Yes, you can use your own domain to access your dedicated NC-Service instance, e.g. privatecloud.company.com.

RCA Systems will provide the IP address to which to associate the DNS registry and, on request, can also manage all TLS certificate operations, using the Let's Encrypt system.

If, on the other hand, the customer is already in possession of a TLS certificate and the relative key, it can be used by sending it to RCA Systems for application in the system.
