Written by TrustArray | Aug 8, 2025 12:27:30 PM

The Challenge:

A major Canadian telecom company came to Array seeking help after a cybersecurity breach exposed both employee and customer data on the “dark web.” Array assisted by reviewing and reporting on 145,000 compromised PII documents, identifying what information was breached, who it belonged to, and whether the individuals were customers or employees. Conducting this review in-house or through external counsel would have been both costly and extremely time-consuming.

The Solution:

Array implemented a complex, technology-based workflow leveraging automation to efficiently handle the large volume of compromised PII documents.
