NIS2 for cloud and data-centre providers in Belgium
Cloud and data centres 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
- Cloud computing service providers
- Data-centre service providers
- Content delivery networks
- DNS service providers, TLD registries and trust service providers (in scope whatever their size for several of these)
Companies that only use cloud services are not in scope as cloud providers.
The threats we see most in cloud and data centres
- DDoS and availability attacks
- Tenant-isolation and misconfiguration failures
- Abuse of administrator and API credentials
- Physical and power incidents in data halls
Five priority measures
- 01 Customer-facing incident communication within the legal deadlines
- 02 Privileged-access management and hardware keys for administrators
- 03 Configuration baselines and continuous misconfiguration checks
- 04 Redundancy and recovery tests with documented results
- 05 Register in the country of your head office (NIS2 rule for cloud and data-centre providers)
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.
Registration. Register on Safeonweb@Work (CCB). The general deadline was 18 March 2025 — late registrants should register now.
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).
