Cyber security: from compliance challenge to competitive advantage

The growing digitisation and connectivity of machines creates new opportunities for efficiency, flexibility and innovation. At the same time, it increases exposure to cyber threats that can lead to production downtime, data loss, reputational damage and even risks to physical safety.

As a result, cyber security is becoming a major focus for machine builders. Regulations such as the Cyber Resilience Act (CRA), the Machinery Regulation and RED-DA require manufacturers to address cyber security in a systematic and verifiable way throughout the entire machine lifecycle - from development and commissioning to operation and decommissioning.

Meeting these requirements is about more than compliance alone. A structured cyber security strategy can help machine builders minimise liability risks, protect their reputation, maintain access to international markets and strengthen their competitive position.

A risk-based approach to cyber security

A key element of the CRA is its risk-based approach. Manufacturers are expected to identify and assess threats and vulnerabilities and implement appropriate countermeasures. This requires regular risk analyses and the development of security concepts tailored to the specific application.

The goal is to protect machines against data loss, know-how theft, tampering and unplanned downtime while avoiding costly incidents. Technical safeguards such as access controls, encrypted communication and regular updates form the foundation of this approach. Audit logs can be used to detect tampering, encryption helps protect confidential information and access controls reduce the risk of unauthorised intervention.

Managing vulnerabilities throughout the machine lifecycle

Cyber security responsibilities do not end when a machine is delivered. New regulations place increasing emphasis on vulnerability management. From September 2026, actively exploited vulnerabilities must be reported under the CRA framework, while structured vulnerability management will become mandatory throughout the support period of a product from December 2027 onwards.

To support customers in meeting these requirements, Lenze has established a Product Security Incident Response Team (PSIRT) that identifies, assesses and communicates vulnerabilities. The company also uses Software Bills of Materials (SBOMs), providing transparency into software components and dependencies to help track vulnerabilities more efficiently and support compliance efforts.

Supporting machine builders on their cyber security journey

Cyber security is also embedded within Lenze's own development processes. Since 2025, the company has been certified by TUV Rheinland according to IEC 62443-4-1, confirming that cyber security is integrated into the entire product lifecycle, from design through maintenance. For machine builders, this provides access to products and expertise aligned with internationally recognised security requirements.

Beyond technology, employee competence and collaboration play an important role. Regular training, clear processes and open communication between machine builders, suppliers and operators are essential for addressing security requirements effectively and responding quickly to potential threats.

The conclusion is clear: cyber security is no longer solely an IT topic. It has become a key factor in machine development, operational reliability and long-term competitiveness. Companies that invest in cyber security today are not only preparing for future regulatory requirements but also creating a stronger foundation for sustainable business success.
