How Secure Are Dropbox and Other File-Sharing Services?

Last week, both Dropbox and Box were in the news over another security breach. This one inadvertently exposed data through publicly shared links.

The two file-sharing services, as well as many others, allow users to create shareable Web links to share data. The links are made up of a string of letters and numbers and, because of their the complexity, are supposed to be impossible to guess. However, numerous public links for Dropbox were, in fact, discovered last week through referral data in Google Analytics, along with search results in Google Adwords. In response, Dropbox disabled all access to public links and created a patch to keep shared links from being made public again.

This is the third security breach for Dropbox in as many years. With incidents like this on the rise, Firmex Data Rooms takes a closer look at the leading document-sharing providers on the market, to assess just how secure they really are and what happens to user data once it's uploaded to the cloud.

    Only a few of the above listed support client side encryption.

    Most of them use server side encryption instead of client side encryption. This means the keys are on their servers. When you aren’t managing your own keys, you don’t have control over your data.

    Consider encrypting your files on the client side ( before uploading them.
