Network access control (NAC)

A NAC solution protects your network and the information on it from the threats posed by users or devices accessing your network.

There are three main aspects to NAC:

  • Authentication of users and devices to check they are who they say they are
  • Assessment of computers attempting to access the network to make sure they are virus-free and meet your security criteria
  • Enforcement of policies based on the role of the user so each person can access information appropriate to his or her role, while preventing inappropriate access to other information
