File Transfer Protocols

Serv-U MFT Server provides RFC-compliant implementations of FTP, FTPS (via SSL/TLS), SFTP (via SSH2) for FTP client, SSH client and automated file transfers, plus HTTP/S for web transfers, mobile transfers, and web administration.

 

File Transfer Protocol Guide

The five file transfer protocols Serv-U supports each have their own advantages and disadvantages. Use the following chart to help determine which protocols you should support in your deployment.

  FTP FTPS SFTP HTTP HTTPS
Automated or Scripted Transfer*
Legacy or Mainframe Access *1 *1
Secure Transfer
Strong Authentication (2 Factor)
"Anywhere Access" (Mobile or Web)
Single Firewall Port
Native Windows Client
Native Linux/Unix Client *2 *2

* Serv-U offers file transfer scheduling using FTP Voyager.
1 = Some legacy systems have FTPS or SFTP clients; check with your local administrators.
2 = HTTP/S web browsers are usually available on Linux/Unix platforms when they are shipped with a GUI interface.
