Last update

Providers of intermediary services (network infrastructure providers, hosting service providers, online platforms or search engines, etc.) must comply with a number of obligations under the EU's Digital Services Act (DSA Regulation).

These obligations include guaranteeing a high level of protection for minors, their privacy, safety and security.

If, as a user of an online platform, you believe that there has been an infringement of these obligations, you may file a complaint with the Competition Authority:

  • through an online procedure via MyGuichet.lu either with or without authentication; or
  • via the PDF complaint form to be sent by email or post.

You can find all the details and information about this procedure in our explanatory information page.
