CloudSphere can detect and scan MS SQL engine running on Windows endpoints. The network and Windows requirements are the same for any other Windows endpoint.
The additional requirement for scanning SQL Servers is for the MS SQL Server to be configured for clients to connect through Windows Authentication vs through SQL Server Authentication (When a user connects through a Windows user account, SQL Server validates the account name and password using the Windows principal token in the operating system. This means that the user identity is confirmed by Windows)
That is the only option supported by CloudSphere DOI, and this requirement must be met for CAM to be able to pull information from the target MS SQL Server.
