At the national level
the missions of the HCPN can be divided into four groups:
- coordinating counter-terrorism measures;
- preventing and managing crises of any kind affecting the vital interests or essential needs of all or part of the country or population;
- protecting critical national and European infrastructures;
- contributing, together with the Government's Computer Emergency Response Team (GovCERT) and the National Agency for the Security of Information Systems (Agence nationale de la sécurité des systèmes d'information - ANSSI), to the definition and implementation of the national cyber-security strategy.
At the international level
the HCPN represents the country at European Union fora, NATO, Benelux and any other international organisation dealing with the management of crises and civilian emergency response plans.
With its neighbours
The HCPN is responsible for establishing and maintaining contact with the organisations in neighbouring countries that have similar or identical responsibilities to those of the HCPN.
