In order to ensure timely, proportionate and effective measures in relation to products with digital elements presenting a significant cybersecurity risk, a Union safeguard procedure under which interested parties are informed of measures intended to be taken with regard to such products should be provided for. This should also allow market surveillance authorities, in cooperation with the relevant economic operators, to act at an earlier stage where necessary. Where the Member States and the Commission agree as to the justification of a measure taken by a Member State, no further involvement of the Commission should be required, except where non-compliance can be attributed to shortcomings of a harmonised standard.
