Cert Spotter is a Certificate Transparency log monitor developed by SSLMate that tracks SSL/TLS certificate issuance for specified domains. The tool monitors Certificate Transparency logs and sends alerts when new certificates are issued for monitored domains. It operates without requiring a database setup, making it simpler to deploy compared to other open source CT monitoring solutions. Cert Spotter includes a specialized certificate parser designed to ensure comprehensive certificate detection without missing entries. The tool can identify various security scenarios including certificates issued by attackers who have compromised DNS infrastructure, taken over abandoned subdomains, compromised certificate authorities, or violated corporate certificate policies. The tool is available both as a self-hosted open source solution and as a managed service through SSLMate. The hosted version provides a web dashboard for centralized certificate management and monitoring. Cert Spotter requires Go version 1.19 or higher for installation and operation. It serves as a security monitoring tool for organizations that need to track certificate issuance across their domain infrastructure.
