  • Norton Personal Firewall
    Here is another great firewall from a reliable company. (If you act really quickly you can get this for $4.99 after rebate - no idea how long this will last!)

  • Sygate® Personal Firewall
    Here's another personal firewall solution that's free for personal use from the nice folks at Sygate®.

  • eTrust EZ Firewall
    You cannot go wrong with this product from Computer Associates. (You can download a free trial.)

  • myNetWatchman
    This firewall log event log analyzer is free for personal use, and best of all, it works in conjunction with ZoneAlarm™.

  • VisualZone 5.7
    From the developer: "VisualZone Report Utility is an intrusion analyser and report utility for ZoneAlarm and ZoneAlarm Pro. It displays a clear overview of all intrusion attempts and allows you to analyse the information in lots of different ways. VisualZone can perform a backtrace to try to find even more information about the intruder. You can even automate the process so that a backtrace is performed automatically when new attacks are detected. VisualZone can also submit intrusion attempts to DShield for further analysis."

  • Kerio Personal Firewall
    This is a very nice firewall, free for home and personal use.

  • LeakTest
    Does your firewall leak? Find out just how effective your firewall is with Steve Gibson's free program.
