Hi guys! I used Zone Alarm 2.6 for maybe 6 months . Liked it alot but just got bored with it after awhile. Especially after hearing about firewalls like Tiny,Sygate which you could configure the rules yourself for higher security. It still is a good basic free firewall for the newbie who doesnt want to mess with rules though. Used Tiny for just a short time & learned alot from it on how to create rules & learning about ports & protocols. It was a great education . But then the development team from Tiny left & created Kerio. Liked Kerio because the layout & simplicty was the same as the former Tiny one had. Used every beta ver of Kerio now up to 2.14 & love it. The new 3.0 beta of Kerio is out now but as Crockett has mentioned it isnt yet ready to fly . Its still to early to really use much because it is so early in the beta stage & some functions are disabled yet. When beta 2,3 come out though it should really get exciting. Kerio 2.14 is still awesome in my opinion for anyone to use yet if you want a really good rule based firewall + its free. Other very good rule based firewalls to try in my opinion are: - Visnetic (author was the creator of Conseal firewall) - Looknstop - Sygate - Zone Alarm plus Outpost may be good if you want your firewall taking care of cookies, ads, blocking spyware ect. I find programs like Proxomitron, Ad-aware take care of these things just fine plus there free.
