Unified application services for all origins

Apply the same security, performance, and programmability stack (WAF, bot management, rate limiting, caching, edge compute, transform rules) to origins regardless of whether they are reachable over the public Internet or only through private network paths.

Shape

1. The proxy platform maintains a complete L7 application-services pipeline that runs on every request.
2. After pipeline processing, the proxy consults origin metadata to determine how to reach the origin.
3. If the origin is public, the proxy connects directly over the public Internet.
4. If the origin is private, the proxy hands the connection to a private networking layer.
5. The application-services pipeline is identical in both cases — no feature degradation for private origins.

Why it matters

Historically, private applications got either no CDN/WAF services (behind a VPN, invisible to the edge), or required architectural compromises (public load balancers, connector software, separate product stacks). This pattern collapses the "public vs. private" origin distinction into a routing decision at the proxy layer's final hop, eliminating the forced trade-off between security-as-a-service and network isolation.
