Palo Alto Networks was founded in 2005 by Nir Zuk, who had written the first stateful inspection engine at Check Point, and built the next-generation firewall — an appliance that identifies the application in a flow rather than judging it by port number. That product made the company, and it is now one of the largest security firms in the world, listed on Nasdaq, with around 16,000 employees and over 70,000 customers. Its range is organised under three names: Strata for network security and the PA-Series firewalls, Prisma for cloud and SASE, and Cortex for security operations — Cortex XDR for detection and response, Cortex XSOAR for automation, Cortex Xpanse for attack-surface discovery and Cortex XSIAM as the platform it is steering customers toward. Unit 42 is its threat intelligence and incident response arm. What appears in this index is the endpoint and firewall end of that portfolio. Its endpoint agent is sold as part of a platform rather than on its own, which is worth knowing when comparing its price and its test results with a standalone product's. Vendor page →
