I know Azure Sphere is new, and to my understanding Microsoft is targeting the embedded IOT market, but how is Azure Sphere more secure than other embedded RTOS systems like VxWorks or Integrity? Don't many of the embedded security measures mentioned at https://www.microsoft.com/en-us/azure-sphere/details/ already exist in most embedded devices? Is it their combination of using hardware and software security measures that will give Azure more security than normal embedded operating systems?
What separates Azure Sphere from other security focused embedded operating systems?
