See Who’s Issued SSL/TLS Certificates to Your Domain Name

Certificate Transparency (CT) Searching gives organizations an opportunity to review SSL/TLS certificates that have been issued in their name. Entrust records all SSL/TLS certificates that we issue to the CT logs. This practice promotes transparency and provides an open way for domain owners to audit and monitor certificates that have been issued in their name.
