Very yes (we don't allow Dropbox† on our machines, but we know of companies that rely on it).

Grandalf's point is extremely well taken. It's actually true. Not only that, but regulated companies (in health care and finance) that have a reasonable belief that any of their systems might have had Dropbox on them technically need to audit now.

I point this out not to bag on Dropbox, but as an illustration of how sane some unreasonable-sounding IT policies (like, "you don't get to install random software on your desktop") turn out to be.

† (Or Tarsnap or SpiderOak, for what it's worth.)

Why not Tarsnap?

I like Tarsnap. If I had to recommend a 3rd party storage vendor, it would be Tarsnap.

I know, but that doesn't answer my question. Why is it banned at your shop?

If I had to guess, I'd say it's because they cannot prove to a third party that it meets all HIPAA (or insert your own group here) requirements.
