Case Study: Dunn Lumber achieves faster security-incident resolution and improved PCI‑DSS compliance with Rubrik Sonar

Dunn Lumber Reduces Time to Resolve Security Incidents and Improves PCI-DSS Compliance with Rubrik Sonar

Dunn Lumber, a family-owned retail supplier serving the Greater Seattle area with nine locations and over 400 employees, faced critical data governance challenges around protecting customer financial information and meeting PCI‑DSS requirements. Manual, time-consuming data discovery left blind spots on sensitive, human-generated files stored internally—risks that were highlighted when employees received fraudulent unemployment notices during COVID‑19 and the team needed to quickly determine whether a breach had occurred.

Using Rubrik Sonar, Dunn Lumber ran rapid, custom scans and audited file access to pinpoint the root cause—narrowing the search to a single document and resolving the investigation in about a week and a half. Sonar also uncovered credit card data in unauthorized locations and thousands of removable documents, enabling quick remediation, reduced PCI‑DSS exposure, lower cyber insurance premiums, and streamlined audits—all with no production impact and a setup time under 30 minutes.
