PrivateFirewall

It's a firewall between the lightest in circulation: it is not based on the recognition of digital signatures, as the behavior of programs. Requires, when you start a program for the first time, allowed his execution, if this program can be allowed access to the Internet (with more detailed configuration options).

It also possible, by configuring PrivateFirewall, IP block access to undesirable or even to websites that we want (simply by adding the site URL to the list of block).

Thus it would seem an excellent product, however, when you go to do some more targeted testing, you notice some flaws. There are in fact of the vulnerability tests that other firewall (like Comodo Personal Firewall, for example) easily overcome, but PrivateFirewall not (at least so far) able to overcome.

Its use is free for both private and commercial purposes.

Overall not a bad way firewall, but when we have free firewalls that are more powerful and complete (Comodo, Outpost Free, Online Armor).
