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.
