The German IT Security Act and the KRITIS regulation of the German Federal Office for Information Security (BSI), which went into effect in early May 2016, impose entirely new requirements on the operators of critical infrastructures, which includes waterworks above a certain size. Hence, the Kreiswerke Grevenbroich needed a comprehensive security assessment to develop a security concept.

Due to the specific requirements in industrial environments, Kreiswerke Grevenbroich decided to hire Siemens to inspect the existing and new systems as part of an Industrial Security Assessment pursuant to ISO 27001 which is based on the leading standard for information security management systems.

Kreiswerke Grevenbroich GmbH supplies drinking water to more than 200,000 people in the Rhein-Neuss District. For many years the company has been operating three in-house waterworks in the nearby region and also purchases water from a partner.
