Is your FACTS installation ready to tackle the security challenges of digitalization?

Digitalization changes our energy systems. It offers great prospects and new business opportunities, but also harbors challenges in terms of cyber security. Cyber threats that endanger a stable operation can include attacks on communication between FACTS devices, on time- and synchronization-based control algorithms, and malicious sending of incorrect operational data. All these attacks can and should be prevented in advance. Even without a direct Internet connection, manipulated IT devices and the engineers’ and maintainers’ laptop also pose risks. To protect FACTS, we offer comprehensive cyber security support and services based on an in-depth defense concept. We identify your technical vulnerabilities, recommend appropriate security measures, and carry out their implementation. Our services for cyber security include:

  1. Consulting regarding e.g. requirements, evaluating the own status quo and recommending the resulting security measures
  2. Patch management (three service levels)
  3. Security reviews, penetration tests and incident handling.

Cyber Security Services for FACTS you can count on

Cyber threats are increasing with serious consequences for companies and communities worldwide. Critical infrastructure, such as power transmission systems, is increasingly becoming the main focus.


Today, IT systems are the foundation of critical processes for most companies. This leads to significantly increased risks of being attacked by hackers or viruses, and patching software weaknesses is not a onetime task but an ongoing endeavor throughout the system’s lifetime. For these reasons, Siemens Energy has developed a comprehensive cyber security service portfolio for FACTS to support you.
