Developer-First SSL Auditing

Inspect the certificates your CDN hides.

Most SSL checkers only see the CDN edge. SSLCertify connects directly to your origin server to verify its TLS certificate.

  • Optional — use this to test origin servers behind a CDN or load balancer.
  • Detect expiry, chain issues, and configuration problems.
  • Prevent production TLS errors and downtime during zero-downtime migrations.
Live TLS Handshake(Origin IP)
Direct IP Auditing
  • Establishing TLS handshake with 1.2.3.4
  • Sending SNI Extension: example.com
  • Certificate Received: Handshake Successful

Why Validate Origin Certificates?

  • CDN and proxy layers often mask origin TLS failures until traffic is live.
  • Certificate chain issues at the origin can surface as opaque CDN errors.
  • Misconfigured origin certificates cause hard-to-debug production outages.
  • Errors commonly appear as Cloudflare 526, Akamai 30.xx, Fastly TLS failures, or load balancer handshake errors.

Common Use Cases

Built for engineers debugging real-world TLS & CDN issues.

Origin Certificate Validation

Validate TLS certificates on backend servers hidden behind CDNs or proxies.

Load Balancer Audit

Verify that every backend behind a load balancer presents a valid and complete certificate chain.

Zero-Downtime Migration

Test new origin servers before DNS or traffic cutover.
