Palo Alto Networks
Palo Alto Networks (NASDAQ: PANW) is a publicly traded SIEM / SOC & Detection company founded in 2005 and based in Santa Clara, United States.
Founded in 2005 by Nir Zuk, Palo Alto Networks pioneered the next-generation firewall and has since consolidated its portfolio into three platforms: Strata for network security, Prisma for cloud security (Prisma Cloud, Prisma SASE), and Cortex for AI-driven security operations (Cortex XSIAM, XDR, and XSOAR). The company has pursued an aggressive 'platformization' strategy backed by acquisitions, including AI-security startup Protect AI in 2025 and the roughly $25 billion acquisition of identity-security leader CyberArk, which it completed in February 2026. Cortex XSIAM positions Palo Alto as a major player in the AI-powered SIEM and autonomous SOC market.
Its Cortex XSIAM push and CyberArk acquisition make it one of the largest forces reshaping the SIEM and security-operations market around AI.
