SSL & domain expiry monitor
Get notified before your SSL certificate or domain expires.
Expired SSL certificates and lapsed domain registrations are preventable causes of outages. StatusOwl monitors both so you never get caught off guard.
SSL certificate monitor
When you add an SSL monitor, StatusOwl connects to the TLS handshake of your domain and reads the certificate chain. It checks:
- Certificate validity (not expired, not self-signed by default).
- Days remaining until expiry.
- Certificate chain completeness (no missing intermediate certs).
Domain expiry monitor
StatusOwl queries WHOIS data for your domain and tracks the registration expiry date. Because WHOIS rate-limits are strict, domain checks run once every 12 hours rather than the standard check interval.
Private WHOIS registrations (common with Cloudflare Registrar, NameSilo, etc.) may not expose expiry dates. In that case, check your registrar dashboard directly.
Alert thresholds
Configure how many days before expiry you want to be alerted. Defaults are 30 days and 7 days. You can add custom thresholds for each monitor.
