Gained AI visibility and now control sensitive data and shadow usage across our organization
The best features CrowdStrike Falcon AI Detection and Response (AIDR) offers are that it tells us the token usage and provides us the capability to protect it, such as any PII data, we can mask it, block it. We can do all that within the product. The most valuable feature for my team has been the PII data because sensitive data leaving our company to the GenAIs is probably not acceptable. It gives us control. CrowdStrike Falcon AI Detection and Response (AIDR) has positively impacted my organization by providing insight into all types of AI usage, LLMs, and everything under shadow AI, which allows us to protect our data and govern our policy. It has improved compliance because we can now put controls around our company policy.

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.

"It is very valuable to secure AI activity through the same platform I use for endpoint, identity, cloud, and data security."
"The virus scanning capability is excellent, and it feeds all the logs into the Microsoft 365 Defender portal, making them easy to search for."
"We are a Microsoft shop, and Defender is a Microsoft solution that provides some security at a reasonable cost."
"In Windows 11, Defender is very, very strong."
"Threat intelligence is one of the most valuable features in Microsoft Defender for Endpoint."
"If anyone is looking for an antivirus instantly, they can enable Microsoft Defender for Endpoint on their Windows operating system."
"It doesn't cause the slowness of the system, which is one of the reasons why I like it."
"Microsoft Defender for Endpoint is a very good solution."
"We had some problem and, after four hours, we had new signatures for the environment by our customers for more than a thousand clients so that we can protect and improve the new setup."
 

Cons

"Regarding improvements for CrowdStrike Falcon AI Detection and Response (AIDR), the UI is not that great and is a little slower."
"It is a usability issue that I cannot easily get back from CrowdStrike Falcon Guardian (AIDR) to Endpoint Protection via the hamburger menu."
"I have not seen a return on investment yet as we are only two months into it."
"CrowdStrike looks to be the market leader, but it is too early for us to say."
"Some competitors are working in different areas, covering different risks, and the product is not yet compatible with Mac OS devices, which is disappointing."
"The main overview with the honeycombs is not very effective."
"I evaluate CrowdStrike support as very basic, which presents some challenges, but we are in discussions with our account manager about potentially moving to Support Elite."
"Data visualizations are a little lacking right now with CrowdStrike Falcon AI Detection and Response (AIDR)."
"Sometimes, there are difficulties in downloading a file considered as malicious."
"Cortex... has good investigation capabilities, out-of-the-box, in case there is an event that you'd like to investigate. It's quite convenient. 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."
"It could be easier when it comes to managing exceptions."
"The dashboards could be better."
"On the Mac OS platform, there is no parity between Windows and Mac OS. The solution is very feature-rich and very well-integrated into Windows, and I guess baked into Windows 10 and Windows 11. Whereas, on the Mac OS platform, there is still some work there to give it a more feature-reach platform."
"I would like to be able to set up any kind of protection I want in the firewall, any IP address or any number."
"Windows Defender, which is just a free version, is not as effective. It doesn't have deep support or deep protection."
"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."
 

Pricing and Cost Advice

Information not available
"Microsoft Defender ATP is expensive."
"We have the E5 security license, and the solution comes with that."
"We have been using the free version."
"Pricing for Microsoft Defender for Endpoint is competitive. Out of the bundle, you will get a lot of security, if I talk about Microsoft E5, for example, and get a lot of benefits. If the customer goes and purchases a different solution, it will cost more, so pricing for Microsoft Defender for Endpoint is quite reasonable at the moment. There isn't any challenge in terms of pricing, for example, I didn't see a customer who pulled back because of the price. Some prices could be negotiable, and sometimes, as a sales point, the two become negotiable, but they don't bill one and pull back because of the pricing. If you have an E5 license, you get everything."
"The price is higher than others because it is doing more than what the others are doing."
"The licensing costs for Microsoft Defender for Endpoint are reasonable."
"For most people, the price of the license is not something that they have to worry about."
"Pricing can always be lower."
