Cyber insurance has become more than a finance department’s annual purchase. Underwriters increasingly examine how security controls work in practice, and the CISO is often responsible for translating that posture into evidence, explaining the remaining financial exposure, and helping the organization meet policy conditions during an incident. The goal is not to make the company look insurable; it is to build resilience and use insurance to transfer a defined portion of the risk that remains.
Why insurance is now a CISO concern
Insurers have a financial reason to ask detailed questions about security: losses can turn on whether basic protections were deployed across the systems that matter. Ransomware, data theft, business-email compromise, system failure, and attacks on suppliers produce different costs. A control that covers employee email but not privileged accounts, cloud administration, remote access, or backups may leave a consequential gap.
Underwriting may combine an application with external attack-surface scans, threat intelligence, claims data, business characteristics, and requested limits. Corvus, for example, says its underwriting considers scan results, revenue, business type, cybersecurity controls, and the coverage requested. Its application asks about matters such as MFA scope, privileged access, EDR/MDR, and backup protections. Corvus’s underwriting overview and application illustrate how far these questions can reach into security operations.
Market movement needs careful interpretation. The NAIC reports global cyber-insurance premiums of nearly $15 billion in 2024, up about 7% year over year. In the United States, direct written premium fell from about $9.84 billion in 2023 to $9.14 billion in 2024; policies in force were broadly flat, while reported claims rose nearly 40% to almost 50,000. Marsh reported a 5% average U.S. rate decline in the fourth quarter of 2024, the first quarterly decline after seven years of increases. These figures describe different measures: premium volume, policy counts, claims, and rates are not interchangeable. Greater strategic importance does not mean every buyer faces higher premiums or tighter capacity. See the NAIC 2025 report and Marsh’s market update.
How the CISO’s job is changing
From technical owner to enterprise-risk translator
The CISO increasingly has to connect architecture and controls to business consequences: what could happen, how likely it is, how controls affect the likelihood or impact, and what exposure remains. That means explaining scenarios such as prolonged downtime, restoration expense, fraud, regulatory response, litigation, contractual claims, and recovery costs—not merely reporting tool deployment.
Insurance adds another part to that conversation: which losses may be covered, which are excluded or capped, and what retentions, waiting periods, notice duties, or other conditions apply. The CISO should be able to explain the security implications, but policy interpretation belongs with counsel and placement advice with the broker.
From renewal questionnaire to continuous control assurance
A “yes” on an application is only as useful as its scope and evidence. The CISO must help establish what systems and identities are covered, who owns each control, what exceptions exist, and how performance is checked. A recurring evidence trail is more credible than a screenshot or an unqualified point-in-time assertion.
Useful records can include identity and access reports, endpoint coverage and monitoring reports, backup architecture and restore-test records, vulnerability-remediation metrics, penetration-test findings, tabletop exercise results, and documented exception approvals. They should make clear the relevant environment, date, owner, gaps, and remediation status.
From incident responder to claims participant
During an incident, the CISO may need to coordinate technical response with the broker, insurer, breach coach or panel counsel, forensic investigators, privacy counsel, communications teams, law enforcement, finance, and business leaders. Policy terms can include notice, cooperation, consent, or vendor provisions. The CISO should know those requirements before an incident, rather than discover them while systems are down.
This does not make the insurer the incident commander. The organization still owns its response and recovery. The CISO’s job is to preserve that operational ownership while coordinating with the insurer and meeting applicable policy conditions.
From budget advocate to security-and-insurability strategist
Underwriting feedback can help make the case for identity protection, backup resilience, managed detection, email security, vulnerability remediation, segmentation, and incident-response preparation. But a control may improve eligibility, terms, or the organization’s ability to explain its risk without producing a predictable premium discount. Carriers have different appetites, models, policy forms, and thresholds; measure value in reduced likelihood and impact, improved recovery, credible board reporting, and coverage fit—not price alone.
Controls underwriters may scrutinize—and evidence the CISO should have
| Area | Questions an insurer may ask | Evidence and common gaps |
|---|---|---|
| MFA | Where is multifactor authentication enforced: remote access, email, privileged accounts, critical applications, cloud administration, backups, and third parties? | Maintain coverage reports, exception lists, and ownership. “We have MFA” can conceal legacy protocols, service accounts, backup consoles, or emergency paths without it. |
| Privileged access | Are administrative accounts separate from everyday identities? Are credentials vaulted, access logged, and privileges reviewed or time-limited? | Show account inventories, approval and review records, logs, and break-glass controls. Shared, standing, dormant, or orphaned privileges are frequent blind spots. |
| EDR/MDR | Are endpoints, servers, and relevant cloud workloads covered, monitored, and supported by a response capability? | Show deployment coverage, alert triage and escalation processes, and handling of unmanaged or unsupported devices. Owning a product is not the same as operating effective detection and response. |
| Backups and recovery | Are copies isolated or immutable, protected by separate credentials and MFA, and tested for restoration? | Provide architecture, scope, restoration records, and recovery-time and recovery-point objectives. Backups that cannot be restored in time do not establish resilience. |
| Email and fraud | How are impersonation, account compromise, and payment redirection addressed? | Document email protections such as SPF, DKIM, and DMARC, monitoring, awareness practices, and payment controls such as dual approval and out-of-band verification. Fraud controls are not a substitute for ransomware defenses. |
| Vulnerability and exposure management | How are internet-facing assets found, critical issues prioritized, and emergency patches handled? | Keep asset inventories, remediation timelines, unsupported-system records, and approved, revisited exceptions with compensating controls. Include relevant third-party exposure. |
| Incident response | Can the company respond quickly, preserve evidence, and restore business operations? | Keep a current plan and call tree, decision authority, insurer and broker contacts, response-provider information, notification workflows, and tabletop and recovery exercise records. |
The point is not to build a file cabinet for an application. Each record should help the organization understand whether a control works across its real environment. For instance, the meaningful backup claim is not merely that immutable storage exists; it is that critical systems are covered, production credentials cannot casually alter the copies, and restoration has been tested against business recovery objectives.
Working across finance, legal, the board, and insurance
With the CFO and finance team
Model plausible loss scenarios together: revenue interruption, lost productivity, extra expense, restoration, fraud, ransom or negotiation costs where lawful and covered, notification, regulatory and legal expense, and contractual penalties. Compare the result with retentions, sublimits, waiting periods, and the policy limit. A headline limit is not the same as the amount available for every cyber loss.
With general counsel
Ask counsel to review policy wording, notice and consent requirements, exclusions, regulatory coverage, contractual liability, sanctions restrictions, ransom-payment limits, and the consequences of inaccurate application statements. Legal obligations to regulators, customers, or counterparties may arise independently of insurance. For U.S. public companies, the SEC rule generally requires disclosure of a material cybersecurity incident within four business days after determining it is material, subject to the rule’s requirements and exceptions; it is not simply four days from the breach. SEC rule announcement.
With the board and executive team
Report material security gaps, changes in coverage and retentions, significant sublimits or exclusions, progress on insurer-relevant controls, and plausible losses that remain uninsured or only partly insured. The more useful board question is: Which plausible cyber losses remain uninsured or only partially insured, and what are we doing about them?

Run a controlled, cross-functional application process. The CISO is often a key contributor, but infrastructure, identity, finance, legal, procurement, and business owners hold facts the security team may not. A practical sequence is:
Best Value
- Obtain the correct application and policy wording for the relevant policy period.
- Map each question to a knowledgeable control owner and define ambiguous terms and scope.
- Collect evidence for each affirmative answer; record exceptions, compensating controls, and remediation dates.
- Validate technical answers with the teams that operate the systems, then review with legal, finance, risk, and the broker.
- Retain the submitted application and supporting records.
- Set a process to reassess material changes during the policy period, including acquisitions, migrations, staff changes, and control degradation.
Inaccurate or incomplete representations can create coverage disputes or other adverse consequences, depending on the application, policy, governing law, and facts. That is why an application should not be treated as a sales form or a security team’s solo certification.

Insurance can bring executive attention to foundational controls, create a deadline for documenting weaknesses, provide access to response expertise, and support investment proposals. A Sophos survey reported that 99.6% of surveyed organizations that invested in improving cyber defenses said those investments had a positive effect on their insurance position. That is vendor-commissioned research, not proof that a specific control will improve every company’s price or terms. Sophos’s survey summary.
The risk is checkbox security: allocating effort to whatever appears on a form while neglecting the organization’s actual attack paths, business dependencies, or recovery bottlenecks. A binary question can obscure partial deployment; an insurer’s preferred provider may duplicate an existing capability or be a poor technical fit. Bundled products and services—such as offerings that pair coverage with monitoring, risk dashboards, training, or advisory support—are available from some carriers, not universally. Assess their technical depth, service levels, data access, privacy, response authority, integration, independence during a claim, and portability before accepting them.
Recommended Free Tools
Treat insurance as one part of risk treatment: reduce risk with controls, avoid unacceptable exposure, accept residual risk deliberately, transfer selected financial consequences, and prepare to respond and recover. A policy cannot replace security leadership, sound architecture, identity governance, business context, or tested recovery. Nor does a policy limit guarantee that every loss up to that amount is covered: definitions, retentions, exclusions, sublimits, waiting periods, and conditions matter.
A renewal and readiness checklist
- Start early: leave time to resolve evidence gaps and compare coverage rather than rushing to meet a deadline.
- Read the actual form: review application questions and policy wording, not only the broker’s summary or last year’s answers.
- Map scope: identify the systems, identities, business units, subsidiaries, and suppliers implicated by each answer.
- Name owners: assign technical evidence to the teams that operate the relevant controls and keep exceptions visible.
- Test operation: verify endpoint coverage, privileged access, MFA scope, restore capability, response plans, and remediation practice.
- Model residual exposure: compare realistic scenarios with limits, retentions, sublimits, waiting periods, and exclusions.
- Review with specialists: use counsel for legal interpretation and the broker for placement and market options.
- Revisit between renewals: assess major business or technology changes and material control failures; do not assume last year’s application remains true.
What good CISO leadership looks like now
The CISO remains accountable for building security that fits the organization’s threat model, but the role increasingly includes enterprise-risk translation, control assurance, recovery planning, executive communication, and participation in insurance decisions. Smaller organizations may distribute these duties among an owner, CFO, IT manager, managed service provider, broker, or vCISO; the governance need remains even without a dedicated CISO title.
The right outcome is not merely a favorable renewal. It is a security posture the organization can demonstrate, a recovery capability it has exercised, a policy it understands, and a conscious decision about the financial risk left behind.
