Comprehensive SSL Monitoring and Alert Workflow

This n8n workflow provides an advanced, cost-effective SSL certificate monitoring solution designed for DevOps, IT admins, and security professionals. It automates daily SSL health checks across multiple domains by combining external APIs and custom scripts for thorough analysis. The workflow starts with a scheduled trigger to run every morning, fetching website URLs from a Notion database. For each domain, it performs an SSL check via the ssl-checker.io API and a custom SSL health assessment script via SSH. The results are then processed to evaluate certificate expiration, security vulnerabilities, protocol support, and compliance. Critical issues trigger detailed Discord alerts with formatted information, including SSL grades, vulnerabilities, and recommendations. The setup allows for proactive management of SSL security, helping organizations maintain compliant, secure websites without expensive monitoring tools.
