Azure Cloud Discovery


This document describes how to set up Microsoft Azure the App for Discovery on OUTSCAN.


The Azure Cloud Discovery scan identifies your Azure instances in cloud environments with provided Azure credentials and querying the Azure API. It enumerates assets via Azure API and get asset identifiers populated describing the tenant, subscription, resource group and instance as well as any assigned IP, hostname or MAC possible to enumerate in the API. Import tags are assigned to the discovered virtual machine instances.


  • Microsoft Azure account (Home - Microsoft Azure)

  • An application in Microsoft Entra ID (formerly Azure Active Directory) with the client secret credential created
