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.
