Forescout Reviews, Ratings & Features 2026 | Gartner Peer Insights

Gartner defines network access control (NAC) as technologies that enable organizations to implement policies for controlling access to corporate infrastructure by both user-oriented devices and Internet of Things (IoT) devices. Policies may be based on authentication, endpoint configuration (posture) or users' role/identity. NAC can also implement postconnect policies based on integration with other security products. For example, NAC could enforce a policy to contain the endpoint based on an alert from a SIEM.

An organization should evaluate the following capabilities:
•	Device visibility/profiling
•	Access control
•	Security posture check
•	Guest management
•	Bidirectional integration with other security products.
