Building a NIS2-Compliant Automation Stack Using Self-Hosted n8n

How to Build a NIS2-Compliant Automation Stack Without Buying New Software

Mychel Garzon, founder of AutomiQ, outlines a strategy for achieving EU NIS2 compliance using self-hosted automation. The directive requires significant security incidents to be reported to national authorities within 24 hours of discovery.

Why This Matters

Many SMEs assume compliance requires purchasing expensive new security platforms, whereas the operational requirements—incident detection, access control, and audit trails—can be met by integrating existing systems like Microsoft 365, SAP, and Oracle. The technical gap is not a lack of data, but the absence of an automation layer to tie these systems together and generate the required timestamped audit logs for auditors.

Key Insights

• NIS2 Article 21 mandates strict operational controls including incident handling and supply chain security (enforced October 2024).
• Self-hosting automation on EU infrastructure (e.g., Hetzner or OVHcloud) ensures data sovereignty and direct control over execution logs and credentials.
• Automated User Lifecycle Management replaces manual joiner/mover/leaver processes with Graph API integrations to prevent common audit findings.
• Continuous monitoring via automated weekly posture reports is more effective for auditors than manual spreadsheets.

Practical Applications

• ). Use case: Incident Triage using n8n + AI (GPT-4o/Ollama) to classify severity and trigger 24-hour NIS2 reporting reminders. Pitfall: Manual incident logging leading to missing timestamps and failed compliance audits.
• ). Use case: Third-Party Access Audit using Graph API to flag guest accounts inactive for 30+ days. Pitfall: Granting external collaborator access without a review process, creating persistent security gaps.
