Who is Indegy?
Indegy is a cybersecurity vendor that provides Operational technology (OT) and industrial control system (ICS) visibility and security for industrial and critical infrastructure environments.
- OT and ICS network visibility and asset inventory for industrial environments (OT security).
- Detection of unauthorized changes and threats across PLCs, Distributed Control System (DCS), and Supervisory Control and Data Acquisition (SCADA) components (industrial threat monitoring).
- Configuration and change management for industrial controllers and related devices (OT configuration management).
- Policy enforcement and governance for access and activities within industrial control networks (OT governance and compliance).
- Integration of OT security data with enterprise Security Operations (SecOps) and Security Information and Event Management (SIEM) tools (security operations integration).

More About Indegy
Indegy focuses on security for OT and industrial control system (ICS) environments, such as manufacturing plants, energy utilities, and other industrial facilities. Its offerings are used by enterprise security teams, plant engineers, and operational staff to gain visibility into industrial assets and to monitor activity that affects programmable logic controllers (PLCs), distributed control systems (DCS), and SCADA components.
The company’s core platform operates by passively monitoring OT network traffic and, in some deployments, by querying industrial controllers using native industrial protocols. Typical supported protocols include Modbus, Ethernet/IP, OPC, and other ICS-specific communication standards. By analyzing both network traffic and controller state, Indegy provides an inventory of connected assets, firmware versions, configurations, and logic running on industrial devices, which is required for security baselining and change tracking in OT environments.
In comparison to traditional IT-focused security tools, which concentrate on endpoints, servers, and standard IP-based applications, Indegy’s technology is aligned to the constraints and requirements of industrial control networks. These networks often contain legacy devices, proprietary protocols, and safety or availability requirements that limit the feasibility of intrusive scanning. Indegy addresses this by emphasizing passive monitoring methods and protocol-aware controller queries designed for OT environments.
From a marketplace and taxonomy perspective, Indegy fits within OT security, ICS security monitoring, and industrial asset visibility categories. Its platform is used to detect configuration changes, unauthorized logic uploads, policy violations, and suspicious network activity directed at industrial controllers. The system can alert on deviations from approved configurations or workflows, supporting incident detection and response for threats targeting physical processes, as well as misconfigurations or human errors that affect plant operations.
Indegy typically integrates with broader enterprise SecOps by forwarding alerts, events, and asset context into SIEM platforms and SecOps center (SOC) workflows. This allows organizations to correlate OT events with IT security data while retaining OT-specific context and risk models. For enterprises with both IT and OT footprints, Indegy’s role is to provide an OT-aware monitoring and governance layer that complements firewalls, network segmentation, and other control measures deployed in industrial networks.
Because many industrial environments must comply with sectoral or national security and reliability frameworks, such as NERC CIP in the power sector or other industrial cybersecurity guidelines, Indegy’s capabilities in asset inventory, change logging, and policy enforcement can support audit readiness and ongoing compliance reporting. This positions the company’s offerings as part of broader industrial risk management and cyber-physical security programs in large organizations.
