Zscaler, Inc.: CEO History

Zscaler's platform processes over 500 billion transactions daily, extracting 300 trillion signals and blocking 100 million threats. Those numbers represent the scale of the security problem that the traditional perimeter firewall model was never designed to solve — and they explain why $2.67 billion in annual recurring revenue at 23 percent growth has a $3.015 billion ARR base heading into fiscal 2026. The company sells architectural transformation, not security software features. Every enterprise network still built around a central datacenter perimeter, with VPNs extending that perimeter to remote workers, becomes a security liability as users access cloud applications from everywhere. Zscaler's Zero Trust Exchange routes all traffic through its own cloud, inspecting it inline and applying policy — eliminating the perimeter rather than defending it. Founded in 2007 by Jay Chaudhry and Kailash Kailash in San Jose, California, the company went public in March 2018. Revenue has grown from $1.09 billion in fiscal 2022 to $2.67 billion in fiscal 2025, nearly tripling in three years. Deferred revenue of $2.47 billion as of fiscal 2025 provides forward visibility into contracts already signed but not yet recognized. Chaudhry built and sold four companies before founding Zscaler. His background: born in a Himalayan village without electricity or running water until the 10th grade, engineering education in India, immigration to the United States, and a career building security companies that he sold to Cisco, McAfee, and others before retaining the equity upside himself with Zscaler.
