Use this comparison to evaluate CNA and Marsh for Commercial Property Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable.

## What Is Commercial Property Insurance?

Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. [11](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [12](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [13](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Perils and Data-Center Exposures

Marsh describes coverage for owned or rented assets, equipment and inventory and names flood, hurricane/windstorm, wildfire and earthquake options. For data centers, it says property is typically paired with equipment breakdown, business interruption, cyber and general liability. CNA describes placement layers rather than enumerating these perils in the cited claim. A digital-infrastructure buyer should ask how lines coordinate and which catastrophe terms apply. [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [10](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services") [4](https://www.cna.com/products/property "Commercial Property Insurance | CNA Insurance")

### Engineering and Valuation Support

CNA names sprinkler review and continuity planning. Marsh lists hazard assessment, valuations, catastrophe modeling, claims advocacy and pre- and post-loss risk control. Both identify useful risk support, while Marsh describes a broader modeling and claims menu. Ask which services are included and how business-interruption values are set. [4](https://www.cna.com/products/property "Commercial Property Insurance | CNA Insurance") [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What to Confirm in Commercial Property Insurance Quotes

- Ask Marsh to name the insurer, catastrophe terms, line coordination and valuation assumptions. [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [10](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services")
- Ask CNA which property tier and risk-control services apply. [4](https://www.cna.com/products/property "Commercial Property Insurance | CNA Insurance")
