Sofia wants to replace FTP traffic with a secure replacement. What secure protocol should she select instead?

Both FTPS and SFTP are commonly used as secure replacements for insecure FTP services. SFTP offers the advantage of using SSH for transfers, making it easy to use existing firewall rules. TFTP is trivial FTP, an insecure quick transfer method often used to transfer files for network devices. HFTPS and SecFTP were made up for this question.
