NAC Agents – Not The Solution To Look For

I have been speaking about this for some time now – a NAC solution that relies on agents is a solution, which would be bound to fail in deployment. The problem is more emphasized on large-scale deployments.

I can count several reasons like the problem of identifying all the elements that the agent needs to be installed on (organizations do not know what they have on the network as is. …And most of the NAC vendors do not know that to…), the NAC agent is one among many other agents that may already be installed on the element, a performance impact that may result from the agent, management overhead, and the fact that the agent is a target for a security breach.

Seems like I am not alone talking against the NAC agent approach. Tim Green of Network World published in his newsletter an article about issues with NAC agents.
