There are many benefits to using SFTP to transfer files over the internet. SFTP was purpose-built to ensure the safe and secure transfer of data. These built-in security features include single-port transfer to reduce attack points, data encryption, authentication via SSH as well as username/password, and data integrity and authentication checks. Advanced features of SFTP include the ability to pause and resume a file transfer, as well as allowing users to remotely perform basic admin tasks. Finally, unlike other file transfer protocols, SFTP transfers file metadata (file size, date, time, and permissions) by default.
