GlassWire isn't a replacement for an antivirus. I think the only way to see all network activity is by tapping into the wire itself. I made GlassWire to give myself an easy way to see what my computer was doing in the background but I do understand there are always going to be ways to bypass it along with any other application.

I'm not sure you are clear on what distinguishes a host based intrusion detection system, network based intrusion detection system, and antivirus. The feature list you are advertising sounds like a NIDS and HIDS, well known security software used in any secured network. I realize your software isn't antivirus like Norton or ClamAV. I am suggesting you might not be familiar with popular open source software that seems to accomplish your same feature set that large companies often use.

Intrusion detection systems are in a different business. They use stats or fingerprints to flag bad traffic/behaviour, then log alerts. Glasswire is an inspection tool to see what apps are doing net traffic wise on your computer.
