Summary of Xobni Effectiveness

I used Xobni about a year ago to help a team of project managers and subcontractor untangle their email systems. I know the company and products have improved since then, but don't have time to research on my own. I need a two page single spaced memorandum to persuade a CEO/CFO/IT department head that Xobni will be safe for their network, and who others use it. Xobni will allow users to track who they are emailing most frequently, to do a process analysis. Xobni will be cost effective as a trial.
