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 free and part of the licensing stack of other Microsoft products."
"In Windows 11, Defender is very, very strong."
"This is the best feature of having OneDrive backup on the fly and recovery on the fly."
"It shows us the risky sign-ins, and if a user's password has been compromised."
"It captures data through machine learning, which is built-in on the back-end, and also provides built-in analytics and a threat intelligence feature, making it a one-stop solution that doesn't require an antivirus because it comes prebuilt into Windows 10."
"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."
"We are still navigating through it, and it has been working very well."
"What I like most is the protection against phishing emails and anti-spam."
"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

"If they integrate with the EDR then it will benefit this solution."
"The solution could be even more secure and provide an even higher level of security."
"This solution needs to move beyond relying on virus definitions alone and protect the system using behavioral analysis of the processes that are running."
"There could be an increase in security for the solution."
"There's a lot of manual effort involved to configure what we need."
"Microsoft Defender for Endpoint is a basic endpoint protection solution. If you do not combine it with another solution then you will leave yourself open to vulnerabilities."
"The central console needs improvement. Both McAfee and Symantec antivirus have dashboards. These integrate with a server and work on my antivirus or some other product. However, with Microsoft Defender, you use Microsoft Group Policy Object. Defender does not provide a central console. Therefore, if you implement Defender, then maybe use another tool for the central view."
"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 performance utilization on the device that it's monitoring. This aspect needs improvement."
 

Pricing and Cost Advice

"The E5 license is the one that I recommend because it comes with Cloud App Security, which is a good thing to have on top of Microsoft Defender."
"The product is free of charge and comes integrated into Windows."
"Licensing models of Microsoft are renowned for being complex. We just purchased the whole E5 stack. With E5 licenses for users, we get access to a bunch of features that are not just related to security. I would rate them a three out of five in terms of pricing."
"The solution comes as part of Microsoft Windows."
"Microsoft has different plans for buying this product. The price depends on the configuration of the full set of products that you buy and on the licensing program in your contract."
"We have the E5 security license, and the solution comes with that."
"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."
"The license for Microsoft Windows covers Microsoft Defender for Endpoint."
"I would rate the pricing a three out of ten; one is very expensive, and ten is an absolutely cheap product."
