Erbay, compliance manager for the popular online storage provider Dropbox, was at a recent Cloud Security Alliance conference in Germany. He struck up a conversation with an IT manager at a 150,000-employee company. An investigation into that company’s online activity found that employees were using nearly 900 cloud-based applications and programs that relied upon some form of online storage.
