Network admission control system

Cisco NAC Appliance, formerly Cisco Clean Access (CCA), was a network admission control (NAC) system developed by Cisco Systems designed to produce a secure and clean computer network environment.
Originally developed by Perfigo and marketed under the name of Perfigo SmartEnforcer, this network admission control device analyzes systems attempting to access the network and prevents vulnerable computers from joining the network.
The system usually installs an application known as the Clean Access Agent on computers that will be connected to the network.
This application, in conjunction with both a Clean Access server and a Clean Access Manager, has become common in many universities and corporate environments today.
It is capable of managing wired or wireless networks in an in-band or out-of-band configuration mode, and Virtual Private networks (VPN) in an in-band only configuration mode.
Navarro Networks, Inc., was a developer of Ethernet-based ASIC components based in Plano, Texas, in the United States.
