What Are the Key Differences Between Marsh and Zurich U.S. Tech E&O Insurance?

Data-Center Fit and Target Classes

Marsh describes data-center programs that combine technology E&O with property, casualty, and other lines for facilities whose scale and concentration can leave gaps in conventional forms. Zurich identifies hardware and software makers and technology service providers as target E&O classes. A data-center operator should ask Zurich whether its class includes the facility’s activities and ask Marsh how the proposed lines coordinate. [4] [10]

E&O Coverage for Data-Center Operations

Marsh says conventional technology E&O may not fit data centers’ scale and concentration, and describes integrated programs with property and casualty coverage. Zurich says its technology E&O may cover defense costs, settlements, and court fees; crisis management is a conditional enhanced endorsement. Ask both for the policy wording addressing an outage, service failure, or claim arising from concentrated data-center operations. [4] [10]

  • Ask Marsh to show how its data-center program coordinates E&O with property and casualty coverage, including each carrier and limit. [4]
