Walter van Holst

At Hooghiemstra & Partners, Walter's work includes large and complex Data Protection Impact Assessments, such as those for the Ministry of Health, Welfare and Sport's CoronaCheck and Coronamelder apps. He advises organisations on authorisation issues so that they can protect sensitive information. He also supports organisations that cooperate with each other and wish to exchange personal data in the process. In doing so, Walter combines the legal requirements surrounding data exchange and chain computerisation with strategic stakeholder management. With his knowledge of Privacy-by-Design, he provides advice that works.

Walter is also involved in standardisation processes, NEN standards and certification. He is also involved in innovative data-driven projects in the mobility sector such as the use of data for Mobility-as-a-Service. He regularly joins BNR Digitaal as an expert.
