2.1 Security notes2.1 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 ne-
cessary to implement (and continually maintain) a holistic industrial security concept that cor-
responds 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, ma-
chines and networks. These systems, machines and components shall be connected to the
company network or the Internet only when and to the extent that this is absolutely neces-
sary and appropriate protective measures (e.g. firewalls and/or network segmentation) shall
be taken.
You can find further information about possible protection measures as part of Industrial Se-
curity in the following international series of standards, for example: IEC62443 "Network and
system security".
Flender products and solutions undergo continuous development in order to make them
even safer. Flender strongly recommends that you regularly implement product updates as
soon as they become 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.
