NIS2 penalties 2026: real cases and how to avoid them in IT projects

NIS2 penalties 2026 have stopped being a theoretical ghost. After effective transposition in most member states and the first cases opened in Germany, the Netherlands and Spain, fines for breaching the network and information systems security directive are already reaching seven-figure sums. If your organisation falls within the scope of NIS2 and has not closed the basic controls, 2026 is the year the risk materialises.

In my more than thirty years leading IT projects in banking, insurance and regulated sectors, I have seen how most organisations treat compliance as a last-minute formality. With NIS2, that approach no longer works: the directive shifts responsibility to the management body and requires documented evidence, not good intentions. In this article I explain what penalties the regulation sets out, what patterns the first cases share and how to organise a realistic plan to reduce your exposure before the audit.

What NIS2 penalties are and who they apply to

The NIS2 directive distinguishes two categories: essential entities and important entities. The former face fines of up to 10 million euros or 2% of annual global turnover, whichever is higher. The latter, up to 7 million or 1.4%. It applies to sectors such as energy, transport, banking, healthcare, water and relevant digital service providers.

It is worth understanding that the financial amount is only one part of the penalty regime. NIS2 empowers national authorities to impose binding corrective measures, to temporarily suspend certifications or authorisations and, in the most serious cases, to temporarily disqualify executives from performing management functions. That personal responsibility of the board is the deepest cultural change the regulation introduces: compliance stops being an exclusive matter for the technical department and becomes a fiduciary obligation of whoever leads the organisation.

Another important nuance is the expanded scope compared with the old NIS. The size threshold means that many medium-sized companies that were previously outside now fall within scope, often without knowing it. I have seen companies convinced they were not affected who, on reviewing their sector classification and turnover, discovered they were important entities with all the obligations that entails. The first exercise, before any technical control, is to confirm whether the organisation falls within scope and register with the competent authority.

If you need the full regulatory framework and its intersection with DORA and the EU AI Act, I break it down in IT regulations 2026.

Real cases setting the trend in 2026

Without going into details that are sub judice, the cases already known share a very clear pattern. Companies that suffered an incident, mishandled the notification to the national authority, had no documented prior risk analysis and could not demonstrate cybersecurity training of their management. The penalty does not come for the attack, it comes for the absence of evidence of compliance.

The detail that recurs most is late or incomplete notification. NIS2 sets an early warning within 24 hours, a more detailed notification within 72 hours and a subsequent final report. Several of the penalised organisations met the first deadline in an improvised way, but were unable to provide the final report with the incident timeline, the containment measures and the impact analysis. Authorities interpret that lack of traceability as a sign that the security programme did not really exist, and that aggravates the penalty.

The second pattern is the supply chain. In at least two of the known cases, the incident entered through a technology supplier that the organisation had not assessed or contracted in accordance with the directive. NIS2 requires critical third parties to be controlled, and shifting the blame to the supplier does not exonerate the main entity. The practical lesson is that the compliance perimeter includes those who provide you with services, not just your own systems.

The mistakes most punished by national authorities

• Not having declared the organisation to the competent authority as an essential or important entity.
• Absence of a documented incident management procedure with NIS2 deadlines (24h, 72h, final report).
• Lack of a formal and up-to-date risk analysis.
• Unassessed supply chain: NIS2 requires critical third parties to be controlled.
• Management without specific cybersecurity training: the directive holds the management body responsible.
• No business continuity plan tested in the last 12 months.

The common thread of all these mistakes is the lack of evidence. In my experience, organisations usually have some of the controls implemented informally, but do not know how to prove it when the inspector arrives. A security policy approved by the board, a risk analysis with date and signature, training records and continuity test minutes are worth more, in an audit, than a flawless but undocumented technical deployment. Compliance is managed as a project with deliverables, not as an intention.

How to avoid penalties from the project stage

The most effective way to avoid NIS2 penalties is not to wait for the audit. NIS2 is built with the delivery, not against it. Every IT project must be born with risk analysis, defined controls, an incident response plan and archived evidence. I developed this in detail in compliance project management for NIS2.

In practice, this means integrating compliance into the definition of each initiative from day one. When I lead a project in a regulated sector, I incorporate the security requirements into the backlog just like any other functional requirement: with acceptance criteria, owners and traceability. This way, evidence is not manufactured after the fact to pass an inspection, but is generated naturally as the project progresses. It is cheaper, more robust in an audit and far less stressful than the classic last-minute effort.

90-day plan to reduce exposure

1. Days 1-15: confirm whether the organisation falls within scope and register with the national authority.
2. Days 16-30: close the formal risk analysis and approve the security policy.
3. Days 31-50: implement and test the 24/72-hour incident notification procedure.
4. Days 51-70: review contracts with critical suppliers and introduce NIS2 clauses.
5. Days 71-90: train the board and management committee and leave archived evidence.

This schedule is deliberately conservative and can be compressed if the organisation already has part of the work done. What matters is the order: first know whether you are within scope and register, because omitting registration is one of the most penalised breaches; then build the risk analysis, which is the basis on which all controls are justified; and only then fine-tune the operation of incidents, suppliers and training. Trying to implement controls without a risk analysis behind them produces a lot of spending and little defensibility before the authority.

Conclusion: the cost of not acting

NIS2 penalties 2026 are deterrent by design. A fine of several million, added to the reputational damage and the personal responsibility of the board, far exceeds the cost of a well-executed compliance programme. If you want to review your exposure or prioritise investment, let’s talk.

Frequently asked questions about NIS2 penalties

What is the maximum fine for breaching NIS2 in 2026?

Essential entities can receive fines of up to 10 million euros or 2% of their annual global turnover, whichever is higher. Important entities are exposed to up to 7 million or 1.4%. In addition, authorities can impose binding corrective measures and temporarily disqualify executives.

Who is responsible for the penalties within the company?

NIS2 holds the management body directly responsible. The board must approve the risk management measures, oversee their implementation and receive cybersecurity training. Responsibility no longer rests solely with the technical department, but with whoever leads the organisation.

What incident notification deadlines does NIS2 require?

The directive requires an early warning within 24 hours, a detailed notification within 72 hours and a subsequent final report with a timeline, containment measures and impact analysis. The inability to provide that final report is one of the factors that most aggravates penalties.

How can I reduce my exposure before the audit?

Confirm whether your organisation falls within scope and register, close a formal risk analysis, document the incident notification procedure, assess your critical suppliers and train management. An orderly 90-day plan lets you cover the essentials and, above all, generate the evidence the authority requires.
