The core of the Palo Alto Networks enterprise security platform is a next-generation firewall that identifies all traffic, inclusive of applications, threats and content, then ties that traffic to the user, regardless of location or device type. The application, content, and user, the business elements that run your business, can then be used as integral components of your enterprise security policy.
