Overview

Areas of application for SCALANCE S
The SCALANCE S Industrial Security Appliance devices protect nodes connected to the
protected network with a combination of different security measures. SCALANCE S devices
have different protective functions and individual devices or even entire automation cells can
be integrated into the protected area. The security modules can be operated not only in
bridge mode but also in router mode. This means that the security modules are used directly
at IP subnet boundaries. There are different product variants to meet specific requirements
such as the use of FO cables. For secure remote access via Internet, suitable devices of the
SCALANCE M-800 series are available.
SCALANCE S is optimized for use in an automation or industrial environment. It meets the
specific requirements of automation engineering, for example easy upgrading of existing
systems, simple installation and minimum downtimes if a fault occurs.
Advantages of the cell protection concept:
● Protection from data espionage and data manipulation
● Protection against overload of the communications system
● Protection from external influences
● Protection from addressing errors
● Secure remote access via Internet
● Problem-free integration into existing networks without reconfiguration of end nodes or
setup of new IP subnetworks
