Automatic Cisco AnyConnect Client Update

On Monday, November 29, from 10:30 to 11:30 p.m. ITS will update the Cisco AnyConnect client to address security vulnerabilities. After the maintenance period, when you launch the Cisco AnyConnect client to log into the Virtual Private Network (VPN), you may receive the automatic update. The following computers will receive the automatic update of the Cisco AnyConnect client:

  • Unmanaged Mason-owned computer (Windows, Mac, or Linux)
  • Mason-managed computer (Windows only)
  • your own personal computer (Windows, Mac, or Linux)

You may be prompted to reboot your computer after the update; however, this is not required for the update to work. Please allow extra time to install the update.

Note: Mac Mason-managed computers have already received this update and do not need to take further action.

If you are in an existing VPN session prior to or during the maintenance period, you will not receive the automatic Cisco AnyConnect client update until your current VPN session ends and you try to reconnect to the VPN. Additionally, the Cisco AnyConnect automatic update will not terminate an existing VPN session.

The Cisco AnyConnect client download is also available on the Virtual Private Network (VPN) service page.

If you are having problems connecting to the VPN after the update, please contact the ITS Support Center at 703-993-8870 or
