An SSL certificate encrypts the connection between your website and visitors. We offer three tools to help you verify everything is configured correctly.
1. SSL Checker
Our SSL Checker validates the complete certificate chain — your certificate, intermediate CA, and root CA. If the chain is broken, browsers will reject the connection.
2. SSL Expiry Checker
Use the SSL Expiry Checker to see exactly when your certificate expires. Most certificates last 90 days (Let's Encrypt) or 1 year (commercial CAs). An expired certificate shows visitors a scary browser warning.
3. Security Headers
SSL alone isn't enough. The Security Headers Checker audits headers like HSTS, X-Frame-Options, and Content-Security-Policy to ensure your site follows security best practices.
What to Check
- Expiration date — Set a reminder before it expires
- Certificate chain — Must be complete and valid
- Domain coverage — Both
example.comandwww.example.comshould be covered - Protocol support — TLS 1.2 and 1.3 should be enabled; disable older versions
- Security headers — HSTS should be configured to force HTTPS
Run all three checks whenever you deploy a new certificate or change server configuration.
