The world's largest security cloud — ZTNA, SASE, and data protection at scale
Zscaler built the internet as the network before that idea was fashionable. The Zscaler Zero Trust Exchange processes over 400 billion transactions per day through 150+ global data centers — enforcing zero-trust access policies for every user, every application, and every device without VPN, without firewall, and without hairpinning traffic through your data center. If your organization is serious about zero trust and SASE, Zscaler is the platform that Gartner, Forrester, and the NSA all point to first.
Zscaler is the pioneer of the Security Service Edge (SSE) and SASE market. The Zscaler Zero Trust Exchange is a cloud-native platform that replaces traditional network security infrastructure — VPNs, on-premises firewalls, and proxies — with a globally distributed cloud that enforces security policy at the point of access. ZIA (Zscaler Internet Access) secures internet-bound traffic. ZPA (Zscaler Private Access) provides zero-trust access to internal applications without VPN. ZDPE extends these principles to devices and workloads. Together, they represent the most comprehensive SASE architecture available from a single vendor.
Deployment model: 100% cloud-delivered (SaaS); no hardware required. Pricing model: Annual subscription per user. Typical price range: $150–$350/user/year (bundle dependent). Pricing is negotiable at volume — Compare Select benchmarks quotes against real transacted deals before you sign.
Cloud-native secure web gateway, CASB, DLP, and sandboxing. All internet-bound traffic is inspected inline — including SSL/TLS — with zero latency impact.
Zero-trust network access that connects users to specific applications — not the network. VPN replaced entirely: no implicit trust, no lateral movement risk.
ML models trained on 400B+ daily transactions identify novel phishing pages, zero-day malware, and C2 communications that signature-based tools miss entirely.
Extends zero trust to server-to-server and cloud workload communications — microsegmentation without firewall rules.
| Alternative | How it compares |
|---|---|
| Palo Alto Prisma SASE | Palo Alto offers strong NGFW integration with their SASE stack. Zscaler's cloud-native architecture delivers better global performance for distributed workforces. |
| Cloudflare One | Cloudflare One is strong for developer-centric and edge-computing organizations. Zscaler has deeper enterprise features including DLP, CASB, and compliance reporting. |
| CrowdStrike | CrowdStrike focuses on endpoint and identity security. Zscaler focuses on network and application access. Best-in-class deployments often include both. |
Yes — ZPA provides per-application access without network-level connectivity. Users access specific apps through the Zscaler cloud, with no ability to traverse the network laterally. The main consideration is application discovery (documenting all private apps that users need) before going live. Compare Select manages the application discovery phase.
