Marsh says it employs attorneys, economists and actuaries alongside coverage specialists to assess a client's professional liability exposure from multiple angles, given the complexity of these risks. [4](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") (Evidence: Company-reported; scope: Marsh professional liability page..)

Corgi's Miscellaneous E&O listing describes no comparable advisory or risk-assessment service; the reviewed pages present it as a self-contained product card. [1](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance")

### Named Industry Specialties Versus a General Catch-All

Marsh names industries its professional liability experts serve, including banking and broker/dealers, insurance companies and asset managers, venture capital, accountants, attorneys, architects and engineers, media and entertainment, technology, and healthcare and biotechnology. [4](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") Corgi instead markets Miscellaneous E&O broadly to service-based businesses, separated from its own named Tech E&O, Real Estate E&O and Lawyer E&O products rather than broken out by specialized industry. [1](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance")

### What the Base Policy Can Include

Marsh says professional liability coverage protects against liability and defense costs from an error, omission or negligence claim, and that many policies also cover privacy violations and computer security breaches. [4](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") Corgi describes Miscellaneous E&O as covering negligence, errors, or failure to perform professional services, without addressing privacy or computer-security exposure in the reviewed pages.

## What Should You Confirm in Corgi and Marsh Professional Liability (E&O) Insurance Quotes?

- Ask Marsh which specialists (attorney, economist, actuary) actually reviewed your exposure, and what that review changed about the placement. [4](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- Ask Corgi whether Miscellaneous E&O includes any privacy or computer-security coverage, since the reviewed pages don't address it either way. [1](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance")
- Get the issuing insurer from both; neither reviewed page names one for this line. [4](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [3](https://www.corgi.insure/disclaimers "Disclaimers & Licensing")
- Request published limit and retention figures from both, since neither shows them.
