Name a method to securely transmit files for conversion.

Using SFTP (Secure File Transfer Protocol) is a secure method to transmit files for conversion because it provides a secure channel for transferring data over the network. SFTP encrypts both the commands and the data being transferred, which protects sensitive information from being intercepted by unauthorized parties during transmission. This is particularly important when handling sensitive or confidential information, as it helps maintain data integrity and confidentiality.

In contrast, emailing files directly poses significant security risks; emails can be intercepted, and attachments are often not encrypted. Filing files in cloud folders may not inherently provide security, as access controls and encryption depend on the specific cloud service used. Sending files via FTP without security measures is also risky because FTP transfers data in plaintext, making it vulnerable to interception and unauthorized access. Therefore, using SFTP is the most secure choice for transmitting files.
