Cyber insurance is a mechanism for transferring financial risk associated with cyber incidents from organizations to insurers. As a research concept, it investigates the design, pricing, market structures, and effectiveness of specialized insurance products intended to mitigate the diverse financial, operational, and reputational losses arising from cyber threats such as data breaches, ransomware attacks, and business interruption. Key areas of inquiry include risk modeling challenges, policy coverage evolution, regulatory implications, and the potential for cyber insurance to incentivize improved cybersecurity practices. Its significance lies in addressing the growing financial exposure posed by cyber risks and its role in organizational risk management strategies and the broader digital economy.
