SSL Certificate Expiry Monitoring
You check the cert manually when you think of it. That works until a busy stretch happens and you don't think of it for six weeks. The browser warning shows up before you do.
Expiron monitors SSL cert expiry by reading the live certificate on each domain — no agent, no configuration per server. Add the domain and it handles the rest.
Checks run every 24 hours. Alerts go to email or Slack at 60, 30, 14, 7, and 1 day before expiry. If you manage domains across multiple clients or systems, the client dashboard organizes everything so an alert tells you exactly what it belongs to.
- Direct cert reading over HTTPS — no agent install, no server access required. Add a domain name and monitoring starts.
- 60-day lead time on Pro — you're scheduling a renewal, not reacting to an outage.
- Works with any SSL provider: Let's Encrypt, Cloudflare, DigiCert, Sectigo, ZeroSSL, or any issuer.
Common questions
- What SSL providers does it work with?
- All of them — Expiron reads the live cert directly, so provider doesn't matter.
- How do I add a domain?
- Type the domain name and add it. No config files, no agent install.
- What if I have wildcard certs?
- Wildcard certs show as one expiry date. Add the root domain and Expiron reads the cert.
- Does it catch cert chain issues?
- Expiron tracks expiry dates specifically. General SSL health validation is outside scope.
