Safing Portmaster

What is Safing Portmaster?

Portmaster shows network connections by application so you can investigate where your Windows programs connect and decide what to allow. It combines a connection monitor with configurable filtering: block an individual connection, restrict an application's internet access, or define rules globally instead of repeating them for every program. Domain, IP and country-based rules help narrow the traffic you want to permit.

The local privacy features include filter lists for ads, trackers and malware hosts, plus encrypted DNS through configurable resolvers. This is useful when you want filtering beyond a browser extension, including background applications. Network history, bandwidth visibility and the Safing Privacy Network (SPN) are paid features; the free firewall should not be confused with a free IP-hiding service. The screenshot shows an interface with SPN enabled, not the entitlement of the free download.

This entry links to the publisher's Windows x64 EXE named Portmaster_2.2.8_x64-setup.exe. Safing's v2 installation guide says the installer is for initial installation, subsequent updates are automatic, and Portmaster does not start automatically immediately after installation. The Core service is configured to start on boot. The same guide supports only 64-bit CPUs; it does not specify a minimum Windows build. To remove Portmaster, use Windows system settings or its installed uninstaller; the guide recommends rebooting afterward.
