Case Study: a large not-for-profit organization regains control of data risks with Grant Thornton and Microsoft Purview

Large Not-for-Profit Organization secures 780 SharePoint sites with Grant Thornton LLP

The customer, a large not-for-profit organization, faced significant data exposure risks due to disconnected cybersecurity solutions and a lean IT staff. This lack of a unified security view prompted a CEO-mandated remediation. Grant Thornton was engaged to help the organization reduce its data exposure and regain executive confidence, focusing on the Microsoft Purview platform.

Grant Thornton implemented a structured solution that included a Microsoft Purview maturity assessment, baselining all 14 of its solutions. The team defined eight sensitive data categories, brought 780 SharePoint sites under sensitivity governance, and deployed automated detection and labeling capabilities. As a result, the organization established a scalable, repeatable security model that met the CEO's mandate and provided a stronger foundation for future AI initiatives.
