NIS2 Directive: The Complete Guide (2026)

A person reading a large open book held in both hands, with a shield and checkmark on the cover (illustration)

NIS2 is no longer something to prepare for. In the Netherlands the directive became enforceable national law on 15 August 2026, when the Cyberbeveiligingswet (Cbw) entered into force without a transition period. Around 8,000 Dutch organizations now have to register, manage their cyber risks, train their management and report serious incidents.

The NIS2 directive (also referred to as NIS-2 or NIS 2.0) requires organizations across 18 sectors to implement robust cyber security measures, including security awareness training for all employees.

What NIS2 demands in practice, and how the Cyberbeveiligingswet translates it into Dutch obligations, is still hard to pin down. The law works in three layers, supervision is spread across sectors, and the European Commission is already working on amendments.

In this guide, we break down everything you need to know: what NIS2 is, who it applies to, the complete NIS2 checklist for 2026, and how to make your organization audit-ready.

What is the NIS2 directive?

The NIS2 directive (Directive (EU) 2022/2555) is the European Union’s updated framework for network and information security. It replaced the original NIS directive (NIS1) from 2016, which was the EU’s first piece of cybersecurity legislation.

NIS2 entered into force on 16 January 2023, and EU member states were required to transpose it into national law by 17 October 2024. However, most member states, including the Netherlands, missed this deadline.

The directive aims to achieve a high common level of cyber security across the EU by requiring organizations in critical sectors to:

  • Implement risk-based cyber security measures
  • Report significant incidents to authorities within strict timelines
  • Ensure management bodies are trained and accountable
  • Provide regular awareness training to all employees
  • Manage supply chain security risks

An estimated 160,000 entities across the EU fall under NIS2’s scope. That’s a tenfold increase compared to NIS1.

NIS2 starts with your people

Attackers target people before they target systems. That is why NIS2 expects regular security awareness training for every employee, management included. Guardey turns that into short weekly challenges and keeps the evidence ready for your supervisor.

NIS2 vs NIS1: what changed?

The original NIS directive was a solid starting point, but it had significant gaps. NIS2 addresses these across the board. Here’s a quick summary of the most important changes:

Aspect NIS1 NIS2
Sectors covered 7 sectors 18 sectors
Entities in scope ~15,000 ~160,000
Incident reporting No specific timeline 24h / 72h / 1 month
Penalties Determined per member state Up to €10M or 2% of turnover
Management liability Not addressed Personal liability for gross negligence
Supply chain Not explicitly required Mandatory risk management
Management training Not required Mandatory for board and C-suite

NIS2 legislation in Europe

NIS2 is an EU directive, which means it doesn’t apply directly to organizations. Each member state must transpose it into national law. Here’s where things stand in 2026.

Implementation status across the EU

Implementation progress varies significantly. Countries like Belgium, Croatia, and Italy were among the first to adopt national legislation. Others, including the Netherlands and Germany, took longer.

The European Commission opened infringement proceedings against 23 member states for missing the October 2024 transposition deadline, and sent reasoned opinions to 19 of them in May 2025. By May 2026, 22 of the 27 member states had adopted transposing legislation. The stragglers felt the pressure: on 8 July 2026 the Commission referred the Netherlands and Spain to the Court of Justice of the EU for failing to notify complete transposition. The Dutch law took effect five weeks later.

The January 2026 EU cybersecurity package

On 20 January 2026, the European Commission published a proposal to amend the NIS2 directive as part of a broader cybersecurity package. The key changes include:

  • Simplified jurisdictional rules for organizations operating across multiple EU countries
  • Certification-based compliance pathways, allowing organizations to demonstrate compliance through recognized certifications
  • Enhanced ransomware reporting with more detailed incident data requirements
  • Expanded scope to include providers of European Digital Identity Wallets and submarine data infrastructure
  • Reclassification of roughly 22,500 entities to lower the compliance burden for smaller organizations
  • A strengthened role for ENISA in coordinating cross-border supervision

The proposal builds on the Digital Omnibus package of November 2025, which already streamlined incident reporting and clarified how NIS2 relates to DORA and the CER directive. It now follows the ordinary legislative procedure, with negotiations in the European Parliament and the Council running through 2026 and a transposition period once it is adopted. Until then, nothing changes about the obligations you have today.

NIS2 in the Netherlands: the Cyberbeveiligingswet (Cwb)

In the Netherlands, the NIS2 directive is being transposed into the Cyberbeveiligingswet (Cwb). This law replaces the current Wbni (Wet beveiliging netwerk- en informatiesystemen).

A person stamping a document with a wax seal, a small Dutch flag on the desk (illustration)

Current status (March 2026)

  • The Tweede Kamer passed the bill on 15 April 2026, the Eerste Kamer followed on 7 July 2026
  • The Cyberbeveiligingswet entered into force on 15 August 2026, together with the Wet weerbaarheid kritieke entiteiten (Wwke)
  • There is no transition period: every obligation, registration included, applies from day one
  • Around 8,000 organizations fall under the Cbw, and roughly 500 more under the Wwke
  • The Cbw replaces the Wbni, so organizations that already reported under the old law are now held to the wider NIS2 requirements

Three regulatory components

The Dutch implementation consists of three layers:

  1. The Cyberbeveiligingswet, which is the primary law implementing NIS2
  2. The Cyberbeveiligingsbesluit (AMvB), a General Administrative Order defining specific obligations
  3. Sector-specific ministerial regulations with tailored requirements per sector

If your organization is in scope, the question is no longer whether to act but what to do first. These five steps cover the obligations that started immediately.

  1. Confirm whether you are in scope. Check your sector and size against the criteria below. You determine this yourself, nobody sends you a letter telling you that you are covered.
  2. Register your organization. Registration in the national entity register runs through the NCSC, at mijn.ncsc.nl. It has been mandatory since 15 August 2026 and organizations are responsible for registering on time themselves.
  3. Get your management trained. Board members have to follow cyber security training and can be held personally liable. Our NIS2 training for executives covers exactly this requirement.
  4. Set up your incident reporting process. Decide now who reports what and to whom, because the clock is short: an early warning within 24 hours, a full notification within 72 hours and a final report within one month.
  5. Start recurring awareness training. The duty of care covers your people as much as your systems. Short, repeated security awareness training with documented results is what turns a requirement into evidence.

Supervisory authorities have signalled that they will use the first year mainly to get to know the newly regulated sectors, through questionnaires and introductory meetings. A gentle start to supervision is not the same as a later start to the obligations, and organizations that can show a systematic approach will come out of that first conversation in far better shape.

Key Dutch obligations

Organizations falling under the Cyberbeveiligingswet must comply with four core obligations:

Obligation What it means NIS2 basis
Zorgplicht (duty of care) Implement appropriate technical and organizational measures to manage cyber security risks Article 21
Registratieplicht (registration duty) Register your organization in the national entity register through the NCSC, at mijn.ncsc.nl Article 3 and Article 27
Trainingsplicht voor bestuurders (management training obligation) Board members and management must undergo cyber security training Article 20(2)
Meldplicht (incident reporting obligation) Report significant incidents to the NCSC within the prescribed timelines: an early warning within 24 hours, a notification within 72 hours and a final report within one month Article 23

Supervisory authorities

Registration, incident reporting and enforcement are handled by different organizations:

Task Who handles it
Entity register The NCSC (Nationaal Cyber Security Centrum)
Incident reporting The NCSC as the main incident response team, alongside sector-specific CSIRTs for some sectors
Supervision and enforcement Sector-specific supervisory authorities, designated through ministerial regulations, check whether organizations actually meet their obligations

For organizations in the healthcare sector, the regulatory landscape is particularly complex, combining NIS2 requirements with existing healthcare-specific regulations around patient data protection.

Who does NIS2 apply to?

NIS2 applies to organizations based on two criteria: sector and size.

The directive distinguishes two categories of entities, each with its own sectors, supervision and fines:

Aspect Essential entities (highly critical sectors) Important entities (other critical sectors)
Sectors
  • Energy (electricity, oil, gas, hydrogen, district heating)
  • Transport (air, rail, water, road)
  • Banking and financial market infrastructures
  • Healthcare (hospitals, laboratories, medical device manufacturers, pharmacies)
  • Drinking water and wastewater
  • Digital infrastructure (DNS, TLD registries, cloud providers, data centers, CDNs)
  • ICT service management (managed service providers, managed security service providers)
  • Public administration
  • Space
  • Postal and courier services
  • Waste management
  • Manufacturing (medical devices, electronics, machinery, motor vehicles)
  • Food production, processing, and distribution
  • Chemical production and distribution
  • Digital providers (online marketplaces, search engines, social networking platforms)
  • Research organizations
Supervision Proactive supervision: regular audits and inspections Reactive supervision: investigations only after incidents or reports of non-compliance
Maximum fine Up to €10 million or 2% of global annual turnover Up to €7 million or 1.4% of global annual turnover

Size thresholds

Organizations in these sectors are in scope if they meet the following size criteria:

  • Medium enterprises: 50+ employees or €10 million+ annual turnover
  • Large enterprises: 250+ employees or €50 million+ annual turnover

Some entities are in scope regardless of size, including DNS providers, TLD registries, and (under the proposed 2026 amendments) providers of European Digital Identity Wallets.

NIS2 checklist (2026)

Use this comprehensive checklist to verify your organization meets all NIS2 requirements. This goes beyond just awareness training and covers the full spectrum of NIS2 obligations to help you prepare for compliance and audits.

NIS2 certification

A common question: is there an official NIS2 certification? The short answer is no, not yet.

Unlike ISO 27001, which has a well-established certification process, NIS2 is a legal requirement enforced through national supervisory authorities. There is no single “NIS2 certified” badge you can obtain.

However, there are important developments.

Certification-based compliance (proposed in 2026)

The European Commission’s January 2026 cybersecurity package proposes certification-based compliance pathways. This means organizations holding certain recognized certifications may be able to demonstrate NIS2 compliance, or at least partial compliance, through these certifications.

ISO 27001 as a foundation

ISO 27001 is widely recognized as the closest existing standard to NIS2 requirements. Organizations with ISO 27001 certification will find that many NIS2 requirements are already covered. However, NIS2 has additional requirements that go beyond ISO 27001, including:

  • Specific incident reporting timelines (24h, 72h, 1 month)
  • Management liability and mandatory board-level training
  • Supply chain security assessments
  • Sector-specific requirements

NIS2 quality marks and readiness assessments

Several third-party organizations offer NIS2 readiness assessments, maturity scans, or quality marks. While these are not official certifications, they can help organizations benchmark their compliance and demonstrate their commitment to stakeholders.

NIS2 and security awareness training

Security awareness training is one of the most explicit requirements in the NIS2 directive. Article 20 states that management bodies must undergo training and that organizations should offer similar training to their employees on a regular basis.

Three colleagues each looking at a smartphone with a shield on the screen, a stopwatch showing three minutes above them (illustration)

Why NIS2 emphasizes awareness training

The numbers make it clear. According to the ENISA Threat Landscape 2025 report:

  • Phishing accounts for 60% of all intrusion access points
  • Over 80% of social engineering attacks now leverage AI-generated content
  • 53.7% of cyber incidents targeted organizations classified as essential entities under NIS2
  • Public administration alone accounted for 38.2% of targeted attacks

The human factor remains the number one vulnerability. Without trained employees who can recognize and report threats, even the most sophisticated technical defenses can be bypassed.

What NIS2 expects from your awareness training program

Expectation What it means
Regular training, not once a year Ongoing, regular training is expected.
Management participation Board members and C-suite must participate.
Relevance Training must cover current and emerging threats, including AI-powered attacks.
Evidence You must be able to demonstrate that training is taking place and is effective.
Coverage All employees with access to systems and data, including contractors.

Common mistakes in NIS2 compliance

Many organizations underestimate the effort required for NIS2 compliance. Here are the pitfalls we see most often.

Mistake Why it goes wrong What to do instead
Treating the first year as a grace period The Cyberbeveiligingswet entered into force on 15 August 2026 without a transition period. Supervisors starting gently is not the same as obligations starting later. Register and document now. Organizations that wait for a first inspection end up doing months of work under time pressure, with a supervisor already watching.
Treating NIS2 as an IT-only problem NIS2 explicitly requires management accountability. This is not something you can delegate entirely to your IT department. Make sure board members are trained, approve the cybersecurity measures and know they can be held personally liable.
Ignoring supply chain requirements Many organizations focus on their own security but overlook their suppliers. Assess and manage the cybersecurity risks in your entire supply chain, as NIS2 requires.
Annual awareness training only A single yearly training session does not meet the “regular” training requirement. Show the ongoing engagement auditors expect: monthly micro-learnings, regular phishing simulations, and continuous measurement.
Not knowing whether NIS2 applies to you Surprisingly, many organizations haven’t even assessed whether they fall under NIS2’s scope. Don’t assume you’re excluded. Check the sector and size criteria carefully.
No incident response testing Having an incident response plan on paper is not enough. NIS2 expects you to test it. Conduct tabletop exercises, simulate incidents, and ensure your team can meet the 24-hour early warning deadline.
Missing the registration requirement Nobody registers your organization for you and no letter arrives to remind you, which makes it the easiest obligation of all to miss. Register your organization yourself in the entity register at the NCSC, through mijn.ncsc.nl, as the Cyberbeveiligingswet requires.

NIS2 vs ISO 27001 vs DORA: how do they compare?

Many organizations need to comply with multiple frameworks. Here’s how NIS2 compares to ISO 27001 and DORA (Digital Operational Resilience Act).

Requirement NIS2 ISO 27001 DORA
Type EU Directive (legal requirement) International standard (voluntary) EU Regulation (legal requirement)
Scope 18 sectors, essential and important entities Any organization (by choice) Financial sector only
Awareness training mandatory? Yes (Article 20) Yes (Clause 7.3, A.6.3) Yes (Article 13)
Management training required? Yes (mandatory, board-level) Required (clause 5.1) Yes (mandatory, board-level)
Incident reporting timeline 24h / 72h / 1 month Not specified (define your own) 4h / 72h (major ICT incidents)
Supply chain security Mandatory A.5.19-A.5.22 (supplier controls) Mandatory (ICT third-party risk)
Penalties Up to €10M or 2% of turnover Loss of certification Up to €10M or 2% of turnover
Certification available? Not yet (proposed in 2026) Yes (accredited certification bodies) Not yet
Personal liability for management? Yes No Yes

The good news: organizations with ISO 27001 certification have a strong head start on NIS2 compliance. The risk management approach, documentation requirements, and awareness training obligations overlap significantly.

Frequently asked questions about the NIS2 directive

What does NIS2 stand for?

NIS2 stands for the Network and Information Security Directive 2. It is also commonly written as NIS-2 or NIS 2.0. It is the second version of the EU’s cybersecurity directive, replacing the original NIS directive from 2016.

When does NIS2 come into force in the Netherlands?

It already has. The Cyberbeveiligingswet entered into force on 15 August 2026, after the Tweede Kamer passed the bill on 15 April 2026 and the Eerste Kamer on 7 July 2026. There is no transition period, so the duty of care, the registration duty, management training and incident reporting all apply right now.

Is security awareness training mandatory under NIS2?

Yes. Article 20 of the NIS2 directive explicitly requires management bodies to undergo cybersecurity training and to offer similar training to employees on a regular basis. This makes awareness training a legal obligation, not optional.

Does NIS2 apply to SMEs?

It can. Organizations with 50 or more employees or €10 million or more in annual turnover operating in one of the 18 covered sectors are in scope. Some entities are included regardless of size (e.g., DNS providers, TLD registries).

What are the penalties for NIS2 non-compliance?

Essential entities face fines of up to €10 million or 2% of global annual turnover. Important entities face up to €7 million or 1.4% of global turnover. Additionally, management can be held personally liable.

Can I get NIS2 certified?

Not currently. There is no official NIS2 certification. However, the European Commission’s 2026 cybersecurity package proposes certification-based compliance pathways. ISO 27001 certification covers many NIS2 requirements and is recognized by auditors as a strong foundation.

How is NIS2 different from GDPR?

GDPR focuses on protecting personal data. NIS2 focuses on the security of network and information systems more broadly. They are complementary: NIS2 measures help protect the systems that process personal data, supporting GDPR compliance as well.

What is the relationship between NIS2 and the Cyberbeveiligingswet?

The Cyberbeveiligingswet is the Dutch national law that implements the EU NIS2 directive. It translates the directive’s requirements into enforceable Dutch legislation and replaced the previous Wbni (Wet beveiliging netwerk- en informatiesystemen) on 15 August 2026. Put simply: NIS2 says what Europe wants, the Cbw says what you can be held to in the Netherlands, and it is the Cbw that a Dutch supervisor will hold you to.

What to do now that the NIS2 applies

NIS2 stopped being a future concern on 15 August 2026. Registration, the duty of care, management training and incident reporting apply today, and supervisors will start asking about them within the year. The organizations that come out of that first conversation well are the ones that can show what they do, not the ones that can explain what they intended.

With Guardey Security Awareness Training, your employees receive 3-minute weekly micro-learnings covering phishing, data handling, incident reporting, and more. All aligned with NIS2 requirements, with full reporting for compliance audits.
