Case Study: London Borough of Barking and Dagenham secures residents' data and streamlines privacy management with OneTrust

London Borough of Barking and Dagenham Provides Vital Governmental Services and Protects Resident’s Data with OneTrust

London Borough of Barking and Dagenham, the local government for an East London borough serving about 200,000 residents, faced the challenge of protecting large volumes of sensitive citizen data while lacking capacity and centralized oversight across roughly 3,500 employees. To replace inefficient Excel-based processes and meet GDPR obligations, the borough selected OneTrust and deployed a broad set of its privacy products, including Assessment Automation, Data Mapping Automation, Consent and Preference Management, Cookie Consent and Website Scanning, Data Subject Rights Management, and Incident and Breach Response.

Using OneTrust, Barking and Dagenham implemented a “privacy champions” model and centralized privacy work in a single dashboard, enabling automated DPIAs, a complete data asset register, granular cookie and consent management, and self-service incident reporting. The result was faster, more consistent handling of high‑risk projects, devolved breach reporting to staff across the authority, and demonstrable GDPR controls for citizens—converting fragmented Excel processes into an auditable, organization-wide privacy program powered by OneTrust.
