The NIS Regulation refers to the EU’s Network and Information Security Directive, which sets minimum cybersecurity requirements for operators of essential services and digital service providers. Its aim is to improve the overall cybersecurity posture across critical sectors such as energy, transport, health, and digital infrastructure. The regulation requires organizations to implement appropriate security measures, report significant incidents, and cooperate with national authorities. By harmonizing standards across member states, the NIS Regulation helps ensure a high common level of network and information security throughout the European Union.
