Are there any sites available that compare and test firewalls on a continuous basis? I have been a long time user of Sygate Personal Firewall and Pro version. But with some of the sites I use to do a security check on my pc it doesnt show on a regular basis that UDP ports 53 and 137-139 are closed/stealthed. I am currently in a toss up between 3 firewalls - Agnitum Outpost Firewall Pro, Tiny Personal Firewall 4.0 and Kerio Personal Firewall 3.0 Beta 5. These 3 firewalls I like very much and they report those ports mentioned above closed/stealthed on a regular basis for the port scan on Broadbandreports.com. No firewall I try shows those mentioned ports above closed on the Sygate site. Why do I get a different result with each security scan on these sites? Are their scans they perform different? Is there a firewall that is really good at providing IPs for every connection and port open/connected to? The 3 firewalls I am in a toss up between are fairly decent, but not as good as I would like. If there isnt a firewall which is good at this, is there an extra piece of software I can download that would do this job and do it well?
