Zscaler review and pricing

SASE category leader with proven hyperscale and FedRAMP High depth.

By Zscaler, Inc. · Founded 2007 · San Jose, CA · public

Zscaler is the SASE / SSE category leader, public on NASDAQ:ZS since 2018, founded 2007 by Jay Chaudhry (still CEO). The product portfolio (Zscaler Internet Access / ZIA, Zscaler Private Access / ZPA, Zscaler Digital Experience / ZDX) covers the full SSE stack: secure web gateway, ZTNA, CASB, DLP, and digital-experience monitoring. Best fit for global enterprises (5,000+ employees) requiring proven hyperscale, FedRAMP High authorization, and deep direct-to-cloud architecture. The company reported ~$2.2B revenue FY24 with strong growth, and maintains a 150+ data-center global footprint. Trade-offs: pricing has escalated meaningfully at renewal (10-20% increases consistently reported), enterprise-only sales motion makes mid-market procurement painful, and the April 2024 alleged-stolen-credentials investigation (Zscaler concluded no breach occurred but the disclosure cycle dented trust briefly) is still cited by some buyers. The product is also feature-dense to the point of complexity; junior teams routinely underuse what they paid for.
