Marsh McLennan Agency provides business insurance and employee health and benefits, alongside retirement, wealth, and private-client services across the United States and Canada.

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. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance") ## What Are the Key Differences Between Marsh and Marsh McLennan Agency Professional Liability (E&O) Insurance? ### Coverage Detail in the Published Overviews Marsh describes professional liability for errors, omissions, or negligence and says many policies also cover privacy violations and computer-security breaches. Marsh McLennan Agency names E&O plus distinct architects-and-engineers and lawyers professional liability lines, but its overview does not spell out those extensions. That difference matters if a client allegation could involve both professional work and a privacy or security incident: ask Marsh whether the extension applies to the proposed form, and ask MMA whether the relevant policy includes it rather than assuming the line label settles the question. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") ### Industry Focus and Specialist Support Marsh lists professional-liability expertise across financial services, accounting, legal, architecture and engineering, media, technology, healthcare, and biotechnology. Its described team includes attorneys, economists, actuaries, and coverage specialists to assess exposure. MMA also names architects-and-engineers and lawyers lines and describes arranging placements for organizations, but its cited overview does not set out the same industry list or team disciplines. If you need a narrow specialty, compare the people and placement experience assigned to your account, not just the shared E&O label.
