Run a full SSL Labs scan and resolve all warnings

30-60 min Impact: high Effort: medium ✓ Manual completion

A full SSL Labs scan checks far more than just whether HTTPS works — protocol versions, cipher strength, certificate chain completeness, and known vulnerabilities — giving a comprehensive letter grade for your actual HTTPS configuration quality.

A site can have HTTPS working with no visible browser warnings while still carrying a genuinely weak configuration underneath — this is the tool that surfaces exactly what a browser padlock alone does not tell you.

The full picture

A full SSL Labs scan provides genuinely comprehensive, third-party evaluation of your complete TLS/SSL configuration, checking dozens of specific technical factors beyond what any single individual check throughout this broader security work addresses in isolation — this represents a consolidated, expert-level assessment of your encryption implementation's overall quality.

This tool specifically evaluates factors including your certificate chain validity, supported protocol versions, cipher suite strength and ordering, and numerous other technical details that collectively determine your actual encryption implementation's real-world security quality — issues in any of these specific dimensions can undermine your overall HTTPS security even when more basic checks appear satisfied.

The genuine value of this comprehensive scan comes from its independent, expert-calibrated evaluation criteria — rather than relying solely on your own verification of individual factors, this tool applies current, security-community-vetted standards to comprehensively assess your configuration against genuine best practices that continue evolving as the security landscape changes.

Working through and resolving whatever specific warnings this scan identifies for your particular configuration represents genuine, expert-guided security hardening — this tool's detailed technical findings provide specific, actionable guidance for addressing whatever gaps exist in your current implementation, going meaningfully deeper than what manual review alone would typically catch.

How to do it

1

Run the scan

Enter your domain at SSL Labs and let the full test complete, it checks many configuration angles at once.
2

Review every warning, not just the final grade

The overall letter grade is useful, but the specific flagged issues are what actually need fixing.
3

Address issues in order of severity

Certificate chain problems and weak protocols typically matter more than minor cipher suite ordering issues.
4

Re-scan until clean

Keep iterating until the scan shows no unresolved warnings.

Common mistakes

This overlaps with several other checks (TLS versions, certificate validity) — running this scan can efficiently surface multiple related issues at once instead of checking each individually.
