White Paper: Tackling Complex Data Subject Access Requests (DSARs)
A practical guide to managing complex DSARs at scale with the right processes and tools
DSARs become complex when they move beyond a simple ‘locate and disclose’ exercise, turning into a multi-step judgement process across systems and data types.
Without the right approach, complex DSARs can quickly become resource-intensive, putting pressure on internal teams and increasing the risk of errors or wrongful disclosure.
Use this guide to:
- Apply a structured approach to managing large or complex DSARs
- Reduce the time and effort required to locate, review, and prepare data
- Improve consistency when handling redaction, confidentiality, and disclosure decisions

What you’ll find inside
This guide brings together the expertise of two leading data protection compliance providers.
It explores the key challenges organisations face when handling complex DSARs, including large data volumes, multiple data sources, and third-party or confidential information.
You’ll learn practical ways to address these challenges through improved internal processes, such as data mapping, retention practices, and structured workflows.
The guide also highlights how technology can support DSAR handling, with tools to help identify, filter, review, and redact data more efficiently.
