Which license is considered the "Base" Forescout license?

The "Base" Forescout license is indeed the eyeSight license. This license is foundational because it provides the essential functionality needed for network visibility and security. eyeSight enables organizations to discover, classify, and monitor devices connected to the network in real-time, thereby forming the backbone of Forescout's solutions. With this license, users gain visibility into the types of devices accessing their network and can begin to implement security policies based on this information.

The other options, while important in their own right, serve as additional capabilities or advanced functionality that build upon the foundational visibility provided by eyeSight. For instance, the vFP (virtual Forescout Platform) license allows for deployment in virtualized environments, Endpoint Management relates to managing endpoint security, and Device Intelligence enhances the capabilities of the system by providing deeper insights into device behavior and risk assessment. However, these functionalities would not be available without the basic foundation that the eyeSight license provides.
