Know when a renewal fails — before the certificate expires
NetworkAI checks your TLS certificates, domain registrations and DNS records every day, and alerts you when a certificate has passed its renewal point without being replaced.
Every day, for every domain you add
TLS expiry
Reads the live certificate off the handshake — including already-expired ones — and tracks days remaining.
Chain & hostname
Verifies the full chain validates and that the hostname matches the certificate's names.
Revocation
Checks whether the certificate has been revoked, using the CRL published in the certificate.
Key & signature
Reports key algorithm and size and the signature algorithm, so weak keys and SHA-1 signatures stand out.
Domain registration
Reads the registration expiry through RDAP, with a WHOIS fallback for registries that don't publish RDAP.
DNS records
Confirms the A, CNAME and MX records you depend on are still present.
An alert means a renewal actually failed
With certificates moving from 398 days toward 47, a fixed '30 days before expiry' reminder fires on nearly every cycle until you ignore it. NetworkAI tracks each certificate's lifetime and alerts when it has passed its expected renewal point — under a third of its life left — and no new certificate has appeared.
- Renewal-failure alert: past the renewal point with no replacement certificate
- Safety net: always alerts at 7 days and 1 day before expiry, even if everything else looks fine
- One alert per certificate and threshold — a successful renewal resets the state
- Delivery by email on every plan; Slack and signed webhooks on Pro
