To protect their department from cyber risks treasurers can deploy cyber insurance. According to Aon Risk Solutions, while less than 10 percent of companies bought cyber insurance coverage in 2008, that number has more than doubled today to as much as 22 percent.

Not surprisingly, such insurance is growing first in the area of network security and privacy coverage. Banking, insurance, retail and healthcare-related companies lead the adoption of cyber coverage. However, the adoption rate is rising quickly in other industries. So while nearly 70 percent of retailers possess a cyber-insurance policy, coverage in "manufacturing is skyrocketing, as more and more technology is being introduced into manufacturing,". Insurers estimate that about half of Fortune 1000 companies have some cyber risk coverage.
