Which device discovery method does Forescout NOT utilize?

Forescout utilizes various methods for device discovery to ensure a comprehensive view of all devices on a network. However, syncing directly with Active Directory is not one of those methods for device discovery utilized by Forescout.

When discussing the discovery methods Forescout employs, querying switches allows the system to gather information about devices connecting to the network via Layer 2 and Layer 3. Similarly, third-party security device integration means that Forescout can collaborate and extract information from other security systems already in place, enhancing its inventory and policy enforcement capabilities. Meanwhile, utilizing Netflow sources permits Forescout to analyze the network traffic flows, enabling it to identify devices based on their communication patterns.

In contrast, Active Directory syncing primarily focuses on managing user accounts and permissions rather than discovering devices. Although it's beneficial for user endpoint management and monitoring, it does not provide the specific visibility into the network's connected devices that Forescout requires for its operational capabilities. This distinction clarifies why Active Directory syncing is not employed as a discovery method within Forescout's framework.
