Chubb vs 
Nationwide: How Do They Compare for Professional Liability (E&O) Insurance?
Chubb’s Pro ERM combines professional, media and cyber exposures for non-licensed firms, with independent-contractor and disciplinary-defense features. Nationwide describes E&O for claims alleging professional-service errors or omissions but does not detail package structure or form features in its overview. 3,8
What Is Chubb?
Chubb fits technology firms seeking DigiTech ERM or small businesses with up to $30 million in revenue seeking a BOP; buyers wanting an instant direct purchase should compare online carriers. Agents can quote eligible small accounts, with a faster cyber route. 1,2,3
What Is Nationwide?
Nationwide’s commercial catalogue includes common small-business policies and separate specialty products. A catalogue listing does not establish eligibility or policy terms; confirm the issuing company and coverage for your state and business. 5,6,7

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. 9,10,11,12
Key Differences in Professional Liability (E&O) Insurance
Combined Coverage and Eligible Firms
Chubb underwrites Pro ERM as one policy combining professional liability, media and cyber for non-licensed professional-services firms; its examples include consultants, event planners, marketing firms, printers, staffing firms and trustees. Nationwide describes E&O for businesses providing professional services, with exact classes set by underwriting, but its overview does not identify a combined media-and-cyber form. A non-licensed firm seeking those lines together can compare Pro ERM’s package with the specific Nationwide policy parts offered. 3 8
Defense and Professional-Service Extensions
Chubb says Pro ERM covers 100% of defense costs for covered claims worldwide and adds independent-contractor coverage, client additional-insured status when required by contract, and professional disciplinary-proceeding coverage. Nationwide’s overview describes the core E&O claim type but does not specify defense-cost treatment or these extensions. Those terms can materially change the response to a client dispute, so compare the actual defense obligation and endorsements. 3 8
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Chubb whether your firm’s licensed or non-licensed status and professional technology services fit Pro ERM’s definition. 4
- Ask how Chubb’s defense-cost coverage interacts with the policy limit and whether required clients qualify for automatic additional-insured status. 3
- Ask Nationwide for the covered services, defense-cost treatment and any media or cyber coverage offered with E&O. 8
