Monitoring
Expiration Tracking, Issuer Validation & Chain Verification
Stop relying on calendar reminders to renew your SSL certificates. BigBell tracks expiration dates, certificate chains, and issuer validity, alerting you weeks before a certificate expires.
What is SSL Certificate Monitoring?
SSL/TLS Certificate monitoring is the automated tracking of the digital certificates that secure your websites and APIs. The monitoring tool connects to your secure endpoints, downloads the public certificate, and analyzes its metadata. It tracks the exact expiration date, verifies the certificate chain of trust, checks the issuing Certificate Authority (CA), and ensures the hostname matches the certificate's Subject Alternative Name (SAN).
Why SSL Certificate Monitoring Matters
An expired SSL certificate is a highly visible, embarrassing, and costly outage. When a certificate expires, modern web browsers completely block users from accessing the site, throwing a massive, scary 'Your connection is not private' warning. Even if you use automated tools like Let's Encrypt, auto-renewal scripts can silently fail. SSL monitoring provides an independent, foolproof safety net, alerting your team weeks (and days) before an expiration event occurs.
- ✓Prevent embarrassing downtime from expired certificates
- ✓Catch failed Let's Encrypt auto-renewals early
- ✓Detect unauthorized certificate issuance (rogue CAs)
- ✓Ensure the full intermediate certificate chain is valid
Core Use Cases
Used by IT departments to manage hundreds of certificates across corporate infrastructure, by DevOps teams to verify automated SSL provisioning pipelines, and by security teams to ensure no unauthorized certificates have been issued for their domains.
Complete SSL Monitoring Capabilities
Expiration Countdowns
Track exactly how many days are left until expiration. Set tiered alerts (e.g., 30 days, 14 days, 3 days).
Chain of Trust
Verify that all intermediate certificates are correctly installed, preventing 'Untrusted Issuer' errors on mobile devices.
Issuer Tracking
Monitor the Certificate Authority (CA). If your certificate is suddenly re-issued by an unknown CA, receive an immediate security alert.
Hostname Validation
Ensure the certificate being served actually matches the domain name requested, catching misconfigured load balancers.
