The latest decision by the President of the Personal Data Protection Office (PUODO), imposing a fine of over PLN 11 million on DPD Polska, once again highlights one of the fundamental, yet often overlooked, elements of the personal data protection system: the proper regulation of the relationship between the data controller and the processor. This case demonstrates that the lack of a properly concluded personal data processing agreement is not merely a formal infringement but can constitute a serious violation of the GDPR.

What will you learn from this article?


  • What is a data processing agreement under Article 28 of the GDPR and what elements must it contain for it to be considered effective?
  • Why is the chain of subcontractors (carriers, IT, marketing) the biggest challenge for maintaining the principle of accountability?
  • What is processor due diligence and why does a controller have an obligation to verify its business partners?
  • What specific steps should an entrepreneur take to avoid the errors identified in the supervisory authority's decision?

Data processing agreement

Entrusting data as a basis for legal processing by an external entity


According to Article 28 of the GDPR, a data controller may only use the services of a data processor if the processing is based on a contract or other legal instrument binding the parties. This document specifies, among other things, the subject matter and duration of processing, the nature and purpose of data processing, the type of personal data, and the categories of data subjects.

The purpose of a personal data processing agreement is to ensure the controller has real control over how the external entity processes data. In practice, this means precisely defining the processor's responsibilities, including the use of appropriate technical and organizational measures, rules for engaging subcontractors, and the obligation to support the controller in exercising the rights of data subjects.

The systemic problem with subcontractor-based models


In every industry, it is easy to encounter situations where multiple entities involved in providing a service gain access to personal data. In practice, these may include carriers, IT specialists, marketing agencies, warehouse operators, and delivery companies.

The PUODO's decision indicates that failure to properly regulate these relationships - especially in the case of a broad network of operational partners - may lead to a violation of the accountability principle set out in Article 5(2) of the GDPR. The controller remains responsible for demonstrating that personal data are processed in accordance with the regulations, regardless of the number of subcontractors involved in the process.

Entrustment agreement as an element of risk management


From a compliance and risk management perspective, a data processing agreement serves as a control tool. It should not only formally regulate data processing but also reflect actual business processes. This requires prior identification of all entities with access to data and an assessment of the scope of processing performed by each.

Processor due diligence - are also gaining increasing importance. A controller should be able to verify whether a given entity meets GDPR information security requirements and has appropriate organizational and technical measures in place.

Conclusions for entrepreneurs


The PUODO's decision serves as an important reminder that proper regulation of relationships with external entities is crucial in the personal data protection system. In practice, this means the need to:

  • identification of all processors having access to personal data,
  • concluding data processing agreements in accordance with the requirements of Article 28 of the GDPR,
  • monitoring how these agreements are implemented in practice,
  • ensuring control over any further sub-entrustment of data.

The DPD case demonstrates that the supervisory authority is increasingly focusing not only on security incidents but also on the proper organization of data processing processes. As a result, a properly constructed and implemented data processing agreement is becoming one of the fundamental tools for mitigating legal risk in business operations.
