nNetNDR

What nNetNDR is

nNetNDR is a self-hosted security product for monitoring industrial control system and operational technology networks. It analyzes mirrored network traffic passively to identify OT assets, communication flows, protocols, threats, and vulnerabilities; the maker says this approach does not affect or disrupt operations. Its 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 in critical infrastructure and industrial control environments, including manufacturing and smart factories. Continuous monitoring and early anomaly detection support incident response, and the maker says it provides tailored reports and consulting for practical OT threat response. NNSP describes its focus as CPS security, including cross-domain and ICS/OT solutions for critical infrastructure, public sector, finance, defense, and smart manufacturing. The product is paid, with inquiries directed to NNSP.
