The law in brief

NIS2 is the EU's cybersecurity law for organizations that keep society and the economy running. It raises the bar on cybersecurity risk management, makes senior management accountable for it, and sets strict timelines for reporting significant incidents.

It is a directive, so it applies through each member state's national law. The obligations are broadly the same everywhere, but registration, supervision and details vary by country.

A quién se aplica

  • Essential and important entities in the sectors listed in Annexes I and II, including energy, transport, banking, health, drinking water, digital infrastructure, ICT service management, public administration, space, postal services, waste, chemicals, food, manufacturing of critical products, digital providers and research.
  • Generally medium and large organizations (50 or more employees, or more than €10 million annual turnover and balance sheet), with some covered regardless of size, such as DNS providers, top-level domain registries and qualified trust service providers.
  • It reaches organizations established outside the EU that provide covered services in the EU, which may need a representative.

What it requires

Management accountability

Management bodies must approve the cybersecurity risk-management measures, oversee their implementation and follow training, and can be held liable for infringements.

Cybersecurity risk-management measures

Take appropriate and proportionate technical, operational and organizational measures, covering at least risk analysis, incident handling, business continuity and crisis management, supply chain security, secure development, vulnerability handling, cyber hygiene and training, cryptography, access control and multi-factor authentication.

Report significant incidents in stages

Send the national authority or CSIRT an early warning within 24 hours of becoming aware of a significant incident, an incident notification within 72 hours, and a final report within one month.

Tell recipients of your services

Where a significant incident is likely to affect the service, inform its recipients without undue delay, including measures they can take themselves.

Enforcement and penalties

Los Estados miembros deben prever multas con un máximo de al menos €10 millones o el 2% del volumen de negocio anual mundial, lo que sea mayor, para las entidades esenciales, y de al menos €7 millones o el 1.4% para las entidades importantes (art. 34). Las autoridades también pueden ordenar auditorías, suspender certificaciones y, en el caso de las entidades esenciales, prohibir temporalmente a personas ejercer funciones de dirección (art. 32). Las entidades esenciales se supervisan de forma proactiva; las importantes, principalmente a posteriori.

What's changing

National laws still arriving. Member states had to transpose NIS2 by 17 October 2024, and several did so late. Your duties start under the law of the member state where you are established or provide services. Regulatory Watch reports national transposition and guidance.

What to do first

  1. Confirm whether you are in scope, by sector and size, in each country where you operate, and register where required.
  2. Brief and train your management body; it must approve and oversee cybersecurity risk measures.
  3. Gap-assess against the Article 21 measures, especially supply chain security, multi-factor authentication and incident handling.
  4. Set up 24-hour, 72-hour and one-month reporting for significant incidents.
  5. Review supplier contracts for security requirements and incident cooperation.
