NIS2 Directive

(101) This Directive lays down a multiple-stage approach to the reporting of significant incidents in order to strike the right balance between, on the one hand, swift reporting that helps mitigate the potential spread of significant incidents and allows essential and important entities to seek assistance, and, on the other, in-depth reporting that draws valuable lessons from individual incidents and improves over time the cyber resilience of individual entities and entire sectors. In that regard, this Directive should include the reporting of incidents that, based on an initial assessment carried out by the entity concerned, could cause severe operational disruption of the services or financial loss for that entity or affect other natural or legal persons by causing considerable material or non-material damage. Such initial assessment should take into account, inter alia, the affected network and information systems, in particular their importance in the provision of the entity’s services, the severity and technical characteristics of a cyber threat and any underlying vulnerabilities that are being exploited as well as the entity’s experience with similar incidents. Indicators such as the extent to which the functioning of the service is affected, the duration of an incident or the number of affected recipients of services could play an important role in identifying whether the operational disruption of the service is severe.
