Claroty CTD vs nNetNDR

Claroty CTD is a self-hosted, on-premises platform for protecting cyber-physical systems across civilian and defense networks. It discovers OT and other XIoT assets through passive, active, and AppDB methods, then builds centralized inventories and detailed profiles, including in air-gapped environments. Network maps organize assets into Virtual Zones; CTD can alert on cross-zone communication violations and integrate with firewall and NAC systems for policy-based segmentation. Exposure management compares assets with tracked exposures and current KEV and EPSS reporting to support risk prioritization. Five detection engines profile assets, communications, and processes, establish behavioral baselines, and alert to known and emerging threats in real time. Deployments include on-premises installations and mobile flyaway kits for sensitive settings. CTD integrates with xDome Secure Access, Rockwell Automation AssetCentre, SIEM tools, and approximately 60 technology partners. It supports Modbus, DNP3, CIP, OPC UA, and more than 450 industrial protocols. Pricing is on request.

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.
