What key capability distinguishes Content-ID technology from conventional network security approaches?

Content-IDis the core of Palo Alto Networks' prevention architecture, providingsingle-pass application layer inspectionto deliver real-time threat prevention across all traffic.

“Content-ID uses a single-pass architecture to perform application-layer (Layer 7) traffic inspection and real-time threat prevention. Unlike traditional firewalls that rely on multiple scans, Content-ID inspects traffic once to enforce multiple security controls simultaneously.”

By consolidating security functions in a single pass, it ensures both efficiency and comprehensive security.
