NIS2 Implementation Strategy

A NIS 2 implementation strategy is a tailored master plan for systematically fulfilling all NIS 2 requirements within your organization. It goes beyond a simple checklist: it defines strategic objectives, risk-based and resource-based priorities, clear accountabilities and measurable success indicators, ensuring NIS 2 compliance is sustainably integrated into your IT governance.

A complete NIS 2 strategy covers: gap analysis as the starting point, risk-based prioritization of measures (quick wins first), resource and budget planning, governance structures (accountabilities, escalation paths), technology roadmap (ISMS, SIEM, MFA, encryption), supplier management strategy (Art.

21 supply chain), training strategy (Art.

20 management), documentation and evidence framework, and KPIs for effectiveness measurement.

SMEs need a lean, resource-efficient NIS 2 strategy: focus on proportionality (Art.

21 Para.

1 requires appropriate measures, not over-engineering), leveraging BSI baseline protection as a foundation, prioritizing absolute minimum requirements (registration, incident notification process, risk analysis), and potentially using managed security services instead of building an in-house ISMS. The NIS 2 implementation law provides no blanket SME exemption. Proportionality is the key.

Both approaches have merits: internal implementation is more cost-effective but requires substantial cybersecurity expertise and ties up capacity. External consulting brings NIS 2 specialist knowledge, market overview, proven methodology and independent assessment. A proven hybrid model works well: external consulting for strategy, gap analysis and critical phases; internal team for ongoing implementation and operations. For essential entities facing proactive supervisory oversight, external expertise is strongly recommended.

Prioritization follows three criteria: 1) Regulatory urgency (BSI registration, incident reporting obligation: implement immediately), 2) Risk reduction (which measures reduce the greatest security risk?), 3) Effort-to-benefit ratio (high-impact, low-effort quick wins first). Technical immediate measures (MFA, patch management, backup) can run in parallel with organizational governance measures.

For financial institutions subject to both NIS 2 and DORA, an integrated strategy is the way forward: DORA applies as lex specialis and supersedes NIS 2 requirements for regulated financial entities in overlapping areas. Both share core elements: ICT risk management, incident reporting, third-party management. A consolidated strategy avoids duplication, creates efficiency and ensures no regulatory requirements are overlooked.
