Each type of client has its own method for configuring protocols and cipher suites.

Change the security protocols in Horizon Client only if your Connection Server instance does not support the current settings. If you configure a security protocol for Horizon Client that is not enabled on the Connection Server instance to which the client connects, a TLS error occurs and the connection fails.

To change the protocols and ciphers from their default values, use the client-specific mechanism:

  • On Windows clients, you can use either a group policy setting or a Windows Registry setting.
  • On Linux clients, you can use either configuration file properties or command-line options.
  • On Mac clients, you can use a preference setting in Horizon Client.
  • On iOS and Android clients, you can use the advanced SSL options setting in Horizon Client.
