Zscaler, Inc. is a cloud security company that provides a range of services designed to protect enterprises as they transition from traditional data centers to cloud-based architectures. Founded in 2007 and headquartered in San Jose, California, Zscaler pioneered a security model known as Zero Trust Exchange, which assumes no user or device should be trusted by default—even if they are connected to a corporate network. The company offers its platform via a global, multi-tenant cloud infrastructure that delivers security as a service rather than relying on legacy on-premises appliances.
The company’s flagship offerings include Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA). ZIA secures web and internet traffic by enforcing policy-based access controls, data loss prevention, and threat protection at the network edge. ZPA enables secure remote access to internal applications without exposing them to the public internet, leveraging identity-based segmentation to reduce attack surfaces. Zscaler Digital Experience (ZDX) complements these products by providing insights into user experience and application performance across the digital supply chain.
Zscaler serves a broad array of industries—such as financial services, healthcare, manufacturing, and retail—helping organizations in North America, Europe, Asia-Pacific, and beyond to modernize their security architectures. By replacing traditional security stacks with its cloud-native platform, the company aims to simplify management, improve performance, and enhance visibility across distributed workforces. Customers range from small businesses to global enterprises seeking to secure remote users, branch offices, and cloud workloads.
Under the leadership of founder, chairman, and CEO Jay Chaudhry, Zscaler went public on the Nasdaq stock exchange in March 2018. The executive team blends expertise in cybersecurity, cloud networking, and enterprise software. With ongoing investments in threat research and platform innovation, Zscaler positions itself at the forefront of the Secure Access Service Edge (SASE) market, driving adoption of zero trust principles and helping organizations navigate the evolving security landscape.
