nNetNDR vs Radiflow iSID

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.

Radiflow iSID provides OT network visibility, threat detection and monitoring for industrial operations and critical infrastructure. It passively analyzes mirrored network traffic to discover OT assets and build an inventory that records their roles and impacts on the environment. The system learns normal network, asset and communication behavior, then detects deviations alongside known threats and vulnerabilities using threat intelligence, SNORT-based and common attack signatures, and CVE mapping. It also monitors configuration changes in PLCs and other network devices without disrupting operations. Deployment can be centralized with iSAP Smart Collectors, placed locally at remote sites, or use a mix of both. The iCEN web interface offers enterprise-wide and site-specific views and centralized management of multiple iSID instances. MSSPs can manage multiple customers with client-based view permissions. A documented Cisco ISE integration shares OT asset context through pxGrid and supports Adaptive Network Control quarantine policies. The iSID 6.0 guide specifies Google Chrome for browser management. Radiflow describes its solutions as serving industrial enterprises and utilities, including critical infrastructure operators. Pricing is available on request.
