### Who each practice serves

Ask which team handles renewals, policy changes and claim questions for your E&O account.

## Aon vs Vouch Professional Liability (E&O) Insurance Compared

| Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | Vouch Errors & Omissions Insurance |
| --- | --- | --- |
| 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..) | Vouch is a broker, not an insurer, for professional errors & omissions coverage. It lists Errors & Omissions among the core coverages it places for professional-services clients, and one of its named program partners, Corix, has a dedicated E&O product. [8](https://www.vouch.us/professional-services "Insurance for Professional Services Firms") [9](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") (Evidence: Company-reported; scope: Vouch's Professional Services page and Corix's cyber/E&O product page..) |
| 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..) | Corix's disclosures say its proprietary products, including its E&O line, are issued by State National Insurance Company or United Specialty Insurance Company. That names an insurer for Corix-branded E&O products specifically, not for every Vouch professional-liability placement. [10](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures") (Evidence: Company-reported; scope: Corix disclosures page..) |
| 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..) | Vouch markets professional E&O to accounting and finance, architecture/engineering/construction, IT consulting, management consulting, and marketing and creative agency firms. [8](https://www.vouch.us/professional-services "Insurance for Professional Services Firms") (Evidence: Company-reported; scope: Vouch's Professional Services page; not an underwriting appetite guarantee for any specific applicant..) |
| 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..) | Corix describes E&O as protecting a business against claims of negligence, mistakes or inadequate work that cause a client financial loss in the provision of professional services, including legal defense costs and any damages awarded, even when the claim is ultimately groundless. [9](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") (Evidence: Company-reported; scope: Corix's cyber and E&O product page; actual insuring agreements and exclusions are set by the issued policy..) |
| 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..) | Neither the Vouch nor Corix pages publish E&O policy limits or retentions. [8](https://www.vouch.us/professional-services "Insurance for Professional Services Firms") [9](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") (Evidence: Not publicly disclosed; scope: Pages checked on 2026-09-23..) |
