Proliferating IoT devices across enterprise networks often go unmanaged, unmonitored, and invisible, creating blind spots that expand attack surfaces and elevate risks. ForeScout software's Zero Trust Assurance resolves this by providing continuous, agentless visibility, classification, and control for all IT, OT, IoT, and IoMT devices in heterogeneous environments. Using over 20 passive/active discovery techniques, it builds dynamic asset inventories with contextual data, assesses risk postures, detects vulnerabilities, and enforces segmentation policies—ensuring Zero Trust principles without disrupting operations and dramatically reducing enterprise-wide exposure.
