It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote. ## Summary Chubb underwrites professional E&O through Pro ERM for non-licensed professional-services firms and includes automatic additional-insured status, while Alliance Risk places professional liability as a broker for a list that includes licensed professions such as architects, engineers and accountants.

Alliance Risk describes itself as an independent commercial insurance brokerage serving complex businesses, including technology startups. Its offering includes technology E&O placement and review of existing policies. [1](https://joinalliancerisk.com/about-us/ "About Us") [2](https://joinalliancerisk.com/technology-errors-omissions-insurance-tech-eo/ "Tech E&O Insurance") [Alliance Risk profile](https://spot.insure/insurance-providers/alliance-risk) ## 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.

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. [8](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [9](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [10](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [11](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 ### Who Each One Targets Chubb writes Pro ERM specifically for firms that are not licensed professionals: Chubb says Pro ERM is available to non-licensed professional-services firms of all sizes, naming examples including associations, consultants, business process administrators, event planners, interior and graphic design firms, marketing and PR firms, printers, staffing firms, travel agents and trustees. [6](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 Target Clients list..) Alliance Risk's target list runs the other way, naming accountants and tax professionals, architects and engineers, and real estate and insurance agents and brokers among the professions it places professional liability for. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") ### What Comes Built Into the Policy Chubb's page lists automatic additional-insured status for clients when required by contract and coverage for professional disciplinary proceedings as part of Pro ERM. Alliance Risk instead describes services layered around the policy, such as reviewing client contracts to limit personal exposure and structuring claims-made terms like tail coverage and retroactive dates. [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") ### How You Buy It Chubb routes Pro ERM through agents and brokers quoting on its Cyber Central or Marketplace platforms. Alliance Risk's reviewed page offers only a generic "Get a quote" request, without the specific submission checklist its own D&O, EPLI and fiduciary pages provide. [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") ## What to Confirm in Professional Liability (E&O) Insurance Quotes - Ask Chubb to confirm whether your business qualifies as "non-licensed" under Pro ERM's eligibility terms. [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") - Ask Alliance Risk which carrier will actually underwrite your professional liability policy. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") - Ask Chubb for the actual liability limit and retention on your quote, since its page publishes defense-cost terms but not a standard limit. [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") - Ask Alliance Risk what information it needs to submit your application, since its page does not list a specific checklist.

[3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability product page, Our Approach to Professional Liability and The Alliance Risk Difference sections..) | Chubb says Pro ERM policyholders get access to legal counsel with extensive professional-liability experience, in addition to the general cyber-incident-response services shared with Cyber ERM. [6](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..) | | How to Apply | The professional liability page's only application route is a generic 'Get a quote' request; it does not list the specific submission information Alliance Risk asks for on this line, unlike its D&O, EPLI and fiduciary product pages. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Not found in reviewed sources; scope: Professional liability product page as read on 2026-09-23..) | Agents and brokers can quote Pro ERM through Chubb's Cyber Central or Marketplace quoting platforms.
