Crown Castle: A Journey to Integrated GRC with the Diligent One Platform

Executive Summary

Crown Castle’s journey to integrated GRC illustrates how a major U.S. communications infrastructure provider modernized audit, risk management, internal controls, and SOX compliance by moving away from spreadsheet-driven processes and disconnected systems. With a nationwide footprint spanning towers, fiber, and small cells—and a lean workforce of approximately **4,000 employees**—Crown Castle needed greater consistency, visibility, and agility to keep pace with growing operational complexity and regulatory expectations.

By implementing the **Diligent One Platform**, Crown Castle unified its approach across risk, audit, internal control management, and SOX compliance—creating a shared foundation of workflows, data, and reporting. This integration improved accountability across functions, strengthened executive and board-level insight, reduced manual effort, and enabled a more proactive and resilient governance posture.
