SSL & Domain Expiration

Oack automatically monitors SSL certificate and domain registration expiration for every active HTTP monitor. A daily sweep checks:

• SSL certificates — TLS handshake reads the leaf certificate's expiration date.
• Domain registration — RDAP protocol (the ICANN standard replacement for WHOIS) checks registration expiry.

Notifications are sent through your linked alert channels at configurable thresholds (default: 30, 14, 7, and 1 days before expiration). Available on Pro and Business plans.
