@cwatson-cat Can you please review this change and approve if you find it appropriate. This information is not currently documented in either Microsoft or Cisco documentation which has caused a large amount of confusion and downtime. Thank you.

@dev-sec7 This article has been refactored and we're now auto-generating the data connectors from the source files in the Azure-Sentinel repo. Cisco Umbrella has its own page that you can find here: https://learn.microsoft.com/azure/sentinel/data-connectors/cisco-umbrella-using-azure-function. #please-close
