Mac OS X firewall software

I was searching for a firewall app for my Mountain Lion, because I’m not really satisfied with the default OSX firewall option in System Preferences. For me it lacks customization. On a security presentation I asked the presenter and introduced me to a paid firewall app ‘Little Snitch’ which is very nice and full of cool features. I continued to search if some free app exists and found IceFloor which is a frontend interface for the OSX built in firewall, PF – Packet Filter. For older OSX than 10.8 there is WaterRoof
