## 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 Gallagher Professional Liability (E&O) Insurance?

### Coverage and Service Classes

Gallagher describes E&O protection for allegations of negligence or injury tied to professional services, including copyright infringement, punitive damages, and claims involving past work, temporary staff, or independent contractors. CNA names non-licensed consultants, staffing firms, advertising agencies, and event planners for MPL, and separately describes Technology E&O. A business with contractors or claims tied to earlier work should ask Gallagher how those scenarios appear in the form and CNA which professional-services product fits. [11](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")

### Placement and Market Conditions

Gallagher says its small-business team places E&O through partner carriers and provides online, phone, and callback ways to request a quote. CNA’s Epack 3 brochure describes a quote process for small risks and its page identifies separate product configurations. Before submitting, ask Gallagher which partner market will assess the risk and CNA which product route accepts the described professional services. [11](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") [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 Gallagher Professional Liability (E&O) Insurance Quotes?

- Ask Gallagher which partner carrier, limit, deductible, and prior-work terms the quote uses. [11](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance")
- Ask CNA which product fits and whether E&O is bundled with cyber or media coverage. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")
