nNetNDR is a self-hosted security product for monitoring industrial control system and operational technology networks.
What nNetNDR is
nNetNDR is a self-hosted security product for monitoring industrial control system and operational technology networks. It passively analyzes mirrored traffic to identify OT assets, communication flows, protocols, threats, vulnerabilities, and security risks without disrupting operations. Detection combines ICS-specific whitelisting, signatures, and behavioral analysis to flag abnormal activity and vulnerabilities. It analyzes vendor-specific industrial protocols and sends real-time alerts to administrators. The listed architecture includes nNetNDR, netProbe, and nNetSensor: netProbe collects mirrored traffic at Levels 2–3, while nNetSensor collects Level 1 industrial Ethernet traffic. Supported protocols include EtherNet/IP, EtherCAT, S7Comm, and Modbus. NNSP describes deployments in critical infrastructure and industrial settings, including manufacturing and smart factories. Continuous monitoring and early anomaly detection support incident response; tailored reports and consulting are also offered. NNSP was founded in 2003 and is headquartered in Seoul, Republic of Korea. Pricing is on request; contact [email protected] or +82-2-576-4736.
