Forescout Technologies, Inc. is a cybersecurity company focused on continuously identifying, protecting, and helping ensure the compliance of managed and unmanaged cyber assets across IT, OT, IoT, and IoMT environments. Its portfolio is anchored by the Forescout 4D Platform, which brings together asset intelligence, policy-based control, risk and exposure management, segmentation, and threat detection and response for complex enterprise and industrial environments.
Forescout Technologies, Inc. centers its approach on agentless visibility, device classification, and automated enforcement across heterogeneous networks, including environments where traditional agents are impractical or disruptive. The company supports campus, data center, cloud, hybrid, remote, and air-gapped deployments, and it extends its platform through integrations and marketplace apps that connect security, IT, and operational workflows.
Offerings, Capabilities, and Integrations
Forescout Technologies, Inc. delivers capabilities spanning cyber asset management, continuous threat exposure management, network access control, segmentation, OT and cyber-physical systems security, and threat detection and response. Its technology is built to discover and assess managed, unmanaged, and unagentable assets using agentless monitoring, passive profiling, deep packet inspection, and persistent asset context.
The portfolio is designed to work with existing infrastructure rather than forcing wholesale replacement. Forescout Technologies, Inc. supports bidirectional data sharing and workflow orchestration across ITSM, CMDB, SIEM, case management, endpoint, cloud, and network security tools through APIs, marketplace integrations, and an app ecosystem. Deployment options span on-premises, cloud, hybrid, and isolated environments, which makes the offerings suited to regulated and operationally sensitive organizations.
