GDPR & data
GDPR and data protection lawyer in Luxembourg
The firm guides your GDPR compliance: records of processing activities, privacy policies, data processing agreements (DPAs) and dealings with the CNPD.
Legal content reviewed by Maître Cora Maglo, Avocate à la Cour, Liste I du Barreau de Luxembourg depuis 2009.
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.
The need
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.
The risk
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 the firm helps
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.

What our clients say
Had a consultation with Me Cora Maglo about my Luxembourg Blue Card application. She explained everything clearly: the process, timeline and documents I need, and helped me with my wife’s family reunification too. Honest and practical advice. I felt confident after talking to her.Farshid Pourlatifi
J’ai beaucoup apprécié le service de Maître Maglo : son sérieux, sa sympathie, son professionnalisme et sa disponibilité. Toujours répondu rapidement et clairement, avec des conseils pragmatiques, sans pousser à des procédures longues et coûteuses lorsqu’elles ne sont pas justifiées.Nathan Wirtzfeld
Super assistance and great support! Highly recommend. All my questions were answered, Cora and her team kept me updated all the time. I will definitely reach out to them next time for my residency.Tatiana
