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

Industry Scope and Program Classes

Marsh names banking, insurance and asset management, accounting, law, architecture and engineering, media, technology, healthcare and biotechnology among its professional-liability sectors. Counterpart lists separate programs for miscellaneous professionals, A&E/contractors, allied healthcare and lawyers. The lists help a buyer identify the relevant placement conversation, but do not guarantee that a particular firm or service is accepted. [6] [3] [2] [5] [9]

Coverage Description and Wording

Marsh describes professional-liability coverage for alleged errors, omissions or negligence in services and notes that many policies also address privacy violations or computer-security breaches. Counterpart’s reviewed pages describe professional-service allegations and selected limit examples. Those summaries do not establish that cyber-related loss is included in a specific Marsh or Counterpart E&O form; compare the actual insuring agreement and exclusions. [6] [5] [9]

What Should You Confirm in Counterpart and Marsh Professional Liability (E&O) Insurance Quotes?

  • Marsh: ask whether privacy or computer-security events are within the proposed E&O wording or another policy. Counterpart: request the applicable profession form, cyber-related exclusions and any separately quoted coverage. [6] [5] [9]
