Enhancing OT Visibility: Understanding the Time and Place for Active Collection

Passive monitoring is foundational in operational technology (OT) environments but often falls short in segmented, low-traffic, or legacy systems. This whitepaper introduces how Dragos Active Collection—enabled by the Dragos Agent—helps close visibility gaps by actively querying assets to uncover additional asset information such as firmware details, patch levels, and module relationships.

Through real world examples, the paper outlines when and how to apply active collection as a complementary technique to passive collection enabling deep enrichment of asset inventories and supporting more effective vulnerability management.
