Open source cross-platform network activity monitor.
Unwanted connections, trackers, and background traffic can be difficult to identify and control on a busy Windows system. Portmaster 2.2.1 is an open-source network monitor and privacy firewall that lets users review application activity, manage connection rules, and apply filtering settings across apps.

What's new in Portmaster 2.2.1:
- Connection details now show “SPN Tunnel” only when traffic was actually routed through SPN.
- Fixed application profile migration when application fingerprints changed.
- Fixed Linux connections that existed before Portmaster started or resumed bypassing SPN routing rules.
- Improved Linux compatibility with IVPN Client in certain environment configurations.
- Added split tunneling so selected applications can use a different network interface.
- The main dashboard no longer displays usernames as a privacy improvement.
