Along with other services that began by focusing on the consumer market and have ridden the consumerisation wave into the heart of many companies, Dropbox has been investing heavily in its business offerings this year, adding features that enable corporate IT departments to oversee and manage file ­ distribution and meet ­ regulatory and other requirements.
