Captive Insurance Expands Role in Cyber-Risk Financing Strategies

Cyber has become one of the most prevalent and costly risks for businesses in recent years.

This risk has the potential to cause financial loss, operational disruption, or reputational damage through the failure of or attack on an organization's information technology systems, encompassing the likelihood of unauthorized access, theft, or data destruction arising from reliance on digital infrastructure.

Given the cost and limited availability of insurance coverage in the traditional market, companies are increasingly turning to captive insurance to self-insure, finance, and manage cyber exposure. By using captive insurance structures, they also gain greater control over claims, can access reinsurance markets directly, and fill coverage gaps left by traditional insurers, such as for reputation damage, data loss, or risks related to artificial intelligence (AI).

"Captive insurance vehicles are rapidly emerging as strategic instruments to finance, structure, and even influence the management of cyber risk," said Jeremy Colombik, managing partner, MSI. "As cyber threats evolve faster than traditional insurance products and market appetites, captives offer organizations a dynamic framework to align risk transfer with their own security posture and operational priorities."

Kim Guerriero, principal and consulting actuary at Milliman, said, "Captive insurers can address the full spectrum of cyber risks. Because every organization faces its own unique challenges, a captive offers the flexibility to tailor coverage accordingly. For example, companies with a history of ransomware claims may struggle to secure ransomware coverage in the commercial market. In these cases, a captive can issue a difference-in-conditions policy to supplement the commercial program and fill that gap."

Alex Clark, vice president and cyber solutions practice leader at Hylant, noted, "Captives provide creative and highly customized coverage structures that reflect the specific operational risks of the insured organization or industry. This allows companies to tailor definitions, triggers, and loss calculations to better match real-world exposures."

Cheryl Critelli, captive insurance legal counsel, Iowa Insurance Division, added, "Captives are opportunities for businesses that may have difficulties in insuring their risks elsewhere—like cyber insurance. Cyber insurance is challenging and volatile, with AI-related coverage often unpredictable or excluded. Cyber is complex, and claims may not be valued right away and could require forensic accounting."

Cyber-Risk Landscape and Key Exposure Areas

Aaron Hillebrandt, principal and consulting actuary at Pinnacle Actuarial Resources, said the main cyber threats include data breaches, malware, ransomware, and cloud and third-party vulnerabilities. He said captive insurance has been used successfully for years to mitigate those direct risks as well as indirect risks, such as supply chain, business interruption, and reputational risk.

"Captive insurance can be a sound strategy for managing cyber risks," Mr. Hillebrandt said. "But there are also challenges associated with cyber insurance that captive insurance companies need to consider and anticipate.

"One of the primary challenges is what I have referred to as a 'devious data dilemma.' Despite the fact that cyber insurance has been around for a while, mature claims databases for cyber liability are difficult to find. Compounding the issue with cyber data is the evolving nature of the cyber threats, including AI-enabled threats, which makes the claims environment volatile. Finally, companies may be hesitant to submit data that could result in the public release of sensitive information, due to competitive or other business concerns."

How Captive Insurance Structures Address Cyber Exposures

Captive insurance programs are no longer limited to classic third-party network liability. Increasingly, they respond to a broad spectrum of cyber-related exposures that mirror the full life cycle of an incident, with common categories written including the following.

• Incident response costs such as forensics, notification, legal counsel, and crisis communications
• Ransomware and extortion payments, including negotiation, decryption, and system restoration
• Network business interruption and extra expense, including contingent business interruption stemming from third-party service providers
• Data restoration and digital asset loss, such as corrupted data, digital infrastructure, or system rebuilds
• Regulatory investigations, fines, and penalties where allowable
• Third-party liability, including privacy breaches, media liability, and failure of network security

Michael Serricchio of Marsh Captive Solutions said, "Cyber has evolved from a niche consideration to one of our top five growth areas across captives globally. We're seeing roughly $166 million in cyber premium running through our captives worldwide—a number that would have been unthinkable 20 years ago.

"The primary use cases are formalized deductible funding, plugging coverage gaps in commercial towers, excess layers and fronted reinsurance arrangements where a certificate of insurance is required. The main challenge is the pace of change: Exclusions shift, limits compress, and the nature of systemic risk—like a widespread cyber-terrorism event—creates exposures that commercial markets simply aren't willing to take on in full, such as cyber-terrorism pursuant to [the Terrorism Risk Insurance Act (TRIA)]."

George Belokas, president, GPW and Associates, said captive insurance is being used to provide stand-alone cyber coverage and to wrap around existing commercial coverage. "Stand-alone cyber coverage may provide reimbursement for cyber liability, business interruption, privacy notification, and other exposures which vary depending on how businesses operate. We also see captives wrapping around existing commercial coverage to provide deductible reimbursement, excess coverage, and to extend sublimits that may exist for business interruption and other components."

Captive Insurance Structures Used for Cyber Risk

Cyber risk is most often written through single-parent or protected cell structures. These captive insurance structures typically operate in the following ways.

Single-parent captives are typically used by multinational corporations with the balance sheet strength to absorb cyber volatility. Cyber may be part of a broader multiline program, often sitting on a primary layer or quota share before purchasing excess reinsurance.

Protected cell captives are increasingly popular for organizations seeking a more accessible entry point into cyber-risk retention or program sponsors offering shared cyber participation to multiple clients.

Andrew MacKay, vice president—captive management at Risk Management Advisors, said, "Single-parent captives give you the greatest flexibility to write cyber coverage and tailor the retention to fit your risk profile. Group captives are generally not going to write cyber coverage, though they may be valuable in helping to set up a group buying program where members can go to [an insurer] in bulk and get reduced rates."

Mr. Serricchio said, "Single-parent captives dominate for larger, more sophisticated organizations that want maximum control over their cyber-deductible funding and premium allocation. We're also seeing interest in cell captive structures for companies that want access to a formal captive mechanism without the setup cost, particularly for writing cyber terrorism under TRIA. TRIA is an interesting angle—if the Treasury certifies a cyber event as a terrorist act, a captive writing cyber-terrorism coverage would receive an 80 percent government backstop on the claim, with payback spread over subsequent years. It's a black-swan hedge, but one that more clients are asking about, especially in industries such as financial institutions, retail, power, and tech."

Lori Gorman, deputy commissioner, Captive Insurance Companies Division, North Carolina Department of Insurance, said, "We see interest in both pure and cell structures to provide coverage for enterprise risks from a wide variety of industries. While a cell may be less costly and easier to establish, some owners prefer the control of a pure captive.

"Pure (single-parent) captives are often formed by larger organizations seeking maximum control over underwriting, claims handling, and long-term capital strategy. Cell structures, however, provide an efficient and cost-effective entry point for small-to-midsized companies that wish to address cyber volatility without the capital commitment of a stand-alone entity."

Mr. Hillebrandt said a larger company with high cyber premiums may opt for a single-parent captive that offers more control. He added that group captives allow companies to align with other organizations with similar risk profiles to obtain lower coverage costs.

"Forming a cell in an existing captive can be a middle ground with some of the control of a single-parent captive, without the added complexities of the risk shifting/sharing mechanisms of group captives," Mr. Hillebrandt said. "And in certain instances, a hybrid structure may be best, with a blend of captive insurance and commercial insurance covering different layers."

Why Captive Insurance Is Effective for Cyber-Risk Financing

Captive insurance structures excel at aligning cyber coverage with an organization's unique risk profile. There are several core attributes that make them particularly effective in this space, including the following.

Design flexibility: Captives can tailor wording, triggers, and sublimits around specific digital assets, critical systems, and emerging threat vectors.

Deductible buy-down: Retained cyber risk can be layered to reduce large retentions or fill exclusions in commercial policies such as for ransomware, contingent business interruption, or nonstandard regulatory exposures.

Access to capacity: When positioned at the reinsurance level, captives can aggregate global cyber risks and access specialty reinsurers otherwise unavailable to local entities.

Data and feedback loop: Retained cyber risk drives improved incident data collection and control measurement, which informs investments in security and risk engineering.

Economic efficiency: Captives can capture underwriting profit and reinvest savings into resilience measures such as incident response readiness, security tooling, and training.

Ms. Gorman said captive insurance provides a controlled environment where organizations can respond more quickly to emerging cyber threats than is often possible in the commercial market. Many companies, she said, are choosing to put cyber-risk coverage into a captive insurance company to obtain more customized coverage, enabling owners to align coverage terms with their internal cyber-security frameworks and enterprise risk management strategies.

Mr. Belokas said captive insurance enables organizations to address the evolving cyber-threat landscape more directly, including rapid shifts in attack vectors, high regulatory expectations, and technology environments that complicate risk quantification and pricing, making it difficult to achieve rate adequacy in the commercial market.

Ms. Guerriero said, "Captives are dynamic, and policies can be structured to address gaps or other challenges in the commercial insurance market. Whether those gaps stem from limited coverage, restrictive sublimits, high premiums, or mandated higher retentions, captive insurance companies provide a flexible solution. By stepping in where the traditional market falls short, the captive industry helps organizations structure coverage that better aligns with their risk management objectives."

Mr. Clark said, "With the right structure, a captive insurance program can provide more consistent coverage, pricing stability, and dedicated capacity over time, even as the broader cyber-insurance market ebbs and flows. Because captives are owned or controlled by the insured organization (or a group of similar organizations), they can be designed to align directly with the company's risk profile, cyber-security investments, and long-term risk management strategy."

Jeff Wilson, captive insurance director, Iowa Insurance Division, added, "Incorporating cyber risk into a captive is not simply about reducing premium spend. It is also about gaining control. A captive allows organizations to design coverage terms, definitions, limits, and triggers that meaningfully reflect their risk profile and provide protection where it matters most."

How Organizations Are Using Captive Insurance for Cyber Risk

Adam Perea, executive vice president, Elite Risk Insurance Solutions, said real-world examples highlight how captive insurance is turning cyber theory into action. He said one financial services group formed a captive insurance company following a severe breach after facing unsustainable commercial pricing. The captive now funds data breach costs, ransomware payments, and regulatory fines, while supporting upgrades to infrastructure and training.

In data-intensive sectors such as health care, Mr. Perea said captive insurance programs are integrating cyber with professional liability and other lines to manage digital and clinical exposures arising from the same event. These structures not only pay claims but finance resilience—funding improvements that reduce both incident frequency and severity over time.

Another key area where captive insurance has been successfully adopted is higher education, according to Mr. Serricchio. Several have structured their captives to allocate deductibles based on departmental compliance with cyber protocols—essentially creating an internal incentive system where safe behavior is rewarded financially.

Challenges in Structuring Cyber Risk in Captive Insurance

Despite the clear advantages that captive insurance brings, Mr. Perea said it also faces several structural and actuarial challenges in underwriting cyber risk. These include the following.

• Modeling low-frequency but high-severity events with limited historical data
• Managing correlation and accumulation across entities, systems, and geographies—particularly from systemic cloud or critical infrastructure events
• Adapting to rapidly shifting policy wording, exclusions, and evolving legal frameworks

Outlook for Captive Insurance in Cyber-Risk Management

Moving forward, captive insurance will increasingly be used to cover cyber risks such as data breaches and AI-related exposures. Its adoption will also be influenced by how the traditional market responds to new and emerging risks.

Mr. Perea said several structural and market trends continue to drive captive insurance adoption for cyber risk, including the evolving threat landscape—encompassing ransomware sophistication, AI-driven attacks, and supply chain compromises—that keep loss potential dynamic and correlated.

"Over the next 12 months and beyond, expect expanding use of captives to support higher retentions, layered cyber programs, and advanced analytics for systemic stress testing," Mr. Perea said.
