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.

Quotes from Members

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

Pros

"The feature I like the most about Microsoft Defender for Endpoint is that it's built into Microsoft; the ASR rules have really secured our endpoints."
"Real-time detection and cloud-based delivery of detections are highly efficient."
"The solution is highly scalable."
"You can query and access useful information from logs and events, which is powerful and efficient."
"One of the best features of Microsoft Defender for Endpoint is called Threat and Vulnerability Management, TVM, which provides real-time visibility of vulnerabilities and misconfiguration at our endpoint level and helps prioritize and remediate based on risk information."
"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 solution has good performance, I have not seen a problem."
"The virus scanning capability is excellent, and it feeds all the logs into the Microsoft 365 Defender portal, making them easy to search for."
"The product integrates well with our systems, and we have not encountered any problems."
"All of the solution's features are quite valuable for us. We especially like the threat protection it provides."
"The Application Control code and the easy integration are valuable features."
"The most valuable feature is Click-time URL protection."
"Technical support is very responsive. You just have to open a ticket. They respond in a timely manner. Their response is good. I'm satisfied."
"It has certainly helped out our audit efforts because we each stay compliant in terms of various security standards."
"The most valuable feature is NetFlow threat protection."
"They manage to solve detection quite nicely. There is some rather elaborate detection compared to other providers."
 

Cons

"Microsoft Defender for Endpoint is secure but when it comes to security all solutions could improve security."
"I would like to see online updates for patches for this solution. I would also like to see online information about what is trending in the market in terms of spams, viruses, or trojans. It takes some time to understand how this solution works. A few things are unclear at the beginning, such as whether it actually restricts the virus or spam at the initial stage, or when there is a security update, how will we come to know and how will it get synchronized. It would be really helpful if there is some kind of knowledge base in the form of video, audio, or document that can explain in a user-friendly way the setup, features, risks, and process to mitigate the risks. Currently, I have installed endpoint security for every individual system. I could not install it like other endpoint solutions where we have a server and a client. It would be really helpful if Microsoft Windows Defender has a server-client based model so that I can save some bandwidth when it downloads or uploads features. It will be helpful if we have a LAN-based or WAN-based controlling system."
"It is inexpensive but could be cheaper like anything else."
"The product itself does not necessarily need improvement, but the support and implementation of the product are the disaster cases."
"Integrating this with third-party systems has some complexity involved."
"The initial setup can be a bit complex."
"Microsoft should improve support for third-party platforms, because not all functionality is available for all of them. It's a good product, but they should just extend the functionality for all platforms."
"Microsoft Defender for Endpoint is not as robust, and you cannot customize it much, so that's a challenge."
"Scalability could be better."
"They could enhance the solution to work across all devices, including Android, iOS, and Mac, and make it more user-friendly."
"The product's support services need improvement."
"The support has dropped down to a five out of ten."
"It should be able to collect information if the agent is disabled."
"The cloud platform needs to have improvement in terms of the user interface and the different capabilities it has available. It needs to match the other leading next-gen EDR products that are available in the market. That's the reason why we are stepping away from Symantec. Their cloud environment is just generally lacking in comparison to others."
"It's a strange situation where the infrastructure of the consumer or customer is behind some kind of firewall and they have always used some kind of customized proxy. In this situation, the ATP has a very tough time to pass the information to the cloud and back. To fix, it requires a more elaborate and complex configuration for that particular case."
"Symantec appliances need improvement. The whole appliance environment is a robust system and it needs a massive amount of storage space. If you have to increase or speed up the background storage it's a pretty complicated process. The scalability and sizing is critical, and if you do it wrong you run into issues pretty quickly."
 

Pricing and Cost Advice

"I got it with the Microsoft Windows license."
"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."
"When compared with other vendors, the pricing is very high."
"This is an expensive product and licensing for all Microsoft products is a big issue."
"Microsoft Defender for Endpoint is an expensive solution."
"Microsoft Defender is an expensive product in my country."
"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."
"Given our extensive Microsoft licensing, transitioning to Defender for Endpoint did not affect licensing costs."
"The price is quite expensive."
"Symantec Endpoint Protection has an average price."
"The pricing of this solution is inexpensive and affordable."
"Symantec Advanced Threat Protection's pricing is comparable."
"Pricing is good. It is nice to have a great product at a fair price."
