Developer-First SSL Auditing
Inspect the certificates your
CDN hides.
Most checkers only see the edge. CheckYourCert talks directly to your Origin IP to verify backend security before it causes a 526 error.
Connection PathDirect IP Auditing
- • Establishing TLS Handshake with 1.2.3.4
- • Sending SNI Extension: example.com
- • Certificate Received: Handshake Successful
Why Check the IP?
Modern infrastructure uses proxies to hide backend servers. While this is great for security, it makes SSL debugging nearly impossible.
- ✓
Detect Misconfigurations
Find nodes with missing intermediate certificates.
- ✓
Zero-Downtime Migration
Test your new server's SSL before updating DNS.
