Chubb vs 
Marsh Tech E&O Insurance
Marsh designs data-center programs that combine Tech E&O with property and casualty; Chubb underwrites DigiTech ERM as a combined E&O, media and cyber policy.
What Is Chubb?
Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company. 1,2,3
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. 5,6,7,8
What Is Technology Errors and Omissions (E&O) Insurance?
Technology errors and omissions (E&O) insurance addresses claims that a technology product or service caused a customer or other third party a financial loss. It doesn't extend to cyber incidents, bodily injury or professional services outside the quoted product. 11,12,13
Key Differences in Tech E&O Insurance
Program Construction Versus a Named Policy
Marsh treats technology E&O as a financial and professional liability specialty and names it as a building block inside data-center insurance programs that also combine property, casualty and other lines. Chubb underwrites DigiTech ERM as one policy combining tech E&O with media and cyber rather than assembling a multi-line data-center tower. 10 9 3
Data-Center Gaps Versus DigiTech Additions
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. Chubb says DigiTech ERM adds third-party financial injury from products or services, a broadened technology-incident definition, software copyright infringement and product-recall loss of use, with no exclusion for delays or failure to deliver. Marsh’s reviewed pages do not name a technology E&O insurer; Chubb is the DigiTech ERM underwriter. 9 3
Adjacent Industries and Access
Marsh names technology among specialized industries its professional-liability experts serve, alongside banking, insurance and asset management, media and healthcare. Chubb targets software and system developers, technology-services and consulting firms, and electronics and hardware manufacturers, and quotes DigiTech ERM through Cyber Central or Marketplace. Neither Marsh nor Chubb publishes Tech E&O limit amounts on the reviewed pages. 10 3 1
What to Confirm in Tech E&O Insurance Quotes

- Get Marsh’s proposed insurers and limits; the reviewed pages name neither. 10
