This case study details the challenges faced by a large public healthcare organization in the United Kingdom, specifically an NHS Trust, regarding data security and compliance with GDPR. The Trust encountered significant issues with excessive user permissions that led to accidental deletions of sensitive data. The internal investigation revealed a lack of visibility into user access and behavior, which posed a risk for potential data breaches. To address these challenges, the Trust implemented the Lepide Data Security Platform, which provided real-time visibility, privileged user monitoring, and compliance reporting. The platform enabled the IT team to audit changes across various systems and detect anomalous user behavior, allowing for immediate action to prevent breaches. Additionally, it facilitated the identification and removal of excessive permissions, supporting a least privilege model and improving compliance with GDPR requirements. The case study highlights the operational efficiency gained through automated reporting and reduced manual efforts in managing access controls.
