nNetNDR
nNetNDR is a self-hosted product for passively monitoring industrial control system and operational technology network traffic. It 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 vulnerabilities. The product analyzes vendor-specific industrial control protocols and sends real-time alerts and notifications to administrators. Its architecture lists 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 and industrial control environments, including manufacturing and smart factories. Continuous monitoring and early anomaly detection support incident response. The maker also describes tailored reports and consulting for practical OT threat response. NNSP is headquartered in Seoul and was founded in 2003. Pricing is available on request. The product page lists GS and KC certifications, PPS Preferred Product, a Korean patent, and a New Software Product Award.
