NIS2 for transport operators in Belgium

Transport is listed in Annex I of the NIS2 directive. Large companies are essential entities; medium companies are important entities. In Belgium, the rules come from the NIS2 Law of 26 April 2024, applicable since 18 October 2024; the authority is the Centre for Cybersecurity Belgium (CCB), plus a sector authority for some sectors.

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 Belgium requires

• The law of 26 April 2024 has applied since 18 October 2024.
• Registration on Safeonweb@Work was due by 18 March 2025 (18 December 2024 for some digital providers). Not registered yet? Do it now.
• Essential entities had to complete a first conformity assessment by 18 April 2026 and must hold CyberFundamentals (CyFun®) or ISO/IEC 27001 certification by 18 April 2027.
• The CCB framework has three assurance levels — Basic, Important, Essential. Basic is recommended for suppliers of NIS2 entities that are not in scope themselves.
• Important entities are supervised after the fact (for example after an incident); a voluntary CyFun® or ISO 27001 assessment gives them a presumption of conformity.

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 Belgium?

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.
