What technical measures does NIS2 require?
NIS2 Article 21 requires covered entities to implement risk-management measures including risk analysis and security policies, incident handling, business continuity and crisis management, supply chain security, secure acquisition and development with vulnerability handling, procedures to assess measure effectiveness, cyber hygiene and training, cryptography policies, access control and asset management, and multi-factor authentication. Hardened, continuously verified system configurations underpin several of these measures, which is where CIS benchmarks apply.
The longer answer.
NIS2 deliberately states outcomes rather than prescribing specific technical standards, so regulators and auditors look for recognized baselines as proof of "appropriate and proportionate" measures. CIS benchmarks are among the most widely referenced configuration baselines for demonstrating that systems handling essential services are hardened and stay hardened.
The measures with the strongest configuration component are access control, cryptography, secure system acquisition and maintenance, and effectiveness assessment. Continuous benchmark scanning with drift detection covers the effectiveness-assessment obligation directly: it is documented, repeatable proof that technical measures keep operating between audits.
