## What Are the Key Differences Between Chubb and CNA Umbrella and Excess Liability Insurance?

### Broker Workflow and Placement Route

Chubb’s Express Umbrella platform lets appointed brokers reserve, quote, bind and issue umbrella business online. The cited Chubb material identifies distinct options for large national and global companies, mid-sized businesses, energy and construction risks. CNA’s reviewed umbrella description names form enhancements and flexible underwriting but does not identify matching size or industry segments. Buyers should ask whether their risk fits a named Chubb option and which CNA underwriting appetite applies; neither overview confirms acceptance for an individual risk. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [9](https://www.cna.com/products/umbrella "Umbrella Insurance and Excess Liability Insurance | CNA Insurance")

### Company Segments and Appetite

Chubb describes distinct umbrella or excess options for large national and global companies and mid-sized businesses, with separate approaches for energy and construction risks. CNA’s reviewed umbrella page discusses form alignment, four enhancements and underwriting but does not identify matching size or industry segments. If your business needs a segment-specific proposal, ask CNA which underwriting appetite applies and compare it with Chubb’s described categories; neither overview confirms acceptance for an individual risk. [9](https://www.cna.com/products/umbrella "Umbrella Insurance and Excess Liability Insurance | CNA Insurance") [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance")

## What Should You Confirm in Chubb and CNA Umbrella and Excess Liability Insurance Quotes?

- Ask Chubb whether the risk fits Express Umbrella, which broker appointment is required, and what form will issue. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance")
- Ask CNA how its four enhancements are triggered and whether they carry sublimits. [9](https://www.cna.com/products/umbrella "Umbrella Insurance and Excess Liability Insurance | CNA Insurance")
- Compare lead versus excess structure, limits and underlying schedule on both proposals.
