Comparison

NIS2 vs ISO 27001 — statutory measures or certification?

NIS2 guide ISO 27001 guide

Published Reviewed

NIS2 sets public-law duties for covered entities; ISO 27001 defines a management system an organisation may certify.

Side by side

Dimension NIS2 ISO 27001
Scope Legal entity, sector, size and national law. Chosen ISMS boundary and interested parties.
Leadership Management approval, oversight and training under law. Leadership commitments and assigned ISMS responsibilities.
Measures A statutory minimum set including continuity, supply chain, vulnerability handling and authentication. Risk-selected controls justified in the Statement of Applicability.
Failure Supervision, remediation, fines and possible management consequences. Nonconformities, corrective action and certificate status.

How they combine

A well-scoped ISO 27001 programme can carry much of the evidence, but it does not decide NIS2 scope, incident reporting, registration, or national supervisory duties.

A quick self-check

Are you ready?

  • Is the legal entity in NIS2 scope even if the certificate is narrower?
  • Are statutory measures mapped to owned controls?
  • Can 24-hour reporting work outside the audit cycle?
NIS2 The EU cybersecurity directive covering risk management, governance and incident reporting across critical sectors. ISO 27001 An international requirements standard for establishing and improving an information security management system.
