GlassWire (version 3.3.504.0) is a network monitoring tool that visualizes your current and past network activity on a graph, pinpointing any unusual activity that could indicate malware or violations of your privacy. It offers a firewall, which aids in blocking connections to your computer that you may not want. The software also provides alerts about hosts that are known threats, unexpected network system file changes, odd changes to your PC, or newly installed apps that could be suspicious. It can also monitor other PCs on your network and provide alerts if unknown devices join.
