TLS 1.3 is enforced on all endpoints; TLS 1.2 is the absolute minimum and only permitted for clients that cannot negotiate 1.3. We use ECDHE key exchange with forward secrecy and modern AEAD cipher suites only. Internal service-to-service traffic uses mTLS with short-lived certificates issued by an internal CA.
