If you have a firewall you can block any external application from intruding on your Mac. However what can you do to monitor traffic coming from your Mac? Little Snitch informs you of all outgoing connections.
The latest version benefits from a significant redesign, which makes the information much more clearer and accessible. You can see what connection has been allowed or denied for each application, giving you a quick overview of outgoing connections. You can block applications from phoning home, which means contacting the internet without your consent.
Little Snitch lets you give permissions to certain programs, create rules and filters, add notes and search directly from the Little Snitch window. If you want more specific information on a particular connection you can even use the new Network Monitor. This will show all recent connections and the path to the given application.
In all, Little Snitch, is a very useful tool to monitor connections from applications on your Mac.
