Palo Alto Networks' Next-Generation Firewalls
Palo Alto Networks' next-generation firewalls enable enterprises to identify 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 allow enterprises to securely enable application usage using business-relevant concepts, instead of following the traditional "all-or-nothing" approach offered by traditional port-blocking firewalls used in many security infrastructures.
Core Technologies

App-ID
Classify all traffic, on all ports, all the time - irrespective of protocol, encryption or evasive tactic.
|

User-ID
Securely enable applications on your network based on users and groups - not just IP addresses.
|

Content-ID
Real-time content scanning blocks threats, controls web surfing and limits data and file transfers.
|
Platforms
Purpose-Built Appliances
Delivered as a purpose-built appliance, every Palo Alto Networks next-generation firewall utilizes dedicated, function specific processing that is tightly integrated with a single-pass software engine. This unique combination of hardware and software maximizes network throughput while minimizing latency. Each of the hardware platforms supports the same rich set of next-generation firewall features ensuring consistent operation across the entire line.
