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

"Microsoft Defender for Endpoint is scalable. Currently, we have 600,000 users in our organization."
"We had absolutely no issues with the stability of Microsoft Defender for Endpoint."
"The integration of Defender, Security Center, and the Microsoft compliance score, is the feature we use most to share the results with our clients and to create a roadmap together."
"Microsoft Defender for Endpoint has been leading the field in EDR, and there are so many benefits to how that is managed versus the traditional products; that's huge."
"We are a Microsoft shop, and Defender is a Microsoft solution that provides some security at a reasonable cost."
"Defender is stable enough and is competitive with the other products in the market."
"It's effective against most types of infection, and the firewall is perfect for protection."
"Provides good vulnerability assessment."
"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

"The UI for Microsoft Defender for Endpoint needs to be better. Integration with client dashboards is also lacking in this product, e.g. client dashboards shouldn't just be viewable from the cloud, because when the client's computer is offline, you won't be able to see the client dashboard."
"Integrating this with third-party systems has some complexity involved."
"The solution could use improvement on the interface."
"Sometimes, there are different skews. In a basic skew, they should have basic log analysis without the need to integrate with any third-party or SIEM solutions, like Sentinel. This would make it so much easier for users who don't have log collection or log analysis."
"I wish they would extend the use of the Security Central portal, even for the free option of Defender."
"Microsoft Defender for Endpoint's licensing is confusing. It has conflicting information on the website. We also faced integration issues with other systems. It makes laptops slower than traditional antivirus systems."
"The solution needs to improve its ransomware. It's not so good. It could also use some general performance optimization for the computers the solution operates on, to ensure it does not slow down the devices."
"The major area for improvement is the integration with a managed service provider."
"The performance utilization on the device that it's monitoring. This aspect needs improvement."
 

Pricing and Cost Advice

"The price was a problem for me three years ago, but they improved their E3, E5, and a la carte licensing. In other words, you have to get all of E5. That used to be a problem because you had E3, Defender, and guardrails, but you needed an E5 license to get the management suite and the analytics. It's more flexible now. You can switch from a la carte to the entire suite when it starts to make sense. It's becoming more economically competitive to go that route."
"Microsoft Defender for Endpoint is an expensive solution."
"The price is fair for the features Microsoft delivers. If you want tailor-made features, you have to mix different licenses. It isn't straightforward."
"We went for Microsoft Defender once we were informed that it would be part of our Office 365 package. So, we combined the licensing for the OS with Office 365. Yeah. We thought it was a good bargain."
"Microsoft Defender ATP is expensive."
"The subscription is part of Windows, so we don't have to pay anything extra for this product."
"The solution comes as part of Microsoft Windows."
"The license for Microsoft Defender for Endpoint is included in the license for the Microsoft Windows operating system."
"I would rate the pricing a three out of ten; one is very expensive, and ten is an absolutely cheap product."
