## 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 Chubb and CNA Professional Liability (E&O) Insurance?

### Professional-Service Classes

Chubb says Pro ERM is available to non-licensed professional-services firms and lists examples such as consultants, event planners, marketing and PR firms, printers, and staffing firms. CNA’s MPL target list includes consultants, staffing firms, advertising agencies, and event planners, while noting that the list is not a complete eligibility rule. A buyer in one of these fields can compare how each company describes its target class, then verify acceptance for the actual services. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")

### E&O Product Grouping

Chubb describes Pro ERM as a single policy combining professional liability, media, and cyber exposures. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") CNA’s Epack 3 brochure describes a modular combination of technology and professional liability with cyber and media. [9](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") CNA’s current cyber page separately describes EPS Plus as E&O with cyber for professional-services firms. [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") The published structures differ in how they group these lines; neither description supplies the terms of a buyer’s issued form.

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

- Ask Chubb whether the Pro ERM target class and service definition fit your operations. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Ask CNA whether your work fits its MPL target list or another E&O route. [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")
