Secure digital collaboration between municipalities and suppliers

The digital resilience of municipalities is increasingly making headlines. Cyber incidents are on the rise, supply chain dependencies are growing, and European and national regulations are becoming ever stricter. With the introduction of the NIS2 Directive/Cybersecurity Act, combined with the updated BIO2 framework, the way municipalities and suppliers collaborate on information security is fundamentally changing.

This means two things:

  • Without demonstrable NIS2 and BIO2 compliance, it is becoming increasingly difficult to work for municipalities.
  • For municipalities, this means: compliance must not only be achieved internally, but it must also be demonstrated that suppliers have taken adequate measures.
  • In this article, we explain what is changing, what the obligations are, and how uComply supports organisations in meeting the requirements.

    NIS2: municipalities and suppliers become essential links in national digital security

    The NIS2 Directive officially classifies municipalities as "essential entities", with legal obligations including a duty of care, a reporting obligation for significant cyber incidents, and even prior audits by the National Inspectorate for Digital Infrastructure (RDI).

    What does this mean for municipalities?

    Municipalities must:

  • Maintain a register of essential processes and systems
  • Demonstrably ensure risk management and security measures
  • Report cyber incidents within legal timeframes
  • Be prepared for RDI inspections
  • What does this mean for suppliers?

    Organisations providing services to municipalities may fall under NIS2. If your service is "essential" to the functioning of a municipality, the same obligations apply.

    BIO2: the standards framework for all municipal information security

    The VNG (Association of Netherlands Municipalities) confirms that the new BIO2 was officially published in March 2026 and serves as guidance for municipalities, with legal enforcement to follow via the Cybersecurity Act.

    BIO2 aligns with ISO 27001 and replaces the former BBN model. It requires fully risk-based security. The Digital Government emphasises that BIO2 measures have been tightened through mandatory alignment with NIS2.

    What does this mean for municipalities?

  • A required information security management system (ISMS)
  • Risk assessments must comply with the BIO2 structure
  • Control measures must be explicitly documented
  • Logging, monitoring, and supply chain security must be demonstrable
  • Suppliers must be demonstrably BIO2-compliant
  • What does this mean for suppliers?

    Municipalities will formally assess whether your service delivery meets BIO2 requirements. This means you must be able to provide:

  • ISO 27001 certification or equivalent evidence
  • Incident and continuity documentation
  • Logging and monitoring information
  • Transparency regarding cloud locations and supply chain dependencies
  • What are the mutual expectations?

    Compliance requirements from municipalities

    NIS2:

  • Essential processes and systems
  • Incident registrations
  • Supply chain risks
  • Audit reports and assessments
  • BIO2:

  • Risk assessments and ISMS documentation
  • Measures derived from ISO/IEC 27001
  • Logging and monitoring setup
  • Business continuity plans
  • What suppliers must deliver

    NIS2 compliance:

  • Incident reporting protocol
  • Risk assessment
  • Evidence of supply chain security
  • Assurance reports
  • BIO2 conformity:

  • ISO 27001 certificate or equivalent evidence
  • Incident and BCM documentation
  • Logging and monitoring information
  • The combination of NIS2 and BIO2 changes the entire playing field:

  • Municipalities must demonstrably work securely and safeguard their supply chain
  • Suppliers must meet the same stringent standards
  • How uComply helps
