A European agency has called for insurers to offer better cover to protect businesses against losses caused by online crime and technical problems.
Although some companies already offer specialist "cyber insurance" policies, the European Network and Information Security Agency says the insurance industry needs to work harder to build up the market.
According to the agency, one of the biggest problems is that insurers don't always have an accurate idea of exactly how likely cybercrime is, or the potential costs. This makes it much harder to set premiums that are competitively priced but still profitable.
To counter this, the agency says insurers need to work together and share more data about premiums, claim payouts and the frequency of claims. It also says insurers should collaborate to produce advice for businesses to help them reduce the chances of suffer cybercrime.
Another suggestion is for insurers to combine research on how much cybercrime costs, meaning potential customers can be given a clear idea of the true value of their data and thus the damage they could suffer if not insured.
One big limitation to the proposals is that governments across Europe aren't necessarily willing to provide a safety net for insurers in the event of a catastrophic event, for example in the way the UK sometimes picks up the tab for damages caused by rioting.
