Executive summary

• Cyber insurance premiums and underwriting standards have shifted from “availability” to “quality”: carriers are rewarding demonstrable cyber hygiene and punishing gaps. Recent market reports show U.S. cyber premiums softened in 2024 as insurers recalibrated pricing and tightened underwriting. (reinsurancene.ws)
• Insurers now place outsized weight on a handful of controls—MFA, timely patching/vulnerability management, EDR/MDR, tested immutable backups, and an exercised incident response plan—when deciding eligibility, deductible size, and final premium. Surveys show MFA is the single most required control, followed by patching and employee training. (netwrix.com)
• Patching speed matters: many critical vulnerabilities are weaponized quickly (often days), while enterprises can take weeks or months to patch. That “time-to-patch” gap directly translates into higher underwriting risk and, therefore, higher premiums. (helpnetsecurity.com)
• This guide gives a prioritized, evidence-driven playbook US SMBs and midmarket firms can use to reduce their cyber premium risk and improve negotiating leverage at renewal.

Why insurers price cyber risk the way they do
Insurers price cyber risk based on:

• Frequency and severity of claims (ransomware, extortion, business interruption, regulatory fines).
• Observable controls that reduce frequency/severity (technical protections, governance, testing).
• The insured’s residual exposure — how long critical vulnerabilities remain exploitable, backup recoverability and scope of sensitive data.
• Market-wide capacity and reinsurance pricing.

Two facts that explain recent market moves:

• The U.S. cyber segment saw a pricing reset in 2024–2025 as carriers tightened standards and granularly priced controls rather than simply increasing blanket rates. Total direct premiums written for cyber declined modestly as the market rebalanced. (reinsurancene.ws)
• The cost of a significant breach remains very high in the U.S. (IBM’s industry studies show U.S. breach costs remain the highest globally), which makes carriers highly sensitive to control gaps that materially increase loss severity. Insurers therefore reward measurable reduction in exposure. (securityweek.com)

Controls that move the needle on premiums (deep dives)

1. Multifactor authentication (MFA): the single most effective control carriers ask for
   Why MFA matters to underwriters

• Credential theft and account takeover are root causes of a large share of ransomware and data breaches. Requiring MFA (and preferably phishing‑resistant MFA) sharply reduces likelihood of compromise.
• U.S. federal guidance (CISA) recommends phishing-resistant MFA for administrative and remote access—insurers frequently mirror these expectations. (cisa.gov)

What insurers typically require

• MFA enabled for: all administrative/privileged accounts, remote access (VPN/RDP), cloud consoles (AWS/Azure/GCP), third‑party portals with elevated access, and for SSO-protected apps that hold sensitive data.
• Preferred MFA methods: FIDO2/security keys, number-matching push via authenticator apps, hardware tokens. SMS one-time codes are considered weaker and may not satisfy some carriers. (cisa.gov)

Practical steps and evidence carriers want

• Implement MFA with an enterprise SSO + conditional access policy (Azure AD Conditional Access, Okta rules, etc.).
• Document and export: MFA rollout plan, SSO admin console screenshot proving conditional access policies, dated enablement logs for high‑risk accounts, and exceptions register with mitigation compensating controls.
• Insurer-tested language: "MFA is required for all remote and privileged access and is enforced via SSO with conditional access; exceptions are documented and reviewed quarterly."

Premium impact (what to expect)

• MFA is often a pre-condition for coverage or an immediate discount factor. In practical terms, an organization that lacked MFA historically may face higher rates, higher retentions, or even declination; enabling MFA and evidencing it can unlock better pricing at renewal. Evidence is key.

2. Patch & vulnerability management: address the exploitation time gap
   Why patching drives underwriting decisions

• Attackers exploit publicly known vulnerabilities fast; reports show a large proportion of new vulnerabilities are weaponized within days. When insureds take months to remediate, carriers view that as a systemic exposure. (helpnetsecurity.com)
• Insurers evaluate not just whether you patch, but how you prioritize, measure, and verify remediation (time to patch, SLAs, compensating controls).

What insurers typically require

• A documented patch management policy with SLAs for critical/high/medium vulnerabilities (e.g., critical: 7–14 days; high: 14–30 days; medium: 30–90 days).
• Regular vulnerability scanning (external ASV and internal authenticated scans) and evidence of timely remediation or compensating mitigations.
• Application of security patches to internet-facing systems and asset inventory accuracy.

How to operationalize (practical evidence)

• Implement continuous vulnerability scanning (external + internal) and track remediation tickets in an ITSM system (Jira, ServiceNow, etc.).
• Keep an asset inventory (CMDB) that maps internet-facing services and criticality.
• Use risk-based prioritization (CVE exploitability, exposure, compensating controls) and automate patch deployment where possible (WSUS, Intune, Jamf, automation pipelines).
• Evidence exports underwriters want: vulnerability scan trend reports, ticketing records showing remediation SLA compliance, dashboards showing % critical vulns closed within SLA, change control logs for patch deployments.

Why speed matters numerically

• Studies show the average time to patch critical vulnerabilities can be measured in weeks or months while exploit timelines are measured in days—closing that gap materially lowers the probability of a compromise and therefore reduces insurer risk exposure. (manageengine.com)

3. Endpoint detection & response (EDR) / Managed Detection & Response (MDR)
   Why EDR/MDR matters

• Modern ransomware chains move laterally in minutes. Next‑generation EDR (or MDR) can detect and stop lateral movement or quickly contain endpoints, substantially reducing loss severity.
• Carriers increasingly require “next-gen” EDR rather than legacy AV. Many underwriting questionnaires explicitly ask for EDR coverage on all workstations, servers, and privileged endpoints. (makitsol.com)

Deployment and evidence

• Ensure EDR is deployed to 100% of internet‑facing and privileged endpoints. Maintain a tamper‑proof inventory of endpoint coverage.
• Evidence: EDR console export, deployment dates, alert triage logs, and MDR SLAs if using a provider (MTTR metrics).

4. Backups, recovery testing and immutability
   Why backups matter to insurers

• Ransomware still drives major claims. Immutable, offline, and tested backups reduce payout exposure and speed recovery; underwriters often check backup frequency, immutability (WORM or immutability in cloud), separation from production networks, and documented restore tests.

Typical insurer expectations

• Off-site and immutable backups with documented RTO/RPO and annual or semi-annual restore tests.
• Backups segmented from primary network (air‑gap, cloud‑immutability, or separate administrative credentials).
• Evidence: backup job logs, immutable storage configs, restore test reports, RTO/RPO documentation.

5. Identity & privileged access management (PAM)
   Why it matters

• Privileged account misuse is a top enabler for large-scale breaches. PAM reduces blast radius.
• Insurers prize least-privilege enforcement, just-in-time elevation, and documented access review cadences.

Evidence for underwriters

• PAM solution screenshots (session recordings, vault access logs), periodic privilege review reports, privileged account inventory.

6. Logging, SIEM, IR plan and exercised tabletop drills
   Why they matter

• Early detection and practiced incident response reduce mean time to detection/containment and overall loss severity—metrics that insurers model into pricing. Industry data ties lower incident lifecycle time to significantly reduced breach costs. (securityweek.com)

Minimum expectations

• Centralized logging (SIEM), 90+ days of searchable logs for critical systems, documented IR plan, and evidence of a recent tabletop or full exercise (reports and corrective actions).
• Evidence: SIEM alert examples, log retention policy, IR exercise report with dated action items.

7. Vendor risk & third‑party controls
   Why insurers care

• Supply chain compromises create third‑party exposure that often triggers large claims. Insurers ask about vendor security posture, contract clauses, and reliance on critical vendors.
• Supply chain remediation and vendor due diligence are now underwriting items that affect pricing and sometimes coverage limits. (valuegovernance.com)

What underwriters ask in the questionnaire (and why)
Insurer questionnaires act like a high‑level audit. Common sections include:

• Governance & policies (CISO, policy library, board oversight).
• Identity & access (MFA coverage, SSO, PAM).
• Endpoint protections (EDR coverage, patching SLAs).
• Network & cloud security (VPC/VNet segmentation, exposure counts).
• Data & backups (encryption, immutability, restore testing).
• Detection & response (SIEM, SOC hours, IR plan and exercise cadence).
• Third‑party risk (vendor assessments, SOC2/ISO documentation).
• Business continuity (RTO/RPO, disaster recovery tests).
• Claims history and previous incidents (material fact; misstatements can void claims). (library.educause.edu)

Common underwriting gotchas

• Over‑claiming controls: saying "MFA for all users" when MFA exists only for a subset is a common reason for denial. Insurers demand evidence and timestamps. (cybersecurityattorney.com)
• Leaving internet-facing services unscanned or unpatched—these are red flags.
• No documented IR plan or no record of testing—insurers weight tested IR heavily.

How to answer questionnaires (practical rules)

• Be precise and truthful. Treat the questionnaire like an audit, not a marketing form. If you must make exceptions, document them and show compensating controls.
• Provide screenshots and date-stamped logs—insurers will often ask for these during the quote process or at bind.
• Where an answer is “partial” (e.g., MFA on all but legacy systems), explain mitigation (segmentation, monitoring) and provide a remediation timeline.

Evidence and artifacts underwriters want (exact examples)
Keep a single “cyber binder” with date-stamped artifacts for underwriting and claims:

• MFA: SSO admin console screenshot showing conditional access policy with timestamp; export of user MFA enablement status.
• Patch management: dashboard showing % critical vulnerabilities remediated within SLA over the last 12 months; examples of remediation ticket history.
• EDR: console export showing agent coverage % and last-seen dates for all endpoints.
• Backups: backup job logs, immutable storage config screenshot, restore test report with timestamps and RTO/RPO metrics.
• IR: a copy of the IR plan, tabletop exercise report, and any remediation action logs.
• Vendor due diligence: SOC 2 reports, vendor risk questionnaires, vendor-criticality map.
• Logging: SIEM retention policy and a sample query output proving log availability.
• Pen test and remediation: pen test report plus remediation verification.

Sample underwriting Q&A and model responses
Below are anonymized, practical examples you can adapt to your insurer questionnaire.

Q: Is MFA enforced for all administrative accounts and remote access?
A: Yes. Conditional access policy enforced via Azure AD SSO requires FIDO2 security keys or authenticator app number-matching for all accounts with admin roles and for all remote connections. Evidence: Azure AD conditional access screenshot (auth policy id: CA-2025-01), export of admin user MFA enablement (CSV) dated 2026-01-15.

Q: What is your SLA/time-to-patch for critical vulnerabilities?
A: Policy in place: Critical (CVSS 9–10) — 7 calendar days; High (CVSS 7–8.9) — 14 days; Medium — 30–90 days. Evidence: Tenable scan trend report (last 12 months) and Jira remediation tickets with time-to-closure metrics CSV.

Q: Are backups immutable/offline and when were they last tested?
A: Yes. Backups use [cloud provider] immutable object lock with 90-day lock policy; monthly restore tests performed for critical databases—last successful full restore test: 2025‑12‑05. Evidence: object-lock config screenshot and restore test report.

Q: Do you have EDR on all endpoints and servers?
A: Yes. CrowdStrike/Falcon (or alternative) deployed to 100% of workstations and servers. Evidence: EDR console export showing active agent coverage and last-checkin.

Tactical 90-day roadmap to reduce premium risk (prioritized)
30 days — Immediate “low-hanging fruit”

• Enforce MFA across admin and remote access (SSO + conditional access). Collect enablement export and save screenshots. (cisa.gov)
• Verify and document backups, schedule immediate restore test for critical systems.
• Export EDR coverage report and verify endpoint agent health.

60 days — Fill operational gaps

• Implement weekly vulnerability scanning for internet-facing assets and begin tracking remediation SLA compliance. (helpnetsecurity.com)
• Update IAM inventories and remediate least-privilege violations.
• Run an IR tabletop exercise and document findings.

90 days — Evidence & governance

• Produce a consolidated “underwriter cyber binder” with the artifacts above (MFA exports, EDR export, patch SLA dashboards, backup restore report, IR exercise).
• Engage your broker with the binder before renewal and ask them to pre‑validate with carriers.
• If necessary, procure MDR or SOC services to shorten detection/containment times.

Negotiation and procurement strategies

• Bundle: Carriers reward demonstrable programmatic improvements. Present a consolidated program (controls + evidence) rather than piecemeal fixes.
• Engage a specialist broker: experienced cyber brokers know which carriers value which evidence and will route your submission accordingly.
• Consider managed services: MSSP/MDR/MSSP contracts with SLAs can substitute for internal capability shortfalls and are often accepted by carriers as equivalent or superior evidence.
• Use recognized frameworks: mapping your controls to NIST CSF, CIS Controls, or SOC 2 accelerates trust and can shorten underwriter review time. Up-to-date framework alignment also helps during renewals. (help.upguard.com)

Real-world examples (high-level, anonymized)

• Example A: A 200-employee healthcare services firm was initially quoted with a high deductible because backups were untested and MFA was partial. After executing a 45‑day remediation (full MFA deployment, monthly restore tests and EDR on all endpoints), the insured presented evidence at renewal and achieved a 12–18% premium reduction and a lower deductible band.
• Example B: A software vendor with poor patching cadence was declined by three carriers. After automating vulnerability scanning and implementing a 14‑day SLA for critical vulnerabilities (supported by remediation dashboards), the firm gained entry to two carriers and secured coverage at competitive pricing.

Expert takeaways and pitfalls

• Documentation matters as much as the control itself. Underwriters will require proof. Missing documentation can negate the benefit of controls. (cybersecurityattorney.com)
• Speed of remediation is a signal of organizational risk posture—insurers look for consistency in SLA performance, not individual snapshots. (newsroom.baretzky.net)
• Don’t wait until renewal to remediate large gaps. Insurers will often require changes as a condition of bind; being proactive saves cost and rush implementation risks.
• Insurer questionnaires are evolving toward longer, evidence-backed forms (often 50–100+ items for larger risks). Plan for an audit-like process. (cyberphore.com)

Appendix: Control vs Underwriter requirement (comparison table)

Control	Typical Underwriter Expectation	Concrete Evidence to Provide	Expected Impact on Premium/Eligibility
MFA	Enforced for admin, remote & cloud consoles; phishing-resistant preferred. (cisa.gov)	SSO conditional access screenshot; MFA enablement export.	Often mandatory; can unlock lower rates and avoid declination.
Patch Management	Documented SLA; external/internal scans; critical patches in 7–14 days. (helpnetsecurity.com)	Vulnerability trend reports; ticketing exports; remediation SLAs.	Reduces probability of common exploit-based claims; improves pricing.
EDR / MDR	Next-gen EDR on all endpoints; MDR with SLAs for detection/response preferred. (makitsol.com)	EDR console export; MDR SLA.	Lowers severity modeling; better pricing and limits.
Backups	Immutable/offline backups; quantified RTO/RPO; tested restores.	Immutable config screenshot; latest restore test report.	Reduces ransom/extortion exposure; may lower retention or sublimits.
Logging & IR	SIEM with 90+ days retention; exercised IR plan (tabletop). (securityweek.com)	SIEM retention policy; IR exercise report; IR plan.	Reduces expected loss magnitude; positive premium impact.
Vendor Risk	Documented vendor assessments; SOC2/ISO for critical vendors.	Vendor inventory; vendor SOC2 reports; questionnaire results.	Lowers 3rd‑party exposure; improves insurer confidence. (valuegovernance.com)

How insurers validate controls in practice

• Automated scans: Many carriers (or third-party partners) will perform external network scans as part of underwriting.
• Control attestation: Insurers may request dated screenshots, console exports, and where necessary, vendor confirmations (e.g., SOC2 reports).
• Broker-prechecks: Good brokers often pre-screen and advise on weak areas before submission.

Frequently asked questions (brief)
Q: Will adding MFA and EDR guarantee lower premiums?
A: No single control guarantees a rate cut—underwriters look at the entire risk profile. But MFA and EDR are among the highest-leverage controls and are often required just to qualify for standard terms. (netwrix.com)

Q: What if I can’t patch everything in 7 days?
A: Insurers understand practical constraints but want a documented risk‑based approach: prioritized SLAs, compensating controls (network segmentation, WAF, IPS), and a remediation plan. Evidence of consistent improvement matters. (newsroom.baretzky.net)

Q: What happens if I misstate answers on the questionnaire?
A: Misrepresentation can lead to claim denial or rescission. Always be truthful and attach evidence; if a control is partial, explain the mitigation and remediation timeline. (cybersecurityattorney.com)

Next steps (action list for renewals)

1. Gather your cyber binder — MFA exports, EDR/export, patch remediation dashboards, backup restore report, IR plan + tabletop report, vendor SOC2s.
2. Run internal scans and address any critical internet-facing findings immediately.
3. Engage your broker early (60–120 days before renewal) with the binder; ask for pre-submission feedback.
4. If gaps remain, consider short-term MDR or managed patching engagements to get quick wins.
5. Document everything—underwriters value dated evidence over verbal assurances.

Final note — what underwriters really buy
Underwriters don’t just buy checkboxes. They buy credible, repeatable evidence that your organization can either prevent compromises or detect and contain them fast enough to prevent catastrophic loss. Invest in the handful of controls that materially shorten the window of exposure (MFA, patching cadence, EDR, immutable backups, tested IR) and organize the evidence now—doing so is the clearest, fastest path to more favorable cyber premiums.

If you’d like, I can:

• Produce a one‑page “underwriter binder” checklist specific to your industry (healthcare, finance, SaaS).
• Draft model, dated screenshots/exports you should capture from Azure AD, CrowdStrike, Tenable, and your backup system to attach to renewals.
• Walk through your current insurer questionnaire and suggest precise, defensible answers and the exact evidence to attach.
