How Zscaler makes money

Zscaler sells its cloud security platform to enterprises and public-sector organizations, which pay for access to its products and add-on modules such as data security, AI security, and security operations tools.

What Zscaler does

Zscaler, Inc. is a San Jose-based cloud security company founded in 2007 (originally SafeChannel). Its core idea is "zero trust": rather than trusting anyone inside a corporate network, it verifies every connection through its cloud platform. Flagship offerings include Zscaler Internet Access for safe web and cloud use, Zscaler Private Access for reaching internal apps without a traditional VPN, and Zero Trust SASE, which connects workforces, AI agents, workloads, and IoT/OT devices to cloud apps and AI services. Around that core, Zscaler has added data security (AI-powered classification, DLP, SaaS security, posture management), Security for AI, digital experience monitoring, a zero trust browser for third parties, and security operations tools covering exposure management, deception, managed detection and response, and threat hunting. Its customers span industries including financial services, healthcare, manufacturing, public sector, telecom, and retail.
