SSL Certificate Monitoring

FlareWarden automatically monitors SSL certificates for all HTTPS uptime monitors. Get alerts before certificates expire and when certificates change unexpectedly.

Discover subdomains you may not be monitoring yet
  • Detect unauthorized certificates issued for your domain
  • Track certificate renewals across all your subdomains

    CT Discovery runs periodically in the background and adds newly discovered subdomains to your SSL tracking automatically.

  • Webhook Events

    SSL events trigger webhooks for integration with your tools

    SSL events can also trigger webhooks for integration with your tools:

    ssl.expiring - Certificate expiring soon

    ssl.expired - Certificate has expired

    ssl.changed - Certificate changed

    Best Practices

    • Use auto-renewal: Let's Encrypt and most providers offer automatic renewal
    • Set generous thresholds: 30 days gives you time to troubleshoot auto-renewal issues
    • Monitor subdomains: Each subdomain needs its own certificate (unless using wildcards)
    • Track certificate changes: Unexpected changes could indicate security issues
