Nir Zuk founded the company in Santa Clara in 2005 after engineering stints at Check Point and NetScreen, where he had built early stateful-inspection and firewall technology. His thesis was that firewalls had gone blind: they could no longer see which applications or threats were inside traffic. Palo Alto Networks' first product, shipped in 2007, was the next-generation firewall, which identified and controlled applications and content rather than just ports and addresses.
The next-generation firewall concept won the enterprise market against incumbents Check Point, Cisco, and Juniper. The company went public in July 2012 and grew into the largest security vendor by appliance and network security revenue.
Mark McLaughlin led the company as CEO through the IPO era until Nikesh Arora arrived in 2018 with a platform consolidation strategy: customers were drowning in point products, and Palo Alto would sell integrated platforms instead. A $15 billion-plus acquisition spree followed, building three platforms: Strata for network security, Prisma for cloud security, and Cortex for security operations including the Cortex XDR detection product and Cortex XSIAM autonomous SOC platform.
The acquisition pace accelerated under AI-era pressure. Notable deals included Twistlock, PureSec, Evident.io, Zingbox, Expanse ($1.35 billion), Bridgecrew, and in 2023-2025 a return to mega-deals: IBM's QRadar SaaS assets, the $3.35 billion Chronosphere observability acquisition announced in late 2025, and the landmark $25 billion CyberArk acquisition completed February 11, 2026, the largest security deal in the company's history and one of the largest ever of an Israeli company.
Fiscal 2025 revenue reached $9.22 billion, up 15 percent, with Next-Generation Security ARR of $5.58 billion. Fiscal 2026 revenue was approximately $11.5 billion, lifted by CyberArk's contribution from February onward and continued platformization. The company surpassed a $10 billion revenue run rate and set a goal of $15 billion in NGS ARR by 2030.

What companies has Palo Alto Networks acquired?
Major deals include CyberArk (~$25 billion, 2026), Chronosphere (~$3.35 billion, 2025), Expanse ($1.35 billion, 2020), IBM's QRadar SaaS assets (2024), plus Twistlock, Demisto, Zingbox, Bridgecrew, Talon, and dozens of others.
What does Palo Alto Networks sell?
Four platforms: Strata for network security, Prisma for cloud security, Cortex for security operations, and CyberArk for identity security, plus Unit 42 threat research and response services.
Why did Palo Alto Networks buy CyberArk?
To add identity security as its fourth platform, arguing that securing human, machine, and AI-agent identities is becoming the central problem of enterprise security. The ~$25 billion deal closed February 11, 2026.
How many employees does Palo Alto Networks have?
Approximately 19,000 globally including CyberArk's roughly 3,000, with major engineering hubs in California, Israel, and India.
Palo Alto Networks publishes ESG reporting covering emissions reduction targets, supply chain standards for its hardware manufacturing, and workforce metrics. Its material ethics footprint is different from consumer companies: as a security vendor its product decisions, such as vulnerability disclosure practices and government sales policies, are its most significant ethical surface.
The company's Cortex research arm, Unit 42, publishes threat intelligence used across the industry, and the company participates in coordinated vulnerability disclosure standards. Its hardware supply chain is contract-manufactured primarily in Asia under supplier codes of conduct.
Palo Alto Networks has been named a leader in the Gartner Magic Quadrant for network firewalls for well over a decade consecutively and holds leader positions in analyst evaluations of SASE, cloud workload protection, XDR, and SIEM. It appears regularly on the Fortune Future 50 and Forbes' lists of top employers in technology.
The company has faced the normal legal and competitive friction of a dominant vendor: patent litigation with rivals including a high-profile dispute with Centripetal Networks that produced a large initial verdict against it before appeal, and periodic competitive complaints about bundling practices as platformization tightens its grip on customer budgets.
Its most debated industry issue is platformization itself: critics argue the strategy exploits customer fatigue to lock in a single vendor, while the company counters that fragmented security is the actual risk. The 2024 outage of a CrowdStrike update, which took down millions of Windows systems industry-wide, benefited Palo Alto competitively but also renewed regulatory attention on security software monocultures.
No major breach, recall, or regulatory sanction attaches to the company's products themselves, and its vulnerability handling has largely avoided the criticisms leveled at some security peers.
