SSL Certificate Monitoring

An expired certificate instantly breaks trust: browsers show a full-page warning and most APIs refuse the connection. SiteFlux watches every certificate your monitors touch so you can renew weeks in advance.

What we check

• Days until expiry, with early warnings at 30, 14 and 7 days
• Issuer and chain changes, including unexpected re-issuance
• Hostnames covered by the certificate (SAN mismatch detection)
• Protocol and cipher health for each monitored endpoint

Alerts before it matters

Expiry alerts are delivered through the same escalation channels as downtime alerts: email, SMS, Telegram and phone calls. Combined with uptime history, you get a complete security-relevant timeline for every domain.
