Are network access control products finally living up to their billing?

Network access control (NAC) products sound like a good idea. And they seem to work well to protect against inadvertent pollution by authorized users. But some experts think we should be skeptical that NAC products can fend off hostile attacks. Do you think NAC products are being oversold as the last word on network security? How do you use them at your client sites?

Chris has pointed out well but on the other side of the story”
1. How much of these tools effect on the network choking and speed?
2. Is the policy of the organization matching with the NAC products being used?
3. Do we really require controlling all what it is doing?
4. Is it not throwing a challenge to the end-user or provoking him to find out other ways of doing what he intends to do?
5. Have the rule-sets defined clearly and most optimally to balance the network availability, and the checks/controls to be built on the network for inadvertent pollution?
6. Is a clear cut definition of ‘inadvertent pollution’ available across the table to the management and all users?
7. Is it the only way of controlling it?
