Inspect a public host on TCP port 443 for certificate expiry, DNS names, fingerp
Inspect a public host on TCP port 443 for certificate expiry, DNS names, fingerprint, runtime CA/hostname validation and negotiated TLS details. A failed certificate check triggers one unverified diagnostic handshake and remains untrusted. No HTTP scanning, revocation or exhaustive security assessment.
