Chubb vs 
Hiscox Professional Liability (E&O) Insurance
Chubb bundles professional liability with media and cyber cover through brokers; Hiscox sells a standalone admitted policy directly online.
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 Hiscox?
Hiscox is a U.S. small-business insurance brand whose website is operated by Hiscox Inc., a Delaware producer that does business in California as Hiscox Insurance Agency. Eligible firms can quote general liability, professional liability, cyber and a business owner’s policy online; other advertised lines are often placed with partner insurers, so the issuing company on each quote still has to be checked. 5,6,7
What Is Professional Errors and Omissions (E&O) Insurance?
Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. 11,12,13,14
Key Differences in Professional Liability (E&O) Insurance
One Bundled Policy or a Standalone Line
Chubb's Pro ERM combines professional liability with media and cyber exposures in a single underwritten policy for non-licensed professional-services firms. Hiscox sells professional liability as a standalone line, underwritten by Hiscox Insurance Company Inc. and sold directly to small businesses through its online Hiscox NOW catalogue rather than bundled with other coverages by default. 3 10
How You Buy It
Chubb's Pro ERM is quoted by agents and brokers through Chubb's own Cyber Central or Marketplace platforms, not by the buyer directly. Hiscox lets eligible buyers quote and purchase professional liability online themselves, with licensed advisors available by phone during posted hours, and says a specialist broker can help where it doesn't sell the product online in a buyer's state. 3 8
Coverage Trigger and Claims Access
The reviewed Chubb page does not state whether Pro ERM is written on a claims-made or occurrence basis. Hiscox describes its professional liability policy explicitly as claims-made, covering a claim only if it is made and typically reported while the policy is active, and separately tells current customers its professional-liability claims line is staffed 24 hours a day, seven days a week. 9
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Chubb for the Pro ERM liability limit and retention, since the reviewed page only states 100% worldwide defense-cost coverage without a separate limit figure. 3
- Confirm whether your state is one where Hiscox sells professional liability online directly, or whether you'd need its specialist-broker path instead. 8
- Ask Hiscox for its published limit and retention options, since the reviewed pages describe the claims-made trigger but not standard figures. 8
- Ask Chubb whether Pro ERM's professional disciplinary proceedings coverage and broadened technology-services definition apply to your specific services. 3
