NAC was only a network access control and now it has turned to be an advanced example of use to reduce the risks posed by vulnerable and in danger endpoints in today's dynamic networks. It has been emerged as a critical element of an enterprise-wide network security for closing the gap between Security Operations (SOC) and Network Operations (NOC) Centers by eliminating errancy and manual operations via security automation and regulation. 

  As the number of devices on the wired and wireless network continues to grow with initiatives such as Bring Your Own Device (BYOD), the network attack surface for cybercriminals continues to increase at an equal rate. With NAC solutions, all entities in the corporate network are detected in a complete manner and the inclusion of misconfigured systems or the systems that are not in compliance with corporate policies are prevented or taken out of the corporate network.
