Little Snitch is a Mac OS X app that runs in the background and hooks with the kernel. As the name indicates, Little Snitch warns you when an application tries to make a network connection, asking you to decide if you allow, deny or add a permanent rule for that specific app in future connections.
A good amount of information on the connection being made is presented to the user, and on version 2 (still in beta), besides the improved network filtering, a visual Network Monitor has been implemented, allowing the user to have real time access to the connections as well as some some send / receive icons like Zone Labs’ Zone Alarm. The configuration interface has suffered some changes and it’s now more functional and user friendly than the previous version.
