Registered to Oracle Application Server HTTPS, and in practice a general-purpose "HTTPS when 443 is taken" port.
IANA's name for 7443 is oracleas-https, from the Oracle Application Server era. What you actually meet on a scan is a TLS listener that some appliance, Java application server, or reverse proxy was pointed at because 443 was already in use or because the process runs unprivileged. The port carries no protocol meaning of its own: the useful information is in the TLS handshake and the certificate, which will name the real service. Treat it exactly as you would 8443.
Expose with care
TLS on the wire says nothing about what is behind it — non-standard HTTPS ports very often front an admin console that was never meant to be reachable from the internet.
