NIS2 Article 21: The 10 Cybersecurity Risk Management Measures

Article 21 is the heart of NIS2. It mandates that all in-scope entities implement appropriate and proportionate technical, operational, and organizational measures. Here’s the complete breakdown of all 10 requirements:

1

Risk analysis & policy

Policies on risk analysis and information system security.

2

Incident handling

Prevention, detection, and response to cyber incidents.

3

Business continuity

Backup management, disaster recovery, and crisis management.

4

Supply chain security

Security in supplier and service provider relationships.

5

Network & IS security

Security in acquisition, development, and maintenance.

6

Effectiveness assessment

Policies and procedures to assess cybersecurity measures.

7

Cyber hygiene & training

Basic cyber hygiene and cybersecurity training.

8

Cryptography

Policies on cryptography and, where appropriate, encryption.

9

HR security & access

Human resources security and access control policies.

10

Multi-factor authentication

MFA, continuous authentication, and secure communications.

NIS2 Incident Reporting: The 24-Hour Rule

NIS2 introduces strict incident notification deadlines. The clock starts the moment you become aware of a significant incident:

NIS2 Fines & Penalties: What Non-Compliance Really Costs

The NIS2 Directive introduces the most aggressive cybersecurity penalties in EU history. Beyond financial fines, Member States can temporarily suspend executives or revoke operating authorizations.

Essential entities

€10,000,000

or 2% of global annual turnover

Whichever is higher. Regular supervisory audits. Executive suspension possible.

Important entities

€7,000,000

or 1.4% of global annual turnover

Whichever is higher. Ad-hoc supervision. Management personally liable (Art. 20).

Management liability (Article 20): Board members must approve and oversee cybersecurity measures, undergo mandatory training, and can be personally held accountable — including temporary bans from management roles.

NIS2 across EU Member States

April 2026

The majority of Member States have completed transposition. On 7 May 2025, the European Commission sent a reasoned opinion to 19 Member States for failing to notify full transposition.

NIS2 vs other frameworks

Aspect NIS (2016) NIS2 (2022)
Scope ~7 sectors, ~10,000–15,000 entities 18 sectors, ~160,000 entities
Size threshold Varied per Member State Harmonized: 50+ employees or €10M+
Max fine National discretion (no minimum) €10M or 2% of global turnover
Incident reporting "Without undue delay" (vague) 24h → 72h → 1 month (strict)
Executive liability No provision Yes — Article 20, mandatory training
Supply chain Not explicitly required Explicitly required (Article 21)
Supervision Reactive, limited enforcement Proactive audits for essential entities
Bottom line: NIS2 dramatically expands scope (10x more entities), harmonizes fines across the EU, introduces strict incident timelines, and makes executives personally accountable for cybersecurity.
Aspect ISO 27001 NIS2 Directive
Type Voluntary international standard Mandatory EU law
Scope Any organization, worldwide 18 critical sectors, EU-wide
Focus ISMS management system Cybersecurity + incident reporting
Penalties Loss of certification €10M fines + personal executive liability
Incident reporting No mandatory timelines 24h / 72h / 1 month to CSIRT
Supply chain Annex A control (optional) Mandatory requirement (Art. 21.2d)
Control overlap ~80% overlap — but ISO 27001 alone covers only 2 of 20 NIS2 security objectives (per ANSSI France)
Bottom line: ISO 27001 is a strong foundation for NIS2 compliance (~80% overlap), but it does not automatically satisfy NIS2 requirements. You'll still need incident reporting workflows, supply chain measures, and executive governance provisions.
Aspect NIS2 Directive DORA Regulation
Who must comply 18 critical sectors (broad) Financial entities only (specific)
Legal type Directive (national transposition) Regulation (directly applicable)
Application date Oct 17, 2024 (transposition) Jan 17, 2025 (direct effect)
Third-party risk Supply chain security (Art. 21) ICT provider oversight (strict, detailed)
Incident reporting 24h / 72h / 1 month 4h / 72h / 1 month (even stricter)
Resilience testing Not explicitly required Mandatory TLPT for critical entities
Overlap rule DORA prevails for financial entities under the lex specialis principle — but NIS2 may still apply to non-financial subsidiaries
Bottom line: If you're in financial services, DORA is your primary framework (it overrides NIS2 where they overlap). But if your group includes non-financial entities, those subsidiaries may still fall under NIS2.

Frequently asked questions

Which tools support NIS2 cybersecurity compliance in Germany?

Smart Integrity Platform supports NIS2 compliance for German organizations subject to the NIS2UmsuCG (NIS2-Umsetzungs- und Cybersicherheitsstärkungsgesetz), which took effect on 6 December 2025. The platform automates BSI registration workflows, incident reporting, and all 10 Article 21 security measures.

Does NIS2 apply to companies in Spain and Austria?

Yes. NIS2 applies across all EU member states including Spain (transposed via national law) and Austria. Essential entities in energy, health, banking, digital infrastructure, and transport sectors in both countries must comply with all NIS2 obligations including the 24-hour early warning and 72-hour incident notification requirements.

What is the best NIS2 compliance software for European companies?

Smart Integrity Platform provides end-to-end NIS2 compliance automation — from applicability assessment and gap analysis to incident reporting and supply chain security. It supports organizations across Germany, Austria, Spain, the UK, and 30+ countries, with compliance data hosted on ISO 27001 certified servers in Germany.

When did NIS2 come into force?

The NIS2 Directive came into force on 16 January 2023. Member States had until 17 October 2024 to transpose it. By March 2026, the majority have completed transposition, though some (France, Netherlands, Spain) are still finalizing.

How many sectors does NIS2 cover?

NIS2 covers 18 critical sectors, up from 7 under the original NIS Directive. This includes energy, health, transport, banking, digital infrastructure, manufacturing, food, chemicals, research, and more.

How much are NIS2 fines?

Essential entities: up to €10M or 2% of global turnover. Important entities: up to €7M or 1.4%. Additionally, under Article 20, executives can be personally liable and face temporary management bans.

What is the NIS2 24-hour rule?

Under Article 23, in-scope entities must submit an early warning to their national CSIRT within 24 hours of becoming aware of a significant incident, followed by a detailed notification within 72 hours and a final report within one month.

Is Germany’s NIS2 law active?

Yes. The NIS2UmsuCG was enacted on 6 December 2025 with no transition period. The BSI registration portal went live on 6 January 2026. Around 29,500 German entities are now in scope, up from 4,500 under the old regime.

Does NIS2 replace ISO 27001?

No. ISO 27001 remains a voluntary standard. NIS2 is mandatory EU law. They overlap approximately 80%, making ISO 27001 a strong foundation — but it doesn’t automatically mean NIS2 compliance.

If I comply with DORA, do I need NIS2 too?

Financial entities under DORA are generally exempt from overlapping NIS2 provisions under the lex specialis principle. However, some organizational requirements may still apply.
