AWS Certificate Manager supports ACME for public certificates
AWS Certificate Manager (ACM) now offers a managed ACME server endpoint for provisioning public TLS certificates with a 45-day validity. This feature automates certificate issuance and renewal using standard ACMEv2 clients, addressing the increasing difficulty of manual certificate management due to shorter mandated lifetimes. It allows PKI administrators to enforce governance and delegate certificate requests, with all activity logged in ACM and CloudTrail.

Features (2) ›
- Managed ACME server endpoint for public TLS certificates
ACM now provides a fully managed ACME server endpoint that issues public TLS certificates with a 45-day validity from Amazon Trust Services. This supports any ACMEv2-compatible client, such as Certbot and cert-manager.
- Centralized governance and delegation for PKI administrators
PKI administrators can create managed ACME endpoints with centralized controls to define domain scopes, enforce wildcard usage policies, and delegate certificate requests to application teams without sharing DNS credentials.
Enhancements (2) ›
- Automated certificate issuance and renewal
The ACME support offers a standards-based approach for developers to fully automate the issuance and renewal of public certificates, which is crucial given upcoming CA/Browser Forum mandates for shorter certificate lifetimes.
- Auditability and monitoring of certificate activity
All ACME-related activity is logged in the ACM console, with AWS CloudTrail logging and Amazon CloudWatch metrics available for enhanced auditability.
