U.S. Telco Giant Makes Cybersecurity Decisions 50% Faster by Quantifying the Dollar Impact of Cyber Risks

One of the U.S.’s largest telecommunications companies—serving tens of millions of customers across thousands of network points and processing over a billion threat events per day—needed clearer, business-ready answers about cyber exposure. Boards and executives wanted to know the dollar impact of breaches, whether to remediate or accept risks, and how cybersecurity investments aligned with business priorities, but inconsistent risk taxonomies and a lack of 360° visibility across internal and external systems made those decisions difficult.

The CISO implemented MetricStream Cyber Risk Quantification, using a FAIR‑based engine and API integrations with 100+ systems to generate a single, real‑time dollar‑impact risk score mapped to assets and business lines. The result: decision-making accelerated by 50%, stronger prioritization of remediation and investments, harmonized risk scoring across teams, improved oversight for the board, and a platform the company can extend to other risk domains.
