A client has Quickbooks Desktop and wants to move the database to a cloud provider. How is/can the connection between clients and the server encrypted?

Because client connections will transfer data to and from a cloud-hosted server using insecure networks, I'm asking if Quickbooks natively encrypts data between desktop clients and the Quickbooks Database Server using SSL/TLS or some other protocol.

If not, is there a recommended best practice or product set to encrypt this connection?

What have other people used? What have been your experiences with your solution? Any tips and warnings?

Thanks in advance.
