Well there are plenty of threads about the best AV, but what about the best Firewall? Personally I'm using Comodo Firewall, but for a client I recently purchased a Cisco RV220W router which comes with a built in firewall. While I've done a little pentesting on Comodo and it's held up decently, I have not tested out the Cisco router I recently bought (when I do I'll update the thread). Although as the title suggests I am asking SL a question, so what is your preferred firewall?
