Martyn Croft's boss is David Clayden, the Chairman of the Charities Consortium IT Directors' Group (CCITDG), looked into alternative products that would still meet budgetary and performance criteria while enabling the functionality and reporting that he required to centrally manage USB device usage at The Salvation Army. He chose Lumension Security's Sanctuary, which is endpoint security software that enables central management of all removable storage media and applications that run on corporate networks. Sanctuary works on a "whitelist" model, whereby only the devices and applications that are specifically authorized by the IT department are able to connect to or run on the corporate network. Nothing else is permitted to connect or run on the network. This enforces acceptable use policies throughout the organization by simply blocking the use of any device or application that has not been authorized by the IT department.
