Has your attack surface increased as you've moved more workloads to the cloud? While moving to the cloud can be a great idea, it can also be a security headache for IT departments who have not increased their security staff to keep up with the demand. All it takes is one data breach to put your organization at risk and endanger the value that moving to cloud brings.
You are probably using a hybrid cloud. Even for the smallest companies, the litmus test is pretty simple: do you keep some data on a shared drive that's exclusive to your company, and other data on an online cloud storage platform like Dropbox? If so, then congratulations, you're a hybrid cloud user.
