Supervisory Authority Inspection Preparation
Overview
Supervisory authorities (Data Protection Authorities, or DPAs) exercise investigative powers under Art. 58(1) GDPR, including the power to order controllers and processors to provide any information required for the performance of their tasks (Art. 58(1)(a)), to carry out investigations in the form of data protection audits (Art. 58(1)(b)), to carry out a review on certifications (Art. 58(1)(c)), to notify the controller or processor of an alleged infringement (Art. 58(1)(d)), to obtain access to all personal data and information necessary (Art. 58(1)(e)), and to obtain access to any premises of the controller and processor, including data processing equipment (Art. 58(1)(f)).
DPA inspections may be triggered by data subject complaints, sector-wide enforcement campaigns, data breach notifications, random selection, media reports, or whistleblower reports. The consequences of inadequate inspection performance include corrective measures under Art. 58(2), administrative fines under Art. 83, and reputational damage through enforcement action publicity.
Sentinel Compliance Group maintains a standing DPA inspection readiness program that ensures the organization can respond effectively to announced and unannounced supervisory authority contact within defined timeframes.
