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

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

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

### Specialist Industry Bench

Marsh identifies specialist experience across financial services, venture capital, legal and accounting practices, engineering, media, technology, and healthcare. It says attorneys, economists, and actuaries work alongside coverage specialists to assess professional-liability exposure. Insureon describes E&O for service businesses, with carrier appetite determined during its online application. For a complex or regulated firm, Marsh’s named professional mix and industry list may help scope a broker discussion; a smaller service business can use Insureon’s online request, while confirming the carrier class. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [3](https://www.insureon.com/small-business-insurance/professional-liability "Professional Liability Insurance - Get Online Quotes")

### Privacy and Computer-Security Scope

Marsh says many professional-liability policies also address privacy violations and computer-security breaches, in addition to errors, omissions, and negligence in professional services. Insureon’s overview focuses on alleged mistakes or unsatisfactory work and does not describe comparable cyber-related coverage. A firm with data exposure should ask whether any privacy or security coverage is included, limited, or placed under a separate cyber policy in each proposal. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [3](https://www.insureon.com/small-business-insurance/professional-liability "Professional Liability Insurance - Get Online Quotes")

### Carrier and Limit Details

Neither reviewed page names a specific issuing insurer or publishes limits for an individual E&O placement. Marsh’s practice places the coverage; Insureon’s quote route also leaves insurer identity to the proposal. Compare policy forms, services scope, insurer, and limits rather than assuming their broad descriptions match. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [3](https://www.insureon.com/small-business-insurance/professional-liability "Professional Liability Insurance - Get Online Quotes")

- Which professionals will assess the risk, and what insurer, limits, exclusions, and defense-cost terms are offered?
