On the territory of the Slovak Republic, we have at our disposal the Whistleblower Protection Office.

The Whistleblower Protection Office was established to provide advice and support to those who report unfair activities that threaten the public interest. These are mainly crimes and offenses that have a negative impact on society and go beyond the interest of the individual.

As an external reporting channel, the Office also receives information on potential misconduct. External reporting channel is: https://www.oznamovatelia.sk/en/chcem-oznamit/

In addition to the Whistleblower Protection Office, the authority competent to receive a hint is also the Public Prosecutor's Office or the relevant administrative or other authority or institution within the meaning of the Act on the Protection of Whistleblowers.
