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.

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

### Professional Program Selection

CNA describes Miscellaneous Professional Liability for non-licensed consultants, staffing firms, advertising agencies, and event planners, with Technology E&O serving a separate technology audience. Counterpart lists distinct programs for miscellaneous professionals, architects and engineers or contractors, allied health, and lawyers. A firm with regulated work should identify its exact profession and services first, then compare the profession-specific Counterpart form with the CNA class and wording proposed for that work. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") [8](https://yourcounterpart.com/products/miscellaneous-professional "Professional & General Liability") [11](https://yourcounterpart.com/products/lawyers-professional-liability "Lawyers Professional Liability Insurance")

### Limits and Distribution

Counterpart says its professional programs support modular limits and publishes sample limits and retentions for selected professions; those examples are illustrative. CNA’s public page names target non-licensed MPL classes, including consultants and staffing firms. Ask Counterpart which profession-specific program and limit apply, and CNA which target class and quoted limit match the same services. [8](https://yourcounterpart.com/products/miscellaneous-professional "Professional & General Liability") [11](https://yourcounterpart.com/products/lawyers-professional-liability "Lawyers Professional Liability Insurance") [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")
