What Are the Key Differences Between Liberty Mutual and Marsh 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. [5] [4]

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. [5] [4]

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

  • Ask Marsh which property, casualty, and Tech E&O limits are coordinated for your facility and what gaps it identified. [5]
  • Ask Liberty Mutual whether its Tech E&O form addresses data-center concentration, outages, and customer service agreements. [4]
