 Cert Spotter is a Certificate Transparency log monitor from SSLMate that

+alerts you when an SSL/TLS certificate is issued for one of your domains.
 Cert Spotter is easier than other open source CT monitors, since it does
 not require a database.  It's also more robust, since it uses a special
 certificate parser that ensures it won't miss certificates.
