Latest news & insights:

Organisations are seeing a steep rise in the number of individuals using data subject access requests (DSARs) to obtain a copy of their personal data – a 66% increase in the average number of DSARs was recorded by the UK Data Protection Index between 2020 and 2021.

With strict time limits for responding, as well as organisations now holding large volumes of complex data often spread over poorly integrated systems, this is creating a significant challenge in maintaining compliance with data protection legislation.

How our DSAR support service can help

To respond to the growing challenges surrounding DSARs, we have developed our DSAR support service, which combines technology, artificial intelligence (AI) and legal expertise to help you deal with DSARs efficiently, accurately and cost effectively.

The benefits

  • Cost certainty - manually reviewing documents is both expensive and unpredictable. By using our AI facilitated workflows we are able to provide reliable indicators of pricing based on volume at an early stage.
  • Improved accuracy and efficiency – our tailored processes and workflows reduce the need for manual reviews of data, ensuring a streamlined approach to handling a DSAR.
  • Technology backed by legal experts – combining our extensive data protection expertise with a leading artificial intelligence platform enables us to provide a solution tailored to your needs.


Our AI facilitated review deploys data deduplication across multiple data sources for our clients, enabling us to remove duplicates, even where they are stored in separate locations. Email threading allows us to organise and group email conversations together to avoid further duplication.

Moving beyond the AI facilitated review of documents, our legal teams use defensible search techniques to reduce document review volumes while still complying with the data subject’s access rights.

Combining our legal expertise with our AI technology, we were recently able to reduce an initial review by 98%, from 300,000 documents to just under 6,000, saving considerable resource and expense and without compromising our client’s obligations’ to the data subject.
