NAC deployment must be complete

NAC must scale. The deployment must include all sites, and not just a certain portion of the environment. If dependent on an appliance and/or on the switching fabric, it is bound to fail (time-to-value, effort and money).

Any NAC deployment must cover the entire environment, so other venues accessing the network would not be possible.

One good example is with guest access. Enforcing guest access on specific locations, such as meeting rooms, etc. would fail once the guest will connect to those unprotected locations.
