External UZH Network Access (VPN)

What is VPN? UZH members who are outside the UZH buildings or in their home office have secure access to the UZH network via the "UZH Virtual Private Network" (VPN). This allows you to access systems that are only accessible within the UZH network. VPN also encrypts public connections. More...

Important: Authentication is not equal to encryption. On public networks you authenticate with a password, however, data traffic, that is not additionally encrypted, can be read by the operators of the networks or other persons in the same network.

You will find the relevant instructions under the following drop-down menus.


VPN on private MAC/Windows devices


  • Please note that you must have admin rights on the device in order to fully install and configure the VPN client.

  • If you have difficulties accessing e-resources (databases, journals), you can alternatively use the browser-based solution EZproxy (instructions (german) (PDF, 1 MB)).

  • If you are using a mobile device, please consult the instructions under the section VPN on mobile devices (iOS/iPadOS & Android).

  • Information on recurring questions and problems can be found on our FAQ page.

Installation via the UZH Sharepoint page:

  • Go to and log in with your personal UZH login data.

  • Open the "Version 22.6.1" folder and then that of your operating system (for Windows "Windows 64-bit" / for Mac "Mac OS").

  • Download the two files.

  • After downloading, first execute the "PulseSecureAppLauncher..." file and then the "PulseSecure..." file.

  • Allow/confirm each time during installation.

→ Once the installation is complete, the Ivanti Secure Access Client can be opened on the computer.

  • Click the + in the VPN client menu and enter the following information:

Type: 'Policy Secure (UAC) or Connect Secure (VPN)'

→ Click "Connect" and log in with your personal UZH login data, then the connection should be established.

Notes regarding macOS:

  • If you are asked to select a certificate during the installation/connection setup, you must select the "Kerberos" certificate.

  • During the installation, you will automatically be asked to confirm that Ivanti should be allowed to make changes to the computer/establish a connection. Simply follow the instructions. → Afterwards, this can be enabled via Apple menu > Privacy and security (Ivanti should already be available for selection there, click "Allow").

  • If you receive an error message of the type "Please enter a valid ICS URL" -> Please note the FAQ entry #02.

  • If it is not possible to establish a connection after installing the two downloaded files, it may be necessary to restart the device.


   macOS - via the icon in the menu bar (right-click > UZH VPN > Disconnect)

   Windows - Call up the client via the icon in the taskbar and click on "Disconnect".

Re-establish the connection:

   Open the Ivanti Secure Client and connect to UZH VPN.

Special Case: Linux

Unfortunately, Central IT cannot offer support for Linux computers. For this reason, please find below a model guide for Ubuntu.

  1. Install the 'PulseUI Client' from this SharePoint site: (VPN Clients (Ivanti (Pulse Secure))).
  2. Install the necessary libraries:
      - Ubuntu and Debian:   sudo apt-get install libnss3-tools
  3. Execute the installation with the following commands:
    Once the downloaded files are saved to the directory /$HOME/Downloads, ...
    - For Ubuntu: sudo dpkg -i /$HOME/downloads/
    - For Debian-based Linux versions (similar to Ubuntu):   sudo dpkg -i
    - For RPM-based Linux versions (such as CentOS):   sudo rpm -ivh
  4. A shortcut to the VPN client is created in the start menu under 'Accessories -> PulseUI' . This points to the file /opt/pulsesecure/bin/pulseUI .
  5. pulseUI requires Chromium Embedded Browser (CEF) and will try to install it if necessary. If the installation fails, you can do it manually with ...
       'sudo /opt/pulsesecure/bin/ install' .
