Remote Access Services — VPN and Citrix

Remote access to network files and administrative applications on the Columbia network via VPN and Citrix.

Also known as VPNCitrixRDP or XenApp.

On this page:

CUIT provides two methods for faculty, researchers, and staff to connect to the Columbia network from a remote location: VPN and Citrix. Students, including international students, are not eligible for VPN or Citrix through CUIT at this time.

Please note: The Citrix software is also used by other groups at Columbia such as SIPA. The information on this page only applies to CUIT Citrix.

Most of Columbia’s systems can be accessed directly in your web browser, but certain restricted administrative applications require the CUIT VPN (virtual private network). VPN is also the solution for most users to connect remotely to your shared files on the University network. If you are one of CUIT’s customers that pays for access to the Columbia Central Server, you can use CUIT Citrix to access certain applications and resources on the server.

Before utilizing either remote access service, please refer to the Columbia University Remote Access Policy in the Administrative Policy Library for specific requirements and guidelines.

Please remember that most of Columbia’s systems can be accessed directly in your web browser without using VPN or Citrix, freeing up licenses for other users. If you have been authorized to access these systems, the best way to log in remotely is by navigating to the portal and simply using your UNI and password. The Columbia U Secure network eliminates the need to use VPN while on campus in order to access Columbia administrative resources.
