# Aon vs Corgi: How Do They Compare for Professional Liability (E&O) Insurance?

Aon tailors E&O structures for professional firms; Corgi treats miscellaneous E&O as a specialty quote separate from its instant-quote products.

## Research Scope and Use

Use this comparison to evaluate Aon and Corgi for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Aon describes tailored professional-liability structures for professional firms. Corgi offers a catch-all Miscellaneous E&O product for service businesses, usually quoted within one to fourteen days. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance")

## 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 Corgi Insurance?

Corgi suits technology startups wanting packages organized from pre-seed through growth, with dashboard changes as the business grows; firms seeking only a direct single-carrier policy should compare alternatives. Issuers vary by product and state. [4](https://www.corgi.insure/disclaimers "Disclaimers & Licensing") [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [6](https://www.prnewswire.com/news-releases/corgi-insurance-launches-admitted-insurance-carrier-302860246.html "Corgi Insurance Launches Admitted Insurance Carrier") [7](https://content.naic.org/sites/default/files/publication-loc-zu-listing-companies-summary.pdf "NAIC Listing of Companies") [8](https://content.naic.org/insurance-topics/risk-retention-groups "Insurance Topics: Risk Retention Groups")

## 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. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](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 describes professional liability as a structure tailored to a firm’s needs, naming law, accounting and consulting practices as its audience. Corgi positions Miscellaneous E&O as a catch-all for service businesses whose professional exposure is not addressed by its technology-, real-estate- or lawyer-specific products. Corgi describes claims alleging negligence, errors or failure to perform services. Buyers should check which Corgi product fits their profession before treating Miscellaneous E&O as a broad default. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes")

### Buyer Fit and Policy Terms

Corgi says this specialty product sits outside its instant-quote flow and is typically quoted in one to fourteen days; the reviewed pages publish no limit or policy structure and do not name its carrier. Aon’s page also omits quote limits and leaves the placement insurer to the account. Corgi’s reviewed pages do not describe risk-management or claims services for this product. Request the form, retroactive date, limit and claims contact from either path. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes")

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

- Ask Corgi whether your profession belongs in Miscellaneous E&O or a specialized product and who issues it. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes")
- Ask Aon for the proposed form, limits and expected placement steps for your profession. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes")

## Offering Details

| Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | Corgi Miscellaneous E&O |
| --- | --- | --- |
| 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..) | Corgi lists Miscellaneous E&O as a specialty coverage quoted with a 1-14 day turnaround, separate from its instant-quote Tech & AI Liability product and from its Real Estate E&O and Lawyer E&O products, which target specific professions. [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: Homepage and startup-insurance page policy-card labeling as of 2026-09-23. No dedicated product page was found; direct URL guesses (/miscellaneous-errors-and-omissions, /misc-eo) returned 404s..) |
| 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..) | No page names the carrier that issues Miscellaneous E&O coverage. Corgi's general disclosures say coverage may be underwritten by affiliated carriers, including Technology Risk Retention Group, or by third-party partner carriers depending on product, jurisdiction, and risk profile, without identifying which applies to this line. [4](https://www.corgi.insure/disclaimers "Disclaimers & Licensing") (Evidence: Not publicly disclosed; scope: Disclaimers page general underwriting disclosure, checked for a line-specific statement and finding none as of 2026-09-23..) |
| 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..) | Corgi targets Miscellaneous E&O at service-based businesses generally, positioned as a catch-all for professional-liability exposure not covered by its technology-, real-estate-, or legal-specific E&O products. [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: Catalog description; no industry, size, or state restrictions are published for this line..) |
| 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..) | Corgi describes Miscellaneous E&O as broad professional liability coverage for service-based businesses facing claims of negligence, errors, or failure to perform professional services, distinct from its named Tech E&O, Real Estate E&O, and Lawyer E&O products. [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: One-sentence catalog description; no policy form, insuring agreement, exclusion, or claims-made/occurrence trigger is published for this line..) |
| 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..) | No limit, retention, or illustrative policy structure is published for Miscellaneous E&O, unlike Corgi's Tech E&O and Umbrella pages, which show example limits. [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Not publicly disclosed; scope: Reviewed pages as of 2026-09-23; limits would appear on an actual quote..) |
| 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..) | The reviewed pages do not describe risk-management or claims-handling services specific to Miscellaneous E&O policyholders. [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Not found in reviewed sources; scope: Homepage and startup-insurance page as read on 2026-09-23; general claims-handling disclosures on the disclaimers page are not specific to this line..) |
| How to Apply | Confirm in your quote. | Miscellaneous E&O sits outside Corgi's instant-quote flow; the site groups it with policies quoted in 1-14 days rather than through the self-serve online application used for its core coverages. [5](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: Homepage and startup-insurance page policy-card labeling..) |
