## Summary

Aon describes professional-liability structures tailored to professional firms. CFC’s Professional Services policy combines E&O with optional GL, property and cyber, with brochure limits up to $10 million for E&O. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States")

## 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")

## What Is CFC Insurance?

CFC fits technology businesses seeking one eligible package for E&O, cyber, media/IP and general liability; buyers wanting to bind directly online should compare other routes. Its cyber policies may also include 24/7 incident support. [4](https://www.cfc.com/en-us/company/ "About CFC") [5](https://www.cfc.com/en-us/products/industry/technology/ "Technology") [6](https://webcdn.cfc.com/media/ywdbvkpy/technology_product-brochure_us_0525_v2.pdf "Technology — United States product brochure") [7](https://www.cfc.com/en-us/support/regulatory-information/ "Regulatory information")

## What Is Professional Errors and Omissions (E&O) Insurance?

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [11](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [12](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [13](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [14](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### Form and Coverage Scope

Aon says it tailors professional-liability coverage structures to firm needs but publishes no specific form terms. CFC describes a modular Professional Services policy that pairs E&O with optional general liability, property and cyber. Its stated E&O scope includes breach of contract, bodily injury, property damage, subcontractor liability, IP infringement, pollution, defamation, document loss and withheld fees. Ask whether those extensions fit your services and how they interact with other coverage. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States")

### Buyer Fit and Policy Terms

CFC’s brochure lists E&O limits up to $10 million, a minimum deductible of zero and no revenue threshold, while also naming favored and ordinarily declined occupations. Aon does not publish a limit or profession schedule in its overview. CFC’s public pages do not name the risk-bearing insurer; Aon’s carrier varies by placement. Confirm profession eligibility, insurer, deductible and which optional parts are selected in the quote. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask CFC whether your occupation is favored or declined and which carrier appears on the declarations. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States")
- Ask Aon for comparable E&O limits, exclusions and whether GL, property or cyber are separate. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States")

## Offering Details

| Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | CFC Professional Services |
| --- | --- | --- |
| Role in This Line | Aon presents Professional Liability / E&O as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) | CFC sells professional errors & omissions as a modular package policy it calls "Professional services" (branded on the brochure as "Miscellaneous professional liability"), which pairs E&O with optional general liability, property and cyber add-ons rather than selling E&O alone. [8](https://www.cfc.com/en-us/products/class/professional-liability/ "Professional liability") [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States") (Evidence: Company-reported; scope: Professional liability product page's "Professional services" tile and the miscellaneous professional liability brochure..) |
| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement..) | The reviewed professional liability page and brochure describe CFC as the policy designer and point of contact but do not name the insurer that carries the risk for this product. [8](https://www.cfc.com/en-us/products/class/professional-liability/ "Professional liability") [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States") (Evidence: Not publicly disclosed; scope: Professional liability product page and professions brochure as read on 2026-09-23. CFC's own materials describe it as an underwriting manager rather than a risk-bearing insurer, so a specific carrier for this product would need to come from the quote or declarations..) |
| Who It’s For | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) | CFC says it favors business, educational, environmental, food, HR, market-research, quality-assurance, security and traffic consultants, event organisers, freight brokers, loss adjusters, private investigators and trade associations, and ordinarily declines debt collectors, financial advisors, health and safety consultants, insurance agents, lawyers, mortgage brokers, pre-purchase home inspectors, stockbrokers, tour operators and valuers. [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States") (Evidence: Company-reported; scope: Brochure's "What we love" and "What we ordinarily decline" lists; actual acceptance depends on individual underwriting..) |
| Coverage Features | Aon describes professional liability as addressing professional-services firms’ liability exposure and says it tailors coverage structures to a firm’s needs. It identifies E&O as a commonly used name for professional-liability insurance; actual policy terms are not stated. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage..) | CFC says the E&O cover includes breach of contract, bodily injury, property damage, vicarious liability of subcontractors, IP infringement, pollution liability, libel, slander, defamation, document loss and withheld fees, with worldwide legal cover. [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States") (Evidence: Company-reported; scope: Brochure's "Comprehensive errors & omissions cover" and "Comprehensive legal cover" sections; exact wording and exclusions are set by the policy as issued..)<br><br>Businesses can add a separate commercial general liability limit, property, and cyber and privacy liability to the E&O policy, plus optional umbrella liability that sits over the E&O and CGL layers. [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States") (Evidence: Company-reported; scope: Brochure's "Modular package policy" and "Umbrella liability" sections; availability depends on underwriting..) |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) | CFC's brochure lists maximum limits of $10,000,000 for E&O, $6,000,000 for CGL and $5,000,000 for umbrella, with a $0 minimum deductible, minimum premiums starting at $475-$500 depending on the coverage part, and no revenue threshold for eligibility. [9](https://www.cfc.com/media/n0sbwydf/professions_product-brochure_us_0825.pdf "Miscellaneous professional liability | Product brochure | United States") (Evidence: Company-reported; scope: Brochure's "Limits, deductibles, premiums, revenue threshold" section; the terms actually issued depend on underwriting..) |
| Risk Services | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) | Confirm in your quote. |
| How to Apply | Confirm in your quote. | CFC publishes a dedicated application form for this policy and also says its professional liability class can be traded directly through its Connect platform or through named API partners, in addition to the standard broker-submitted application. [8](https://www.cfc.com/en-us/products/class/professional-liability/ "Professional liability") (Evidence: Company-reported; scope: Professional liability product page's downloads and "Digitally traded" sections; not confirmed specifically for the professions/miscellaneous professional liability product versus the class as a whole..) |
| Claims Support | Confirm in your quote. | CFC lists a named Claims Manager for Professions on its claims team, indicating professional-liability claims are routed to a dedicated professions unit rather than a generalist adjuster. [10](https://www.cfc.com/en-us/claims/ "Claims") (Evidence: Company-reported; scope: CFC's claims page team listing; the page does not publish claim volumes or turnaround times specific to this product..) |

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.
