### How Each Firm Segments the Product

Marsh McLennan Agency separately describes middle-market advisor-led placement.

### What the Base Coverage Bundles

Gallagher's small-business description covers repair or replacement of stolen, lost or damaged property, including the building, equipment and fixtures, after events like fire, windstorm or a break-in. [1](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") For data centers specifically, Marsh says property coverage is typically paired with equipment breakdown, business interruption, cyber and general liability to close gaps a standalone property policy would leave open:

For data centers specifically, Marsh says property coverage is typically paired with equipment breakdown, business interruption, cyber and general liability coverage to close gaps that a conventional property policy alone would leave open.

### Property-Specific Services

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

[4](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services")
