Palo Alto Networks’ next-generation firewalls provide network security by enabling enterprises to see and control applications, users, and content – not just ports, IP addresses, and packets – using three unique identification technologies: App-ID, User-ID, and Content-ID. These identification technologies, found in Palo Alto Networks’ enterprise firewalls, enable enterprises to create business-relevant security policies – safely enabling organizations to adopt new applications, instead of the traditional “all-or-nothing” approach offered by traditional port-blocking firewalls used in many security infrastructures.
