Amendment 520· eIDAS Regulation Article 45a(3a)

Providers of web-browsers shall not take any measures contrary to their obligations set out in Article 45, in particular the requirements to recognise qualified certificates for website authentication and to display the identity data provided in a user-friendly manner.

By way of derogation from paragraph 1 and only in the event of substantiated concerns related to security breaches or the loss of integrity of an identified certificate or set of certificates, providers of web-browsers may take precautionary measures in relation to that certificate or set of certificates.

Where a provider of a web-browser takes precautionary measures pursuant to paragraph 2, the provider of the web-browser shall notify its concerns in writing, without undue delay, together with a description of the measures taken to mitigate those concerns, to the Commission, the competent supervisory body, the entity to whom the certificate was issued and to the qualified trust service provider that issued that certificate or set of certificates. Upon receipt of such a notification, the competent supervisory body shall issue an acknowledgement of receipt to the provider of the web-browser in question.

The competent supervisory body shall investigate the issues raised in the notification in accordance with Article 46b(4), point (k). Where the outcome of that investigation does not result in the withdrawal of the qualified status of the certificate, the supervisory body shall inform the provider of the web-browser accordingly and shall request that provider to put an end to the precautionary measures referred to in paragraph 2 of this Article.
