OT Security
Assess and defend industrial control systems, SCADA, and connected equipment without disrupting production.
OT asset discovery
Passive discovery maps every PLC, HMI, and network path so you know what is on the plant floor and how it is reachable.
ICS/SCADA assessment
Safe, production-aware testing of control networks, protocols, and remote access against IEC 62443 and NIST guidance.
Segmentation & monitoring
We design zones and conduits, harden IT/OT boundaries, and add monitoring that understands industrial protocols.
What is OT Security?
Operational technology security protects the systems that run physical processes: manufacturing lines, utilities, energy, and building control. These environments run legacy equipment, cannot tolerate downtime, and are increasingly connected to IT and the internet.
NodeRisk assesses OT environments with methods designed for fragile systems, prioritizes risk by safety and production impact, and builds a defense program aligned to IEC 62443.
- Get a complete inventory of connected industrial assets
- Find unsafe remote access and flat networks
- Reduce risk without unplanned downtime
- Align with IEC 62443 and NIST 800-82
- Detect threats that target industrial protocols
How Do We Deliver OT Security?
“Their red team reached our research systems in under two weeks, and not one alert fired. Instead of a scare, we got a timeline, tuned detections, and a retest that proved the path was closed. It is the only offensive security work I have put in front of our board.”
Trusted outcomes.
Complete asset visibility
Know every device, firmware version, and connection on the plant floor.
Safer remote access
Close vendor backdoors and enforce controlled access to control systems.
Resilient segmentation
Zones and conduits that contain incidents before they reach production.
Standards alignment
Evidence and roadmaps mapped to IEC 62443 and NIST 800-82.
Industrial threat detection
Monitoring that understands Modbus, DNP3, and other OT protocols.
Protected uptime
Security improvements delivered without unplanned outages.
