Just as a little background on me, I'm a system admin at an ISP and recently one of our customers asked for help with Zone Alarm free version. After downloading the free version to a test machine, it provided DECENT security over both a LAN and from the internet. However once I executed a port scan from a remote computer I was able to not only detect open/closed ports but Zone Alarm did nothing to stop my intrusion once I started. The overall security from a "script kitty" seems to be quite good, but from another point of view I was able to get past the security in under 10 minutes and gain full access to the machine that had Zone Alarm installed. Overall I would recommend this to the average user but for serious security nothing beats a BSD hardware firewall.
