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.

HUB International is a North American insurance brokerage that arranges business insurance, employee benefits and related risk services through local offices and specialist practices. Smaller commercial accounts may be sent to Insureon for an online quote; other programs are handled by HUB advisors, with policy terms set by the insurers they use.

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. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance") ## Key Differences in Professional Liability (E&O) Insurance ### Underwriter Versus Broker Chubb underwrites Pro ERM directly, bundling professional liability with media and cyber cover for non-licensed professional-services firms. HUB places professional liability, which it also calls errors and omissions insurance, with outside carriers rather than underwriting it, and neither of its two reviewed product pages names an issuing insurer. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [8](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") ### Coverage Structure Chubb lists specific Pro ERM add-ons over a base E&O form: personal-injury claims from professional services, coverage for independent contractors, automatic additional-insured status for clients, and coverage for professional disciplinary proceedings. HUB describes its E&O placements as typically claims-made with per-claim and aggregate limits, available with prior-acts coverage back to a retroactive date and tail coverage for an extended reporting period, and says intentional acts and employment claims are typically excluded. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [9](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") ### Who Each One Targets Chubb names a defined set of non-licensed professional-services buyers for Pro ERM, including consultants, event planners, design firms, marketing and PR firms, staffing firms, travel agents and trustees. HUB names a broader mix of licensed and unlicensed fields it serves, including accounting, architecture, creative, dental, engineering, financial, medical, media and technology businesses.

[8](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") - Ask Chubb for the Pro ERM liability limit and retention beyond its stated 100% worldwide defense-cost coverage. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") - Confirm HUB's per-claim and aggregate limit options and retroactive date terms for your specific placement. [9](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") - Ask whether your business fits Chubb's non-licensed professional-services eligibility or would need a different product for a licensed profession.

[3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Pro ERM Product Features list; subject to the policy as issued..) | HUB says professional liability/E&O policies it arranges can cover defense costs, judgments, settlements and fines from allegations of misrepresentation, breach of professional services, wrongful business practices, misleading advice and conflict of interest, plus libel, slander or lost-profit claims; intentional acts and employment claims are typically excluded. [8](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") (Evidence: Company-reported; scope: Product-page coverage description; the issued policy and its exclusions control an actual claim..)

HUB says E&O policies are typically claims-made with per-claim and aggregate limits, can be structured with prior-acts coverage back to a retroactive date, and can offer tail coverage for an extended reporting period; coverage can extend to independent contractors and temporary staff performing work for the business. [9](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") (Evidence: Company-reported; scope: E&O product-page structure description; specific limits and retroactive dates are set on the quote and declarations..) | | Limits and Retentions | Chubb says Pro ERM includes coverage for 100% of defense costs for covered claims worldwide, but the reviewed page does not publish a separate liability limit or retention.

[3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Pro ERM Product Features list..) | Not described in the reviewed sources. | | How to Apply | Agents and brokers can quote Pro ERM through Chubb's Cyber Central or Marketplace quoting platforms. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Cyber Insurance Coverage & Products page quoting section..) | HUB directs prospects to connect with a broker; the pages describe professional liability/E&O policies as customized to business size, industry, location, risk base and desired limits, without an online quote flow.
