# Founder Shield vs USI Insurance Services Professional Liability (E&O) Insurance

USI names CNA as the underwriter behind its AICPA program for CPAs; Founder Shield commits only to a carrier rating standard, not a named insurer.

## Research Scope and Use

Use this comparison to evaluate Founder Shield and USI Insurance Services 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

USI says the AICPA Professional Liability Program it runs for CPA firms is underwritten by CNA, while Founder Shield's E&O page names no specific insurer and instead commits to carriers rated A- or better by AM Best. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") [3](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?")

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

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [14](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [15](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [16](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [17](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

### A Named Insurer Versus a Rating Standard

USI names the specific underwriter behind the professional liability program it runs for CPA firms:

USI's own page states that the AICPA Professional Liability Program is "underwritten by CNA," naming the carrier for that specific program. USI's general Business Services E&O placements do not name an insurer. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Direct quote from the AICPA program page; CNA underwrites only this named program, not USI's other professional-liability placements..)

Founder Shield does not name an insurer for its E&O line; it instead commits to placing policies only with carriers rated A- or better by AM Best, chosen for the client's industry. [3](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?")

### Profession-Specific Program Versus Broader Client List

USI markets its named program specifically to sole practitioners and regional CPA firms, and has been the endorsed AICPA Program provider since 1994. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") Founder Shield instead names a wider range of client types for its E&O line: venture capital firms, consultants, media and advertising agencies, SaaS marketplaces, and software developers who perform services for others. [6](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance")

### Services Bundled With Coverage

USI says CPA firms enrolled in its program get supportive claims handling and exclusive access to risk-management resources, including engagement-letter templates, in addition to the coverage itself. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") Founder Shield's E&O page does not describe a comparable risk-management service; it lists coverage for defense costs, regulatory-proceeding defense, lost earnings and employee or contractor error claims. [6](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance")

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

- If your business is not a CPA firm, ask USI whether its general Business Services practice, rather than the named AICPA program, would place your E&O. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
- Ask Founder Shield to name its A- or better AM Best-rated carrier for your placement, since its page states a rating floor rather than a carrier. [3](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?")
- Ask USI for the specific limit, retention and premium for your firm, since the AICPA program page does not publish figures. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
- Neither Founder Shield's page publishes limit figures for E&O; request specific amounts directly. [6](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance")
