Our Palo Alto Networks firewalls classify network traffic by the application’s identity in order to grant access to users and provide visibility and control of all types of applications to admins, including web applications, software-as-a-service (SaaS) applications and legacy applications. Our approach uses the application, not the port, as the basis for all your safe enablement policy decisions so you can allow, deny, schedule, inspect and apply traffic-shaping. When needed, you can create custom App-ID™ tags for proprietary applications or request App-ID development for new applications.
