Zscaler Targets $10 Billion in ARR

CEO Jay Chaudhry said the rise of agentic AI could become one of the biggest opportunities in Zscaler's history.

He said the company's Zero Trust platform is designed to defend against AI-driven threats, protect sensitive data and help companies deploy AI more securely.

The platform can also reduce attack surfaces and limit the ability of threats to move across corporate networks.

Chaudhry said Zscaler's customer growth flywheel and multiple growth engines could help the company capitalize on AI tailwinds and move toward its $10 billion ARR target.
