Next-Generation Firewalls (NGFWs) and Cloud Access Security Broker (CASB) solutions rely on deep-packet inspection to maintain visibility into modern network traffic. Palo Alto Networks revolutionized this approach through App-ID, a technology that enables granular application-level inspection beyond simple port and protocol blocking. Their software helps organizations stay ahead of complex, evolving application landscapes by integrating machine learning to enhance the accuracy and coverage of App-ID. By automating the identification and control of applications, Palo Alto Networks helps security teams enforce consistent policies, reduce the attack surface, and gain unprecedented insight, ensuring robust protection for distributed, cloud-native enterprise environments.
