Product Information
Security information
Siemens provides products and solutions with industrial security functions that support the secure operation of plants,
systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and
continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens' products and solutions constitute one
element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems, machines and networks. Such
systems, machines and components should only be connected to an enterprise network or the internet if and to the extent
such a connection is necessary and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please visit
(https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more secure. Siemens strongly
recommends that product updates are applied as soon as they are available and that the latest product versions are used. Use
of product versions that are no longer supported, and failure to apply the latest updates may increase customers' exposure to
cyber threats.
