Palo Alto Networks

Palo Alto Networks invented the concept of the application-layer next-generation firewall (NGFW) and has since grown into one of the largest pure-play cybersecurity vendors in the world. Their product universe spans three major platforms: the PA-Series hardware firewalls (from branch to hyperscale chassis), Prisma (SASE/ZTNA/cloud security posture management), and Cortex (AI-driven XDR, XSOAR SOAR, and Xpanse attack surface management). PAN-OS, the operating system across all NGFW hardware, is known for its comprehensive App-ID and User-ID policies which replaced legacy port-based ACLs as the standard for enterprise perimeter security. Consistently positioned in the Leaders quadrant of the Gartner Magic Quadrant for Network Firewalls.
