This case study shows how one of the largest U.S. credit unions used Varonis to get control of its sensitive data and dramatically reduce data-loss risk. The organization initially struggled to find and classify PII/PCI, limit access, remove stale data, meet CCPA requirements, and detect threats. With Varonis, they gained full visibility into where data lives, who can access it, and how it’s used; automated classification and permissions cleanup; least-privilege access; and continuous monitoring that detects abnormal behavior and potential ransomware. The platform also streamlines compliance and DSARs. Within a year, the credit union cut open access by 93%, uncovered five times more stale data than expected, and safely remediated it—while Varonis helped investigate multiple alerts. Overall, Varonis reduced risk, simplified governance, and gave leadership confidence in their data security posture.
