Every cert issued by a public CA is logged. We query those logs for your root and pull back every subdomain that's ever had a cert.
Each subdomain gets a fresh TLS handshake. You see the issuer, validity window, and whether the certificate even matches.
Just a domain name. The staging box someone stood up in 2022 surfaces alongside production — without you knowing it existed.
