Automating certificate management is crucial for organizations using AWS Private CA, especially to handle custom validity periods and monitor expiration dates. Utilizing AWS services like EventBridge, Lambda, and SNS, a scalable solution is proposed to generate audit reports that track certificate statuses and notify stakeholders of upcoming expirations. This approach enhances operational security and ensures timely compliance with certificate management needs.

The CA/Browser Forum has voted to reduce the maximum lifetime of TLS certificates to 47 days by March 15, 2029, in a series of scheduled reductions. This change aims to enhance security through frequent revalidation of certificate information and promote automation in certificate lifecycle management. As shorter lifetimes become mandatory, the adoption of automated solutions is expected to increase significantly among users.
