"Beats any other firewall!"
The new version (2.0) is heaps better than the previous version. In fact you can argue its better than any other firewall - and its free. It passes all leaktests unlike the free versions of ZoneAlarm and Kerio and offers advice about whether an application should be given internet access or not. It is very simple to use - great GUI and colour scheme. And it has a lifetime license!
