Client challenge
Our client needed to analyse a backup of all data connected with an individual involved in a high-profile international fraud case. This data included hard drive of forensic images, images of email servers and even backup tapes – in all, almost 10 TB of data spanning the past decade.
The client had to find any evidence of wrongdoing and deliver it for legal review before producing it for a court. It would have been impossible and cost prohibitive to conduct traditional linear review of these masses of evidence.
The solution
The advisory engaged Grant Thornton’s Cyber-eDiscovery Resilience Team to provide a cost-effective solution for dealing with this much data to find relevant evidence sooner. The volume of data made an on-premise solution unviable, so we used Nuix Discover, an ISO 27001-certified cloud platform, to conduct an early case assessment of the data.
Applying culling techniques such as deduplication, keyword searches, concept analysis, social network analysis and date range filters helped the advisory defensibly eliminate the vast majority of data that was not relevant to the case.
The outcome
Within two months, the early case assessment had culled the data set from 12 million items to just 942,000. This eliminated 92 per cent of items from needing to be hosted in a review platform and examined by lawyers, achieving a substantial cost and time saving for the client.
