SFTP is a client-server protocol that can be launched either as a command line or through a graphical user interface (GUI). Techopedia Explains Secure File Transfer Protocol This term is also known as Secure Shell (SSH) File Transfer Protocol. A private user may want to encrypt his or her communications as well. So a business user might use SFTP to transmit files containing trade secrets or other similar information. For example, trade secrets may not be covered by any particular data privacy rule, but it can be devastating for them to fall into the wrong hands. SFTP can be handy in all situations where sensitive data needs to be protected. Since the client needs to be authenticated by the server, SFTP also protects against man-in-the-middle attacks. ![]() SFTP transfers files security using SSH and encrypted FTP commands to avoid password sniffing and exposing sensitive information in plain text. SSH and SFTP were designed by the Internet Engineering Task Force (IETF) for greater web security.

VanDyke Software offers the highest level of security for your data in transit by supporting the protocol recognized as the industry standard: Secure Shell (SSH2). SecureFX can also connect to legacy systems that do not recognize any newer, secure protocol using standard FTP. However, SecureFX also allows flexibility in file transfer operations through support for other secure file transfer protocols, including SCP and FTP over SSL. SecureFX supports Secure Shell (SSH2) File Transfer Protocol, allowing secure file transfers when connected to a Secure Shell server, like VanDyke Software's VShell®. SecureFX Supports SFTP and other Secure Protocols Secure file transfer using SFTP requires both the client and remote system to recognize the protocol. Data integrity: data has not been altered in transit.Data encryption: data is protected from eavesdropping or packet sniffing.Host authentication: a secure file transfer client is communicating with a known host.User authentication: only verified users have access to files, file systems, and remote machines.File transfers performed using SFTP apply protection measures to ensure: SSH2 improves secure file transfer capabilities by utilizing an entirely new protocol-Secure Shell (SSH2) File Transfer Protocol, or SFTP (rather than standard FTP) to protect data in transit between a file transfer client and remote server. SSH1 made strides toward secure file transfer by using port forwarding (data tunneling) to provide a layer of security for file transfers performed using FTP (standard File Transfer Protocol), which transmitted all data, including usernames and passwords, in the clear. How Secure Shell (SSH)-Enabled Secure File Transfer Works The second version (SSH2), an open protocol developed by the Internet Engineering Task Force (IETF), was submitted in 1997 and improves upon SSH1, making it less vulnerable to various threats and providing a more robust file transfer solution. ![]() The first version of Secure Shell (SSH1), adopted in 1995, was intended to replace non-secure commands native to UNIX-like systems (e.g., RLogin, rsh, and rcp) to enable secure remote access and file transfer, thereby providing businesses with a time- and cost-efficient way to use the Internet for information exchange without compromising privacy. SecureFX ®, VanDyke Software's file transfer client, supports the Secure Shell protocol, the industry standard to provide network and data security over public Internet connections.
