Slovakia has implemented the EU NIS2 Directive through its national Cybersecurity Act (Zákon o kybernetickej bezpečnosti). The law sets mandatory cybersecurity, governance, and incident reporting requirements for a broad range of public and private organisations that provide services essential to society and the economy.
Like the EU-level NIS2 framework, the Slovak approach expands coverage beyond the original directive, strengthens management accountability, and introduces clearer expectations for risk controls and reporting. Cybersecurity is treated as a regulatory obligation that must be managed at leadership level, not only as an IT issue.
Scope, sectors and covered entities
The Slovak Cybersecurity Act follows the NIS2 model by widening the number of sectors and organisations that fall under mandatory rules.
It applies mainly to medium and large entities in listed sectors, but smaller organisations can also be included if they play a critical role in supply chains or service delivery. The National Cybersecurity Authority (NBU) maintains registers of covered entities, and organisations are expected to verify whether they are in scope.
Two categories define how obligations apply:
- Essential entities: organisations whose disruption would significantly affect critical societal or economic functions
- Important entities: organisations providing highly relevant services, but with slightly lower criticality
The law covers many of the same sectors as the EU NIS2 Directive, including energy, transport, banking, health, water, digital infrastructure, public administration, and managed service providers.
Governance and management accountability
A major shift under NIS2, reflected directly in Slovakia’s implementation, is the focus on leadership responsibility.
Management bodies must approve cybersecurity risk measures, oversee implementation, and ensure sufficient resources are in place. Executives are also expected to understand their obligations through training, and serious neglect can lead to personal consequences, including temporary bans from managerial roles.
Organisations must maintain formal cybersecurity policies, define clear internal responsibilities, and establish review and audit mechanisms. The Slovak transposition reinforces the idea that cybersecurity is a continuous governance cycle, not a one-time compliance project.
Cybersecurity risk management requirements
NIS2 Slovakia requires organisations to take a structured approach to risk management across the systems that support essential or important services.
This includes identifying critical assets, mapping dependencies, assessing threats (technical and non-technical), and documenting risk assessments regularly. Supervisory authorities may request evidence during inspections.
The act also defines a baseline set of measures that entities must implement proportionately. These expectations closely mirror the EU directive and typically include:
- incident handling and crisis management
- business continuity and backup planning
- secure system development and acquisition
- access control, encryption, logging, and monitoring
- vulnerability management and patching
- staff awareness and cybersecurity training
- supplier and supply chain risk controls
Supply chain security is particularly emphasised, aligning with NIS2’s focus on third-party exposure across Europe.
Incident reporting and crisis coordination
Incident reporting is one of the most operationally demanding parts of NIS2, and Slovakia follows the directive’s staged reporting model.
Entities must notify the national CSIRT or competent authority when incidents substantially affect service delivery. Reporting is based on impact factors such as duration, user disruption, geographic spread, financial loss, and effects on safety or public order.
The process typically includes an early warning, followed by a detailed notification and a final report summarising root causes and remediation.
Because Slovakia’s act operates within the wider EU NIS2 cooperation framework, incident information may also be shared across Member States when cross-border impacts exist. Organisations may need to provide additional technical details or support coordinated analysis.
Supervision, enforcement and penalties
The Slovak Cybersecurity Act grants strong supervisory and enforcement powers to national competent authorities and the national CSIRT.
Authorities can issue guidance, conduct inspections, request documentation, and require improvement plans. Enforcement tools reflect the stricter NIS2 approach across the EU.
Penalties may include administrative fines, binding remediation orders, suspension of certain activities, and increased audit obligations. Management liability is also possible in cases of serious or persistent non-compliance, and public disclosure of enforcement actions can carry reputational impact.
Integration with other frameworks and practical implementation
NIS2 Slovakia does not exist in isolation. Organisations often need to align compliance with other EU and national requirements, including GDPR, DORA (for financial services), and sector-specific resilience rules.
Many organisations build integrated security management systems using standards such as ISO/IEC 27001 or ISO 22301, then tailor them to Slovak NIS2 obligations like reporting channels and supervisory expectations.
A practical implementation programme usually starts with scope confirmation, maturity assessment, and gap remediation, then evolves into embedding cybersecurity into procurement, change management, and daily operations.
FAQ: NIS2 Slovakia
What is NIS2 Slovakia?
NIS2 Slovakia refers to Slovakia’s national implementation of the EU NIS2 Directive through the Slovak Cybersecurity Act.
Who must comply with the Slovak Cybersecurity Act?
Essential and important entities across sectors such as energy, transport, health, banking, digital infrastructure, public administration, and managed service providers.
What is the difference between essential and important entities?
Essential entities support critical functions where disruption would have major impact, while important entities provide highly relevant services with slightly lower criticality.
What are the main obligations under NIS2 Slovakia?
Governance accountability, documented risk management, baseline cybersecurity controls, supply chain security, and strict incident reporting timelines.
How fast do incidents need to be reported?
Slovakia follows the EU NIS2 staged reporting approach, starting with an early warning shortly after awareness, followed by detailed notification and a final report.
What happens if an organisation fails to comply?
Authorities can impose fines, remediation orders, operational restrictions, and in serious cases personal consequences for management.
How does NIS2 Slovakia relate to the EU's NIS2?
The Slovak Cybersecurity Act directly adapts the EU directive’s requirements into national law, expanding sector coverage, strengthening enforcement, and embedding Slovak authorities into EU-wide coordination mechanisms.
