Bottom line: Incomplete asset visibility is a security risk; Lumen Technologies discovered 64 times more assets after a review than previously recorded, revealing an industry-wide blindness to actual managed infrastructure.
Lumen Technologies has fundamentally overhauled its asset management and exposure visibility, increasing the number of known assets from 17,000 to 1.1 million. This illustrates a fundamental IT security problem: only 45 percent of enterprises consolidate their asset and exposure data in a single view.
According to the 2026 Actionability Report by Axonius, based on a survey of over 600 security leaders, there is widespread confidence in flawed asset inventories. Companies assume their inventories are sufficiently accurate – reality contradicts this. Every downstream security program inherits the deficiencies of the inventory and can only operate on the basis of this incomplete or fragmented data.
The Lumen Technologies case demonstrates how massive this gap can be: the company had originally recorded only 17,000 assets. After a structured overhaul of its asset management and exposure management processes, it was able to grow the known asset population to 1.1 million. This figure illustrates how many resources – servers, endpoints, cloud instances, network devices – in large organizations escape visibility.
This leads chief information security officers to a critical insight: fragmented or incomplete asset visibility is a fundamental security risk. Unknown or misclassified assets cannot be configured, patched, or monitored. They create “blind spots” that attackers can exploit. Building a consolidated, reliable asset view is therefore not optional, but fundamental to any effective security program.
Lumen demonstrates that comprehensive asset inventory with appropriate tooling and process harmonization is possible – but requires significant organizational effort. For other enterprises, the lesson is clear: regular review and consolidation of asset data sources is not discretionary, but a permanent, critical governance issue.
