There’s an interesting web service that could be used to pull reporting data from Office 365, assuming you can authenticate using your tenancy’s service admin. Here’s the URL for the service:

Microsoft provide a plug-in to Excel that uses this service and it can be used to pull mail protection statistics from your Office 365 tenancy: https://www.microsoft.com/en-us/download/details.aspx?id=30716
