Bulk expiry monitoring vs deep TLS configuration analysis
| Feature | SSL Labs | ConfigClarity SSL |
|---|---|---|
| TLS grade (A/B/C/F) | ✓ Detailed | ✗ Not the focus |
| Cipher suite analysis | ✓ Comprehensive | ✗ No |
| Certificate chain validation | ✓ Deep | ✓ Via crt.sh |
| Multiple domains at once | ✗ One at a time | ✓ Unlimited |
| Expiry days remaining | ✓ Yes | ✓ Color coded |
| CDN certificate detection | ✓ Yes | ✓ Orange flag |
| 200-day validity flag | ✗ No | ✓ New CA/B rules |
| Export PNG report | ✗ No | ✓ Yes |
| Security headers check | ✗ No | ✓ Per domain |
| Runs in browser | ✗ Server-side | ✓ Client-side only |
| Speed (per domain) | 60–120 seconds | 2–5 seconds |
| Rate limits | Strict | None |
SSL Labs is the gold standard for deep TLS security analysis. Use it when you need to verify cipher suites, TLS version support, HSTS configuration, or certificate chain completeness. It's the right tool for a security audit of a specific domain.
ConfigClarity is for bulk expiry monitoring. Paste 20 domains and see which ones expire in the next 30 days. It's fast (no server-side scanning), supports bulk checking, and gives you a PNG export for team reports. Use it weekly to catch expiring certificates before they cause downtime.
Paste any number of domains and see expiry dates, issuer, CDN detection, and 200-day validity flags — no rate limits, no signup.
Open SSL Checker →No — that requires a full TLS handshake from a server, which a browser-only tool can't do without a backend. For cipher suite analysis, use SSL Labs. ConfigClarity focuses on expiry monitoring and certificate metadata from Certificate Transparency logs.
Apple and the CA/Browser Forum have been reducing maximum certificate validity. The current trajectory points to 200-day maximum (and eventually 47-day) certificates. ConfigClarity flags certs with total validity over 200 days — issued under old rules — as needing replacement at their next renewal.
