<p><b>New page</b></p><div>🔓 '''Data breach''' is an incident in which sensitive, protected, or confidential information is accessed, disclosed, or exfiltrated by an unauthorized party. In [[Definition:Insurance | insurance]], data breaches are both a major [[Definition:Covered peril | covered peril]] under [[Definition:Cyber insurance | cyber insurance]] policies and an operational risk that [[Definition:Insurance carrier | carriers]] themselves face given the vast stores of [[Definition:Personally identifiable information (PII) | personally identifiable information]] and financial data they hold on [[Definition:Policyholder | policyholders]].<br />
<br />
📂 When a breach occurs, the affected organization typically faces a cascade of costs: forensic investigation to determine the scope and vector of intrusion, notification of impacted individuals as required by [[Definition:Data protection regulation | data protection laws]], [[Definition:Credit monitoring | credit monitoring]] services, legal defense, [[Definition:Regulatory fine | regulatory fines]], and potential [[Definition:Liability | liability]] from class-action litigation. A [[Definition:Cyber insurance | cyber policy's]] [[Definition:First-party coverage | first-party]] insuring agreements generally respond to the direct costs — forensics, notification, [[Definition:Crisis management | crisis management]], and [[Definition:Business interruption insurance | business interruption]] — while [[Definition:Third-party coverage | third-party]] provisions address defense and indemnity for claims brought by affected parties. The speed and competence of the insured's [[Definition:Incident response plan | incident response]] can dramatically influence both the total cost and the reputational fallout.<br />
<br />
📈 Breach frequency and severity have climbed steadily, driven by expanding attack surfaces, [[Definition:Ransomware | ransomware]] monetization, and the growing value of personal data on illicit markets. For [[Definition:Underwriter | underwriters]], this trend demands continuous reassessment of [[Definition:Premium | pricing]] adequacy and [[Definition:Coverage limit | limit]] deployment. [[Definition:Insurance regulator | Regulators]] worldwide — from U.S. state attorneys general to the European Union under [[Definition:General Data Protection Regulation (GDPR) | GDPR]] — have sharpened enforcement, raising the financial stakes for any organization that fails to protect the data entrusted to it. The interplay between evolving breach tactics and tightening legal obligations keeps data breach at the center of the [[Definition:Cyber risk | cyber risk]] conversation.<br />
