Zscaler is a publicly traded cloud security company (NASDAQ: ZS) that pioneered the secure access service edge (SASE) architecture. The company’s Zero Trust Exchange platform processes over 400 billion transactions daily, securing users, workloads, and devices.
Zero Trust Exchange Platform
Zscaler’s cloud-native platform replaces legacy network security appliances with a comprehensive set of services.
Zscaler Internet Access (ZIA) provides secure internet and SaaS access through a Secure Web Gateway (SWG) with SSL inspection, Cloud Access Security Broker (CASB), Data Loss Prevention (DLP), cloud firewall with IPS, and sandboxing for malware analysis.
Zscaler Private Access (ZPA) delivers zero trust network access for private applications. It handles application segmentation without network segmentation, provides user-to-application connectivity rather than network-to-network, eliminates VPN attack surface, and offers browser isolation for unmanaged devices.
Zscaler Digital Experience (ZDX) gives organizations end-to-end visibility into user experience with application performance monitoring, network path analysis, device health metrics, and troubleshooting workflows.
Zscaler for Workloads handles cloud workload protection including workload-to-internet security, workload-to-workload segmentation, cloud connector deployment, and multi-cloud support across AWS, Azure, and GCP.
Zero Trust Architecture
Zscaler’s architecture embodies core zero trust principles. Every request is authenticated and authorized with context-aware access decisions based on user, device, location, and content. The platform uses continuous trust evaluation rather than one-time authentication.
Applications remain invisible to the internet with no inbound connections to corporate networks. The direct-to-cloud architecture eliminates backhauling. Full SSL/TLS inspection covers all traffic with inline threat prevention and deception technology integration.
Financials
Zscaler reported FY2025 revenue of $2.67 billion, representing 23% year-over-year growth. ARR exceeded $3.2 billion, and the company now has 698 customers with over $1 million in ARR, a 20% increase year-over-year. More than 45% of Fortune 500 companies and approximately 40% of Global 2000 companies use Zscaler.
