Category: security

Tags: ssl, certificate-transparency, subdomain-discovery

Score: 4.3/10 (Innovation: 3, Technical: 4, Documentation: 3, Utility: 6)

This project provides a free web tool that discovers all subdomains for a given domain by querying public Certificate Transparency logs, then audits each subdomain's TLS certificate. It's interesting as a practical security utility for uncovering forgotten or misconfigured certificates without requiring registration.

Target audience: devops, security engineers, system administrators
