Palo Alto Networks - The Cybersecurity Reference Architecture

Founded in 2005 by Nir Zuk and headquartered in Santa Clara, California, Palo Alto Networks invented the next-generation firewall and is consistently named a Leader by Gartner across Network Firewalls, SASE, SSE and CNAPP. Three platforms - Strata, Prisma and Cortex - cover network, cloud and security operations end-to-end.

Why CISOs Choose Palo Alto Networks

Palo Alto's single-pass parallel-processing architecture classifies every packet by application (App-ID), user (User-ID) and content (Content-ID) - not just port and protocol. The result: precise, identity-aware, zero-trust policy at line rate. PAN-OS, Panorama centralised management, WildFire cloud-based malware analysis and Unit 42 threat intelligence form a tightly integrated stack trusted by 95 of the Fortune 100.

Pioneer of the NGFW - App-ID, User-ID and Content-ID classify all traffic in a single pass
Leader in Gartner Magic Quadrants for Network Firewalls, SSE and CNAPP
WildFire - cloud-scale ML & sandboxing analysing millions of unknown samples a day
Unit 42 - world-class threat intelligence and incident response on-call 24x7
SmartSoft PCNSE-certified architects - design, deploy and operate, with on-site support
