Certificate Transparency Log Monitor
Track new SSL/TLS certificates issued globally via public CT logs. Detect rogue certificate issuance for your domains before attackers can exploit them.
What is Certificate Transparency?
Certificate Transparency (CT) is an open framework that requires all publicly-trusted Certificate Authorities to log every SSL/TLS certificate they issue to publicly-auditable, append-only logs.
This means that if a CA mis-issues a certificate for your domain — whether through a compromise, social engineering, or error — you can detect it within hours, not months.
Google Chrome, Firefox, and Safari all require valid CT proofs (Signed Certificate Timestamps) before trusting a certificate.
Detect Rogue Certificates
Know immediately if any CA issues a certificate for your domain without your authorization.
Public & Auditable
CT logs are cryptographically verifiable and publicly accessible — anyone can audit them.
Required by Browsers
Since 2018, Chrome requires all new certificates to appear in CT logs or they won't be trusted.
Early Warning System
Get notified of suspicious certificate issuance before attackers can use them against your users.
