Download VPN Client

The Cisco VPN Client is only for use of members of the TUHH. Propagation of the program, for example on your homepage, is not allowed. Because of this, the VPN Client is only downloadable from the network of the TUHH (additional information from Cisco to export regulation). A download from external is only possible over our WebVPN service.

The VPN Software is available for the following operating systems:

Windows 10 / 11

Apple (iOS and MacOS)

We recommend using the above profiles, which use the native VPN client built into the operating system.
However, if videoconferencing systems are to be used within a VPN session (which we do not recommend), it may make sense to use the Cisco AnyConnect Client for MacOS instead of the built-in VPN Client.
Please also read the Apple MacOS manual.

GNU / Linux / Ubuntu

The required sotware can be found in the repository.
The manuals and help sites show you the necessary steps.
