## What Is Cyber Insurance?

Cyber insurance can help pay covered response costs and claims against your business after a cyber incident. If your business relies on data, software or outside providers, compare response limits, vendor outages and approval rules. [12](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [13](https://www.aig.com/content/dam/aig/america-canada/us/documents/business/cyber/cyberedge-wording-sample-specimen-form.pdf "CyberEdge specimen policy")

## Key Differences in Cyber Insurance

### Coverage and Limits

Cowbell’s Prime products span SMEs through larger organizations: Prime 100 and Pro target up to $100 million revenue, Prime 250 up to $1 billion, and Prime One typically $250 million-plus with more advanced exposure. Marsh McLennan Agency describes organizations managing cyber risk but gives no thresholds. Ask Marsh McLennan Agency which market can fit your revenue and digital profile. [4](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Security Services and Eligibility

Cowbell says Prime 100 includes social engineering, hardware replacement, interruption, extortion, computer and funds-transfer fraud, and electronic-data restoration; Prime One adds affirmative AI and quantum incident coverage. Limits vary by product, including up to $10 million for select Prime One risks. Marsh McLennan Agency does not list these grants or limits. Ask for specific wording and sublimits. [4](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Buying and Incident Support

Cowbell distributes through appointed agents and provides risk ratings, resilience guidance, security integrations and first-year Wizer training. It says agents can issue Prime 100 in under five minutes, while Marsh McLennan Agency invites an adviser discussion. Cowbell’s issuer varies by Prime product, so verify the carrier on the quote. [4](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

## What to Confirm in Cyber Insurance Quotes

- Which Cowbell Prime tier, carrier and limits fit your revenue and AI exposure? Ask Marsh McLennan Agency to identify available cyber-crime grants, included resilience services and quote timeline.

| --- | --- | --- |
| Role in This Line | Cowbell operates as an insurance agency that markets its own named 'Prime' cyber product line, rather than distributing another carrier's off-the-shelf policy under its own brand. [4](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [6](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime250-Overview.pdf "Prime 250 Product Overview") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeOne-Overview.pdf "Prime One Product Overview") (Evidence: Company-reported; scope: Product overview PDFs for Prime 100, Prime 100 Pro, Prime 250, Prime One and Prime Plus..) | Marsh McLennan Agency describes arranging cyber for the audience stated on the cited product page. [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") (Evidence: Company-reported; scope: cyber marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Issuing Insurer | Cowbell says Prime 100 and Prime 100 Pro paper is provided by Palomar Specialty Insurance Company (AM Best A rating), Prime 250 by Palomar Specialty Insurance Company and Chaucer Insurance Company, and Prime One by Chaucer Specialty Insurance Company; the insurer therefore varies by which Prime product is placed. [4](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [6](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime250-Overview.pdf "Prime 250 Product Overview") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeOne-Overview.pdf "Prime One Product Overview") (Evidence: Company-reported; scope: Footer/underwriting statements in each product PDF..) | Confirm in your quote. |

[11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") (Evidence: Company-reported; scope: cyber marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Coverage Features | Base Prime 100 coverages include security breach liability, social engineering, hardware replacement, business income and extra expense, extortion threats, computer and funds transfer fraud, and restoration of electronic data; Prime One adds affirmative AI-incident and quantum-computing-incident coverage for more advanced digital exposures. [4](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeOne-Overview.pdf "Prime One Product Overview") (Evidence: Company-reported; scope: Prime 100 Coverages and Prime One 'Emerging risk coverage' sections; illustrative, subject to the issued policy's terms..) | The cited product page describes cyber liability and a cyber-risk management strategy as part of the executive and professional risk offering. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction.

This is not a policy form or a universal eligibility statement..) |
| Limits and Retentions | Cowbell states Prime 100 Pro adds endorsements with limits up to $3M, Prime One offers limits up to $10M for select risks, and Prime Plus is an excess layer offering up to $5M above a primary cyber policy; base Prime 100 and Prime 250 limit figures are not published in the reviewed PDFs. [5](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100Pro-Overview.pdf "Prime 100 Pro Product Overview") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeOne-Overview.pdf "Prime One Product Overview") [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimePlus-Overview.pdf "Prime Plus Product Overview") (Evidence: Company-reported; scope: Product overview PDFs; actual issued limits depend on underwriting..) | The cited overview does not set a universal limit or retention for this line. Ask for the proposed policy form, limits, retentions, exclusions, and conditions in the quote. [11](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") (Evidence: Not publicly disclosed; scope: Only the cited marketing page was reviewed for published limit and retention information; no policy-form entitlement is inferred..) |
| Risk Services | Cowbell says every Prime policy includes Cowbell Factors risk ratings, Cowbell Resiliency Services, Cowbell Insights guidance, Cowbell Connectors integrations with cloud/security providers, and complimentary Wizer cybersecurity-awareness training with unlimited seats in the first policy year.

| How to Apply | Cowbell says agents can quote, bind and issue Prime 100 policies in less than five minutes, and that Prime 100 Pro requires only six underwriting questions for accounts under $50M in revenue; Prime products are distributed through appointed agents rather than direct to consumers. [4](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [5](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100Pro-Overview.pdf "Prime 100 Pro Product Overview") (Evidence: Company-reported; scope: Prime 100 and Prime 100 Pro overview PDFs; speed figures are company-reported, not independently timed..) | The page invites organizations to contact a Marsh McLennan Agency adviser or specialist to discuss placement.
