A NIS2 readiness checklist for European mid-market businesses

The NIS2 directive extends the EU's cyber-security obligations to thousands of mid-market organisations that previously sat outside its scope. Whether you operate a manufacturing plant in Bavaria, a logistics hub in Rotterdam or a software house in Warsaw, the question is no longer whether NIS2 applies but how you demonstrate compliance before your competent authority asks.

1. Confirm your category

NIS2 distinguishes between "essential" and "important" entities. Mis-classifying yourself is the most common early error — it changes both your reporting deadlines and the magnitude of fines you face. Map your operating sectors against Annex I and Annex II of the directive before doing anything else.

2. Establish a board-level cyber-security mandate

The directive introduces personal liability for executives. Document who at board level owns cyber-security risk, capture this in your governance framework, and ensure your minutes show genuine oversight — not box-ticking.

3. Operate a risk-based cyber-security policy

NIS2 expects a written, board-approved policy that ties controls to measurable risks. Generic templates downloaded from the internet will not pass scrutiny.

4. Run a credible incident-management process

You will need to report significant incidents to your CSIRT within 24 hours of detection (early warning), 72 hours (notification) and one month (final report). Run table-top exercises now to ensure you can hit those windows under stress.

5. Address the supply chain

NIS2 makes you responsible for assessing the security of your direct suppliers and service providers. Move beyond the annual questionnaire — adopt continuous attestation.

6. Cover the basics that auditors verify first

Multi-factor authentication on all privileged and remote access

Patch management with documented SLA

Backup, restore and disaster-recovery testing within the last 12 months

Encryption of data in transit and at rest

Documented identity and access management lifecycle

7. Prepare your evidence room

Auditors do not assess what you say — they assess what you can prove. Build a single-source-of-truth repository of policies, risk assessments, training records, incident reports and asset inventories.

8. Test your detection and response capability

Penetration testing, red-team exercises and tabletop incident response are no longer optional. Schedule them, fund them, and act on the findings.

9. Train people, not just admins

The directive expects security awareness across the organisation. Targeted training for finance, HR and engineering is far more effective than generic e-learning.

10. Get continuous monitoring in place

A 24/7 SOC — whether in-house, hybrid or outsourced — is the difference between detecting an incident and explaining one to your regulator after the fact.

11. Document the residual risk

NIS2 does not demand zero risk. It demands that you understand and accept your residual risk consciously, with the right people informed.

12. Run a pre-audit dry run

Engage a third party — your assessor, your MDR provider, your consultant — to walk the full evidence trail two months before your real assessment.
