Case Study: T-Mobile achieves enterprise-scale data protection and cost savings with Ataccama ONE

T-Mobile saves $350 million with Ataccama

T-Mobile, a leading US mobile and 5G carrier, faced the challenge of securing vast amounts of customer data, maintaining regulatory compliance, and reducing costs following a significant data breach. To achieve an enterprise-wide data transformation, they turned to their long-time partner, Ataccama, and implemented its unified data management platform, Ataccama ONE.

Ataccama's solution enabled T-Mobile to launch a "Data Scanning at Scale" initiative that automated data quality and classification across its complex infrastructure. The results were substantial, including $350 million in cost-avoidance from preventing PII leakage, $50 million saved by removing redundant systems, and $25 million saved by reducing data preparation times for AI teams. This partnership with Ataccama strengthened T-Mobile's data security and provided a significant competitive advantage.
