AWS Secrets Manager vs. Certificate Manager for Certificates

AWS Certificate Manager (ACM) is designed to issue, validate, renew, and deploy TLS certificates for supported AWS services, while AWS Secrets Manager can securely store certificate files and private keys but treats them as ordinary text without certificate-aware expiry monitoring or renewal. For TLS terminated by services such as Elastic Load Balancing, CloudFront, API Gateway, and others integrated with ACM, ACM is presented as the preferred option because it supports automatic deployment and renewal for ACM-issued certificates. For self-managed workloads outside those integrations, ACM introduced exportable certificates in 2025 and an ACME service that lets standard clients obtain Amazon-issued certificates directly, although exportable certificates require redeployment after renewal and ACME certificates cannot be used by integrated AWS services. Secrets Manager remains useful when certificates must be delivered to systems that cannot access ACM directly, but users must build processes to detect expiration, rotate files, and reload affected services. The discussion also notes that shorter public certificate lifetimes increase the need for automated lifecycle management and presents Infisical Certificate Management as a cross-environment alternative for discovering, issuing, renewing, and synchronizing certificates across AWS, on-premises systems, network hardware, and other clouds.
