2.1 Security notes
Flender offers products and solutions with industrial security functions, which support the safe
and secure operation of plants, systems, machines and networks.
In order to safeguard plants, systems, machines and networks against cyber threats it is
necessary to implement (and continually maintain) a holistic industrial security concept that
corresponds to the current state of the art. Flender products and solutions undergo continuous
development in this respect.
Customers are responsible for preventing unauthorised access to their plants, systems,
machines and networks. Systems, machines and components shall only be connected to the
company network or the Internet when and as far as this is absolutely necessary and
appropriate protective measures (e.g. use of firewalls and network segmentation) shall be
taken.
In addition the recommendations of Siemens regarding appropriate protective measures shall
be observed. You can find further information about Industrial Security at:

Flender products and solutions undergo continuous development in order to make them even
safer. Flender strongly recommends that you regularly carry out any updates as soon as they
are available and that you only use the current product versions. Use of older or no longer
supported versions can increase the risk of cyber threats.
