NIS2 for transport operators in Luxembourg

Transport is listed in Annex I of the NIS2 directive. Large companies are essential entities; medium companies are important entities. In Luxembourg, the rules come from the Law of 5 May 2026 transposing NIS2, applicable since 10 May 2026; the authority is the Institut Luxembourgeois de Régulation (ILR).

Who is covered in this sector

• Air carriers, airports and air-traffic control
• Rail infrastructure managers and railway undertakings
• Inland, sea and coastal shipping companies, port operators and vessel traffic services
• Road authorities and operators of intelligent transport systems

Ordinary road haulage and logistics companies are not in scope as transport; but they often receive security requirements from in-scope customers — see the supplier questionnaire page.

The threats we see most in transport

• Ransomware on planning, ticketing and warehouse systems
• Attacks on operational systems in ports, rail and aviation
• Fraud and account takeover in booking and payment flows
• Supplier compromise (IT, OT, maintenance)

Five priority measures

1. 01 Map the systems that stop operations if they fail
2. 02 Segment operational networks from office IT
3. 03 MFA and privileged-access control for suppliers
4. 04 Continuity plans with manual fall-back procedures
5. 05 Incident reporting routine for the 24-hour early warning

What Luxembourg requires

• The law of 5 May 2026 was published in the Mémorial A (No. 225) and has applied since 10 May 2026.
• The competent authority is the ILR. Self-registration was due within two months, i.e. by 10 July 2026.
• Entities must adopt a cyber-risk management policy covering the ten minimum measures of the directive (risk analysis, incident handling, business continuity, supply-chain security, cryptography…).
• Incident reporting: early warning within 24 hours, notification within 72 hours, final report within one month.

Significant incidents: early warning within 24 hours, notification within 72 hours, final report within one month. Fines set by the directive: up to €10 million or 2% of worldwide turnover for essential entities, and up to €7 million or 1.4% for important entities (whichever is higher).

Frequently asked questions

Is my transport operator company in scope of NIS2 in Luxembourg?

Transport is an Annex I sector. Large companies are essential entities; medium companies are important entities. Small companies are generally out of scope unless designated. Our NIS2 check gives you the answer in two minutes.

What should we do first?

Register if you are in scope, name an owner, run a short risk assessment, and fix the basics: MFA, tested backups, patching, incident routine.

We are a supplier to this sector. Does it affect us?

Yes, indirectly: your customers must secure their supply chain and will ask you for evidence. See our supplier questionnaire guide.
