The relevance of the reasearch topic stems from the fact that different state bodies are involved in addressing cybersecurity services. While each of the state bodies has their own goals and objectives, the successful resolution of the issues entirely depends on their effective cooperation. The existing resources and expertise available in the EU member states and corresponding EU institutions, bodies and agencies provide a solid basis for a collective response to cybersecurity threats. As a result, the EU has established a system of cyber security risk management bodies. The purpose of this article is to investigate the activities of key EU cyber security authorities. To achieve this goal and analyse the activities of the main EU bodies in the field of cybersecurity , the author has used several methods, such as the systematic approach, the formal-legal method, the comparative-legal method and the historical method. The author has come to the conclusion that cooperation and information exchange are essential elements in addressing cyber security issues. At the same time, to achieve coherence among cyber security bodies, the EU is taking measures to strengthen their joint work. In addition, it has been concluded that the EU, as a regional integration organization where member states act on the basis of mutual trust, is a reliable platform for addressing cyber security issues.
