## What Are the Key Differences Between Harper and Hiscox Professional Liability (E&O) Insurance?

### Named Underwriter Versus Unnamed Carrier

Hiscox's page states which entity underwrites its admitted professional liability policies directly: [7](https://www.hiscox.com/documents/partner-agent/appetite_guide/Hiscox-NOW-Appetite-Guide.pdf "Hiscox US Agent Appetite Guide")


Hiscox's appetite guide and About Hiscox US page name Hiscox Insurance Company Inc. (NAIC 10200) as the underwriter of admitted Hiscox NOW professional-liability policies. [7](https://www.hiscox.com/documents/partner-agent/appetite_guide/Hiscox-NOW-Appetite-Guide.pdf "Hiscox US Agent Appetite Guide") [6](https://www.hiscox.com/about-hiscox-insurance "About Hiscox US Insurance") (Evidence: Company-reported; scope: Admitted small-business professional liability as described in company materials; the exact contracting entity for a particular state or channel should be confirmed on the quote..)

Harper instead places professional liability with carriers it does not name; its pages describe pricing drivers, services performed, revenue and contract size, without naming an issuing insurer. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

### Policy Trigger

Hiscox describes professional liability as a claims-made policy, meaning a claim is covered only if it is made, and typically reported, while the policy is active. [5](https://www.hiscox.com/small-business-insurance/professional-liability-insurance/pl-faq "What is Professional Liability Insurance?") Harper's pages describe coverage for errors and omissions in the work itself, negligence allegations, and legal defense costs, but do not state whether the policies it places are claims-made or occurrence. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

### Geographic Availability

Hiscox says professional liability is licensed for sale in 49 states and Washington, D.C., excluding Alaska, and that a specialist broker may help in states where it does not sell online. [4](https://www.hiscox.com/small-business-insurance/professional-liability-insurance "Professional Liability Insurance for Small Businesses") Harper's pages do not state a jurisdiction limit; they instead target consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

- Harper's professional-liability pages name pricing drivers but not a carrier; ask which insurer it places once it presents options for your business. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Neither reviewed page publishes specific limit or retention amounts; request both directly. [4](https://www.hiscox.com/small-business-insurance/professional-liability-insurance "Professional Liability Insurance for Small Businesses") [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
