Automated AWS ACM SSL/TLS Certificate Expiry Reports for Slack & Email

This n8n workflow automates the monitoring and reporting of SSL/TLS certificates in AWS Certificate Manager (ACM). Triggered weekly, it fetches all certificates, parses key details like expiry dates, status, and SANs, then leverages OpenAI agents to generate polished Markdown and HTML reports. The Markdown is converted to PDF for Slack delivery, while HTML is sent via email, providing teams with actionable insights on renewal needs.

Benefits include reduced risk of service disruptions from expired certs, streamlined compliance audits, and time savings for DevOps and cloud admins. No manual checks required—AI ensures reports are concise, visually appealing, and tailored for quick review.

Ideal for organizations managing AWS infrastructure, especially in regulated industries like finance or healthcare. Use cases: proactive certificate renewals, executive summaries, team notifications, and integrating into broader security workflows.
