DZ BANK Whistleblowing system

DZ BANK has implemented a whistleblowing system, which can be used by employees as well as third parties (e.g. clients, suppliers, external employees) in case of suspicious facts of criminal activity or other irregularities, which may lead to reputational or financial losses of DZ BANK. The procedure ensures the confidentiality of the whistleblower’s identity.

Due to the use of the whistleblowing system, the whistleblower does not have to fear any negative consequences, except in case of a demonstrably intentional misuse of the whistleblowing system.

In general, you can always get in touch with us if something seems unusual to you. We listen to you and review and assess your information.

You have the option of contacting our internal or external ombudsman. There do not incur any costs for you when contacting us. You will be informed about the progress of the case as far as the circumstances permit.
