8MATE for SharePoint displays all permissions and group members on a SharePoint farm.
You can view all permissions across multiple levels at-a-glance, whether the query relates to a site collection with wikis or across multiple SharePoint farms. You are also able to find out which permissions were modified during a specific time-frame through the before-after-comparison reports. These scan reports can be exported in Excel format for added comfort. The process of granting permissions is made significantly easier with this technology.
