Audience
Windwall is for Windows users who want to see which programs on their PC connect to the internet and stop the ones they don't trust by using the firewall Windows already has. It suits privacy-minded home users, IT professionals who look after a handful of machines, and small businesses that want outbound control without adding a kernel driver or a second firewall.
About Windwall
Windwall is a control center for the Windows Firewall already built into Windows 10 and 11. It shows every connection your PC makes as it happens and blocks any program in one click, with real Windows Firewall rules rather than a second firewall engine.
A live log shows the program, address, port and protocol behind each connection. When an unknown program is blocked, a prompt asks: Allow or Block? Three security postures can be switched from the tray, and "Block with Windwall" in the Explorer menu blocks any program or folder. No kernel driver, no background service, no telemetry.
Windwall PRO is an optional one-time purchase that adds Shield (a malicious-IP blocklist and malware-filtering DNS), a per-app traffic monitor, connection history, a world map and much more.
Available in the Microsoft Store.
