Hello my name is Samuel Chávez, i am from Nicaragua and use Comodo firewall pro in Spanish but i considere that it needs a password protection when an administrator is using a pc with administrator privileges because another person can use this account and turn off the firewall protection, this is an important feature to protect the system stability (Comodo password protection). However i think Comodo is the lord of the firewllas in the market currently. you need to improve the interface too!
Welcome to the forum, Mr. Chávez.
Both of them are already in CFP 3, currently in beta testing.
