The software is still in early stage of development, and alpha quality software, don’t rely on it (yet) for your computer security. However, this software can be very useful for Linux desktop users.

OpenSnitch is an application level firewall, meaning then while running, it will detect and alert the user for every outgoing connection applications he's running are creating. This can be extremely effective to detect and block unwanted connections on your system that might be caused by a security breach, causing data exfiltration to be much harder for an attacker.
