You cannot improve your data protection using insurance products without increasing costs.
To get insurance protection you need to have good demonstrable, documented and maintained security practices in place, such as ISO 27001 certification, as well as additional requirements (ISO 9001, ITIL, dedicated skilled security staff etc).
If you do not have those security measures in place, or the measures you have do not meet the requirements set out by the insurance company, your costs to gain insurance will increase or you will not be offered insurance at all.
Insurance is based on the assessment of risk and a company’s risk appetite, and those of an insurance company need to at least match in order for insurance cover to be issued.

If you have all the required security practices in place, then insurance should cover for unpredictable events such as security breach occurring within say three hours of a critical patch being released ie insurance is no substitute for good security practices.
