## 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. [12](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [13](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [14](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [15](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

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

### Industry and Risk Assessment

Marsh names banking, broker-dealers, accountants, attorneys, architects and engineers, technology, media, and healthcare among the industries its professional-liability specialists serve. It says its team includes attorneys, economists, and actuaries alongside coverage specialists to assess exposures. CNA describes MPL for non-licensed classes such as consultants, staffing firms, and event planners, and Technology E&O for technology businesses. A specialized firm should compare its actual services and assessment needs against each provider’s stated audience. [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")

### Coverage and Carrier Terms

Marsh says professional-liability coverage may address liability and defense costs for alleged errors, omissions, or negligence, and that many policies also cover privacy violations or computer-security breaches. CNA describes Epack 3 and EPS Plus as E&O combinations with cyber. A business with a cyber-related professional claim should compare how each proposed form coordinates those coverages and ask Marsh which insurer and policy wording are being placed. [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [5](https://www.cna.com/sites/default/files/assets/epack-3-cyber-media-technology-professional-liability-ss.pdf?ContentCache=NONE&MOD=AJPERES "Epack 3 – Cyber, Media, Technology & Professional Liability")

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

- Ask Marsh which insurer, professional-services definition, and cyber-related terms are proposed. [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- Ask CNA whether Epack 3 or EPS Plus fits and how the limit responds to cyber allegations. [5](https://www.cna.com/sites/default/files/assets/epack-3-cyber-media-technology-professional-liability-ss.pdf?ContentCache=NONE&MOD=AJPERES "Epack 3 – Cyber, Media, Technology & Professional Liability")
