European Law Firm Achieves Massive Data Reduction

A European law firm faced an immense regulatory challenge: their client needed to review and produce data from a starting universe of over 100TB. With strict deadlines and cost concerns, the firm turned to Sandline to rapidly reduce, review, and produce the necessary data while maintaining compliance.
100TB
Initial dataset reduced to a manageable review corpus
97%
Reduction in data volume through forensic culling
30%
Cost savings achieved while meeting all review targets

The Challenge

The client’s data—initially stored as Veeam backups and later received in .PST format—posed a monumental volume problem. They needed a targeted and defensible approach to drastically cull the data while ensuring regulatory requirements were met. The review had to be completed in an extremely short timeframe.

Expertise

Sandline’s forensic culling process eliminated 97% of the original dataset, reducing 100TB down to just 2GB of responsive data for final review. Key steps included:

  • Forensically culling 2.4TB before ingestion
  • Processing 1.57TB of relevant data
  • Further reducing post-processing data from 3TB to just 2GB of responsive content
  • Implementing customized workflows to streamline compliance

Throughout the project, Sandline worked closely with the law firm to ensure strategic decision-making, leveraging technology and expertise to maximize efficiency without compromising accuracy.

Results

By combining advanced data reduction techniques with precision workflows, Sandline enabled the law firm to meet their regulatory obligations:

  • Coming in 30% under budget
  • Completing the project a full week ahead of schedule
  • Delivering a defensible, regulator-ready dataset
