Zscaler (NASDAQ:ZS) is a cloud security company that delivers a cloud-native platform to protect users, applications and data as organizations move away from traditional, network-centric security architectures. The company focuses on a zero trust approach that assumes no implicit trust for users or devices, providing secure access to the internet, SaaS applications and private applications regardless of where users are located. Zscaler positions its services as an alternative to legacy appliances and site-centric VPNs, aiming to simplify security while enabling modern, distributed workforces.
Key offerings are built around the Zscaler Zero Trust Exchange, a multi-tenant cloud platform that enforces security and access policies in-line. Its principal products include Zscaler Internet Access (ZIA) for secure internet and SaaS access, Zscaler Private Access (ZPA) for secure, brokered access to internal applications without a traditional VPN, and Zscaler Digital Experience (ZDX) which monitors and helps troubleshoot end-user performance. The platform incorporates capabilities typically used by enterprises—secure web gateway (SWG), cloud access security broker (CASB) functions, data loss prevention (DLP), next-generation firewalling, SSL inspection, sandboxing and threat intelligence—to deliver a consolidated security stack delivered from the cloud.
Headquartered in San Jose, California, Zscaler serves enterprise and public sector customers around the world through a network of cloud enforcement points and regional operations. The company was founded and is led by Jay Chaudhry, who has served as chairman and chief executive officer, and it completed a public offering in 2018. Zscaler’s offerings are commonly adopted by organizations undergoing digital transformation, seeking to secure cloud adoption, remote work and hybrid IT environments while reducing dependency on on-premises security appliances.
