Zero Trust for SaaS: Deploying mTLS on custom hostnames

What this post added

This post introduces the ability for SaaS providers to enable mutual TLS (mTLS) authentication on their customers' domains through Cloudflare Access. This extends the zero-trust security model to scenarios where SaaS providers manage origins for domains they do not own, allowing them to enforce device-level authentication for sensitive API endpoints and provide per-customer isolation.
