Case Study: Delta Dental of Missouri achieves HIPAA‑compliant, invisible data encryption with Thales Vormetric Data Security Platform

Thales helps delta dental of missouri be a good ombudsman of patients

Delta Dental of Missouri, part of the Delta Dental network and carrier for over 2,000 companies, manages terabytes of sensitive member and claims data and needed to meet HIPAA requirements for data in transit and at rest. Database-level encryption options threatened major application rewrites, user disruption and heavy operational overhead, so the organization sought a policy-based, platform-agnostic solution with centralized key management, transparent encryption and minimal performance impact — ultimately engaging Thales and its Vormetric Data Security Platform.

Thales deployed the Vormetric Data Security Platform (including Vormetric Transparent Data Encryption and the Vormetric Data Security Manager) via a staged, low-effort rollout and file-level encryption; the implementation avoided costly application rewrites, saved “at least nine months” of development effort, and required minimal ongoing administration. The solution delivered near-zero user-visible performance overhead, built-in high-availability/failover, simpler backups, and helped Delta Dental of Missouri achieve HIPAA-aligned protection and a scalable, “set-and-forget” encryption posture.
