Whistleblowing: Definition, legal framework and implementation in Procurement
November 19, 2025
Whistleblowing refers to the reporting of grievances, legal violations or ethical problems by employees or external persons to the responsible bodies. Whistleblowing is becoming increasingly important in Procurement as supply chains become more complex and regulatory requirements increase. Find out below what whistleblowing is, what legal obligations exist and how companies implement effective reporting systems.
Key Facts
- Whistleblowing has been legally regulated by the Whistleblower Protection Act in Germany since 2023
- Companies with 50 or more employees must set up internal reporting channels
- Whistleblowers are protected from retaliation
- Reports can be made anonymously or confidentially
- Violations of supply chain laws are reportable facts

What is whistleblowing? Definition and legal framework
Whistleblowing involves the systematic recording and processing of information on legal violations or abuses in companies.
Core elements of the whistleblowing system
A functioning whistleblowing system consists of several components:
- Secure reporting channels for internal and external whistleblowers
- Confidential processing of reports received
- Protection against retaliation
- Documentation and tracking of cases
Whistleblowing vs. traditional compliance procedures
In contrast to regular audit processes, whistleblowing enables the proactive detection of wrongdoing through insider knowledge. While compliance measures have a preventative effect, whistleblowing reacts to breaches that have already occurred.
Importance of whistleblowing in Procurement
Procurement is particularly susceptible to corruption, conflicts of interest and breaches of supply chain due diligence obligations. Whistleblowing systems help to identify risks in the supplier base at an early stage and strengthen due diligence processes.
Implementation, obligations and evidence
The practical implementation of whistleblowing systems requires structured processes and clear responsibilities.
Setting up internal reporting channels
Companies must establish secure and accessible reporting channels. These include digital platforms, hotlines or personal contacts. It is particularly important to guarantee anonymity and protect against technical manipulation.
Processing process and deadlines
Notifications received must be confirmed within seven days and finally processed within three months. The process requires:
- Initial assessment of the message for plausibility
- Initiation of investigative measures
- Documentation of all steps
- Feedback to the whistleblower
Integration into existing compliance structures
Whistleblowing systems should be dovetailed with existing whistleblowing systems and compliance programs. This enables a holistic risk assessment and efficient use of resources.

Compliance indicators and rates for whistleblowing
The effectiveness of whistleblowing systems is measured using specific performance indicators.
Quantitative performance measurement
Key performance indicators include the number of reports received, processing times and clarification rates. A low number of reports can indicate both a functioning compliance system and a lack of trust in the reporting system.
Qualitative evaluation criteria
The quality of the system is determined by the following factors:
- Whistleblower satisfaction with the handling process
- Completeness of the investigations
- Appropriateness of the measures taken
- Preventive effect on future violations
Benchmarking and industry comparisons
Regular comparisons with industry averages help to evaluate the company's own performance. Key figures on processing times, clarification rates and the distribution of notification categories in the purchasing area are particularly relevant.
Risks, dependencies and countermeasures
Whistleblowing systems entail specific risks that must be minimized through appropriate measures.
Misuse and false reports
Malicious or unfounded reports can tie up resources and burden employees. Preventive measures include clear communication about the purpose of the system and sanctions in the event of proven misuse.
Data protection and confidentiality
The processing of sensitive information harbors data protection risks. Companies must implement technical and organizational measures:
- Encryption of all communication channels
- Access controls and authorization management
- Regular safety audits
- Training of the employees involved
Reputational risks with public reports
External reports to authorities can lead to reputational damage. Effective internal processing and transparent communication help to maintain the trust of stakeholders and avoid regulatory intervention.

Practical example
An automotive supplier implements a digital whistleblowing system following a case of corruption in procurement. An employee uses the anonymous platform to report that a supplier is systematically issuing excessive invoices and paying commissions to buyers in return. The system automatically forwards the report to the compliance department, which initiates an investigation within 48 hours. Thanks to the rapid response, further damage can be prevented and the supplier contract can be terminated without notice.
- Anonymous reporting protects the whistleblower from retaliation
- Automated forwarding speeds up processing
- Documentation of all steps ensures legal certainty
Current developments and interpretation of whistleblowing
The whistleblowing landscape is constantly evolving, driven by new technologies and increased regulation.
Digitalization and AI-supported analysis
Modern whistleblowing platforms use artificial intelligence for the automated initial assessment of reports. AI systems can recognize patterns, carry out risk assessments and set priorities, which significantly increases processing efficiency.
Extended reporting obligations due to EU directives
The EU Whistleblowing Directive extends the scope of application to other areas of law. New reporting obligations in connection with the Corporate Sustainability Due Diligence Directive and environmental protection regulations are particularly relevant for Procurement .
International harmonization
Multinational companies face the challenge of harmonizing different national whistleblowing laws. Uniform global standards are becoming increasingly important in order to reduce compliance costs and create legal certainty.
Conclusion
Whistleblowing is becoming an indispensable tool for compliance in Procurement. The legal requirements create clear obligations, while technological developments facilitate implementation. Companies that invest in professional whistleblowing systems at an early stage can minimize risks and protect their reputation. Success depends largely on integration into existing compliance structures and the creation of a trusting reporting culture.
FAQ
What are the most important legal bases for whistleblowing?
The Whistleblower Protection Act (HinSchG) of 2023 transposes the EU Whistleblowing Directive into German law. Companies with 50 or more employees must set up internal reporting channels and protect whistleblowers from retaliation. Industry-specific regulations such as the Supply Chain Due Diligence Act also apply.
How can companies ensure the quality of reports?
Clear communication about reportable issues, training for employees and structured reporting forms improve quality. In addition, companies should establish feedback mechanisms and provide regular information on how reports are handled in order to build trust.
What are the costs of implementation?
The costs vary depending on the size of the company and the solution chosen. Digital platforms cost between 5,000 and 50,000 euros per year, plus personnel costs for processing and training. External service providers can be a cost-effective alternative.
How does whistleblowing affect supplier relationships?
Transparent communication via whistleblowing systems can strengthen trust in reputable suppliers. At the same time, problematic partners are deterred. Integration into existing supplier evaluations and the inclusion of corresponding clauses in contracts is important.
