How we tested Palo Alto's PA-4020 firewall
We spent two weeks putting the Palo Alto Networks PA-4020 through a series of tests designed to measure its capabilities. During our testing, the PA-4020 was connected to the Internet and was able to download virus, threat, and URL filtering updates.

Now in its forth year, the Jericho Forum has held the course in its role as a user forum advocating security alternatives to the perimeter firewall, arguing for its vision of "de-perimeterization" in an Internet-connected world of e-commerce and business collaboration. The group, though it's grown in membership, is gaining credibility but still manages to irk some critics who claim it's achieving little with its rhetoric.
