How does ForeScout ensure agentless operation?

ForeScout ensures agentless operation by utilizing passive monitoring techniques. This approach allows the system to assess and monitor devices on the network without the need for installing software agents on those devices. Passive monitoring involves listening to network traffic and collecting data about devices as they communicate over the network. This way, ForeScout can identify, classify, and enforce security policies on devices in real-time, ensuring comprehensive visibility and control without requiring changes or installations on the endpoints themselves.

Utilizing passive monitoring is particularly beneficial in environments where deploying agents might be challenging, such as in BYOD (bring your own device) scenarios or in networks with a variety of device types. It simplifies the deployment and maintenance of security measures since it reduces the overhead associated with managing agent software.
