Why do we use SFTP for file transfer?

[Abhiram.m]

Secure File Transfer Protocol (SFTP) is a network protocol for securely accessing, transferring, managing large files and sensitive data. SFTP is used for transferring files over Transport Layer Security and the transfer of data for virtual private network (VPN) applications with high security.

It uses SSH to transfer the files and requires that the client be authenticated by the server.
