I really don't see much value added by running both firewalls on the same host. In my experience, ZoneAlarm has done a great job monitoring both in and outbound traffic and should be sufficient (considering near-optimal management). Running a second firewall, such as the Windows Firewall, adds another layer of complexity, but not necessarily another layer of security. I just don't see it being efficient, from both a performance perspective, as well as from a security perspective.

Subject: Spam: Zonealarm+Windows Firewall
I have been using Zonealarm for many years. I've only started using Windows Firewall recently after upgrading my XP to SP2. I know that Windows Firewall only filters incoming packets (correct me if I'm wrong) thus I have kept my Zonealarm installed and running.
What is the implication of running both firewalls concurrently? Does Windows Firewall automatically take precedence over Zonealarm? Does this constitute a 2-tier firewall on my home PC?
I noticed that Windows Firewall does not notify me before dynamically adding new rules to allow traffic through. This concerns me greatly and I am contemplating turning Windows Firewall off and relying on Zonealarm. Any comments?
