Symantec Endpoint Security Enterprise needs user-friendliness upgrades, better Mac compatibility, and improved pricing, threat notifications, and support services.
Repeated interactions are necessary due to Level One's lack of tools and knowledge, hindering efficient problem-solving and negatively impacting our experience with Microsoft support.

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.

Provides stable and resource-efficient protection but lacks clear modern security features
Symantec Endpoint Security Enterprise is highly compatible and rarely causes disruptions in production. It operates transparently and is easy to maintain. The automated response feature helps to mitigate breaches effectively. When comparing with ThreatDown agent, I have noticed that ThreatDown detects behaviors more readily and flags suspicious user activities more clearly. While Symantec Endpoint Security Enterprise remains effective, ThreatDown's user interface is more manageable and provides a clearer system overview. The management interface is crucial for maintaining Symantec Endpoint Security Enterprise effectively. A significant advantage of Symantec Endpoint Security Enterprise is its lightweight resource usage. It consumes less memory, CPU, and IO compared to alternatives such as ThreatDown and Bitdefender.
