Prior to the IETF's involvement, SFTP was a proprietary protocol of SSH Communications Security, designed by Tatu Ylönen with assistance from Sami Lehtinen in 1997. After a seven-year hiatus, in 2013 an attempt was made to restart work on SFTP using the version 3 draft as the baseline. Eventually, development stalled as some committee members began to view SFTP as a file system protocol, not just a file access or file transfer protocol, which places it beyond the purview of the working group.

As development work progressed, the scope of the Secsh File Transfer project expanded to include file access and file management.

The software industry began to implement various versions of the protocol before the drafts were standardized. Internet Drafts were created that successively revised the protocol into new versions. The Internet Engineering Task Force (IETF) working group 'Secsh' that was responsible for the development of the Secure Shell version 2 protocol (RFC 4251) also attempted to draft an extension of that standard for secure file transfer functionality. This is an advantage over the common FTP protocol. Uploaded files may be associated with their basic attributes, such as time stamps. An SFTP client willing to connect to an SSH-1 server needs to know the path to the SFTP server binary on the server side. Running an SFTP server over SSH-1 is not platform-independent as SSH-1 does not support the concept of subsystems.

It is possible, however, to run it over SSH-1 (and some implementations support this) or other data streams. SFTP is most often used as subsystem of SSH protocol version 2 implementations, having been designed by the same working group. The protocol itself does not provide authentication and security it expects the underlying protocol to secure this. It is sometimes confused with Simple File Transfer Protocol. SFTP is not FTP run over SSH, but rather a new protocol designed from the ground up by the IETF SECSH working group. In SFTP, the file transfer can be easily terminated without terminating a session like other mechanisms do. The file transfer is fast in SCP when compared to the SFTP protocol due to the back and forth nature of the SFTP protocol. While SCP is most frequently implemented on Unix platforms, SFTP servers are commonly available on most platforms. SFTP attempts to be more platform-independent than SCP with SCP, for instance, the expansion of wildcards specified by the client is up to the server, whereas SFTP's design avoids this problem. An SFTP client's extra capabilities include resuming interrupted transfers, directory listings, and remote file removal. It is also available for z/OS.Compared to the SCP protocol, which only allows file transfers, the SFTP protocol allows for a range of operations on remote files which make it more like a remote file system protocol. It is commercially supported, with 24x7 support available. Tectia SSH is a widely used server for Windows.

OpenSSH is a free open source server for Unix/Linux, and comes standard with every modern Unix, Linux, and Mac system.

For Windows, FileZilla Server is a possible alternative. However, if one is needed, all Unix and Linux systems come with built-in FTP servers.

We do not recommend configuring FTP servers. Public companies are also required to protect financial data.Ĭonsequently, the use of FTP should be restricted to totally closed and trusted environments and anonymous access. It is practically impossible to achieve regulatory compliance in regulated industries, such as financials or health care, when using FTP. It also makes configuring automation much easier and supports secure key-based authentication. It is supported on all modern operating systems. Practically all commercial file transfer tools now support SFTP. Secure File Transfer Protocol (SFTP) is the alternative the world has moved to. We strongly recommend switching away from FTP as soon as possible. Contents Secure Alternative (SFTP) Implementations Secure Alternative (SFTP)
