What NIS2 is and who it applies to
The European NIS2 Directive was transposed in Italy by Legislative Decree 138/2024. It generally applies to medium-sized and large companies carrying out specific activities identified by the decree, in sectors such as energy, transport, healthcare, water, digital infrastructure, managed ICT services for other businesses, postal services, waste management, chemicals, food, manufacturing and digital services. Some entities are covered regardless of size; otherwise, size must be assessed under the decree's criteria, taking into account headcount, financial data and links with other companies.
Entities are classed as essential or important, with proportionate measures and different supervisory regimes. Suppliers that are not directly in scope may also receive security requests, questionnaires and contractual requirements from their customers.
