Expired SSL Certificates
Passive analysis of SSL certificates to identify expired ones that break user trust, trigger browser warnings, and may expose communications.
Key capabilities
Certificate inventory
Builds a complete inventory of every SSL/TLS certificate across your domains and subdomains, tracking issuer, validity dates, and chain health.
Expiry alerting
Alerts in advance when certificates are approaching expiry so your team can renew before users see browser warnings.
Wildcard and SAN coverage
Tracks wildcard certificates and Subject Alternative Name coverage to ensure all subdomains are properly protected.
Revocation monitoring
Detects certificates that have been revoked by the issuing CA, which can indicate compromise or misconfiguration.
Why it matters
An expired certificate is one of the most visible and preventable security failures. It erodes customer trust instantly and can break critical integrations.
