Tutorial

Secure Machine-to-Machine Access with mTLS and Pomerium

Run a GitHub Actions-compatible continuous integration (CI) job on a private runner and protect its internal API call with mutual TLS (mTLS) and Pomerium. Build separate server and client trust chains, authorize one machine certificate by fingerprint, then revoke, restore, and rotate its credentials through live policy changes.
