Only 13% of OT Network Segments Are Fully Isolated: Analysis
Forescout finds only 13% of OT-containing network segments are fully isolated across 209 organizations.
Forescout Vedere Labs examined 47,700 network segments and more than 2.5 million devices across 209 organizations, labeling devices IT, OT, IoT, or IoMT. Although 62% of segments held one category, only 13% of segments with an OT device were OT-only, and only 6% of medical-device segments were IoMT-only. IP cameras appeared in 2,266 segments, about 2% of them camera-only, and the average segment held 54 devices of four types. The largest average blast radii were in business services, healthcare, and oil and gas; only about 20% of retail POS segments were POS-only.
