Cowbell’s Prime lineup ranges from admitted SME products to non-admitted options for larger or advanced digital risks, with coverage and issuing insurer varying by Prime product. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeOne-Overview.pdf "Prime One Product Overview")

## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. [1](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

[Aon profile](https://spot.insure/insurance-providers/aon)

## What Is Cowbell Insurance?

Cowbell suits small and midsize businesses seeking cyber options by company size, with technology E&O and Zurich management-liability options also available; firms needing broad commercial coverage should compare a full-service broker. Some security services cost extra. [4](https://cowbell.insure/ "Cowbell") [5](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [6](https://www.zurichna.com/insurance/excess-and-surplus/small-business-management-liability "Small And Midsize Business Management Liability")

## 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

### Product tiers, insurers and limits

Aon says cyber terms vary and frames its role as reviewing policy options. Cowbell offers Prime 100 and 100 Pro for SMEs, Prime 250 up to $1 billion revenue and Prime One for advanced exposures typically above $250 million; carrier paper varies by product. Cowbell lists limits up to $3 million for Prime 100 Pro endorsements and up to $10 million for select Prime One risks, while base limits are not published for some tiers. Buyers should identify the exact Prime form and insurer. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview")

### Security services and agent access

Aon describes claims advocacy and third-party incident-response relationships under separate contracts. Cowbell says each Prime policy includes risk ratings, resilience services, integrations and Wizer awareness training, and distributes through appointed agents. Some Prime 100 policies can be quoted and bound quickly by agents. Ask what services attach to your tier and whether an agent can submit your account through that route. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview")

## What to Confirm in Cyber Insurance Quotes

- Ask Cowbell to identify the Prime tier, insurer, base and endorsement limits, and whether your revenue or digital exposure changes eligibility. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview")
- Ask Aon who contracts with response partners; ask Cowbell which security services and training remain available throughout the policy term. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview")

## Offering Details

| Criteria | Aon Cyber brokerage and risk-advisory offering | Cowbell Prime Cyber Insurance (Prime 100, Prime 100 Pro, Prime 250, Prime One, Prime Plus) |
| --- | --- | --- |
| Role in This Line | Aon describes cyber insurance brokerage and risk-advisory services. It is not identified as the risk-bearing insurer, and the global page does not name the carrier for a particular placement. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: Aon’s official global product/capability page. The statement is limited to Aon’s marketing of brokerage or advisory services, not policy issuance..) | 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. [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [9](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime250-Overview.pdf "Prime 250 Product Overview") [10](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..) |
| Issuing Insurer | The reviewed page does not identify the insurer or the legal producing entity for a specific placement. Ask Aon to identify both for the quoted risk. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Not found in reviewed sources; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote, binder or policy was reviewed. This does not establish that no insurer or producing entity is available..) | 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. [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [9](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime250-Overview.pdf "Prime 250 Product Overview") [10](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..) |
| Who It’s For | Aon describes cyber services for organizations managing cyber risk. Its global practice page does not publish a complete industry, revenue, security-control or state-by-state eligibility schedule. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: Audience stated by Aon on its global capability page; this does not establish a specific applicant’s eligibility or placement availability by U.S. state..) | Cowbell markets Prime 100 (admitted) to SMEs with up to $100M in revenue, Prime 100 Pro (admitted, available in 47 states) to a similar SME band with broader endorsements, Prime 250 (non-admitted) to businesses up to $1B in revenue, and Prime One (non-admitted) to organizations with more advanced digital exposure, typically $250M+ in annual revenue. [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100Pro-Overview.pdf "Prime 100 Pro Product Overview") [9](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime250-Overview.pdf "Prime 250 Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeOne-Overview.pdf "Prime One Product Overview") (Evidence: Company-reported; scope: Risk Appetite sections of each PDF..) |
| Coverage Features | Aon describes cyber insurance as one part of cyber risk financing and says it reviews policy offerings because terms and conditions vary. For professional-services firms, it discusses coordinating cyber and professional-liability coverage. This is brokerage guidance and does not establish the terms of any cyber policy. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: Aon’s broker-authored explanation of the insurance line. It does not establish an individual insured’s policy entitlement; the insurer’s form, endorsements and declarations control..) | 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. [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [10](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..) |
| Limits and Retentions | The reviewed page does not state a standard buyer-specific limit, retention or deductible for this placement. Confirm amounts, sublimits and conditions in the quote and issued policy. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Not publicly disclosed; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote or policy form was reviewed..) | 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. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100Pro-Overview.pdf "Prime 100 Pro Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeOne-Overview.pdf "Prime One Product Overview") [11](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..) |
| Risk Services | Aon describes cyber claims advocacy and preparation and relationships with third-party incident-response providers. The retained official source notes that provider contracts are separate, no performance guarantee is made, and referral remuneration may occur; confirm the providers, scope and compensation applicable to a client. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: Company-reported brokerage and advisory services. Account-specific service terms are not stated..) | 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. [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [9](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime250-Overview.pdf "Prime 250 Product Overview") (Evidence: Company-reported; scope: 'The Cowbell Advantage' section, repeated across the reviewed product PDFs..) |
| How to Apply | Confirm in your quote. | 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. [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") [8](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..) |
| Claims Support | Confirm in your quote. | Cowbell says its in-house cyber claims team has over 80 years of combined claims-handling experience and provides 24/7 in-house claims support from initial triage through resolution. [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeOne-Overview.pdf "Prime One Product Overview") [7](https://cowbell.insure/wp-content/uploads/pdfs/CB-Prime100-Overview.pdf "Prime 100 Product Overview") (Evidence: Company-reported; scope: Prime One 'When an incident occurs' section and 'Expert Claims Support' feature repeated across the product PDFs..) |
