Forescout eyeSight

Forescout eyeSight is an industry-leading agentless device visibility and network access control (NAC) platform engineered to discover, classify, and continuously monitor every IP-connected device across enterprise networks. Modern corporate environments are flooded with unmanaged devices—including IoT gadgets, smart cameras, medical equipment, and remote employee laptops—that cannot support traditional security software agents, creating massive visibility blind spots. Forescout eyeSight eliminates these blind spots by deploying passive and active discovery techniques that identify and classify devices in real time the moment they connect to the network. The platform fingerprints each asset down to its vendor, model, operating system, open network ports, and installed software applications without requiring client agents. eyeSight continuously assesses device security posture, checking for missing patches, disabled antivirus software, default credentials, or compliance policy violations. Leveraging rich device intelligence, eyeSight coordinates automated policy enforcement actions—such as network quarantine, VLAN assignment, or software remediation triggers—through native integrations with network switches, firewalls, and EDR systems via Forescout eyeControl. By delivering comprehensive real-time situational awareness across IT, IoT, and OT infrastructure, Forescout eyeSight forms the critical foundation for enterprise cyber risk management.
