What Is Marsh?
Marsh suits technology and larger businesses seeking specialist cyber placement or broad global risk advice; small firms wanting a quick standard quote should compare its MMA route or digital agencies. 4,5,6,7
What Is Technology Errors and Omissions (E&O) Insurance?
Technology errors and omissions coverage can help pay when a customer claims your software, hosting, installation or technology advice caused financial loss. If you provide tech products or services, check each activity; cyber incidents and unrelated professional work need separate review. 10,11,12,13,14,15,16
Key Differences in Tech E&O Insurance
Marsh focuses on data-center scale and concentration
Marsh says off-the-shelf Tech E&O policies were not built for the scale and concentration of modern data centers and can leave gaps; its data-center programs combine Tech E&O with property, casualty, and other lines. Liberty Mutual describes Liberty Tech Resolution as a blended cyber and Tech E&O solution but does not address data-center scale in the reviewed claim. A data-center operator should ask Marsh which gaps its combined program addresses and ask Liberty Mutual how its form handles concentrated exposures. 8 3
The described program structures differ
Marsh treats Tech E&O as one part of a broader data-center insurance program and also identifies it as a financial and professional liability specialty. Liberty Mutual describes a cyber and Tech E&O product but does not mention property or casualty coverage in the reviewed claim. If you want to coordinate several lines for one facility, ask each provider which policies and limits are coordinated. 8 3

Marsh’s global Trustpilot profile has a poor 1.3/5 score. Treat it as a service warning to investigate with your proposed team; it does not isolate US commercial accounts.[2][4][7]
