Enhance the current Web Protection reports
Enhance the current scheduled web reports to include at least the pie chart of the relevant data.(The pie chart is available when you manually run the report) The Sophos Web Appliance has a good variety of reports that can be emailed to various people based on different AD groups. Also, to setup departments for the reports is not easy when dealing with 3000 users so being able to use existing AD groups is essential.

Just thought I'd add here that Fastvue Sophos Reporter lets you easily create and schedule reports for all Departments, Security Groups, and Offices from AD.
