What Are the Key Differences Between Marsh McLennan Agency and Zurich U.S. Professional Liability (E&O) Insurance?

Program Structure and Named Professional Lines

Zurich describes Pro Plus as a modular suite that brings coverages together in one policy and says admitted E&O is available in most states. Marsh McLennan Agency instead identifies E&O alongside separate architects-and-engineers and lawyers professional lines. If you want to place E&O with other coverages, ask Zurich which modules would appear together; if your work is in a named profession, ask MMA which specialist line applies. Neither overview establishes the endorsements or limits in an individual quote. [3] [6]

Documented Claim Scope and Service

Zurich describes E&O claims involving negligence, mistakes, or failure to deliver promised services, including defense costs, court fees, settlements, and judgments. It also identifies claims specialists who review claims under policy terms with legal counsel coordination. MMA’s overview names its professional lines but gives no comparable claims-handling steps. For a buyer, that means Zurich’s published material is more specific about its E&O claim process; ask MMA who handles a claim and what legal coordination is included before weighing service. [3] [6]
