"We promptly moved our external secure storage to a different vendor's system."
I hope they bothered to check the new vendor out, assured themselves that they could provide an actually secure system (rather than what they already had which, presumably, was sold as "external secure storage"), and set the new system up correctly so that it actually is secure this time. Otherwise they've just moved the same data to a different target and they'll be recylcing this press release in a few months and promptly moving their external insecure storage again.
