Whistleblow services

A whistleblow program is one of the most effective measures in the prevention and detection of fraud

According to research (ACFE Report to the Nations - 2022), it is estimated that each year 5% of revenue is lost due to fraud. In fact, fraud losses are two times higher in organizations without whistleblow channels. The report confirms that a whistleblow channel is one of the most effective measures to reduce the loss of fraud by 50%. Not only is it an important measure in the prevention of fraud, it equips organizations with a signal function allowing them to more easily identify fraud, being the first to know about it and avoid incremental fraud losses.

Ensure compliance

In view of the Belgian regulations (based on EU Directive 2019/1937) with respect to the protection of persons who report breaches of Union Law, organizations will need to organize an internal whistleblowing channel and ensure the protection of the whistleblower. More specifically the scope entails:

  • As of 15 February 2023: legal entity with +250 employees
  • As of 17 December 2023: legal entity with +50 employees

These organizations are required to enable a potential whistleblower (usually an employee) to anonymously report on information, including reasonable suspicions, about actual or potential breaches that have taken place or are highly likely to take place within the work-related context. The scope of these breaches is very broad and includes: Public procurement, product safety, food safety, privacy, security of network, consumer protection, transport safety, protection of the environment, public health, tax fraud and evasion etc.

Is it just a matter of compliance?

Demonstrating compliance should be a key objective but more important are the opportunities that will be derived from an effective whistleblow program.

Besides preventing and quickly detecting fraud and consequently mitigating financial fraud risks, a whistleblow program including an internal reporting channel, is a fundamental part of the organization’s Corporate Social Responsibility, it’s a way to respect employees and promote an open and transparent culture.  Organizations that understand the positive value and effect on their reputation will benefit from more trustworthy relationships with their stakeholders.
