How it works

Automatic SSL monitoring for every site

StatusPage.me keeps an eye on your certificates in the background and emails you before anything breaks.

What we check
  • Certificate validity and full chain (including intermediates)
  • Exact expiration date and days remaining
  • Common Name (CN) and issuer details
  • TLS handshake success so browsers can actually load your site
When we alert you
  • Automatic email alerts 30, 14, 7 and 1 day before expiry (configurable per monitor)
  • Immediate alerts when a certificate is already expired
  • Alerts when the TLS handshake fails and your HTTPS endpoint is not reachable
  • Each alert includes domain, port, expiry date, issuer and a direct link to manage the monitor

SSL checks run automatically every 6 hours for all plans, including the Free tier.

Why it matters

SSL failures are SEO and trust emergencies

An expired certificate doesn't just break your site — it destroys user confidence and search engine ranking simultaneously.

For certificate health in the wider reliability stack, explore the University uptime monitoring guides.

  • SEO Protection: Search engines penalize sites with invalid security certificates.
  • User Trust: Browsers display scary warnings when certificates expire.
  • Chain Validation: We check intermediate certificates to ensure the full chain is valid.
