The Cisco Clean Access Agent is part of the Cisco Network Access Control (or NAC) network security solution that will provide you with a secure and clean network environment by preventing infected and vulnerable machines from joining the University's network. At the same time, it will provide necessary directions and help pages for machines that do not pass the security requirements. UTHSC has implemented the use of the Cisco NAC and Clean Access Agent to make your network experience productive and secure. The Clean Access Agent ensures that any computers connected to the network have sufficient virus protection and system updates installed. Users who want access to the network must pass these checks to get online.


Checks for Windows computers: (referred to as compliance)

  • Valid NetID and Password to gain access to the network
  • Anti Virus Software Installed & AV definitions up to date
  • Windows Updates
  • Domain Membership

Checks for MacOS X computers: (referred to as compliance)

  • Valid NetID and Password to gain access to the network
  • Anti Virus

Cisco Clean Access Agent

If a computer does not meet the necessary requirements, the Clean Access Agent will identify the components that need updating and instruct the user on how to update these items. On Windows computers that are part of the uthsc.tennessee.edu domain, the NetID and password provided upon login to the computer is passed on to the Clean Access Agent so you do not need to enter it again (referred to as single sign on) and validation is performed automatically with no user interaction and takes just a few seconds.

How It Works

The first time you connect your computer to the UTHSC network and launch a web browser, you will be redirected to a page for downloading the Cisco Clean Access Agent. Once the Clean Access Agent is installed, you will not be redirected to this page again.
