Palo Alto provides great visibility into network threats
Palo Alto's PA-4020 is not just another firewall. Yes, it has what you'd expect in a basic firewall: 24 ports, divided into16 gigabit Ethernet ports and eight SFP ports. It has a rule base, some basic VPN capabilities, and a Web-based management interface. If the description ended there, Palo Alto would not likely make any headway into the enterprise firewall business which is already carved up between Check Point, Cisco, and Juniper.

UTM ¿ the buzzword Palo Alto won't cop to
The PA-4020 is indeed a unified threat management firewall, even if Palo Alto Networks would like to pretend it isn't. Because it's a firewall with integrated VPN, intrusion prevention and detection, URL filtering, anti-virus/anti-spyware, and file blocking, the PA-4020 fits squarely into the definition of a UTM firewall.

Is Palo Alto's firewall a firewall or not?
Palo Alto Networks has no illusions that a product on the market less than a year is going to have the feature set and depth that enterprise competitors Check Point, Cisco, and Juniper are offering. And, since most of the staff from Palo Alto are veterans from Check Point, Cisco, and Juniper, they were careful to design the PA-4020 so that it could be put behind (or in front) of an existing firewall at either layer 2 or layer 3.
