What are the acceptable data transmission methods to allow client data to be uploaded to the OPS-COM system?

The acceptable data transmission methods to allow client data to be uploaded to the OPS-COM system are strong cryptography and security protocols to safeguard sensitive data during transmission over open, public networks, and enabling TLS whenever cardholder data is transmitted or received. Any traffic uploaded or downloaded to the service would be encrypted with Transport Layer Security (TLS). eg. HTTPS (web/API) SFTP (secure FTP). Generally data will use one of these protocols. In some cases data will pass been SQL servers using encryption (utilizing TLS).
