Please note the following, especially if you use any special policies or other components between the devices and the IGEL Universal Management Suite (UMS) or the IGEL Cloud Gateway (ICG):

  • IGEL OS 12 devices use TLS 1.3. TLS 1.2 only is not possible.
  • IGEL OS 11 devices use TLS 1.2. 


The UMS Server as well as the ICG are by default configured to support Apache Tomcat with TLS 1.2 and TLS 1.3.
