Access to sentinel from outside tenant

[Qusai_Ismail]

Hello,

What are the steps to allow user from outside of the tenant(out of domain company) to access the workspace(by using role assignment)

?

Thanks

@Qusai_Ismail There are two different ways to do this.  1) Setup Azure Lighthouse with the external company Manage Microsoft Sentinel workspaces at scale - Azure Lighthouse | Microsoft Docs  2) Setup the user as a guest account using B2B or B2C B2B collaboration overview - Azure AD - Microsoft Entra | Microsoft Docs

Depending on how much access the user requires will help determine which route to go.
