Conformity marks
Aware of the need to publicise the guarantees adopted in the performance of public administrations and the development of the administrative procedure provided by electronic means, Article 38 of the ENS on the publication of compliance states: "Public law bodies and entities shall publicise on the corresponding electronic sites the declarations of compliance, and the security marks awarded to them, obtained with respect to compliance with the National Security Framework"..
Depending on the category of the system, a distinction is made between Declaration of Conformity and Certification of Conformity, as described in Guide 809 (Declaration and Certification of Conformity with the ENS):

Distinctive signs
