The EU-CyCLONe network, or the European Cyber Crises Liaison Organisation Network, was established to support the coordinated management of large-scale cybersecurity incidents and crises at an operational level. The network facilitates the timely exchange of relevant information between EU Member States and European institutions. It is one of the tools provided for by the NIS2 Directive to strengthen the collective response to cyber crises at the European level.

Here is a detailed description of its purpose based on the sources:

• EU-CyCLONe is designed to enhance preparedness in managing large-scale incidents and crises.
• The network helps develop a shared situational awareness regarding large-scale cybersecurity events.
• EU-CyCLONe assesses the impact and consequences of large-scale cybersecurity incidents and crises and proposes potential mitigation measures.
• The network coordinates the management of such large-scale incidents and crises and assists in political decision-making regarding these events.

The sources also indicate that EU-CyCLONe:

• Will report regularly to the NIS Cooperation Group on the management of large-scale cybersecurity incidents and crises, including trends and impacts on essential and important entities.
• Will cooperate with the CSIRT network based on agreed-upon procedures.
• Will submit an assessment report on its operations to the European Parliament and the Council.

For organizations subject to the NIS2 Directive, understanding the role of EU-CyCLONe is an integral part of a structured NIS2 compliance path. The full text of the directive can be consulted in the official NIS2 Directive document.
