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

### Who Each Page Names as a Fit

Pie names specific professions: architects, contractors, attorneys, engineers, consultants, marketers, counselors and real estate agents, noting some states or clients require proof of coverage. [3](https://www.pieinsurance.com/errors-and-omissions-insurance "Errors and Omissions Insurance") Marsh instead names enterprise verticals: banking and broker/dealers, insurance companies and asset managers, venture capital, accountants, attorneys, architects and engineers, media and entertainment, technology, and healthcare and biotechnology. [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

When comparing Marsh and Pie Insurance, use the stated fit categories to rule either provider in or out before spending time on an application.

### A Stated Exclusion on One Side

Pie's page states an exclusion directly:

Pie describes errors and omissions insurance, also called professional liability insurance, as covering legal fees, costs, and damages for claims that a business's advice or services caused harm, including claims of inaccurate advice, misrepresentation, negligence, or violation of good faith, but says it does not protect against criminal prosecution. [3](https://www.pieinsurance.com/errors-and-omissions-insurance "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Errors and Omissions product page as read on 2026-09-23; the issued policy controls actual insuring agreements and exclusions..)

Marsh's professional liability page describes the coverage as protecting against liability and defense costs from claims alleging an error, omission or negligence, and notes many policies also cover privacy violations and computer security breaches, but the reviewed page does not address criminal prosecution one way or the other. [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

### Reaching Each Company

Pie says it helps small businesses get coverage from its insurance carrier partners and directs buyers to contact the company to start a quote through its website. [3](https://www.pieinsurance.com/errors-and-omissions-insurance "Errors and Omissions Insurance") Marsh's page instead describes a specialist team of attorneys, economists and actuaries assessing exposure, reflecting a brokered, consultative process rather than a direct-to-website quote start. [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

- Confirm the full exclusions list with Pie beyond criminal prosecution. [3](https://www.pieinsurance.com/errors-and-omissions-insurance "Errors and Omissions Insurance")
