Incident reporting workflow.
NIS2 Article 23 adds a 24-hour early warning and a 72-hour notification on top of GDPR Article 33. We pre-build the workflow, prepare the templates and triage the incident as soon as it is detected.

TREND 01
Management bodies are personally liable
Article 20 makes management bodies responsible for approving the risk-management measures and overseeing implementation. Authorities have begun fining individuals, not just the entity.
TREND 02
Supply chain is the new scope of audit
Article 21(d) requires assessment of direct suppliers and service providers. Authorities now request documented vendor reviews as standard.
TREND 03
Group-level scoping is non-trivial
Subsidiary structures, EU establishment rules, and main-establishment principles drive which authority is competent. Wrong assumptions trigger re-filings.
08 / FAQ
Common questions.
01How do we know if we are in scope?+
Two tests. First, sector: Annex I or Annex II of NIS2. Second, size: above 50 staff or €10M turnover (important) or above 250 staff or €50M turnover (essential). There are also size-independent triggers for certain sectors. We run the assessment in week one.
02We are based outside the EU but serve EU clients. Do we apply?+
Sometimes. Article 26 establishes scope for non-EU providers of specific services (DNS, cloud, datacentre, content delivery, online marketplace, online search, social networking). A representative in the EU may be required under Article 26(3).
03How long does NIS2 implementation take?+
4 to 6 months for a typical mid-market organisation. Two months on scoping, three months on Article 21 measures and reporting workflow, one month on management training and pre-supervisory readiness review.
04What happens at the 24-hour and 72-hour deadlines?+
At 24 hours, we file an early warning indicating suspected malicious cause to the CSIRT or competent authority. At 72 hours, we file the incident notification with updated assessment, indicators of compromise, and initial mitigations. We coordinate both filings, including authority follow-ups.
05Do we need ISO 27001 for NIS2?+
No. NIS2 does not mandate ISO 27001. The two frameworks overlap heavily in technical measures, so a single information security programme satisfies both. ISO 27001 certification is a business decision driven by customer and tender requirements.
06How do you handle group-level scoping?+
We map subsidiaries to sectors and size thresholds, establish main-establishment rules under Article 26, and define group reporting cadence. Where multiple jurisdictions apply, we coordinate the single point of contact and prevent double-filing.
