nNetNDR is a self-hosted security product for industrial control system and operational technology networks. It passively examines mirrored traffic to identify OT assets, communication flows, protocols, threats, and vulnerabilities without disrupting operations. Detection combines ICS-specific whitelisting, signature-based methods, and behavioral analysis to flag abnormal activity and security risks. The product analyzes vendor-specific industrial protocols and sends real-time alerts and notifications to administrators. Its 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 use in critical infrastructure, manufacturing, smart factories, and other industrial control environments. Continuous monitoring and early anomaly detection support incident response, while tailored reports and consulting address practical OT threat response. NNSP is based in Seoul and was founded in 2003. Pricing is available on request through NNSP.
