Overview​

SFTP, short for SSH File Transfer Protocol, is a secure file transfer protocol that runs over SSH connections.

It matters because it provides encrypted remote file access and transfer in environments where plain FTP is not acceptable.

What SFTP Does​

SFTP allows users and tools to:

  • upload and download files
  • browse remote directories
  • rename, move, and delete remote files
  • manage file permissions in some environments
  • transfer data over an encrypted SSH connection

Although people often treat it simply as "secure file transfer," SFTP is more than a raw upload protocol because it supports remote file-management operations too.

Why SFTP Matters​

SFTP matters because it replaces insecure transfer habits with encrypted access.

Compared with plain FTP, it protects:

  • credentials
  • transferred file content
  • session traffic

That is why SFTP is common in hosting, server maintenance, deployment support workflows, and remote content operations.

SFTP vs FTP and SCP​

SFTP is often confused with other transfer protocols.

  • SFTP runs over SSH and supports remote file operations.
  • FTP is older and unencrypted unless extra layers are added.
  • SCP also uses SSH transport, but it is more narrowly focused on copying files rather than interactive remote file management.

In practice, SFTP is often the preferred option when a user needs secure, general-purpose file access to a server.

Common SFTP Tools​

SFTP can be used through:

  • command-line clients
  • GUI tools such as WinSCP
  • IDE integrations
  • automation scripts

That makes it useful in both developer-oriented and less terminal-heavy workflows.

Frequently Asked Questions​

Is SFTP the same as FTP?​

No. SFTP is a different protocol that runs over SSH and provides encrypted transfer and remote file management.

Is SFTP the same as SSH?​

Not exactly. SFTP runs over SSH transport, but SSH is the broader secure remote access protocol.

Do you need a GUI to use SFTP?​

No. SFTP can be used from a CLI or through GUI clients such as WinSCP.
