Marsh vs 
Travelers Professional Liability (E&O) Insurance

What Is Marsh?
Marsh is a global insurance broker and risk advisor. In the United States it places coverage through core Marsh teams and through Marsh McLennan Agency for many middle-market buyers, including technology, cyber, property, casualty and benefits programs. 1,2,3,4
What Is Travelers Insurance?
Travelers is a U.S. property-casualty insurance group that markets business coverage, including a technology practice, through independent agents and brokers. Buyers can investigate CyberRisk Tech, a small-business technology-services policy, and other commercial lines, then confirm the issuing company and California availability on a quote. 7,8,9
What Is Professional Errors and Omissions (E&O) Insurance?
Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. 12,13,14,15
Key Differences in Professional Liability (E&O) Insurance
Underwriter Versus Broker
Travelers underwrites errors and omissions insurance directly as one of several management and professional liability products, sold as a standalone policy written for the buyer's profession. 10 11 Marsh instead brokers the coverage through its financial and professional liability practice, placing policies with insurers on a client's behalf. 5 6
Products by Profession Versus Named Verticals
Travelers lists separate E&O products by profession, from accountants to real estate professionals to financial institutions:
Travelers offers separate E&O products by profession, including accountants, design professionals, lawyers, real estate professionals, insurance professionals, life/accident/health insurance agents, managed care organizations, financial institutions and a miscellaneous professional liability option for other client-facing professionals. 10Company-reported. Product-selection list on the E&O page.
Marsh instead names enterprise verticals as the industries its specialists serve — banking, insurance companies and asset managers, venture capital, media and entertainment, and healthcare and biotechnology — rather than a per-profession product menu. 5
Distribution Channel
Travelers directs buyers to talk to an independent agent to place E&O coverage, and separately tells agents to use its management-and-professional-liability applications and forms library. 10 11 Marsh's page instead describes its own specialist team of attorneys, economists and actuaries handling the placement directly rather than routing through an independent-agent channel. 5
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Travelers which of its named profession-specific products matches your business. 10
- Ask Marsh which insurer it intends to place your policy with, since its pages don't name one. 5
- Confirm which entity within Travelers' property-casualty affiliates would issue your specific policy. 10
- Neither reviewed page publishes limits or retentions; request both in writing. 10 5
