+### For new customers only: Automatic onboarding and redirection to the Microsoft Defender portal
+
+For this update, new Microsoft Sentinel customers are customers who are [onboarding the first workspace in their tenant to Microsoft Sentinel](quickstart-onboard.md) on or after **July 1, 2025**.
+
+Starting **July 1, 2025**, such new customers who have the permissions of a subscription [Owner](/azure/role-based-access-control/built-in-roles#owner) or a [User access administrator](/azure/role-based-access-control/built-in-roles#user-access-administrator), and are also not Azure Lighthouse-delegated users, have their workspaces automatically onboarded to the Defender portal together with onboarding to Microsoft Sentinel. Users of such workspaces, who also aren't Azure Lighthouse-delegated users, see links in Microsoft Sentinel in the Azure portal that redirect them to the Defender portal. Such users use Microsoft Sentinel in the Defender portal only.
+

+
+New customers who don't have relevant permissions aren't automatically onboarded to the Defender portal, but they do still see redirection links in the Azure portal, together with prompts to have a user with relevant permissions manually onboard the workspace to the Defender portal.
+
+This change streamlines the onboarding process and ensures that new customers can immediately take advantage of unified security operations capabilities without the extra step of manually onboarding their workspaces.
