Palo Alto Networks is a cybersecurity company that helps enterprises, governments, and service providers protect their networks, cloud environments, and IT infrastructure from cyberattacks. The company organizes its products into three platforms: Network Security, Security Operations (Cortex), and Threat Intelligence (Unit 42). Network Security is the largest business and centers on next-generation firewalls (NGFWs) in both hardware and software form factors, as well as SASE (Secure Access Service Edge), which secures remote workers and branch offices via a cloud-delivered solution. The Cortex platform is Palo Alto's AI-driven security operations business, anchored by XSIAM, an AI-powered SOC platform that replaces traditional SIEM tools by ingesting and correlating data across endpoints, networks, cloud, and identity sources to automate threat detection and response. Unit 42 is a professional services business offering incident response, threat research, and security consulting. Palo Alto sells primarily through distributors and resellers, supplemented by a direct sales force on large accounts. Revenue comes from hardware firewall sales, recurring software subscriptions, and support contracts, with subscriptions being the fastest-growing stream. The company's core strategy, which it calls "platformization," encourages customers to consolidate multiple security point products onto Palo Alto's platforms, resulting in larger, stickier, multi-year deals with high net retention. In July 2025, Palo Alto announced an agreement to acquire CyberArk, the leading privileged access management company, to expand into identity security.
