"DEHN protects" - A promise that we keep day after day - for our customers, partners and employees.

The success of our company is based not only on the quality of our products, but above all on our good reputation and the trust placed in us. As a company, we are expressly committed to integrity, sustainability, fairness, respect and responsibility in business interactions.

Please always be aware that the reputation and good name of our company are significantly influenced by the appearance and behavior of each of us.

In order to be able to avert possible damage in connection with our business activities, it is important to us to become aware of possible legal infringements at an early stage.

With this in mind, we offer an independent whistleblower service that is managed by Deloitte on behalf of DEHN. We call this service DEHNspeakup.

DEHN takes the handling of whistleblower reports via DEHNspeakup very seriously, processes every submitted report and initiates investigations if possible and necessary. We want to effectively protect you as a whistleblower.

DEHNspeakup is designed to record whistleblowers reporting violations of Union law, as well as violations of German law, in accordance with the EU Directive on the Protection of Individuals (EU 2019/1937). 

DEHNspeakup also includes the function of the complaint procedure according to the Act on Corporate Due Diligence Obligations in Supply Chains and enables persons to point out human rights and environmental risks, as well as violations of human rights-related or environmental obligations, which have arisen due to the economic actions of the DEHN company in its own business area - i.e. itself - or of a direct or indirect supplier of DEHN.
