Zscaler

Zscaler is a global leader in cloud security, pioneering the Zero Trust security model since its founding in 2007. The company operates the world's largest security cloud, the Zscaler Zero Trust Exchange, which processes over 500 billion transactions daily across more than 160 data centers worldwide. This cloud-native platform has fundamentally transformed how organizations secure their users, applications, and data by eliminating the traditional network perimeter and replacing legacy VPNs and firewalls with intelligent, policy-based access controls.

Founded by Jay Chaudhry, a serial entrepreneur who previously built and sold four security companies, Zscaler went public in March 2018 and has consistently demonstrated strong growth and innovation. As of fiscal 2025 (ending July 31, 2025), Zscaler surpassed $3 billion in annual recurring revenue, processing nearly 60 times more transactions per day than Google searches. The company serves thousands of enterprise customers including major Fortune 500 companies like T-Mobile, helping them modernize their security infrastructure and embrace cloud-first architectures.

Zscaler's comprehensive platform includes flagship products such as Zscaler Internet Access (ZIA) for secure internet gateway services, Zscaler Private Access (ZPA) for zero trust network access, and Zscaler Digital Experience (ZDX) for application performance monitoring. With a strong commitment to AI-powered security and continuous innovation, including recent acquisitions like Red Canary for $675 million, Zscaler is leading the industry's transformation toward Zero Trust Everywhere, fundamentally changing how organizations approach cybersecurity in an increasingly distributed and cloud-centric world.
