Case Study: Regional Telecom Provider achieves enterprise-wide cloud security and reduced identity risk with Tenable Networks

Regional Telecom Provider standardizes on Tenable for CIEM and CNAPP enterprise-wide

A large regional telecommunications provider accelerating a migration from on‑premises to a full cloud environment (AWS and Azure) faced a security challenge: after restarting a pandemic‑delayed transformation, the cloud governance team needed multicloud visibility and stronger identity risk management. Although the company had standardized on CSPM for compliance reporting, they determined CSPM alone would not surface IAM risks and began evaluating CIEM solutions to address permissions and identity exposure.

Following a demo and proof of concept, the provider selected Tenable for its identity‑first approach and high accuracy, quickly rolling it out in two groups with plans to standardize enterprise‑wide. Teams now use Tenable’s CIEM and policy‑based alerting to reduce excessive permissions, enforce least privilege, detect anomalies, save time prioritizing risks, and are moving toward Just‑in‑Time access controls while evaluating Tenable for full CNAPP adoption.
