Heidi Waem is a data protection and privacy lawyer with almost 15 years’ experience advising clients in the FMCG, technology, media, life sciences, financial and public sector on all aspects of EU regulatory data protection compliance (including cybersecurity) and assisting them in data protection and privacy litigation before the Belgian Data Protection Authority and the regular courts.
