Do you have special or insider knowledge of illegal agreements (cartels), an abuse of market power or other competition infringements but are reluctant to pass this information on for fear of reprisals or negative consequences?

The guarantee of your anonymity offered by this system has been certified by a publicly appointed and sworn expert. There is no technical possibility of tracing information that you have submitted back to you as long as you do not enter any data which allows conclusions to be drawn about your identity. Further information on the whistleblowing system is available online at
