OS4X consists of several parts and is individually configurable.

OS4X Core

As a solution for the automated file-based data transmission, OS4X Core offers a rich set of functionality, such as the integrated certificate management, automation tasks such as the directory scanner, poll queue and other administratively interesting mechanisms. Administration is done via an HTML5 web interface with a desktop-like application feeling. Within this interface, you can setup all partners, investigate logs, configure automatism and many other things.

OS4X Enterprise

OS4X Enterprise offers a lot of more plugins for OS4X Enterprise, such as (de-)compression of ZIP, TAR, gzip and other formats. ComSecure, a security product for the communication with VW/Audi, is completely integrated in OS4X. Mail notifications inform about processes, and in addition a transmission PDF plugin offers the configurable possibility to add such a transmission report to the sender's job (optionally sent via email). The list of plugins is not limited, so you are free to implement and add own plugins.
All features of OS4X Core are included!

OS4X OFTP2 SmartProxy

The OS4X OFTP2 SmartProxy allows you to communicate via OFTP2 in a professional network environment over a DMZ. Security options allow to open connections from inside (the application zone) to the outer zone, but not the other way. With the OS4X OFTP2 SmartProxy, you can receive incoming OFTP2 connections securely, allowing to verify the session parameter, even single OFTP2 packages are examined optionally. Client connection can be verified by partner station information, given in the connection client certificate. Support for OFTP1.x ist explicitely configurable, so you can use the proxy for both protocols.


With the free OS4Xvirtual appliance, you start instantly with OS4X! Download, import and run the virtual machine, which offers an updated OS4X installation! An installation wizard helps you to setup the machine, all interaction can be done interactively with web interfaces, so there is no need to know which configuration file has to be changed.
ISDN connectivity can be done with the usage of RemoteCAPI ISDN controllers.
