Jay Chaudhry and K. Kailash founded Zscaler in 2007 to rebuild corporate security as a cloud service rather than a stack of on-premise appliances. The San Jose company routes employee web and application traffic through its Zero Trust Exchange, brokering access per-session instead of trusting the network perimeter. Core products split into ZIA for internet filtering, ZPA for private app access, and ZDX for digital experience monitoring. Shares debuted on NASDAQ in March 2018 at $16, and annual recurring revenue has since crossed $2 billion as enterprises retire legacy VPNs.
