NIS2 Directive

(97) The internal market is more reliant on the functioning of the internet than ever. The services of almost all essential and important entities are dependent on services provided over the internet. In order to ensure the smooth provision of services provided by essential and important entities, it is important that all providers of public electronic communications networks have appropriate cybersecurity risk-management measures in place and report significant incidents in relation thereto. Member States should ensure that the security of the public electronic communications networks is maintained and that their vital security interests are protected from sabotage and espionage. Since international connectivity enhances and accelerates the competitive digitalisation of the Union and its economy, incidents affecting undersea communications cables should be reported to the CSIRT or, where applicable, the competent authority. The national cybersecurity strategy should, where relevant, take into account the cybersecurity of undersea communications cables and include a mapping of potential cybersecurity risks and mitigation measures to secure the highest level of their protection.
