From Data Visibility to Control: Securing Sensitive Information Across a Hybrid School Environment

Turning dispersed data into governed, usable insight

To enable comprehensive visibility, One51 implemented Microsoft Purview Data Map across their hybrid environment, spanning both on-premises and cloud data sources. This provided the foundation for consistent discovery and classification at scale. Custom classification rules were developed specifically for their environment. To transform discovery into operational value, assets were organised into a structured hierarchy aligned to the school’s three core domains. This structure enabled data owners to directly manage their own domains, distributing accountability without compromising control. The engagement concluded with a prioritised 12-month data security roadmap, carefully sequenced and effort-sized to give the school a clear path forward without requiring re-scoping or further discovery cycles.  The school now has a complete, searchable inventory of sensitive data across its hybrid environment, including clear identification of high-risk assets containing concentrations of personal and sensitive information.
