From 17,000 to 1.1 Million Assets: How Lumen Technologies Rebuilt Exposure Management at Scale

Lumen Technologies dramatically improved its exposure management program by reconciling data from over 40 disconnected systems, revealing a massive underestimation of its cyber assets – growing from approximately 17,000 to 1.1 million devices. Leveraging the Axonius asset intelligence platform, Lumen shifted from a ‘scan and spam’ approach to a risk-based exposure management strategy, leading to a 40% reduction in risk and a significant increase in security investment and board-level reporting. The company’s experience highlights a common issue across many organizations: inaccurate asset inventories leading to flawed security practices.
