Key competitors based on market analysis and public filings.
Zscaler provides a cloud-native zero-trust security platform that replaces traditional network security appliances (firewalls, VPNs, proxies). Its platform inspects all internet and private application traffic inline, applying security policies regardless of where users, workloads, or devices are located.
Zscaler generates revenue through subscription fees for its cloud security platform. Customers pay based on the number of users and the product bundles they deploy (ZIA, ZPA, ZDX, Data Protection). The company uses a land-and-expand model, with most customers starting with one product and expanding to additional modules over time.
Zero trust is a security framework that assumes no user, device, or network should be inherently trusted. Instead of perimeter-based security, zero trust verifies every access request in real time. It matters because the shift to remote work, cloud applications, and distributed architectures has made traditional perimeter defenses obsolete.
Zscaler's primary competitors include Palo Alto Networks (Prisma SASE), Cloudflare (Cloudflare One), Netskope (Security Service Edge), and Fortinet (FortiSASE). Zscaler differentiates through its purpose-built cloud architecture, processing scale (400B+ daily transactions), and decade-long head start in cloud-native security.
