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

### Product Definition and Eligible Classes

CNA describes its Miscellaneous Professional Liability for non-licensed consultants, staffing firms, advertising agencies, and event planners, while Technology E&O is directed to technology businesses. Nationwide’s overview describes E&O for claims alleging errors or omissions in professional services and says exact eligible classes depend on underwriting. A buyer with a specialized profession should ask Nationwide about class acceptance and compare it with CNA’s named MPL or technology category. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") [9](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance")

### Buying Route and Written Terms

Nationwide’s E&O page directs prospects to contact an agent or request a quote. CNA’s Epack 3 brochure describes a quote process for small risks. Ask both what information they need about your services and contracts, then compare the named insurer, professional-services definition, limits, and exclusions in the proposals.

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

- Ask Nationwide which service classes qualify and request limits, retentions, and exclusions. [9](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance")
- Ask CNA whether MPL or Technology E&O fits and whether other modules share the aggregate. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")
