Palo Alto Networks was founded in 2005 by Nir Zuk, a former Check Point and NetScreen engineer, in Santa Clara, California. Zuk’s idea was to build a next-generation firewall that could identify applications regardless of port, protocol, or encryption — a significant advance over traditional port-based firewalls.
The company went public on the NYSE in 2012 and has grown through a combination of organic development and aggressive acquisitions. Notable purchases include Demisto (security orchestration, $560M), CloudGenix (SD-WAN, $420M), and Bridgecrew (cloud security). These acquisitions helped Palo Alto Networks build a broad security platform.
Today, the company operates three main platforms: Strata (network security), Prisma (cloud security), and Cortex (security operations). The Strata lineup includes next-gen firewalls, while Prisma Cloud handles cloud workload protection and Cortex XSIAM provides AI-driven security operations.
Annual revenue surpassed $6.9 billion in fiscal year 2024, making Palo Alto Networks one of the highest-revenue cybersecurity companies in the world. Under CEO Nikesh Arora (former SoftBank president and Google executive), the company has pushed a “platformization” strategy — encouraging customers to consolidate their security tools onto Palo Alto Networks’ integrated platform.
The company serves over 80,000 customers, including most Fortune 100 companies. It employs more than 14,000 people worldwide with headquarters in Santa Clara. Palo Alto Networks’ market cap regularly exceeds $100 billion, reflecting its position as a dominant force in enterprise security.
