CNA vs 
Marsh: How Do They Compare for Commercial Property Insurance?
CNA Small Business Insurance: Products, Agents and Service
CNA directs small-business buyers to independent agents and describes CNA Connect as a businessowners policy for more than 600 small-business classes. Issuer and availability vary by policy and state, so confirm both in a quote. 1,2,3
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. 5,6,7,8
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. 11,12,13
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 10 4
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 9
