NIS2 Gap Analysis

The NIS2 Directive establishes comprehensive requirements for cybersecurity measures, risk management, and governance structures. A professional gap analysis systematically identifies all areas where adjustments are required and forms the basis for structured and cost-effective implementation. Our proven methodology ensures complete compliance readiness.

Our NIS2 Gap Analysis Service provides comprehensive and systematic assessment of your current cybersecurity status against NIS2 requirements. We identify all compliance gaps and develop concrete action recommendations.

Frequently asked questions about NIS2 Gap Analysis

What is a NIS2 gap analysis?

A NIS2 gap analysis is a structured assessment that compares your organization's current cybersecurity maturity against the NIS2 Directive requirements (especially Art. 21). The output is a clear picture of all compliance gaps, prioritized by risk and implementation effort. The gap analysis is the essential first step before any NIS2 implementation. Without knowing your current state, no meaningful roadmap can be built.

How does a NIS2 gap analysis work?

A professional NIS2 gap analysis follows five steps: 1) Scoping (which systems, locations and processes are in scope?), 2) Document review (existing policies, ISMS documentation, protocols), 3) Interviews & technical assessment (conversations with IT, management and business units, system reviews), 4) Gap evaluation (traffic-light rating per area: red/yellow/green with risk classification), 5) Reporting & roadmap (prioritized action plan with quick wins and medium-term measures).

What NIS2 areas does the gap analysis cover?

A complete NIS2 gap analysis reviews all ten Art. 21 security domains: risk analysis and security policies, incident handling, business continuity, supply chain security, secure development/procurement, effectiveness measurement, cyber hygiene/training, cryptography, personnel security, and MFA/authentication. Additionally, governance (Art. 20), BSI registration obligations and sector-specific requirements are assessed.

How long does a NIS2 gap analysis take?

Duration depends on the size and complexity of the organization: medium-sized entities (50–250 employees) typically 2–4 weeks; larger enterprises with complex IT landscapes 6–8 weeks. A typical breakdown: 1 week preparation and document review, 1–2 weeks technical assessment and interviews, 1 week analysis and reporting. Remote-based assessments can slightly compress the timeline.

NIS2 gap analysis vs. NIS2 audit: what is the difference?

The gap analysis is an internal or consulting-based assessment without formal certification. It serves preparation and roadmap development. A NIS2 audit is a formal examination by accredited bodies or authorities (BSI for essential entities in Germany) that attests actual compliance. Best practice: conduct the gap analysis first to close gaps, then pursue the audit as evidence for supervisory authorities.

What does a NIS2 gap analysis cost?

Costs vary significantly by scope and entity size: SMEs with manageable IT landscapes: from approximately €15,000–30,000. Medium-sized entities: €30,000–80,000. Large essential entities with complex infrastructure: €80,000–200,000 and above. Compared to potential NIS2 fines (up to EUR 10 million or 2% of global annual revenue), a professional gap analysis is a clear investment in risk avoidance.
