Extreme Networks 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.

We moved from NetSight which was an app to XMC which is web based. It is a snappy interface that offers great insight as to what our switching environment looks like.

NETWORK ADMINISTRATOR

Overall good Network Access Control system. Very granular control of roles you can assign. Downside is they are getting rid of their Posture Assessment piece.

SYSTEM ADMINISTRATOR

The solution is really easy to setup. If you already have ExtremeCloud IQ Site Engine, it's just one OVA image to deploy, and that's it ! Or two if you want redundancy, and you want it !
The only negative thing is the administration GUI which is a bit confusing, a lot of menus and no clear path to create the rules and all the things needed.
