For transferring large, sensitive data to a CSP, which method best balances efficiency and security for a 40 TB dataset?

• A. Online transfer over VPN
• B. Compressed data transfer over SFTP
• C. Plain transfer over FTP
• D. Move the data to encrypted drives and use the CSP-certified shipping provider.

Answer: (D)

When dealing with a very large, sensitive dataset, the goal is to protect the data while delivering it to the cloud provider efficiently. For 40 TB, online transfers can be slow and bandwidth-limited, increasing the time to move the data and the window of exposure if any part of the path is compromised. Shipping encrypted drives to a CSP-certified carrier combines strong data protection with practical transfer speed: the data is encrypted on the media, you benefit from the carrier’s documented security and chain-of-custody, and the CSP can securely ingest the media upon arrival. This approach minimizes exposure since the data is encrypted at rest on the drives and remains protected during transit, while also leveraging secure, compliant handling from a trusted provider. In contrast, transferring over a VPN, even with compression, depends on network capacity; plain FTP is insecure; and compressed SFTP still hinges on available bandwidth and continuous connectivity. So physically moving encrypted drives via a CSP-certified shipping provider offers the best balance of security and efficiency for a 40 TB dataset.
