What is Cyber-Physical Systems Protection (CPS Protection)?
Cyber-Physical Systems Protection (CPS Protection) is a security discipline that covers the identification, monitoring, and defense of networked systems where digital components directly control or interact with physical processes. It spans sectors including healthcare devices, building management systems, automotive networks, aviation fleets, and broad IoT and OT environments.
What it does
CPS Protection platforms secure systems where software and hardware interact with the physical world. Unlike pure IT security, a failure here can cause physical harm, equipment damage, or safety incidents. These platforms typically:
- Discover and inventory connected assets across OT, IoT, and specialized device networks
- Monitor device behavior and network traffic for anomalies
- Identify vulnerabilities in firmware, protocols, and configurations
- Detect threats such as GNSS spoofing, unauthorized commands, or lateral movement
- Enforce access controls and segmentation policies
- Support compliance reporting for sector-specific regulations
The scope is deliberately broad. A single platform may protect building automation controllers, connected vehicles, aviation ground systems, and industrial sensors under one management layer.
Why teams buy it
Organizations buy CPS Protection when their attack surface includes physical systems that standard IT security tools cannot see or safely interact with. Common drivers include:
- Regulatory pressure in healthcare, automotive, aviation, and critical infrastructure
- Incidents where an IT breach crossed into OT or physical control systems
- Lack of visibility into legacy devices that cannot run agents
- The need to correlate threats across IT, OT, and IoT in one place
CPS Protection sits within the broader Cyber-Physical Security parent category alongside more focused disciplines such as ICS Security, OT Security, and Medical Device Security.
What to look for
- Protocol support: Does the platform understand the proprietary protocols used in your sector, such as BACnet for building systems, V2X for automotive, or aviation-specific standards?
