RDS PostgreSQL 18 adds post-quantum TLS key exchange
AWS puts hybrid ML-KEM on a customer-provisioned database (not a service endpoint) which means the defense supply chain can configure it directly rather than wait for transparent rollout.
Amazon RDS for PostgreSQL versions 18 and higher now support modifying the ssl_groups parameter to select post-quantum TLS cryptographic groups, including hybrid ML-KEM key exchange. This is the first PQ deployment on a database instance customers provision and configure themselves, as opposed to the transparent server-side rollouts AWS has done on KMS, ACM, and Secrets Manager endpoints. Defense contractors running RDS PostgreSQL 18 can align with NIST's PQC transition by updating a parameter in the console or CLI, no stack migration required.
