# Fort (Firewall) Fort (Fort Firewall) is a standalone firewall for Windows that ships its own network driver rather than relying on the built-in Windows Firewall. It gives fine-grained, application-level control over network access. ## Key points - **App-level rules** — filter by address, port, and protocol, with wildcard support in application paths. - **Process-aware** — parent-process-based rule enforcement; service-name filtering for `SvcHost.exe`. - **Bandwidth control** — throttling per application group, traffic statistics, and graphical bandwidth visualization. - **Zones** — blocklist management via "Zones". - **Platform** — Windows 7+ (best on Windows 10 1809+), x86/x64/ARM64. - **Stack & license** — mostly C++ with C; Qt/QMake build; GPL-3.0. Actively maintained (200+ releases). A more feature-rich Windows firewall than the minimalist [[Simplewall (Firewall)]], and the Windows counterpart to Linux tools like [[OpenSnitch]]. ## References - Source code: https://github.com/tnodir/fort ## Related - [[Firewall]] - [[Simplewall (Firewall)]] - [[OpenSnitch]]
