Kennedy Van der Laan manages a substantial workload encompassing data privacy, cybersecurity, and regulatory compliance mandates. The practice is led by a trio of experts: Hester de Vries, who advises public and private clients on building robust data strategies, ensuring GDPR and ePrivacy compliance; Quirine Tjeenk Willink, an administrative litigator who handles data protection enforcement, regulatory investigations, and compliance; and Rosalie Brand, who guides clients through complex cyber incidents, including ransomware, fraud, and cyber espionage. Integral to the team is Judica Krikke, who brings strong capabilities in IT law, cloud sourcing, software licensing, data protection, and digital transformation. In February 2025, the team welcomed Erik Jonkman, who has a notable specialism in cyber risk, incident response, and civil claims.
