The Transition to Short-Lived SSL Certificates
Modern browser security standards (promoted by Google Chrome, Mozilla Firefox, and Apple Safari) have shortened SSL certificate validity periods to improve cryptographic agility. If an automated renewal job fails, visitors will be greeted with an untrusted certificate warning.
Key Checklist for HTTPS Health:
- Certificate Issuer: Ensure trusted Root CAs (Let's Encrypt, DigiCert, Sectigo).
- Cipher Suites: Enforce TLS 1.2 and TLS 1.3 exclusively to prevent legacy vulnerability exploits.
- HSTS Enforcement: Implement HTTP Strict Transport Security headers to guarantee end-to-end encryption.
Use our free built-in SSL Health Inspector tool to check certificate expirations, cipher validity, and DNS records anytime.
