“A siloed security approach can create network blind spots that have costly, long-term impacts on business continuity and brand reputation,” Kissel said. “Without full network visibility, these attack surfaces will only increase, given the fast-growing number of BYOD [bring your own device] and IoT [Internet of Things] devices being connected to corporate networks.”

Managed devices experienced the most security incidents, despite increased investment in managed security technologies. Managed end-user computers yielded the highest network-based security incidents, with nearly one-third of companies in the U.S., 19 percent in the U.K. and 50 percent in Germany reporting five or more.
