A typical use scenario for SSH Tectia Client with EFT Expansion Pack is to integrate it to an existing application through the SFTP API, for example to an application responsible for data warehouse feeds, extranet applications, Windows desktop applications, or third-party file transfer management applications. This scenario requires an SSH Tectia Server with EFT Expansion Pack or with SSH Tectia Server with Tunneling Expansion Pack.

In this use scenario, an end user needs to be able to download files from servers that are located on the Internet. However, direct access from the user workstations to those servers is not possible because of security reasons. Thus, the end users use a web access control application located on the extranet. This application manages access rights to individual servers and files.

When the end user has selected the files to download, the web application triggers file transfer through the API. SSH Tectia Client with EFT Expansion Pack then transfers the file to the extranet and the user is provided an HTML link to the file.

With this solution, end users are not accessing external services and it is easy to manage access rights from a centralized web server. External parties do not have to modify their systems but can rely on the trusted Secure Shell standard.
