Cybersecurity law in Belgium: NIS2 compliance (2026)
Belgium shaded by its cybersecurity status
Cybersecurity in Belgium: comprehensive law, anchored by Law of 26 April 2024 establishing a framework for the cybersecurity of networks and information systems of general interest for public security (the 'NIS2 Law'), with implementing Royal Decree of 9 June 2024; supervised by the Centre for Cybersecurity Belgium (CCB)..
Belgium has a comprehensive horizontal cybersecurity regime through its NIS2 Law of 26 April 2024 and Royal Decree of 9 June 2024, both in force since 18 October 2024, which transpose EU Directive 2022/2555 (NIS2). The CCB is the national cybersecurity authority and national CSIRT, with sectoral authorities assisting in supervision, and essential/important entities face risk-management duties, registration, and tiered incident-reporting obligations. Sector-specific cybersecurity rules also apply on top, notably the EU DORA Regulation for financial entities (supervised by the NBB and FSMA) and GDPR data-breach notification overseen by the Belgian Data Protection Authority.
NIS2 & cybersecurity law in Belgium
In Belgium, baseline cybersecurity obligations come from the EU NIS2 Directive, transposed into national law, which sets risk-management and incident-reporting duties for essential and important entities.
- Framework
- the NIS2 Directive (EU) 2022/2555, transposed into national law
- Approach
- cybersecurity risk-management measures plus mandatory incident reporting for in-scope entities
- Applies to
- medium and large entities in critical sectors: energy, transport, banking, health, water, digital infrastructure, ICT and public administration
- Incident reporting

- Maximum fine
- up to €10 million or 2% of global annual turnover for essential entities
- Oversight

Key points
The NIS2 Law of 26 April 2024 and Royal Decree of 9 June 2024 entered into force on 18 October 2024, transposing Directive (EU) 2022/2555 and creating Belgium's general cybersecurity framework for entities of general interest.
The Royal Decree designates the Centre for Cybersecurity Belgium (CCB) as the national cybersecurity authority and national CSIRT, supported by designated sectoral authorities for supervision of in-scope sectors.
In-scope entities must notify the CCB of any 'significant' incident: an early warning within 24 hours, an incident notification/update within 72 hours, and a final report within 30 days.
Essential and important entities must register via the Safeonweb@Work portal (deadline 18 March 2025; digital-sector entities 18 December 2024); CyberFundamentals and ISO/IEC 27001 are recognized reference frameworks, with fines up to EUR 10M or 2% of worldwide turnover for essential entities.
Financial entities additionally fall under the EU DORA Regulation, reporting major ICT-related incidents to the National Bank of Belgium (NBB) or FSMA, with an initial notification, an intermediate report within 72 hours and a final report within one month.
Separately from NIS2, personal-data breaches must be reported to the Belgian Data Protection Authority (APD-GBA) within 72 hours; the authority launched a new breach-notification portal in 2025 with a two-part submission process.
