Challenge

An Australian law firm faced an urgent data breach matter involving a large, unstructured dataset requiring identification of PII, PHI, and high-risk financial information. Key challenges included:

• Initial ambiguity around documents related to financial applications and related products
• Tight regulatory deadlines, with significant reputational and compliance risk if reporting proved inaccurate or incomplete

The firm needed a fast, defensible way to isolate reportable records while maintaining accuracy under pressure.

Solution

Elevate’s Data Breach team executed a rapid, structured review using advanced analytics to reduce a large dataset to a defensible, reportable population within a tight timeline. This was achieved through:

• Deploying a 23-member data breach review team, led by a project manager serving as the subject matter expert
• Using RelativityOne to ingest and analyse 16 GB of data across 34,990 documents
• Applying data mining, de-duplication, email threading, and targeted search term strategies to systematically narrow the review scope
• Conducting iterative sampling and quality checks to remove non-reportable content and improving accuracy
• Refining workflows to focus on high-risk PII, PHI, and financial data categories, ensuring defensible and compliant outcomes
