It is Monday, 9:07 a.m. A message from your national cybersecurity authority reaches your CISO: please provide evidence of the cybersecurity risk-management measures you have implemented. Do you have an answer ready, or does a week of panic begin?
By mid-October 2026, 24 of the 27 EU Member States have transposed NIS2 into national law, according to the ECSO NIS2 tracker, so supervisors increasingly have the legal power to ask. This guide explains what a NIS2 evidence pack is, what belongs in it, and how to build one in 30 days.
Why 2026 Is the Year to Become Audit-Ready
Directive (EU) 2022/2555, known as NIS2, had to be transposed by 17 October 2024. Most Member States missed that date, but 2026 closed much of the gap. Germany's law has applied since December 2025, the Netherlands' Cyberbeveiligingswet took effect on 15 August 2026 (see our NIS2 compliance support in the Netherlands), and Austria's NISG 2026 followed on 1 October 2026. France, Ireland and Spain still lacked a national law in recent trackers, so check your own Member State's status. Even so, group-wide customers and supply-chain contracts rarely wait for local legislation. Operating there? Review our pages on NIS2 in France and NIS2 in Ireland.
Under Article 32, authorities can run on-site inspections, security audits and scans, and request evidence that your policies are genuinely implemented. Essential entities face proactive supervision; important entities face reactive supervision after an incident or complaint. The Article 21 duties are the same for both.
The stakes are real. Member States must set maximum fines of at least €10 million or 2% of worldwide annual turnover (whichever is higher) for essential entities, and at least €7 million or 1.4% for important entities. Article 20 also makes management bodies answerable for approving and overseeing the measures, and authorities can temporarily bar individuals from management roles in essential entities.
What Is a NIS2 Evidence Pack?
A NIS2 evidence pack is one indexed, version-controlled set of records that proves, control by control, that your obligations are met and working. It is the answer to every question a regulator might ask, stored so your team can produce it in hours, not weeks.
The NIS2 Compliance Checklist: 8 Things Your Evidence Pack Needs
| Evidence area | Reference | What to show |
|---|---|---|
| 1. Scope and classification | Art. 3 | Documented reasoning for essential or important status, relevant sectors, Member States of operation, and registration confirmations. |
| 2. Governance | Art. 20 | Board minutes approving measures, a named accountable owner, management training records. |
| 3. Risk and policies | Art. 21(2)(a) | Current risk assessment, information security policy, asset inventory. |
| 4. Incident handling | Art. 21(2)(b), Art. 23 | Response plan, "significant incident" criteria, 24-hour, 72-hour and one-month report templates, tabletop results, incident log. |
| 5. Business continuity | Art. 21(2)(c) | Backup policy, restore-test results, crisis management plan. |
| 6. Supply chain security | Art. 21(2)(d) | Supplier inventory, risk tiering, contract security clauses, assessments. |
| 7. Vulnerability handling and testing | Art. 21(2)(e)–(f) | Scan and penetration test reports, patch timelines, disclosure policy, internal audit. |
| 8. Cyber hygiene | Art. 21(2)(g)–(j) | Awareness training logs, cryptography policy, access reviews, MFA coverage. |
Give every item an owner, date, version and review cycle. For evidence rows 7 and 8, independent penetration testing and a vulnerability assessment produce exactly the dated proof supervisors like to see.
Show That It Works, Not Just That It Exists
Policies earn half the marks. Supervisors want operating evidence: approvals, test results, tickets and logs showing controls ran during the period. Article 21 requires measures that are appropriate and proportionate, so record your reasoning (size, sector, exposure) beside each decision.
An ISO 27001 programme is a strong foundation, but certification alone does not prove NIS2 compliance, so map each control to the Article 21 measures. Financial entities should also align with DORA, the sector-specific regime for ICT risk and incident reporting, while one incident can also start the GDPR 72-hour clock. Cut duplicated effort with our guide to NIS2 and GDPR compliance, or run frameworks together through Audit Fusion 360. Board members who need a clear briefing can use CISO advisory services.
Three Evidence Mistakes That Slow Audits Down
First, stale documents: a policy last reviewed in 2023 signals that nobody owns it. Second, scattered proof: evidence spread across inboxes and personal drives cannot be produced quickly. Third, untested plans: an incident procedure nobody has rehearsed will not survive a 24-hour deadline. Fix these three and most supervisory requests become routine.
Watch the Horizon: NIS2 Is Being Amended
On 20 January 2026, the European Commission proposed targeted amendments to NIS2 alongside a revised Cybersecurity Act, building on the Digital Omnibus package of 19 November 2025, which aims to simplify incident reporting. These proposals are still moving through the legislative process, so today's obligations apply in full. Build your pack in modular form so it can adapt.
Build Your Pack in 30 Days
- Week 1: confirm scope, entity type and national authority; run a gap analysis against Article 21.
- Week 2: close governance and incident-response gaps; collect board approvals.
- Week 3: test, running a tabletop exercise, a backup restore and a vulnerability scan.
- Week 4: assemble the index, then run a mock regulator request and time your response.
NIS2 Evidence Pack FAQ
Who needs a NIS2 evidence pack? Every in-scope essential and important entity, because supervisors can request proof of Article 21 measures.
Does NIS2 apply outside the EU? It can, when you provide in-scope services within the EU. Check Member State rules and your regulatory exposure. German-speaking teams can also download the NIS2 Readiness Guide für deutsche Unternehmen.
Ready before they ask? Our assessors can scope your obligations, close gaps and prepare an audit-ready file through NIS2 compliance consulting and audit. Book a free consultation.
