First notification sent to your designated certificate owners. Includes certificate subject, issuer, SAN list, and exact expiry timestamp in UTC. Example: api.statpool.io — Let's Encrypt R3 — expires 2025-09-12 23:59:59 UTC.

Escalated alert to your DevOps channel. Automatically includes a renewal checklist and links to your internal runbook. If auto-renewal is configured via ACME, the check still fires as a verification step.

High-priority notification routed to on-call engineers via PagerDuty or VictorOps. If the certificate is part of a critical path — e.g., checkout.mystore.com — the alert is tagged as P1 with automatic incident creation.

Final escalation to management and security leads. Includes a summary of all certificates expiring within 48 hours across the entire account. If a cert expires without renewal, a post-mortem ticket is auto-generated.

Every check verifies the complete chain from leaf certificate to root CA. Broken chains, missing intermediate certificates, or self-signed certs in production are flagged immediately. For example, a missing DigiCert Global Root G2 intermediate will trigger a critical alert before browsers start showing warnings.

Automatically identifies certificates using deprecated algorithms — SHA-1 signatures, RSA keys shorter than 2048 bits, or ECDSA curves below P-256. A cert on legacy.internal.corp signed with SHA-1/RSA-1024 will be flagged as non-compliant on first scan.

Compares the certificate's Subject Alternative Names against the monitored hostname. If app.example.com presents a cert that only covers *.example.com without the bare domain, you'll get a mismatch alert — preventing silent TLS errors for health-check probes and internal clients.

Export monthly compliance reports in PDF or CSV showing every certificate's status, key length, signature algorithm, and days-to-expiry at time of check. Reports are timestamped and immutable, ready for SOC 2 Type II or PCI DSS v4.1 evidence submissions.
