How many enterprises have found their data under attack in the past year? All of them, according to a new survey of C-level executives in the U.K.

If everyone is under attack, how many have had their defenses pierced?

The study, it should be noted, was sponsored by IBM, so the usual caveats about vendor-sponsored research apply.
