I'm about to rework a couple networks I manage, and I'm looking for a firewall to complete the security mix. I use NOD32 and am about to replace Aluria AntiSpyware with Ewido. I am looking for something that should coexist happily with those programs. I've tried Outpost and ZoneAlarm in the past; Outpost was ok and ZoneAlarm didn't really move mountains for me. Given the people who will be using these computers, the easier and more transparent things are, the better.
