GlassWire

You'll be shocked by how many applications on your computer are sending your private data over the Internet without you knowing. GlassWire's free firewall and network monitor helps protect your privacy & security by monitoring your network activity for suspicious activity. Once suspicious activity is detected you can block the potential threat with GlassWire's built in firewall management tool.

GlassWire visualizes all your network activity on an easy to use graph. Click anywhere on the graph to see what applications and hosts are accessing the network from your computer. Our software automatically resolves host names so it's easy to see who or what your computer is communicating with over the Internet. Go to the Firewall tab to see what applications have accessed the Internet and block any that are suspicious, violating your privacy, or wasting your bandwidth. GlassWire uses Windows built-in firewall so no instability is introduced into your system by third party firewall drivers.
