What is a limitation of cyber security risk insurance?

Cyber security insurance policies, while broad, have specific limitations and exclusions. A common limitation relates to third-party damages. While policies often cover liability for damages to an insured's direct customers (e.g., from a data breach), they may exclude or limit coverage for damages caused to other third parties, such as business partners in the supply chain, as a cascading result of an attack. This area is complex and often subject to sub-limits or specific exclusions, making it a significant limitation compared to more standard coverages like forensics or PR costs.

A. Costs to restore stolen identities and provide credit monitoring for affected customers are a common and standard feature of first-party cyber insurance coverage.
B. Hiring forensic experts to investigate a breach is a fundamental component of cyber insurance, typically covered under incident response expenses.
D. Public relations and crisis management costs are frequently included in policies to help manage reputational damage following a public incident.

1. Cisco, "Cybersecurity and privacy insurance: What you need to know," Cisco Trust Center White Paper, 2021. This paper discusses the scope of cyber insurance, noting that "Third-party liability coverage... protects you from claims by customers, partners, or vendors." However, it also highlights the importance of understanding exclusions, which often involve complex third-party scenarios.

2. National Association of Insurance Commissioners (NAIC), "Cybersecurity," Section on "What Does Cyber Insurance Cover?". The NAIC notes that third-party coverage is for "damages or settlements" but also states policies have "specific perils that are covered and have exclusions," with complex supply-chain (third-party) incidents being a common area of dispute or limitation.

This report discusses systemic risk and supply chain incidents as major challenges for insurers, often leading to coverage limitations or exclusions for damages involving multiple third parties.
