Forty-eight questions professionals ask about proving NIS 2 compliance — governance approval, the ten technical measures of Article 21, incident notification deadlines, supervisory response — each mapped to the SOURCE 0 term that answers it, and to the article of Directive (EU) 2022/2555 it rests on.
