Results suggest that there is a potential shortfall by others in the Fortune 1000 in assessing cyber risk. Other key findings include:

• 44% of tech/telecom companies use technical safeguards
• 20% report inadequate resources to limit cyber losses
• 11% have purchased insurance for cyber exposure

"The issue of cyber vulnerability through vendors has been thrust into the spotlight following news reports that a recent breach at a major retailer was through a vendor's access to the retailer's systems. Awareness of outsourced vendor exposure needs to be high on the radar of all tech and telecom firms," said Sara Benolken, Willis' global industry leader for technology, media and telecommunications.
