If my company data storage needs were so huge and it was clear that using this service provided large economical savings and provided as good if not better security protection than was already in place, then yes I would use the service. However if the company data was highly sensitive (like the federal government top secret intel) then I would not be apt to use this service. I believe there will never be a %100 secure information system as long as people are alive. Evil exist and people possess it and are driven by it for self-serving needs and will always figure out ways to crack any system to do damage.
