Palo Alto Networks PA-500 - security appliance

Palo Alto Networks PA-500 is a next-generation firewall appliance for enterprise branch offices and midsize businesses. The controlling element of the PA-500 is PAN-OS, which natively classifies all traffic, inclusive of applications, threats and content, and then ties that traffic to the user, regardless of location or device type. The application, content and user - in other words, the business elements that run your business - are then used as the basis of your security policies, resulting in an improved security posture and a reduction in incident response time.
