Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, solutions, machines, equipment and/or networks. They are
important components in a holistic industrial security concept. The products and solutions
from Siemens undergo continuous development with this factor in mind. Siemens strongly
recommends that you regularly check for product updates.
For the safe operation of products and solutions from Siemens, it is necessary to take
suitable protective measures (e.g. cell protection concept) and to integrate each component
into an overall IT security concept which corresponds to state-of-the-art IT technology. Third-
party products that may be in use should also be considered. For more information about
