Overview

Complete security starts with an accurate inventory of all assets, where they are located and their compliance status. With the rapid digitalization of critical infrastructure and manufacturing environments – often geographically dispersed across large sites – accurately identifying and managing all OT, IoT, and IT assets is increasingly challenging. Moreover, industrial assets use proprietary protocols and are more fragile than most, making them and the processes they support difficult to identify.

Discovery approaches that work for IT and IoT might not work for sensitive OT devices given safety rules, vendor interoperability issues, industrial process requirements, and other considerations. When OT devices control critical infrastructure, there can be no downtime or service disruptions. Therefore, non-intrusive passive monitoring or agentless techniques are required.

Forescout offers continuous discovery of all cyber assets across all networks, providing full visibility into OT/ICS networks that detect cyber threats before they lead to operational or security incidents. In-depth asset management and monitoring of OT networks and device types employs more than 30 passive and active discovery techniques, identifying assets, their location and cyber posture, and to detect anomalies. This includes deep packet inspection (DPI) of 300+ IT, OT, and IoT protocols as well as carefully selected active queries for OT/ICS to query selected endpoints, including industrial controllers and network infrastructure for complete device visibility, well beyond SPAN.

Unlike other vendors that focus on visibility, the Forescout platform goes much further and delivers control capabilities to automate orchestration, remediation, containment, segmentation, and enforcement to ensure security and compliance across managed, unmanaged, and unagentable devices. Whether organizations are transitioning to the cloud, maintaining air-gapped systems, or managing hybrid infrastructures, Forescout for OT Security seamlessly adapts to the specific needs of customers, offering scalable deployment across OT, IoT, IoMT, and IT systems without limitations.
