Like you, I haven't used the Agnitum Outpost but that's because I haven't needed to. Others such as ZoneAlarm work fine for me. Rule-based systems allow you to configure trusted ports where you will allow traffic for specific programs. In most cases, they set up "rules" before using the system. Program/permission based systems allow you to configure access for trusted programs through the firewall. In essence, they're doing similar tasks, but in a slightly diffferent graphic user interface.
Read the reviews. Although not bad, Outpost is not always one of the favorites.:
PC Personal Firewalls 2004,
Personal Firewall Reviews
Outpost Firewall Pro ... Version: 2.1
Hope this helps.
I've been thinking this over for ages, but I need advice.:)
I posted this in another forum, but I don't actually trust it because I don't think they are experienced users. I know that the users here are techies.
The main question is, "Which is better? Agnitum Outpost Firewall Pro or ZoneLabs' ZoneAlarm Firewall Pro?"
The only firewalls that I tried are Sygate Personal Firewall, ZoneLabs' ZoneAlarm Firewall, and the Pro version. And those are all permission-based. They say that Agnitum Outpost is port-based? What's that? Please, I'm desperate! Thanks in advance!
