Defender for Endpoint has one dashboard with security-related information, vulnerability-related information, and basic recommendations from Microsoft, all in different tabs. That's helpful because if we want to fix only the recommended ones, we can go fix all of them..."
"I like that it's easy to deploy because it already comes with Windows 10. Overall, it has all the features that we need. Easy to deploy, comes with updates, and comes with Windows updates. You don't have to really manage or update the signature."
"A few years ago, when I was using a different product, I was affected by a virus that destroyed everything. Since using Microsoft Defender, I have not had this kind of problem."
"It can reach our applications and PC activities in the cloud."
"The automatic attack disruption feature in Microsoft Defender for Endpoint works great."
"It automatically detects intrusion and malware."
"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 would like to be able to set up any kind of protection I want in the firewall, any IP address or any number."
"We'd like to see integrations with more vulnerability scanning solutions like Tenable."
"Microsoft Defender for Endpoint is secure but when it comes to security all solutions could improve security."
"A single dashboard would be a significant improvement."
"Microsoft Defender for Endpoint could provide us with a more holistic approach, such as collaboration. They can provide us with an environment from where we can manage all the endpoints from one central location, such as overall management."
"Microsoft Defender for Endpoint should include better automation that will make it faster to detect the latest threats happening across the world."
"The integration and effectiveness of email security could be better. It's already built-in to the solution and checks emails, scans the links they contain etc."
"Service Requests. Noncritical cases with MDE technical support teams tend to be queued for over a week before the first customer engagement."
"The performance utilization on the device that it's monitoring. This aspect needs improvement."
 

Pricing and Cost Advice

"The solution comes free with Microsoft Windows 10."
"The license cost is around $35 per machine, which is not expensive compared to other products."
"The solution is free with Windows."
"The price for Microsoft Defender for Endpoint is about three euros, which is considered reasonably priced."
"Licensing fees are paid annually through a partner."
"This solution is part of an enterprise license we have."
"It's all pretty easy. For some clients, it's an easier sell because it's just an add-on to their existing Microsoft licensing and Office 365 licensing."
"We have an enterprise agreement so from my perspective, this is a product that ships with Windows and it is not priced standalone."
"I would rate the pricing a three out of ten; one is very expensive, and ten is an absolutely cheap product."
