ENTSO-ENetwork Code on Cybersecurity
The Network Code on Cybersecurity (NCCS) aims to set a European standard for the cybersecurity of cross-border electricity flows. It includes rules on cyber risk assessment, common minimum requirements, cybersecurity certification of products and services, monitoring, reporting and crisis management.
This Network Code provides a clear definition of the roles and responsibilities of the different stakeholders for each activity.
To learn more about the different components of the Network Code on Cybersecurity, watch our video series:
Play a role in EU electricity cybersecurity: Join cybersecurity stakeholder committee
- identify problems and propose improvements to the implementation of the existing cybersecurity network code;
- recommend future revisions of the network code;
- identify whether any additional risk prevention rules may be needed for the electricity sector; and
- respond to technological developments in the sector.
By tackling these points, the cybersecurity committee will help maintain a high, common level of cyber resilience in Europe’s electricity grid and adapt policy to evolving digital risks. We invite industry associations that could offer a pan-European perspective on cybersecurity aspects of cross-border electricity flows to join.
Deadline to apply is 2 July 2025, with the first meeting planned for autumn 2025. See how to apply.
See the Terms of reference for the cybersecurity committee for electricity.

Frequently Asked Questions (FAQs)
Who are the “all concerned CSIRTs” in art 37.5? All CSIRTs in the Member States? Or all concerned CSIRTs in Europe?
All concerned CSIRTs means all CSIRTs in charge of high- and critical-impact Entities that could be impacted by the specific threat or could provide useful information to high- and critical-impact entities to actively prepare their defenses. The legislation doesn’t apply outside the EU, except if there is a specific agreement (see Art.14).
When should high- and critical-impact Entities start reporting cyber-attacks and sharing information linked (Art.38.3)?
During the transition period, high- and critical-impact entities can apply the NCCS on a voluntary basis. But following Art.38.4 they will need the Cyber-Attack Classification Scale Methodology (Art.37.8) to define if a cyber-attack is reportable or not. In addition, to determine the “potential impact” of a cyber-attack (Art.37.8.a), the methodology may need the result of the Union-Wide Risk Assessment. If a high- or critical-impact Entity reporting an incident through NIS2 estimates that the cross-border electricity flows could be impacted, it should alert its authority of the potential impact.
When should the competent authorities start sharing information related to cyber threats, to unpatched actively exploited vulnerability and to cyber-attacks?
As soon as competent authorities receive information from high- and critical-impact Entities, they should share it according to the NCCS, with full respect of national confidentiality requirements.
