It is a product like any other insurance policy, that is brought by businesses to protect themselves from risks involved with Internet and information technology. Such risks are not covered under commercial liability policies which is why, the need of such an insurance comes into picture. It provides cover for losses due to hacking, denial of service attacks, destruction or loss of data, etc. Protective measures like anti-spam systems, virus protection, etc., fail at some point in time as they are not 100% foolproof. After a security breach, businesses need to restore their information systems, clean up infected files, etc., due to which they fail to continue their business for quite some time. All this calls for a lot of expenditure in times when they are not making money. At such instances, this coverage supports them to take care of their financial needs.
