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 Features:

Network Monitor
GlassWire's network monitor visualizes your current and past network activity by traffic type, application, geographic location, all on a beautiful and easy to understand graph. Go back in time up to 30 days and see what your computer or server was doing in the past. Click the graph to see details of what app or network event caused a spike in network activity.

Threat Monitoring
GlassWire reveals hosts that are known threats, unexpected network system file changes, unusual application changes, ARP spoofing, DNS changes, and alerts you to the problem so you can take action. GlassWire can also remotely monitor and help protect servers or other computers far away. Install GlassWire on your server or remote PC and look out for unexpected threats or problems. If you see unexpected activity you can block it with GlassWire’s free firewall.
