## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## What Is Umbrella and Excess Liability Insurance?

Commercial umbrella insurance can provide additional liability limits above scheduled underlying policies for covered claims. Don't assume umbrella and excess liability are the same coverage — the labels aren't proven synonyms. [9](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide")

## Key Differences in Umbrella and Excess Liability Insurance

### Writing the Layer Versus Shopping It

Chubb underwrites umbrella and excess liability. Mylo brokers commercial umbrella by comparing quotes from multiple carriers and does not underwrite the policy. Mylo’s product page does not name the issuing insurer. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [8](https://choosemylo.com/business/product-umbrella "Commercial Umbrella")

### Published Typical Range Versus Unpublished Attachments

Mylo says most commercial umbrella policies pay between $1 million and $15 million above exhausted general liability, commercial auto or workers’ compensation, and cannot be bought without an underlying policy. Chubb does not publish attachment points or limit amounts on the reviewed casualty page, including when umbrella is bundled in the small-business Total Account Solution. [8](https://choosemylo.com/business/product-umbrella "Commercial Umbrella") [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [5](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")

### International Contracts Versus Industry Segments

Mylo says umbrella may be needed for businesses operating internationally whose primary limits overseas protection, or that signed a contract requiring umbrella, and a licensed agent reviews whether the layer makes sense. Chubb structures options for global and national companies, mid-sized companies, energy and construction, with Express Umbrella for appointed brokers. [8](https://choosemylo.com/business/product-umbrella "Commercial Umbrella") [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance")

## What to Confirm in Umbrella and Excess Liability Insurance Quotes

- Ask Chubb which segment writes the account. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance")
- Ask Mylo where the quote sits in the $1–15 million range and which primaries attach. [8](https://choosemylo.com/business/product-umbrella "Commercial Umbrella")
