The problem I have with Glasswire and similar products is that you can make calls through other Windows APIs (I don't know if that's the correct term for this but you get the idea). Especially if you run it as administrator. That means that if they want they can hide themselves from the firewall tab (the standalone .exe I mean) and make calls that will only show in other places like System or Internet Explorer. Hard to monitor or manage that.

I hope they do something about this in the new version of Glasswire that is about to be released.
