We’ve enabled perfect forward secrecy. By implementing perfect forward secrecy, we’ve made it so our private SSL key can’t be used to decrypt past Internet traffic. On top of this, metadata (including file names and types) is stored separately from the files’ raw data, further obscuring your data from unauthorized access.ģ.

Only blocks that have been modified between revisions are synchronized, which is part of what makes Dropbox sync so fast and reliable. We keep data broken up. Every time you add a file to your Dropbox it’s split into blocks, each encrypted using a strong cipher. Once it reaches us, we lock it down using 256-bit AES encryption at rest.Ģ. We use Secure Sockets Layer (SSL)/Transport Layer Security (TLS) for data transfer to create a secure tunnel protected by 128-bit or higher Advanced Encryption Standard (AES) encryption. We encrypt data in transit and at rest. Regardless of how you’re accessing data you store in your Dropbox - through our desktop app, mobile app, or website, or a third-party app you’ve authorized - it’s always encrypted. I imagine they've heard this FUD line from their Microsoft rep a few dozen times.ĭropbox for Business is secure and we can be specific.įrom a recent Dropbox for Business blog post:ġ. 'Dropbox isn't secure enough for our important business.' We hear it a lot, but when asked for specific examples, there are none.

And the 'bring your own device' (BYOD) flips the traditional security model on its head, offering even more challenges to the legacy security approaches. Before cloud computing, security for the traditionally underserved in the client-server paradigm (SMB, EDU, government, NPO and most enterprises) was usually terrible.

Every organization has dozens of security issues. Security has always been a trade off between safety and convenience as well as reasonable expectations and reasonable budgets. Great security last week could be terrible security this week if an issue was discovered in server software you're running. Security is a constant battle of good guys vs bad guys (actually it's usually good guys vs yourself or your staff) and it's always in flux. Otherwise no one would be using Microsoft Windows. Is security the most important attribute of a technology solution? No, it's not.
