Jay Chaudhry, K. Kailash · Founded 2007 · San Jose, California, United States

Zscaler was founded by Jay Chaudhry, K. Kailash in 2007 in San Jose, California, United States. The company is currently led by Jay Chaudhry.

Founding Story

Jay Chaudhry

Co-founder 2007

Background

Jay Chaudhry was born August 26, 1958, in Panoh, a small village in Punjab (now Himachal Pradesh), India, and earned a bachelor's degree in electronics engineering from IIT BHU before three master's degrees from the University of Cincinnati. He built a career of founding and exiting security startups: SecureIT (founded 1996, acquired by VeriSign in 1998), CoreHarbor (acquired by USi/AT&T), CipherTrust (founded 2000, merged with Secure Computing), and AirDefense (acquired by Motorola), before founding Zscaler with K. Kailash in 2007. Chaudhry has remained Zscaler's CEO and chairman through its 2018 IPO and subsequent growth to more than $3 billion in annual recurring revenue. Chaudhrys pattern of founding, scaling, and exiting multiple security companies before Zscaler gave him a rare vantage point on which security-market problems remained unsolved by existing vendors, directly informing Zscalers original zero-trust cloud architecture bet. Chaudhry family, including his wife Jyoti who also holds significant Zscaler leadership responsibilities, represents one of the more prominent husband-and-wife executive teams in enterprise technology.

K. Kailash

Co-founder 2007

Background

K. Kailash co-founded Zscaler with Jay Chaudhry in 2007, helping build the cloud-native security architecture that became the technical foundation of the company's Zero Trust Exchange platform. Kailash has maintained a lower public profile than Chaudhry throughout Zscaler's growth, focusing on engineering leadership rather than the external-facing CEO and evangelist role Chaudhry has taken on within the cybersecurity industry. His continued technical leadership role within Zscaler engineering organization, even as the company has scaled to thousands of employees, reflects a deliberate choice to remain close to product architecture rather than transition into purely executive management.

Co-founder, Chairman and CEO

2007 – Present

Under Chaudhry, Zscaler crossed $3 billion in annual recurring revenue in fiscal 2025 and guided to about 24% ARR growth for fiscal 2026, with AI-security products alone approaching $400 million of that total. Chaudhrys continued day-to-day involvement as both chairman and CEO, unusual for a company of Zscalers scale nearly two decades after founding, reflects his particularly hands-on leadership style relative to founders who typically transition to board-only roles much earlier. Chaudhry has stated publicly that he views Zscaler as his final company, distinguishing it from his earlier pattern of founding and exiting multiple security startups in succession.
