    NIS2 in Croatia

    A guide to NIS2 implementation and compliance in Croatia.

    Croatia is aligning its national cybersecurity framework with the strengthened EU regime under the NIS2 Directive. The updated legislation expands scope, governance duties, reporting timelines, and enforcement exposure for covered entities. This guide provides a structured overview of NIS2 compliance Croatia obligations for SMEs operating in regulated sectors.

    1. Quick SME Applicability Snapshot in Croatia

    Does NIS2 apply to SMEs in Croatia?

    Yes — depending on sector and size.

    • Automatic applicability to medium-sized entities (≥50 employees and ≥€10 million turnover or balance sheet total) operating in covered sectors.
    • Small or micro entities are included only if formally designated or operating in high-criticality sectors.
    • Applies to entities established in Croatia and, in certain cases, foreign digital providers offering services in Croatia.

    SMEs should assess whether they fall within Croatia's national cybersecurity regime based on sector and size thresholds.

    2. Overview of NIS2 Implementation in Croatia

    Croatia is implementing NIS2 through amendments to the Cybersecurity Act, which governs the security of network and information systems at national level.

    The updated statutory framework aligns Croatia's regime with Directive (EU) 2022/2555, expanding sector coverage, strengthening governance accountability, and formalizing reporting obligations.

    The legislation modernizes supervisory powers and administrative sanction structures in accordance with the Directive.

    3. Scope of Application in Croatia

    Croatia's scope reflects Directive minimum categories without confirmed structural expansion.

    4. Size Thresholds and SME Applicability in Croatia

    The Directive baseline thresholds apply:

    • ≥50 employees, and
    • ≥€10 million annual turnover or balance sheet total.

    Entities meeting both criteria within covered sectors are automatically in scope.

    Small and micro enterprises may be designated if considered critical to public security, economic stability, or societal functioning.

    Croatian authorities retain formal designation powers where risk exposure justifies inclusion.

    5. Entity Classification Framework in Croatia

    Entities are classified as:

    • Essential Entities — Subject to proactive supervision, including inspections and structured compliance monitoring.
    • Important Entities — Subject primarily to reactive supervision, triggered by significant incidents or compliance concerns.

    Classification is determined by sector and size. Competent authorities may reclassify entities where operational impact or systemic risk warrants stricter oversight.

    Croatia follows the Directive's two-tier supervisory model.

    6. Cybersecurity Risk Management Requirements in Croatia

    Croatia's national regime aligns with Directive baseline obligations. In-scope entities must implement proportionate technical and organizational measures covering:

    • Risk analysis and system protection
    • Incident detection and response
    • Business continuity and crisis management
    • NIS2 supply chain Croatia risk controls
    • Secure acquisition and development of ICT systems
    • Access control and authentication safeguards
    • Encryption and cryptographic protection
    • Vulnerability handling procedures
    • Staff cybersecurity training

    Measures must reflect state-of-the-art standards and the entity's risk profile. Alignment with ISO/IEC 27001 and recognized Croatian cybersecurity guidance is encouraged.

    Supply chain risk management includes vendor due diligence and contractual cybersecurity requirements.

    7. Management Liability and Governance in Croatia

    Management bodies must formally approve cybersecurity risk management measures and oversee implementation.

    Under Croatia's framework:

    • Boards are accountable for ensuring compliance.
    • Senior management must maintain adequate cybersecurity awareness.
    • Administrative sanctions may address governance failures.
    • Temporary suspension of managerial functions may be available under Directive-aligned enforcement mechanisms.

    NIS2 management liability Croatia standards elevate cybersecurity to executive-level responsibility.

    8. Incident Reporting Obligations in Croatia

    Definition of a Significant Incident

    An incident qualifies as significant if it causes:

    • Severe operational disruption
    • Significant financial loss
    • Substantial societal impact
    • Cross-border effects

    Reporting Timeline

    Reporting StageDeadlineAuthority
    Early Warning24 hoursNational CERT (CERT.hr)
    Incident Notification72 hoursNational CERT (CERT.hr)
    Final Report1 monthNational CERT (CERT.hr)

    Croatia follows the Directive structure for NIS2 reporting deadlines. Sectoral regulators may coordinate with CERT.hr where applicable.

    9. Supervisory Authorities and Enforcement Model in Croatia

    Primary coordinating authority: National CERT (CERT.hr).

    Croatia operates a centralized model supported by sector-specific regulators where relevant.

    Supervisory powers include:

    • Information requests
    • Security audits
    • On-site inspections
    • Binding compliance instructions
    • Participation in EU cybersecurity cooperation frameworks

    The enforcement structure aligns with Directive-level coordination requirements.

    10. NIS2 Fines and Sanctions in Croatia

    Croatia applies Directive-aligned administrative penalties.

    Essential Entities

    Up to €10 million or 2% of total global annual turnover (whichever is higher)

    Important Entities

    Up to €7 million or 1.4% of total global annual turnover (whichever is higher)

    NIS2 fines Croatia enforcement may also include:

    • Binding remediation orders
    • Public identification of non-compliant entities
    • Suspension of certifications or authorizations
    • Managerial suspension powers

    Criminal liability applies only where explicitly provided under Croatian legislation.

    11. NIS2 Supply Chain and Vendor Security in Croatia

    Entities must manage third-party cybersecurity exposure through:

    • Vendor risk assessments
    • Contractual security flow-down provisions
    • Continuous ICT supplier monitoring
    • Concentration risk analysis
    • Incident propagation controls

    Croatia's approach aligns with Directive baseline supply chain expectations without confirmed national expansion.

    12. Registration and Self-Identification Duties in Croatia

    Entities within scope must:

    • Register with competent authorities
    • Provide corporate identification details
    • Disclose sector classification
    • Maintain updated incident reporting contacts

    Procedural deadlines follow Croatia's implementing framework. As of the current transposition status, Croatia follows the NIS2 Directive baseline framework. National implementing details may refine specific obligations.

    Self-identification is mandatory for entities meeting statutory criteria.

    13. Interaction With GDPR and Other Laws in Croatia

    The General Data Protection Regulation continues to apply concurrently.

    Overlap considerations include:

    • 72-hour personal data breach notification obligations
    • Supervisory authority coordination
    • Parallel cybersecurity and data protection investigations
    • Sector-specific Croatian cybersecurity rules

    A single incident may trigger dual reporting under both regimes.

    14. Cross-Border Applicability

    Entities with their main establishment in Croatia are supervised by Croatian authorities for cross-border services.

    Foreign digital providers offering services in Croatia may be subject to Croatian oversight depending on establishment structure.

    Representation requirements follow Directive standards for non-EU providers serving Croatian markets.

    15. Implementation Timeline in Croatia

    • Directive adoption: 2022
    • National legislative amendments: 2024–2025
    • Entry into force: Upon national publication
