|security information|

|security information|Siemens provides products and solutions with industrial cybersecurity 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 cybersecurity 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|
|cybersecurity measures that may be implemented, please visit|
|www.siemens.com/cybersecurity-industry. 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|
|customer’s exposure to cyber threats. To stay informed about product updates,|
