Monitor All Network Activity

Discover everything that is happening on your computer. Expose every connection your applications make and detect evil ones. Finally get the power to act accordingly.

Block Domains

Many programs connect to the Internet without your knowledge. When you find unwanted connections, you can now simply block them.

Automatically block ads, trackers and malware hosts via trusted domain-lists, which are also used by Ad-Blockers, etc. Easily change the defaults to fit your needs.
