Case Study: a Fortune 500 financial services firm right-sizes access to confidential data with Oleria

Fortune 500 financial services firm right-sizes access with Oleria, cutting 50,000 users to 50 active

A Fortune 500 financial services firm faced significant access governance challenges. With a workforce of over 30,000, the company had 50,000 users with standing access to confidential data, yet only 50 had actually used it. Their security team struggled with manual, script-heavy processes to monitor leavers and understand data exposure across more than 25,000 SharePoint sites, consuming 1.5 FTEs of engineering time. They turned to Oleria for a usage-aware access governance solution to address these issues under strict regulatory oversight.

Oleria implemented its Access Knowledge Graph across the firm's Microsoft Entra ID, SharePoint Online, and Salesforce environments. This solution mapped all permissions and paired them with real user activity, providing clear visibility into access and usage. As a result, the firm automated leaver monitoring, enabled evidence-based access reviews for managers, and quantified data exposure. Oleria's deployment directly reclaimed 1.5 FTEs of engineering capacity and provided continuous governance to meet regulatory requirements.
