## 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. [9](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [10](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [11](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [12](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 Markel Insurance Professional Liability (E&O) Insurance?

### Professional-Service Audience

CNA’s MPL target list names non-licensed consultants, staffing firms, advertising agencies, and event planners; CNA says the list is not a complete eligibility rule. Markel describes its miscellaneous E&O for targeted ProBiz industries and businesses up to $5 million in revenue. The published descriptions use different audience detail: CNA names professional classes, while Markel states a business-size ceiling and targeted industries. Ask how the actual service and revenue fit each submission. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") [8](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

### E&O Product Grouping

CNA describes Epack 3 as a modular combination of technology and professional liability with cyber and media, and EPS Plus as E&O with cyber for professional-services firms. Markel’s product page describes miscellaneous E&O separately from management-liability products. The pages therefore present a multi-line policy route at CNA and distinct E&O and management-liability product categories at Markel; they do not establish which limits or endorsements a quote will include. [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") [8](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

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

- Ask Markel whether your industry and revenue fit its ProBiz E&O description. [8](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")
- Ask CNA which MPL class and package route match the same services. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")
