It blocks the things which are not to be allowed. It has an adaptive mode where it learns for itself.

It is a good central viewpoint for issues. These can then be investigated in more detail on the subnet server(s)/endpoints.

The most valuable feature is that if the scanning does find something, it quarantines it. Then you can decide what you are going to do with it.

Yes, sometimes it seems that versions with major upgrades come with some bugs and regressions that affected stability.

The disk space needed for events is not clear. In all clients, we had at least more than 100GB free that we could not use.

The product documentation is good, but could be better. Also a bug-free version would be nice as the version I worked on had a bug in the alarm system.

Executives don’t see ROI on this solution as the reports are not meant for C-levels.

There are always multiple bugs in the product. For example, the console page was hanging multiple times. Afterwards, they released multiple upgrades for the same, multiple patches from McAfee.

The only issue I have with McAfee is the amount of computer resources that it takes... it's definitely impacting some of the other applications that are running on a computer at the same time.
