Cyber Risk Modeling

Cyber insurance is one of the fastest-growing lines in commercial P&C — and also one of the lines where carriers are flying with the least actuarial visibility.

Unlike property catastrophe risk, cyber exposures are highly correlated. A single vulnerability exploited at scale can generate losses across thousands of policyholders simultaneously. That systemic risk is genuinely difficult to model, and the historical loss data is thin relative to the exposure growth.

Underwriters in this line are doing sophisticated work with the tools available, but the honest assessment is that models are still catching up to the products being written.

The carriers who will build durable cyber portfolios are the ones investing in threat intelligence integration, rigorous exposure data collection, and scenario analysis that goes well beyond historical frequency-severity patterns.
