The security modules of the SCALANCE S range can be used to protect all devices of an Ethernet network against unauthorized access. In addition, SCALANCE S612 or SCALANCE S623 also protect the data transmission between devices or network segments (e.g. automation cells) against data manipulation and espionage; they can also be used for secure remote access over the Internet.

The security modules can be operated not only in bridge mode but also in router mode, and can thus also be used direct at IP subnetwork borders.

Secure remote access over the Internet or GPRS/UMTS/LTE is possible with the SCALANCE M800 series GPRS/UMTS/LTE routers.

SCALANCE S is optimized for use in automation and industrial environments, and meets the specific requirements of automation systems, such as easy upgrades of existing systems, simple installation and minimal downtimes in the event of a fault.
