Cybersecurity for power systems

Strengthen power system cybersecurity with solutions aligned to NIST CSF 2.0 and IEC 62443. Identify risks, protect assets, detect and respond to threats, and build long-term cyber resilience.

Cybersecurity challenges

The digital transformation of power systems is enabling faster and valuable outcomes but also new cybersecurity challenges. Operators must navigate evolving cyber threats, increasing regulatory requirements, limited visibility into OT environments, and aging infrastructure with varying security capabilities. At the same time, resource and skills shortages make it difficult to manage cyber risks effectively throughout the asset lifecycle.

To maintain reliable and resilient operations, power system operators need a comprehensive cybersecurity strategy that combines risk management, operational visibility, regulatory compliance, and continuous protection.
