NIS2 Article 21 Gap Checker (Ten Cybersecurity Risk-Management Measures)

Assess compliance with NIS2 Article 21's ten mandatory cybersecurity risk-management measures (a–j). Score each measure by implementation status, documentation, and last test date. Receive an overall compliance score (0–100), grade (A–F), and prioritised remediation list.

Scope

Middle node of the nis2-compliance chain (art-141→142→143). Assesses all ten NIS2 Article 21 cybersecurity risk-management measures. Maturity scoring: 3=implemented+tested, 2=implemented only, 1=documented only, 0=absent. Overall score = sum of maturity scores / 30 × 100. Grade A≥90, B≥75, C≥60, D≥40, F<40.

Run the AINumbers MCP tool `check_nis2_art21_measures`. Task: Assess NIS2 Article 21 compliance across ten cybersecurity risk-management measures (a-j).
Call it with arguments: {"policy_parameters":{"measures":[{"measure_id":"a","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"b","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"c","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"d","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"e","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"f","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"g","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"h","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"i","implemented":true,"documented":true,"last_tested_date":"2025-12-01"},{"measure_id":"j","implemented":true,"documented":true,"last_tested_date":"2025-12-01"}]}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
