Competent Authority
The national body in an EU member state responsible for supervising NIS2 compliance.
Explained in depth: Who NIS2 applies to
Each country designates one or more competent authorities that register in-scope entities, conduct audits, and enforce penalties. The specific authority differs by country and sometimes by sector — a bank and a water utility in the same member state may answer to different supervisors — so a multi-country group needs a register of which authority applies where.
