Zscaler (NASDAQ:ZS) (NASDAQ: ZS) is a leading provider of cloud-native cybersecurity solutions designed to securely connect users, applications and devices in a rapidly evolving digital landscape. Founded in 2008 by industry veteran Jay Chaudhry and Kailash Kailash, the company pioneered the Secure Access Service Edge (SASE) framework, delivering scalable and globally distributed security controls without reliance on legacy perimeter appliances. Headquartered in San Jose, California, Zscaler operates a multi-tenant cloud platform that inspects all traffic—SSL encrypted or not—providing comprehensive threat protection and data loss prevention for enterprises of all sizes.
The core of Zscaler’s offering is its Zero Trust Exchange, a cloud-native service that enforces least-privilege access to applications based on user identity, device posture and real-time risk assessment. Key products include Zscaler Internet Access (ZIA), which functions as a secure web gateway, firewall, sandbox and cloud access security broker (CASB), and Zscaler Private Access (ZPA), which enables seamless, direct connections to internal applications without exposing networks to the public internet. These services are delivered from over 150 data centers worldwide, ensuring low-latency performance and continuous policy enforcement regardless of user location.
Over time, Zscaler has expanded its global footprint to serve customers across the Americas, Europe, Middle East, Africa and Asia–Pacific regions. Its platform supports a diverse range of industries, including financial services, healthcare, manufacturing and retail, helping organizations migrate from traditional VPNs and on-premises security appliances to a modern, cloud-delivered approach. Strategic partnerships with leading cloud providers and managed service vendors further extend Zscaler’s ability to integrate security into multi-cloud environments and digital transformation initiatives.
Under the leadership of Jay Chaudhry as Chairman and CEO, along with an experienced executive team, Zscaler has continued to innovate through research and development, expanding its security stack to address emerging threats such as ransomware, phishing and advanced persistent threats. The company’s commitment to zero trust principles and its agile, subscription-based delivery model have positioned it as a key enabler of secure cloud adoption and remote work strategies for enterprises worldwide.
