Comprehensive SSL Certificate Monitoring with Discord & Notion

This advanced n8n workflow automates comprehensive SSL certificate monitoring for multiple domains, triggered daily to ensure proactive security oversight. It fetches URLs from a data source, then performs dual analysis: an internal free SSL assessment script from sysadmin-toolkit and cross-verification via the SSL-Checker.io API. This setup detects certificate expirations (customizable threshold, default 30 days), evaluates SSL configurations, protocol support (TLS 1.3/1.2, deprecated ones), cipher suite strength, vulnerabilities like POODLE/BEAST, and compliance with PCI DSS, NIST, and FIPS standards.

Key features include SSL Labs-style grading (A+ to F) for intuitive health scores, smart alerting for issues like expiring certs, weak configs, or low grades, and seamless integrations with Discord for real-time notifications and Notion for logging detailed reports. Dual verification minimizes false positives, providing reliable insights without costly third-party services.

Ideal for DevOps engineers, IT admins, and security professionals managing web infrastructure. It saves hours of manual checks, prevents downtime from expired certs, enhances compliance, and scales effortlessly for portfolios of sites—perfect for agencies, enterprises, or SaaS providers prioritizing cybersecurity.
