Secure File Transfer Export Connector

Transmit documents and index data to remote sites over a secure and encrypted connection.

Service providers or companies with remote scan sites often need to transmit documents over an internet connection.

However, documents transmitted over the web can be intercepted which poses a security risk. For transmitting sensitive or confidential document images and data, a secure and encrypted connection is necessary. The CaptureBites Secure File Transfer Connector transmits documents and index data over Secure FTP and supports both the S-FTP and FTP-S encryption protocols. The connector can also transmit over standard FTP without encryption for maximum compatibility.

Capabilities of the current version:

  • Connect button to test the connection with the FTP server
  • Browse button to navigate directly  to a folder on the FTP server
  • Folder and subfolders can be created with all supported protocols
  • Supports both TIFF and PDF output
  • The PDF setup allows to define a PDF open and PDF permissions password

FTP or Secure FTP?
The major reason for implementing Secure FTP versus FTP is obviously security. During a standard FTP session, your username and password are transmitted in clear text. In FTP all data is passed back and forth between the client and server without the use of encryption. This makes it possible to listen in and retrieve your confidential information including login details.

SFTP (Secure File Transfer Protocol) is a secure replacement for FTP (File Transfer Protocol) based on the Secure Shell protocol (SSH). Unlike FTP, SFTP encrypts both commands and data providing effective protection against network security risks. SFTP encrypts the session, preventing the detection of your username, password or anything you’ve transmitted.

With SFTP all the data is encrypted before it is sent across the network.

FTPS is not the same as SFTP. FTPS implements the original FTP protocol through a separate secure tunnel. FTPS (FTP-SSL) is a standard FTP that uses TSL/SSL (TSL = Transport Layer Security/SSL = Secure Socket Layer) to encrypt the control session and if required the data session.  In summary, SFTP is an SSH file transfer and FTPS is FTP with SSL, FTPS is a file transport layer on top of SSL or TLS. FTP-S adds SSL-enabled FTP send and receive capabilities, uses the FTP protocol to transfer files to and from SSL-enabled FTP servers.

As usual, the answer depends on what your goals and requirements are. In general, SFTP is technically superior to FTPS. Of course, it’s a good idea to implement support for both protocols, but they are different in concepts, in supported commands, and in many other things.

It’s a good idea to use FTPS when you have a server that needs to be accessed from personal devices (smartphones, PDAs, and the like) or from some specific operating systems that have FTP support but don’t have SSH/SFTP clients. If you are building a custom security solution, SFTP is probably the better option.

As for the client side, the requirements are defined by the server(s) that you plan to connect to. When connecting to Internet servers, SFTP is more popular because it’s supported by Linux and UNIX servers by default.

For private host-to-host transfer, you can use both SFTP and FTPS. For SFTP support, you can install an OpenSSH package that provides free client and server software.

These are the settings of the CaptureBites Secure File Transfer Connector.
