Indications from a study of public documents conducted by Willis Group Holdings suggest that some companies may be underestimating their cyber risk exposure.

The Willis report, 10K Disclosures – How Technology and Telecom Companies Describe Their Cyber Liability Exposures, revealed that technology and telecommunications companies estimate their cyber exposures at higher levels than others in the Fortune 1000.

"We looked at how tech companies estimate their own cyber exposures, and they're seeing higher frequency and severity of exposure than others in the Fortune 1000," said Ann Longmore, the head of D&O, Fiduciary, and EPL Products for Willis FINEX in North America and co-author of the study. "Significantly, they are twice as concerned about outsourced vendor risk."
