For Good Measure: Is the Cloud Less Secure than On-Prem?

So you got to let me know,
Should I stay or should I go?
—The Clash

According to Deloitte's Chief Cloud Strategy Officer, "[2019] is the year when workloads on cloud-based systems surpass 25 percent, and when most enterprises are likely to hit the tipping point in terms of dealing with the resulting complexity". Given the nature of For Good Measure (this column), it may surprise you that it wasn’t the 25 percent statistic that caught our attention in Deloitte’s quote; it was reference to a "tipping point" where "dealing with the resulting complexity" in the cloud begins to negatively affect security. So we ask, do we see evidence that this is occurring? Are the rate of security exposures in the cloud higher than on-prem?
