I am looking to find the best firewall with a good balance of Quality / Features with it being not heavy on resources. It need not be the LIGHTEST or SMALLEST, but if its decent enough from that stand point. The last that I remember using a Personal Firewall was TinySoftware Firewall a LONG TIME AGO. I liked it back then - It was clean, light, efficient, fast... But ofcourse this was a LONG TIME ago. So lets update ourselves. Maybe we can use the following parameters (SOMEONE PLEASE FEEL FREE TO ADD MORE - At this point this is all that I could think of) 1. Name 2. Price - $$, Free, Shareware, ~Off topic comment removed.~ 3. Version 4. Memory Footprint 5. VM Footprint 6. Typical CPU % / cycles 7. Typical Slowdown of user experience 8. Rules Management System 9. Alert / Flagging System Score - True Positives v/s False Positives 10. Overall user experience etc.. I read 2 year old thread on firewalls here https://www.wilderssecurity.com/showthread.php?t=94382 and I could not reply there so I had to create a more updated topic. ~Link to rogue site removed. Not recommended by Wilders. - Ron~ Also read this 2007 review of personal firewalls. I have no idea how VALID it is, but I am adding it for reference.
