You can deploy ESM for Fusion within the same cluster as ArcSight Interset. As an administrator, you do not have to perform any additional configurations in ESM for Fusion to integrate data from Interset.
NOTE:To use the Layered Analytics capability, you must deploy both Interset and ESM for Fusion in the same cluster.
Interset users automatically have single sign-on access as long as the first administrative account for Fusion matches the credentials for the Interset administrator, which is the administrative account that was specified during the deployment of Interset. Users with Dashboard permissions automatically receive the Default Tenant status in Interset. These users can view content in widgets that display data from Interset. The User Guide for Fusion, available as context-sensitive help within ESM for Fusion and posted with the documentation for ArcSight Platform, indicates whether a widget needs data from a specific data source.
