Frequent questions

What is Whistler and how does it work?

Whistler is an application for reporting suspected misconduct that allows a whistleblower to make a disclosed or anonymous report in good faith.

Regardless of whether the whistleblower has revealed his identity or has remained anonymous, he determines a username and password when entering the application for the first time. With both authentication elements, they then enter the application, through which communication with the investigator and monitoring of the reporting process also runs. The report can be supplemented at any time, add documentation or talk to the investigator ("chat") via the dialog box.

Whistler is located on an external portal: NLB Whistler, which allows applications to be made from the external environment, e.g.: from the library, catering establishment...

It is extremely important for an individual to remember their username and password. The password is not stored, and the logger cannot recover a forgotten password. A new login will be required to re-establish contact, and the second login will not allow access to content that is linked to the previous (forgotten) username and password.

Even if you forget your login details, you can log in to the application again at any time with a different username and password, and in the new (additional) login, inform the investigator of the previous report, which will still be visible to the investigator.

Who will process the report (who are the investigators)?

The whistleblower's notification is received only by reporting officers, who are also trustees under the law governing the protection of whistleblowers.


Protection of whistleblowers

When receiving, handling, investigating and archiving an individual report, the reporting officer ensures that the data of the report and thus of the whistleblower are strictly protected. This ensures full protection of the whistleblower throughout the procedure and even after the conclusion of the procedure. If, despite the protection, the whistleblower does not want to reveal his or her identity, it will not be known to the reporting officer due to the possibilities provided by the application, with whom the whistleblower will nevertheless be able to communicate unhindered.

Additional protection of the whistleblower is also provided by law at the state level. As part of the implementation of the law, the bank has appointed trustees who carry out the prescribed procedures under the law.
