The GDPR applies to any organisation processing personal data. In Luxembourg, the supervisory authority is the CNPD.

The firm turns a complex regulatory obligation into a clear approach, proportionate to your activity.

GDPR and data protection lawyer in Luxembourg: when should you call on the firm?

Websites, customer files, HR and marketing tools: most businesses process personal data without any formal framework.

Information notices, the record of processing and contracts with service providers are often missing.

What happens if you do nothing?

The GDPR provides for fines that can reach very high amounts, together with a reputational risk in the event of a data breach.

The absence of a legal basis or of valid information makes a processing activity unlawful.

How does the firm step in?

Mapping of your processing activities, drafting of the record of processing, privacy policies and data processing clauses, and support in the event of an inspection.

The firm prioritises actions according to your real level of risk. Our digital tools only help gather and qualify information; the legal analysis is provided by a lawyer admitted to the Luxembourg Bar.

Does my company need to comply with the GDPR?

Direct answer. Yes, as soon as you process personal data: customer files, payroll, a contact form, a newsletter or a recruitment tool. Company size does not exempt you from the GDPR; it mainly influences the documentation required and the level of formality.

The first step is to map what you collect, why, and from whom. This map then serves as the basis for the record, the information notices and the contracts with providers.

Is a record of processing activities mandatory?

Direct answer. In principle yes, but Article 30 of the GDPR provides an exemption for organisations with fewer than 250 people. The exemption falls away if the processing is not occasional, poses a risk to people's rights, or concerns sensitive data. In practice, most companies keep a record.

An up-to-date record is also the first document the CNPD asks for during an inspection.

What should you do in the event of a data breach?

Direct answer. Document the incident immediately and, unless the breach is unlikely to result in a risk to people, notify the CNPD within 72 hours of becoming aware of it. If the risk is high, the people concerned must also be informed.

The firm prepares an internal procedure before any incident, with roles and notification templates, so that the deadline can be met.

Is a DPO mandatory for my company?

Direct answer. A data protection officer is mandatory only in specific cases under Article 37: a public authority, regular and systematic large-scale monitoring of individuals, or large-scale processing of sensitive data. An ordinary SME is generally not required to appoint one, but may do so voluntarily.

The firm reviews your activity and tells you in writing whether appointment is required.

FAQ

Frequently asked questions

Does the GDPR apply to my small business?

Yes, the GDPR applies to your small business as soon as you process personal data (customers, employees, prospects), whatever your size.

Do I need to appoint a DPO?

Appointing a data protection officer is only mandatory in certain cases. The firm tells you whether a DPO is required for your organisation.

Who enforces the GDPR in Luxembourg?

The GDPR is enforced in Luxembourg by the Commission nationale pour la protection des donnees (CNPD), the competent supervisory authority.

What fine does a company face for GDPR non-compliance?

The fine can reach EUR 20 million or 4% of worldwide annual turnover for the most serious breaches, and EUR 10 million or 2% for other obligations. The amount depends on the gravity, the duration and the company's cooperation.

How long do I have to reply to a data access request?

One month from receipt of the request, extendable by two months if complex, with the person informed within the first month.
