Cloudflare Zero Trust vs Zscaler

Cloudflare Zero Trust offers the most developer-friendly and cost-effective path to zero trust security, backed by the world's largest Anycast network. Zscaler provides a more mature and feature-complete SASE platform with deeper inspection capabilities and stronger enterprise support, but at significantly higher cost. Cloudflare is closing the feature gap rapidly and is particularly strong for organizations that value API-first configuration and transparent pricing.

The Bottom Line

Choose Cloudflare Zero Trust if you want enterprise-grade zero trust security with transparent pricing, a free tier for getting started, and developer-friendly Terraform/API configuration.
