San Jose, California
Zscaler, Inc. is a leading global cloud security company headquartered in San Jose, California. Founded in 2007 by Jay Chaudhry and K. Kailash, the company pioneered a fundamental shift in cybersecurity by replacing traditional, appliance-based network security and virtual private network (VPN) architectures with a cloud-native platform built on zero trust principles. Initially incorporated as SafeChannel, Inc., the company rebranded to Zscaler in August 2008 and launched its initial cybersecurity platform the same year. After several successful funding rounds, Zscaler went public on the Nasdaq exchange in March 2018 under the ticker symbol ZS and was subsequently added to the Nasdaq-100 index in December 2021. The core of Zscaler’s business revolves around its proprietary Zero Trust Exchange platform, which acts as an inline security cloud that secures users, workloads, branches, and devices. Operating within the Security Service Edge (SSE) and Secure Access Service Edge (SASE) markets, the company’s architecture ensures that information exchange is secure and seamless, regardless of location. This approach is highly effective in modern decentralized work environments where enterprise applications have moved to software-as-a-service (SaaS) and public clouds. Zscaler’s primary offerings include Zscaler Internet Access (ZIA), which provides secure access to external applications and internet destinations, and Zscaler Private Access (ZPA), which delivers fast and secure direct access to internally hosted private applications. Additionally, the company provides Zscaler Digital Experience (ZDX) to monitor user experience across business networks, alongside robust data protection and workload segmentation tools designed to stop lateral threat movement within cloud infrastructures. Zscaler operates on a subscription-based SaaS model, catering to a diverse range of enterprise and public sector customers globally across the Americas, Europe, the Middle East, Africa, and the Asia-Pacific region. Its clientele spans multiple industries, including banking, healthcare, manufacturing, telecommunications, and government agencies. As of 2026, Zscaler secures over 500 billion daily transactions and services more than 9,400 customers, including approximately 40% of the Forbes Global 2000. To expand its technological capabilities, Zscaler has pursued a strategy of targeted acquisitions, integrating companies like TrustPath, Cloudneeti, Edgewise Networks, Smokescreen Technologies, ShiftRight, Canonic, Avalor, Airgap Networks, Red Canary, and SquareX. Financed by solid institutional backing, Zscaler has scaled its operations to employ nearly 8,000 personnel. For the fiscal year 2024, the company reported total revenue of USD 2.17 billion, reflecting its substantial market presence and high enterprise penetration amid the ongoing convergence of networking and digital security.
