GDPR and its impact on Luxembourg companies

10 min

What is GDPR?

GDPR
The General Data Protection Regulation (GDPR) is an EU law on the protection of individuals with regard to the processing of their personal data and the free movement of such data within the European Union. This law marked a turning point in the protection of privacy and digital rights in Europe, it constitutes the most robust European regulatory framework on privacy and its main objective is to give citizens back control over their personal data while facilitating a consistent regulatory environment for companies operating in Europe.

The European Parliament finally adopted this Regulation on April 27, 2016 after four years of legislative negotiations and its provisions are directly applicable in all EU Member States as of May 25, 2018.

The GDPR regulation establishes the following rights for all individuals, regardless of whether or not they are citizens of the European Union:

  • Right of access: allows individuals to know what personal data is being processed, by whom and for what purpose.
  • Right of rectification: ensures that individuals can correct inaccurate or incomplete data.
  • Right to erasure (right to be forgotten): grants the possibility to request the deletion of personal data in certain circumstances.
  • Right to data portability: makes it possible to transfer personal data from one entity to another in a structured and commonly used format.
  • Right to object: allows individuals to object to data processing in specific situations such as direct marketing.
  • Right to limitation of processing: temporarily restricts the use of certain data.
  • Right to automated decision-making: protects against decisions based solely on automated processing including profiling.

Furthermore, the GDPR is not limited to European companies, it covers any organization that processes personal data of European citizens. This means that the GDPR also affects organizations outside the EU if they process data related to offering goods or services to individuals in the EU or monitor the behavior of individuals within the EU, such as through cookies or analytics tools.

Luxembourg: a financial and digital hub under GDPR

As the GDPR is a Regulation and not a Directive, it is directly binding and enforceable and does not provide flexibility for Member States to adjust certain aspects of the Law. However, each state has the option to adopt national laws to transpose the new provisions of the GDPR into national law. So to incorporate in the country the GDPR law Luxembourg did exactly this through the law of August 1, 2018, which entered into force on August 20, 2018.

CNPD
The Commission Nationale pour la Protection des Données (CNPD) is the entity in charge of monitoring and enforcing GDPR in Luxembourg. Within its functions is to investigate possible breaches of the GDPR, provide guidance to companies on their legal obligations, assess the compliance of data processing processes through audits, collaborate with other national and international authorities in cross-border cases and, when necessary, impose sanctions on companies.

GDPR Obligations and impact on Luxembourgish companies

Luxembourg has established itself as one of the leading financial and technology centers in Europe and the world and is home to a large number of companies, from innovative startups to large corporations. Many of these companies, especially in sectors such as finance and digital services, handle a high volume of personal data. The GDPR regulation then has a huge impact on all these companies who are subject to a large number of obligations in order to operate in compliance with the law. Below we will look then at the main obligations to which they are subject.

Respecting the basic principles of data processing

Companies in Luxembourg must respect the core principles of the GDPR when processing personal data:

  • Lawfulness, fairness and transparency: it must be ensured that data processing has a lawful basis and is transparent and comprehensible to data subjects.
  • Purpose limitation: data may only be collected for specified, explicit and legitimate purposes and must not be processed in a way incompatible with those purposes.
  • Data minimization: only personal data strictly necessary to fulfill the purposes of the processing must be collected.
  • Accuracy: personal data must be kept up to date, and inaccurate personal data must be corrected or deleted.
  • Storage limitation: data should be kept only for the time necessary for the stated purposes.
  • Integrity and confidentiality: data must be protected against unauthorized access, loss, alteration or destruction by technical and organizational security measures.
  • Proactive accountability: compliance with GDPR obligations must be demonstrated through records, internal policies and appropriate documentation.

Legal basis for data processing

Before processing personal data companies must identify a valid legal basis under the GDPR that allows them to do so. This may include explicit consent from data subjects, signed contracts, compliance with legal obligations or legitimate business interests, provided these do not infringe on individual rights. Consent must be given in a free, informed and verifiable manner, which means that companies cannot assume tacit consent or use ambiguous documents to obtain it.

Recording of processing activities

Organizations are required to keep an internal register documenting all their data processing activities. This log must include the purposes of the processing, the categories of data processed, the data retention period as well as the security measures implemented.

Appointment of a Data Protection Officer (DPO)

When data processing involves high risks such as systematic or large-scale monitoring of sensitive data companies must appoint a Data Protection Officer (DPO) who must oversee GDPR compliance and advise the company. Although not all companies require a DPO many choose to appoint one voluntarily to ensure proper management.

Data Protection Impact Assessments (DPIAs)

If processing activities represent a high risk to the rights and freedoms of data subjects, companies must conduct a Data Protection Impact Assessment (DPIA). This study should make it possible to analyze the associated risks and establish measures to mitigate them and if they cannot minimize the risk, they should consult with the CNPD before proceeding.

Security breach notification

In the event of a security breach affecting personal data, companies must notify the CNPD within 72 hours and if the incident generates a significant risk to the rights of data subjects they must also inform them directly.

Data subjects' rights

Organizations must enable mechanisms for individuals to exercise their rights to access, rectification, erasure, portability and objection to the processing of their data. In addition, the controller is obliged to respond to the data subject's requests without undue delay and, at the latest, within one month.

Security measures

The GDPR requires the implementation of technical and organizational measures to safeguard data. This includes encryption, access control, anonymization policies and formation on the GDPR in Luxembourg for the organization's staff. These measures must be adapted to the level of risk associated with the processing and demonstrate the company's commitment to data protection.

International data transfers

When transferring personal data outside the European Union, companies must ensure that the receiving country provides an adequate level of protection.

Fines and sanctions

The GDPR establishes a severe sanctions regime to ensure compliance. The main sanctions are as follows:

Financial fines

These fines can be more or less significant depending on the seriousness of the misconduct and fall into two categories:
Fines of up to 10 million euros or 2% of the global annual turnover, whichever is higher, for violations considered less serious such as may be for example the failure to properly maintain the register of processing activities or the failure to appoint a Data Protection Officer (DPO) when mandatory.Fines of up to 20 million euros or 4% of the global annual turnover, whichever is higher, for serious violations that directly affect the rights and freedoms of data subjects. For example refusing access to or deletion of data or unlawful international transfers of personal data to countries outside the EU without the necessary safeguards.

Corrective measures

In addition to financial fines GDPR empowers supervisory authorities which in Luxembourg, is the CNPD to impose non-monetary corrective measures such as:

  • Periodic data protection audits.
  • Orders to cease the processing of data that do not comply with the GDPR.
  • Temporary or definitive restrictions on the use of personal data.
  • Prohibition of specific activities related to data processing.
  • Requests for rectification or deletion of personal data that has been unlawfully processed.
  • Requests for improvements in security and data collection practices.

An example of the enforcement of these fines took place in 2021 when the National Commission for Data Protection imposed a record fine of 746 million euros on Amazon Europe Core for failing to respect EU data protection. This was the largest penalty ever imposed under these rules.
