Zscaler pioneered cloud-delivered security services and has become the definitive leader in Secure Service Edge (SSE) and Secure Access Service Edge (SASE) solutions. Founded in 2007 and headquartered in San Jose, California, Zscaler operates one of the world's largest security clouds, processing over 500 billion transactions daily across 150+ data centers globally. The company's Zero Trust Exchange architecture fundamentally reimagines enterprise security for the cloud and mobile era.
Rather than routing traffic through centralized data centers, Zscaler's platform connects users directly to applications through the nearest cloud security node, inspecting all traffic in-line. This architecture eliminates traditional VPNs and reduces attack surfaces by making applications invisible to the internet. The platform includes Internet Access (secure web gateway and firewall), Private Access (zero trust network access), and Digital Experience monitoring. Zscaler's AI-powered threat detection analyzes billions of transactions to identify emerging threats.
The company has achieved remarkable growth serving Fortune 500 companies, government agencies, and organizations transforming from castle-and-moat security to cloud-centric architectures. Zscaler regularly receives top recognition in Gartner Magic Quadrants for SSE and ZTNA. Their platform scales seamlessly from hundreds to hundreds of thousands of users. The company has executed strategic acquisitions including Trustdome (browser isolation) and Airgap Networks (zero trust) to expand capabilities.
For enterprises executing cloud transformation and zero trust strategies, Zscaler delivers market-leading technology with proven scale. Their pure cloud architecture and strong financial performance indicate long-term viability. Best suited for large, distributed organizations moving applications to the cloud and supporting remote workforces globally.
