GenAI Is Exposing Sensitive Data At Scale
Help Net Security, Thursday, September 25th, 2025
Sensitive data is everywhere and growing fast. A new report from Concentric AI highlights how unstructured data, duplicate files, and risky sharing practices are creating serious problems for security teams.
The findings show how generative AI tools like Microsoft Copilot are adding complexity, while old problems like oversharing and poor data hygiene continue to create exposure.
Generative AI raises new concerns
On average, Copilot accessed nearly three million sensitive data records per organization during the first half of 2025. Researchers also found more than 3,000 user interactions per organization with Copilot, which means more chances for sensitive data to be modified or shared without proper controls.
