Insurance Curator Target audience: U.S.‐based CFOs, risk managers, and IT security leaders preparing to buy or renew cyber coverage in 2024.
Primary goal: Equip you with a proven, numbers-driven methodology for translating technical cyber threats into the hard dollar figures underwriters at Chubb, Hiscox, Travelers, and Coalition demand.
Why “Good Enough” Risk Estimates Fail in Today’s Insurance Market
According to the National Association of Insurance Commissioners (NAIC), the average standalone cyber premium in the United States jumped 62 % between 2021 and 2023, settling at $17,500 for a $1 M limit for mid-market buyers in cities such as Dallas and Denver.¹ Meanwhile, IBM’s 2023 Cost of a Data Breach Report pegs the average U.S. breach at $9.48 M.²
That gap—$17.5K in premium versus $9.48M in exposure—explains why underwriters have become laser-focused on quantitative risk analysis. Vague statements like “we have strong firewalls” or “MFA is in progress” simply won’t cut it.

1. What “Quantification” Actually Means
At its core, cyber-risk quantification converts technical threats (phishing, ransomware, supply-chain compromise) into Annualized Loss Expectancy (ALE) expressed in U.S. dollars. The typical equation:
ALE = (Probability of Event) × (Financial Impact per Event)
Underwriters cross-check your ALE against three underwriting levers:
- Retention (deductible)
- Sublimits and exclusions
- Premium price per $1,000 of limit
If your numbers look inflated or incomplete, expect higher retention and more exclusions.
2. Step 1: Map Critical Assets and Revenue Drivers
Underwriters focus on the assets that generate cash. Begin with a Business Impact Analysis (BIA) that links digital systems to revenue.
Asset Mapping Template
| Digital Asset | Supported Revenue Stream | Daily Gross Revenue | Compliance Impact (Yes/No) |
|---|---|---|---|
| e-commerce platform | Online sales (B2C) | $300,000 | Yes – PCI DSS |
| ERP (SAP S/4HANA) | Manufacturing orders | $1.2 M | Yes – SOX |
| Microsoft 365 | Workforce productivity | N/A | No |
Focus on:
- Systems that, if offline 24 hours, would cost >2 % of annual revenue
- Data subject to U.S. privacy laws (CCPA, GLBA, HIPAA)
Pro tip for U.S. buyers: In states like California, New York, and Texas, data privacy penalties stack quickly. Quantify regulatory fines separately.
3. Step 2: Identify Probable Loss Scenarios
Most carriers use scenario-based questionnaires. Align your list with the five dominant loss events:
- Ransomware extortion
- Business email compromise (BEC)
- Cloud misconfiguration data leak
- Third-party software supply-chain exploit
- Insider data theft
Scenario Library Example
| Scenario | Primary Asset | Primary Loss Type | Secondary Losses |
|---|---|---|---|
| Ransomware encrypts ERP | ERP | Lost revenue | Incident response, PR |
| BEC diverts payments | Microsoft 365 | Direct financial fraud | Legal, recovery fees |
4. Step 3: Assign Frequencies Using External Data
Underwriters rely on actuarial data; you should, too.
Source options:
- Verizon DBIR 2023 – Incident frequency by industry
- Secureworks Incident Response Report – Ransomware prevalence
- GovInfo NIST Vulnerability Database – CVE trending for your tech stack
Frequency Calculation Walk-through
- Suppose Verizon reports 86 ransomware incidents in manufacturing among 3,000 surveyed firms.
- Annual frequency = 86 / 3,000 = 2.9 %
- Adjust for your controls (MFA, EDR). If you meet the controls in From MFA to Backups: Technical Controls That Slash Your Cybersecurity Insurance Premiums, apply a risk reduction factor (commonly 0.4–0.6).
Example:
2.9 % × 0.5 = 1.45 % modeled frequency
5. Step 4: Estimate Financial Impact With Monte Carlo
Use a Monte Carlo simulation—1,000 to 10,000 iterations—to generate a loss distribution curve. Free tools include OpenFAIR and the RiskLens SaaS platform.
Inputs to capture:
- Direct costs: ransomware payment, forensics, legal fees
- Indirect costs: revenue loss, customer churn, share-price dip (for public firms)
- Regulatory fines: e.g., FTC, SEC, state AGs
Typical Cost Inputs (U.S. 2024)
| Cost Category | Low ($) | Mid ($) | High ($) | Source |
|---|---|---|---|---|
| Ransom demand | 75,000 | 350,000 | 6 M | Coveware Q2 2023 |
| Forensic IR | 25,000 | 125,000 | 500,000 | Deloitte |
| PCI fines (per record) | 50 | 150 | 250 | PCI Council |
Run the simulation; capture Mean, 90th percentile, and Max losses. Underwriters gravitate to the 90th percentile.
6. Step 5: Align Numbers to Carrier Underwriting Criteria
Carriers like Chubb and Hiscox publish risk-weighting models. Their levers often include:
| Factor | Weight in Premium Algorithm |
|---|---|
| MFA coverage | 15 % |
| External scan score | 20 % |
| Revenue size | 30 % |
| Quantified ALE | 25 % |
| Industry vertical risk | 10 % |
Translate your Monte Carlo output into these buckets. Example:
- ALE (90th percentile): $5.8 M
- Requested limit: $5 M
- Retention: $100K
You can now rationalize why $5 M is appropriate and prove that a $100K deductible keeps retained risk below 2 % of EBIT.

7. Step 6: Package Findings for the Application
Underwriting packets for U.S. markets (NY, IL, TX, CA) typically demand:
- Executive summary (1 page) – ALE, top five scenarios, control posture
- Quantitative appendix (Excel/PDF) – Monte Carlo details
- Policies & diagrams – Network, segmentation, backup flow
- Evidence-of-controls – MFA logs, EDR console screenshots
Submission Checklist
- Monte Carlo XLSX with assumptions tab
- Most recent SOC 2 or ISO 27001 report
- Backup restore test results within 90 days
- Zero-trust roadmap (if applying for preferred rates)
Carriers often give a 5–10 % premium discount when quantitative models accompany the submission.
8. Cost Benchmarks From Leading Carriers (Q1 2024)
| Carrier | Target Market | Typical Limit | Avg. Premium | Notable Requirements |
|---|---|---|---|---|
| Coalition | SMB ($5–250 M revenue) | $1–5 M | $5K–$35K | Continuous external scan; mandatory MFA |
| Chubb Cyber Enterprise Risk | Mid-market ($250 M–$1B) | $10–25 M | $120K–$400K | Segmentation report; IR retainer |
| Hiscox CyberClear | Tech & professional services | $1–10 M | $12K–$75K | Annual tabletop exercise |
| Travelers CyberRisk | Public companies | $25–100 M | $250K–$900K | SOAR implementation proof |
Pricing ranges are based on submissions in Atlanta, Chicago, and Austin in January 2024.
9. Case Study: Quantified Risk Spurs 22 % Premium Drop in Chicago
Company: Midwest Industrial Gear (private, $380 M revenue)
Location: Chicago, IL
Prior premium: $210,000 for $10 M limit (2023)
Challenge: Renewal quotes spiked to $280,000.
Actions Taken
- Implemented endpoint detection & response (EDR) and immutable backups.
- Conducted a Monte Carlo analysis: 10,000 simulations; 90th percentile loss = $7.8 M.
- Adjusted retention from $100K to $250K; reduced requested limit to $8 M.
- Packaged findings and control evidence.
Result
- Chubb counter-offered $219,000—a 22 % decrease from the projected $280K hike.
- Deductible increased, but retained risk remained <2 % of projected EBIT.
10. Take-Action Checklist
- Inventory high-value systems and tie them to dollar revenue.
- Define five loss scenarios aligned with carrier questionnaires.
- Pull frequency data from Verizon DBIR and adjust for your controls.
- Run Monte Carlo with at least 1,000 iterations; capture 90th percentile.
- Map outputs to carrier underwriting criteria (limit, retention).
- Compile submission packet with executive summary, quantitative appendix, and control evidence.
- Negotiate: Use your quantified ALE to argue for lower premiums or higher limits.
By grounding your application in hard numbers, you shift the conversation from “Do we have good security?” to “Here’s our modeled $ risk and how coverage closes the gap.” Underwriters reward that confidence with better terms.
