Dropbox for Business is still a public cloud service. The reality is we live in information economy where information and intellectual property is a first order citizens for any business. So storing your organization data to a public cloud (whether it is dropbox or some other service) is equivalent to giving keys to your organization's treasure trove. Also Dropbox being a high profile target, if the service hacked for some reason, it puts your organization data at risk in inadvertently.

We have built Tonido FileCloud (http://www.getfilecloud.com) to specifically address this use case where organizations can self host their own Enterprise File Share and Sync platform.
