With its security concept, Siemens offers a security solution specially designed for industrial automation engineering that satisfies the specific requirements of industrial communication. The concept uses the integrated Ethernet structures and protects the production areas and other sensitive areas within the company against the risks associated with Internet technology.

Siemens is the only global player in automation engineering that has all the expertise and products for IT security at its disposal: From the network infrastructure to the automation technology itself, Siemens is the only manufacturer in the world to offer all the necessary components.

SCALANCE S protects automation cells against unauthorized access and unnecessary communication load. Even in the event of interference in the external network, data traffic within the automation cell remains unaffected.

SCALANCE S modules protect communication independently of the application protocol used. All IP-based protocols and the still widely used Layer-2 protocols of automation engineering can be easily protected in this way without restricting permissible productive data traffic.
