In a typical insurance policy, a data breach refers to an incident where personal or sensitive information held by the insured party is accessed, disclosed, or lost without authorisation, potentially resulting in harm to individuals or liability for the business. This definition often aligns with legal standards and is used to trigger coverage under cyber liability or data breach insurance, which may include costs for forensic investigation, customer notification, legal defence, regulatory fines, and public relations efforts.
