GKE Gateway now supports backend mutual TLS (mTLS)
UpdateUnverifiedAdded Sep 24, 2026
GKE Gateway now supports backend mutual TLS (mTLS). In addition to backend authenticated TLS, backend mTLS allows the GKE Gateway load balancer to authenticate its identity to backend Pods by presenting a client certificate. GKE Gateway configures backend mTLS using the standard Gateway API spec.tls.backend.clientCertificateRef field.
