Case Study: Cigna achieves secure, governed access to its data lake and becomes more data-driven with Looker

Cigna - Customer Case Study

Cigna, a global health insurance provider offering medical, dental, supplemental and Medicare plans, faced the challenge of modernizing a decades-old data stack while meeting complex regulatory and security requirements. Leadership sought to “humanize” their data lake—making large datasets accessible and useful—without sacrificing strict, governed permissions across business units.

By deploying Looker, Cigna gave teams secure, governed access to the entire data lake (on-premise or in the cloud), enabling users to ask and answer their own questions and incorporate fresher data into workflows. The result: broader adoption of live dashboards, stronger data-driven decision-making across the company, and a consistent, compliant single source of truth.
