## Marsh vs USI Insurance Services Commercial Property Insurance Summary

Marsh McLennan Agency's technology practice pairs property with cyber, equipment breakdown and general liability for data centers. USI's technology practice instead itemizes property, business income and contingent business income as separate placement components for software and hardware companies. [2](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services") [3](https://www.usi.com/property-casualty/technology/ "Technology Insurance") [4](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting")

## What Are the Key Differences Between Marsh and USI Insurance Services Commercial Property Insurance?

### Two Technology-Focused Practices, Different Segments

Marsh's technology industry practice names data centers as its focus, pairing property with equipment breakdown, business interruption, cyber and general liability specifically for that infrastructure. [2](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services") USI's Technology practice instead names software, hardware, networking, semiconductor and communications companies from early seed stage through IPO as the segment it serves for this line.

USI's property & casualty team describes serving middle-market clients across many named industries (including construction, hospitality, real estate and manufacturing-adjacent sectors), while its Technology practice specifically serves software, hardware, networking, semiconductor and communications companies from early seed stage through IPO. [4](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting") [3](https://www.usi.com/property-casualty/technology/ "Technology Insurance") (Evidence: Company-reported; scope: Company description of client segments for each practice..)

### How Each Practice Breaks Down the Coverage

USI's Technology practice itemizes property, business income and contingent business income as three distinct placement components. [3](https://www.usi.com/property-casualty/technology/ "Technology Insurance") Marsh's technology practice instead describes a single bundle built around data-center risk, combining property with equipment breakdown, cyber and general liability rather than separating business-income coverage into its own line. [2](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services")

### Named Analytics vs. Named Alternative Risk Tools

USI says its property & casualty team uses a named USI ONE analytics process with dedicated property analysts and risk control specialists. [4](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting") Marsh McLennan Agency's (MMA) broader property page instead lists catastrophe modeling, hazard assessment and alternative risk solutions such as captives and parametric insurance. [1](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What Should You Confirm in Marsh and USI Insurance Services Commercial Property Insurance Quotes?

- Ask Marsh whether its data-center coverage bundle applies to your facility type or only to dedicated data centers. [2](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services")
- Ask USI whether contingent business income, which depends on a third party's property being damaged, is included by default or priced separately. [3](https://www.usi.com/property-casualty/technology/ "Technology Insurance")
- Get the issuing insurer from both; neither reviewed page names one for commercial property. [1](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [4](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting")
- Ask USI how its USI ONE analytics process would apply to your specific facility before assuming it changes your quote. [4](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting")
