hi guys please post u r experiences regarding ur use of firewalls.i was using zonealarm for along time .its simple and anovice user dont need to mug up those help files whwich are bulky. off late i tried sygate and kerio too.kerio is simpler too.sygate offers u more options and is a bit complicated for the novice. but ifound it really good.also it hogs up very little memory when compared with other 2.kerio has a simpler interface , has this application monitoring facility thru which it monitors a change in application behavior even when u are offline. thats really good in detecting trojan horses and viruses.so it will compliment an antivirus in this regard. but the dis adv is that it hogs up more memory than the above 2.i think zone alarm has got some compatibility issues with some softwares but it still is good. i hope nobody has posted about firewalls recently. i didnt find any. inviting u r coments in this regard. also tell us about other firewalls that u guys have found useful.
