Cyber liability insurance covers financial losses that result from data breaches and other cyber events. Many policies include both first-party and third-party coverages. First-party coverages apply to losses sustained by your company directly. An example is a damage to your company's electronic data files caused by a hacker. Third-party coverages apply to claims against your firm by people who have been injured as a result of your actions or failure to act. For instance, a client sues you for negligence after his personal data is stolen from your computer system and released online.
