Cyber-Physical Security covers the tools that protect the systems where software meets the physical world: operational technology, industrial control systems, IoT and embedded devices, and the critical infrastructure they run. You reach for it once your risk surface stops being data and starts being a turbine, a PLC, a building automation controller, or an infusion pump, where the wrong packet can halt a process line or hurt someone. The space breaks into distinct problems. OT Asset Discovery and OT Network Segmentation give you the inventory and the boundaries that IT tooling cannot, because an IT scanner would crash a fragile controller on contact. Industrial Control System Security, SCADA Security, and OT Vulnerability Management handle plant-floor protocols and the patch-cycle reality of equipment that runs for twenty years. CPS Protection frames the broader cross-domain risk, while IoT Security, Firmware and Embedded Security, and Medical Device Security each address a fleet of connected devices with their own constraints. Most security leaders assemble coverage across several of these, because the OT environment, the connected-device estate, and the firmware supply chain rarely answer to one platform.

Common questions about Cyber-Physical Security tools, selection guides, pricing, and comparisons.
Cyber-Physical Security is the practice and tooling for protecting systems where software controls physical processes: operational technology, industrial control systems, SCADA, IoT and embedded devices, and the critical infrastructure they run. It covers asset discovery, network segmentation, vulnerability management, and firmware analysis for equipment that traditional IT security cannot safely touch. The aim is to keep these environments visible, monitored, and resilient without disrupting the process they control.
IT security optimizes for confidentiality and can patch and reboot on a schedule. Cyber-physical systems optimize for availability and safety, run for decades on fragile protocols, and often cannot be patched or actively scanned without risking the process. The stakes shift from data loss to physical harm and downtime, which is why this category leans on passive monitoring, segmentation, and compensating controls rather than the agent-and-scan model IT tools assume.
Start with visibility. OT Asset Discovery tells you what is actually on the network, which nearly every program finds is more than the documentation claims. From there, OT Network Segmentation and ICS or SCADA Security let you contain and monitor the environment, while OT Vulnerability Management prioritizes what little you can realistically fix. If your exposure is a connected-device estate or medical equipment, IoT Security and Medical Device Security come first instead.
IoT Security is one subcategory inside the broader cyber-physical space, focused on the connected-device estate: cameras, sensors, building systems, and consumer-grade gear bridging into the network. Cyber-Physical Security also spans industrial control and SCADA on the plant floor, firmware and embedded analysis at the chip and bootloader level, and medical devices in clinical settings. The threats and constraints differ enough that most teams need coverage across several, not a single IoT tool.
Your IT stack covers the corporate network around these systems but not the systems themselves. Endpoint agents will not install on a PLC, IT vulnerability scanners can crash a controller, and your SIEM does not parse industrial protocols. Dedicated cyber-physical tooling fills that gap with passive discovery, protocol-aware monitoring, and OT-safe vulnerability management, then feeds the results back into the SOC workflow you already run.
