Features of Portmaster

1. Monitor all network activity: Discover everything that's happening on your computer. Expose any connections your application makes and detect bad ones. Finally have the strength to act accordingly.
2. Automatically block Trackers & Malware: Blocks ads, trackers, and malware hosts system-wide. Portmaster does this by default and uses a trusted filter list, which is also used by the Ad Blocker, etc. Easily change the defaults to suit your needs.

6. Set Global Settings & per app: Easily cut out apps from the Internet. Or block all p2p connections globally but allow them for certain applications. Or never connect to specific countries. Portmaster has you covered.
