Windwall is a control application for the Windows Firewall included with Windows 10 and Windows 11. It operates from the system tray and writes directly to the native firewall through supported platform APIs, so each rule it creates is a genuine Windows Firewall rule enforced by the operating system itself. The program displays a live connection log where every inbound and outbound connection appears in real time with the responsible process, PID, remote address, port and protocol. Allowed traffic is marked in green and blocked traffic in red, and any row can be turned into an allow or block rule with one action. Three security postures, High, Medium and Low, are switchable from the tray and apply across the Domain, Private and Public profiles at once. Additional capabilities include full management of native firewall rules, a “Block with Windwall” entry in the Windows right-click menu, and light and dark themes. The core version is free, with no ads and no account, while an optional lifetime Pro key adds the Shield blocklist, malware-filtering DNS, a per-app traffic monitor with data limits, searchable connection history and rule collections.
