  • Then click Users and Groups, and then select the users you want to assign the Vanta app to. 
    If you want the application to be applied to all users, then it's recommended to select the 'All Users' group as seen in the screenshot below, as this will also include future uses added to the group.

Common Issues

  • When attempting to login I'm redirected to a page saying "Account Not Found"

  • The most common cause for this error is the "Vanta O365" has not been assigned to that user's profile in Azure, or they are not assigned to the group that automatically provisions the app.

    Check that the user:
    • is assigned to the group where the Vanta O365 app was applied
    • has the app assigned to their Azure AD user profile
    • has Office365 as the primary source of their employment information (see here on how to check this)
    • Is using the email address registered to their Vanta profile
