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. 1,2,3

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. 9,10
Key Differences in Umbrella and Excess Liability Insurance
Who Writes the Layer Versus Who Stacks Extra Limits
Chubb underwrites umbrella and excess liability insurance. Harper places umbrella and excess as extra limits stacked above a client’s existing primary policies rather than re-selling those underlying policies. A Harper quote still has to name the insurer that issues the stacked layer; Chubb is describing itself as that underwriter. 4 8
How Each Describes What Sits Under the Umbrella
Harper says the umbrella follows the terms of the policies underneath it, maps which underlying policies sit under a client’s umbrella, and responds above general liability, auto liability, and a workers’ compensation claim when an injured employee separately sues. Chubb structures umbrella and excess casualty into options for large global and national companies, mid-sized companies, energy and construction, and describes lead umbrella for large accounts. Those are different kinds of detail: Harper names follow-form underlying lines; Chubb names account segments. 8 4
How You Request a Quote
Appointed brokers can reserve, quote, bind and issue Chubb umbrella through Express Umbrella, and you can also request a quote online or through an appointed agent. You request a Harper quote through an online form or by phone; Harper says a specialist reviews the underlying policies before recommending umbrella limits. Harper says each additional million typically costs a fraction of the first million but does not publish amounts; Chubb’s reviewed page does not publish pricing or attachment points either. 4 8
