nNetNDR
Seoul, Republic of Korea
What it is
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 impacting or disrupting operations. Detection combines ICS-specific whitelisting, signature-based methods, and behavioral analysis to find abnormal activity and security risks. The product analyzes vendor-specific industrial control 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 deployments for critical infrastructure, manufacturing, and smart factories. Continuous monitoring and early anomaly detection support incident response, while tailored reports and consulting address practical OT threat response. NNSP, founded in 2003 and headquartered in Seoul, describes itself as a CPS security company serving critical infrastructure, public sector, finance, defense, and smart manufacturing. Pricing is available on request.
