Top notch

I started using Comodo firewall (Pro) way back in 2007 at its early inceptions. I have not looked back since then. It has been so robust and protective! As an IT Pro, it gives me peace of mind; that is exactly what I need. I can allow and deny applications, connections any time by a click of the mouse! Comodo Firewall is the best so far notwithstanding the fact that it is indeed free!


This product is simply awesome! The new version 8.2 is light on system resources and can be fully configured in order to be your pefect internet companion. I suggest to disable the HIPS (in order to have more usability) and to activate the autosandbox feature!
