CT logsCertificate monitoring
Know about every certificate issued in your name.
Every publicly trusted TLS certificate is recorded in certificate transparency logs. Nulink monitors those logs for your domains, so you see new hostnames the moment a certificate is issued, spot certificates you didn't request, and get warned before one expires.
What it finds
- Newly issued certificates for your domains
- Certificates from authorities you don't normally use
- Certificates that are expiring or have expired
- Weak keys and outdated TLS configurations
