Endian 4i Edge Appliance is an appliance (desktop or rail-mounted) that provides secure access to SCADA equipment. This document is both an User Manual and a Guide to the configuration of the various part of the Endian 4i Edge Appliance’s web interface and its functionalities.

The latest updates and corrections to this manual, referred to the latest release of the Endian 4i Edge Appliance, will be available online at http://docs.endian.com/5.1/utm.

This reference manual is Copyright (c) 2011-2019, Endian S.r.l., Italy and corresponds to revision 4 of the online version.


Without the great work of the Smoothwall and then of the IPCop team, neither Endian 4i Edge Appliance nor this document would exist. Therefore we would like to thank them all for their hard work.

Thanks to Sourceforge for the hosting. Without Sourceforge we would not have the possibility to gain such a huge worldwide visibility. You are really helping us very much!
