The cost of business interruption is the leading cyber-risk concern for businesses, according to Aon Global Risk Consulting.

The group’s global benchmarking report, the Captive Cyber Survey, gauges organisations’ attitudes to cyber threats, risk assessment, insurance-buying trends and loss adjustment concerns.

Peter Mullen, CEO of Aon’s Captive and Insurance Management practice, says the findings show a disparity between companies recognising cyber as one of the fastest-growing risks and understanding what their exposures and coverage needs are.

The survey shows 94% of companies would share risk with others in their industry.

Aon experts expect alternative risk transfer options will become increasingly popular because they give companies some control over underwriting, coverage scope and claims adjustment, while providing an opportunity to share best practices, experience and data.

The survey also shows 95% of respondents believe clear policy wording is the most important issue in the cyber-risk market, and 75% of large companies are concerned about the loss adjustment process.
