I’m sharing my latest workflow for monitoring and validating SSL.
<h3>How it works</h3>
<ol>
<li>Daily Trigger runs the workflow every morning for proactive monitoring.</li>
<li>URL Collection fetches the list of website URLs to monitor from your data source.</li>
<li>Dual SSL Analysis:
<ul>
<li>Bubobot SSL Scanner — Our free <a href="https://github.com/Bubobot-Team/sysadmin-toolkit/blob/main/scripts/ssl/ssl-health-assessment.js" target="_blank" rel="noopener nofollow">SSL health assessment script</a> tool</li>
<li><a href="http://SSL-Checker.io" target="_blank" rel="noopener nofollow">SSL-Checker.io</a> API — External verification for cross-validation</li>
</ul>
</li>
<li>Comprehensive Health Check:
<ul>
<li>Certificate expiration monitoring (customizable threshold)</li>
<li>SSL configuration security assessment</li>
<li>Protocol support analysis (TLS 1.3, 1.2, deprecated protocols)</li>
<li>Cipher suite strength evaluation</li>
<li>Vulnerability scanning (POODLE, BEAST, etc.)</li>
<li>Compliance checking (PCI DSS, NIST, FIPS)</li>
</ul>
</li>
</ol>

<h3>How does it scan and validate your cert?</h3>
<ul>
<li>2 steps verification: Cross-checks results between internal scanner and external API</li>
<li>SSL grading: A+ to F rating system with detailed analysis</li>
<li>Security assessment: Vulnerability detection and compliance checking</li>
<li>Discord integration: Rich embed notifications with color-coded alerts</li>
</ul>
