NIS2 Directive Compliance Advisory
EU Network and Information Security Directive
NIS2 enforcement has begun across multiple EU member states, with fines up to 2% of annual turnover or €10M. Taiwan enterprises in EU supply chains face indirect obligations through supply chain security clauses. Winners Consulting guides you from applicability assessment to 72-hour incident reporting SOP.
⏱ NIS2 Phased Timeline
Does NIS2 Apply to Taiwan Enterprises? How to Determine Applicability?
NIS2 (Directive EU 2022/2555) is the EU's second-generation network and information security directive, requiring medium and large enterprises across 18 critical sectors to establish systematic cybersecurity management, implement supply chain security, and report major incidents to authorities within 72 hours. Three applicability scenarios for Taiwan enterprises: (1) Companies with EU branches or directly providing services at Annex I/II scale thresholds; (2) Direct suppliers to EU essential/important entities subject to supply chain security clauses; (3) SaaS/MSP/MSSP providers to EU digital service businesses, classified as Annex II digital service providers.

Frequently Asked Questions
What is NIS2? How does it differ from the original NIS?▾
NIS2 (EU 2022/2555) is the EU's second-generation network and information security directive, requiring member states to transpose it into national law by October 2024. Compared to NIS1, NIS2 significantly expanded scope (from 7 to 18 sectors, covering ~160,000 EU entities), raised minimum security requirements, introduced management personal liability, and unified incident reporting timelines to 24-hour early warning / 72-hour formal notification.
Does NIS2 apply to Taiwan enterprises? What are the criteria?▾
NIS2 applies to organizations providing services in the EU, regardless of where they are headquartered. Per Article 2 + Article 3 (Directive (EU) 2022/2555): [Essential Entity] Operates in one of 11 Annex I sectors AND employs ≥250 persons AND annual turnover >€50M or balance sheet >€43M; OR qualified trust service provider/TLD registry/DNS provider (regardless of size). Subject to proactive ex-ante supervision. [Important Entity] Operates in any of 18 Annex I or II sectors AND employs ≥50 persons AND annual turnover >€10M or balance sheet >€10M. Subject to reactive ex-post supervision. Note: Size threshold requires BOTH employee count AND revenue/assets simultaneously (not OR). Even if not directly applicable, Taiwan suppliers to EU critical entities face indirect obligations via supply chain security clauses (Article 21(2)(d), Directive (EU) 2022/2555).
What are the 10 minimum cybersecurity measures under NIS2?▾
NIS2 Article 21 requires 10 minimum measures: (1) cybersecurity policies and risk analysis; (2) incident handling; (3) business continuity and crisis management; (4) supply chain security; (5) network/system procurement and development security; (6) vulnerability management and disclosure; (7) cybersecurity effectiveness assessment; (8) basic cyber hygiene (MFA, encryption); (9) cybersecurity training and awareness; (10) HR security and access control.
How does NIS2 incident reporting work? What does the 72-hour deadline mean?▾
NIS2 requires three-stage reporting for "significant incidents": (1) 24-hour early warning; (2) 72-hour formal notification with detailed technical report; (3) 1-month final report. A "significant incident" is defined as causing serious disruption to service delivery or significant harm to other entities or public interests.
What is NIS2 management personal liability? Can directors and CEOs be penalized?▾
NIS2 Article 20 holds management personally accountable for approving and overseeing cybersecurity risk management measures. Where organizational NIS2 violations result from management "gross negligence," authorities may temporarily ban individuals from management roles, publicly disclose violations, and fine the organization up to €10M or 2% of annual turnover.
What is the relationship between NIS2 and ISO 27001? Is ISO 27001 sufficient?▾
ISO 27001 provides a strong ISMS foundation that can significantly shorten NIS2 preparation time. However, NIS2 additionally requires specific incident reporting timelines, registration with EU authorities, supply chain security assessment procedures, and management personal liability mechanisms that must be built on top of ISO 27001. Winners Consulting provides integrated ISO 27001 + NIS2 advisory.
How long does NIS2 advisory take? How is pricing calculated?▾
From gap analysis to completed institution building, NIS2 advisory typically takes 4-6 months, reduced to 2-3 months for organizations with existing ISO 27001 foundations. Pricing depends on organizational size, existing framework maturity, and target member state. Initial consultation is free.
