What Are the Key Differences Between Coalition and Marsh Tech E&O Insurance?

Tech E&O Tied to Cyber vs a Custom-Built Program

Coalition designs Tech E&O that you can only buy together with its Active Cyber Insurance, sold through appointed brokers, for any business that sells a technology product or service for a fee. Marsh treats technology E&O as a financial and professional liability specialty and says off-the-shelf forms were not built for the scale of modern data centers, so it builds programs combining Tech E&O with property, casualty and other lines. Choose Coalition if you are a typical tech firm that also needs cyber; choose Marsh if you run a data center or need a program too large or unusual for a standard form. [4] [8] [7]

One Claims Team and Monitoring at Coalition

Coalition includes its Control platform, the same one used on its cyber policies, and handles Tech E&O and cyber claims with one in-house team, so a claim touching both lines goes to one place. Marsh's pages describe no monitoring platform attached to Tech E&O placements. [3] [4] [8]

What Should You Confirm in Coalition and Marsh Tech E&O Insurance Quotes?

  • Ask Marsh whether your placement is a standalone professional-liability form or part of a data-center program with property and casualty. [7]
  • Budget for Active Cyber if you choose Coalition; it will not sell Tech E&O alone. [4]
  • Ask both which insurer issues the policy. [5] [8]
  • If you operate a data center, ask Marsh which standard-form gaps its program closes. [7]

Areas of coverage

Marsh

  • role: Marsh treats technology errors and omissions (tech E&O) as one of its financial and professional liability specialties, with dedicated attention to the technology industry, and separately names it as a building block within its data-center insurance programs. Marsh professional liability page and data-center insurance page.company-reportedSource ↗Source ↗

  • coverage: Marsh says off-the-shelf technology E&O policies were not built for the scale and concentration of modern data centers and can leave gaps. It designs data center programs that combine technology E&O with property, casualty and other lines. Data center insurance page, Closing the gaps in conventional coverage section; describes a gap in standard tech E&O for one customer segment (data centers), not the general product.company-reportedSource ↗
  • insurer: The reviewed pages do not name a specific technology E&O insurer. Marsh professional liability and data-center insurance pages as read on 2026-09-23.not-disclosedSource ↗Source ↗

Coalition sells Tech E&O only together with its Active Cyber policy, with one in-house claims team and its Control platform covering both; Marsh brokers Tech E&O as a professional-liability specialty and builds custom programs for large data centers, which it says off-the-shelf forms leave exposed.
