## Alliance Risk vs Vouch Professional Liability (E&O) Insurance Summary

Vouch groups architecture, engineering and construction businesses together and identifies two potential E&O insurers through its Corix partner; Alliance Risk lists professions separately. [4](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures") [1](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")

## What Are the Key Differences Between Alliance Risk and Vouch Professional Liability (E&O) Insurance?

### Which Insurer Would Issue the Policy?

Vouch’s partner Corix names two insurers for its E&O products:

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. [4](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures") (Evidence: Company-reported; scope: Corix disclosures page..)

That disclosure applies to Corix placements; it does not establish the carrier for every Vouch quote. Alliance Risk describes carrier partnerships but does not name its insurer. Ask for the issuing company on the actual application before comparing financial strength or terms. [1](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") [4](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures")

### Architecture, Engineering and Construction Work

Vouch groups architecture, engineering and construction businesses together among its professional-services buyers. Alliance Risk lists architects and engineers but does not name construction firms. If your work spans design and construction, ask each broker to confirm the covered services and contracts. [2](https://www.vouch.us/professional-services "Insurance for Professional Services Firms") [1](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")

### How to Start the Application

Vouch’s site routes buyers to an online start flow, while Corix provides an application tied to broker appointment. Alliance Risk offers a quote request but no comparable application form. Ask which route applies to your Vouch placement and what documents you need to prepare. [3](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") [1](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")

## What Should You Confirm in Alliance Risk and Vouch Professional Liability (E&O) Insurance Quotes?

- Ask Vouch whether Corix or another partner will place your policy and which insurer will issue it. [4](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures")
- Ask Alliance Risk which carrier it proposes. [1](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")
- Request the actual limit, retention and policy form from both. [3](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") [1](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")
- If your work includes construction as well as design, confirm which contracts and services the policy covers. [2](https://www.vouch.us/professional-services "Insurance for Professional Services Firms")
