About Fort Firewall
Fort Firewall is a standalone firewall for Windows 7 and later that controls network access per application or globally by addresses, ports and protocols. It supports wildcards in application paths, parent-process based rules, filtering by SvcHost service names, speed limits for application groups, and blocklists organized into zones.
It saves traffic statistics and shows bandwidth graphically, running on its own driver rather than relying on the built-in Windows firewall. It suits users who want fine-grained control over which programs may connect to the network.
