Why CRL Monitoring Matters

For the status of a certificate to be determined, an up-to-date CRL must be available to the users of your PKI. If the CRL is not available or is stale (has expired), relying systems will start to fail, potentially causing widespread outages. CRL Monitor helps prevent these issues by continuously checking your CRLs for freshness and availability.

Proactive Alerting

Prevent serious incidents by receiving timely email alerts before problems affect your systems.

  • Alerts if a CRL is not fresh
  • Alerts if a CRL is not available
  • Alerts if a CRL is corrupted
  • Supports multiple recipients

Detailed Reporting

Each time CRL Monitor runs, it generates comprehensive reports with detailed information about your CRLs.

  • Issuer information
  • Expiration dates
  • Next update times
  • Revocation statistics
