SFTP Servers is a popular Secure File transfer protocol that is one of the most popular protocols for file transfers.
Over the last few years, secure versions of FTP called SFTP and FTPS have come up and replaced FTP due to its added layer of security.
FTPS is File Transfer Protocol Secure that negotiates through an encrypted TLS tunnel to transfer data. On the other hand, SFTP is not really a FTP server, rather it is an SSH server that also understands FTP commands.
As a result, SFTP prevents the unencrypted transfer of login credentials and at the same time, it also generates a unique identifier that has to be transmitted back from the client to complete the transfer. Due to these measures, you can rest assured that your file transfers will be safe with SFTP.
