Certificate Transparency log monitor

Back to search · Project homepage

Description

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 to use 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. You can use Cert Spotter to detect: - Certificates issued to attackers who have compromised your DNS and are redirecting your visitors to their malicious site. - Certificates issued to attackers who have taken over an abandoned sub-domain in order to serve malware under your name. - Certificates issued to attackers who have compromised a certificate authority and want to impersonate your site. - Certificates issued in violation of your corporate policy or outside of your centralized certificate procurement process. N.B. Cert Spotter fetches the entire set of CT logs, using a large amount of bandwidth while doing so, possibly for a week or more.
