Help us report misconduct and malpractice within our organization or among our partners.




We follow up on every report consistently.

Please use our accessible Whistleblowing Portal for complaints, questions regarding your rights, potential misconduct, or product safety risks.

This channel is available in multiple languages, and all communication is treated anonymously and confidentially!

How it works:

  • Simply select one of the three topics relevant to you, and you will be redirected immediately to the corresponding Leineweber portal.
  • On the reporting page, describe your concern as precisely as possible and answer the preset questions. To help us better understand the situation, you can attach files up to a maximum of 100 MB to your report.
  • You will receive an automated confirmation once your report has been submitted. We will then review the facts and contact you via the secure mailbox.
  • Detailed information can be found directly in the Whistleblowing Portal.
