OTDefend
OTDefend provides passive monitoring, threat detection, vulnerability management, and response for industrial environments. Its network intrusion detection inspects more than 16 industrial protocols from a mirror or TAP port, and the maker says it does not inject traffic. Supported protocols include Modbus, S7comm, DNP3, EtherNet/IP, IEC-104, IEC 61850, PROFINET, EtherCAT, POWERLINK, CC-Link IE, OPC UA, BACnet, FINS, MELSEC, and HART-IP. A dependency-free Windows agent runs from Windows XP through Windows 11 and collects host inventory and intrusion-detection events. Detection combines network IDS signatures, Sigma analytics, and YARA signatures; the homepage states 688 rules. A built-in threat-intelligence store accepts TAXII 2.1 and STIX 2.1 feeds and checks indicators against live traffic. Deployment options include an offline Docker bundle, a .deb sensor, and a bootable appliance ISO. OTDefend lists SIEM and other security integrations, plus IEC 62443, NERC CIP, and NIS2 reporting with exportable PDFs. Its design includes per-tenant isolation, role-based access, an active/standby core, and one-way sensors for data-diode segments. Pricing is on request.
