[4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") ## What Is Alliance Risk? Alliance Risk suits tech startups from pre-seed through IPO that want a broker to review their tech E&O policy for free and shop specialist insurers; if you want to buy online in minutes, use a digital insurer. Quotes take 24 hours to ten business days, depending on your risk. [1](https://joinalliancerisk.com/technology-insurance/ "Technology Insurance") [2](https://joinalliancerisk.com/technology-errors-omissions-insurance-tech-eo/ "Tech E&O Insurance") [3](https://joinalliancerisk.com/get-a-quote/ "Get a Quote") [Alliance Risk profile](https://spot.insure/insurance-providers/alliance-risk) ## What Is Liberty Mutual Business Insurance? Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms. [5](https://www.libertymutualgroup.com/about-lm/investor-relations/our-company/company-profile "Company Profile") [6](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [Liberty Mutual profile](https://spot.insure/insurance-providers/liberty-mutual) ## What Is Professional Errors and Omissions (E&O) Insurance? Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [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") ## What Are the Key Differences Between Alliance Risk and Liberty Mutual Professional Liability (E&O) Insurance? ### Broker advisory and policy form Alliance Risk says it places E&O through carrier partnerships and supports buyers with industry-specific risk reviews, contract review, customized wording, and claims-made structuring that considers prior acts and retroactive dates. Liberty Mutual’s specialty-program listing identifies a Physicians & Surgeons Professional program marked “PL Only,” managed by program administrators. The offerings therefore describe different service detail and target scope: broad broker advisory for professional risks versus a named physician program. Confirm the actual insurer and form in either quote. [4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") ### Professional services and fit Alliance Risk lists consultants, accountants, architects, agents, technology consultants, healthcare providers and other professional groups as intended E&O audiences. Liberty Mutual’s listing is specifically for Physicians & Surgeons Professional liability, not a general miscellaneous E&O product. A business should not assume that a broadly described E&O placement covers its licensed or contracted services; it should compare the policy’s professional-services definition and exclusions with its actual work. [4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") ## What Should You Confirm in Alliance Risk and Liberty Mutual Professional Liability (E&O) Insurance Quotes? - Ask Alliance Risk which carrier and form are proposed, including prior-acts date, tail and exclusions tied to your services. - Ask Liberty Mutual’s program administrator whether the Physicians & Surgeons program covers your specialties, entities and contracted services. ## Alliance Risk vs Liberty Mutual Professional Liability (E&O) Compared | Criteria | Alliance Risk Professional Liability Insurance | Physicians & Surgeons Professional program | | --- | --- | --- | | Role in This Line | Alliance Risk places professional liability (errors and omissions, or E&O) coverage as a broker, saying it backs placements with risk-specific underwriting input and carrier partnerships rather than underwriting the policy itself. [4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability product page..) | Liberty Mutual lists a Physicians & Surgeons Professional program, marked “PL Only,” in its specialty-program portfolio. [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") (Evidence: Company-reported; scope: Official Liberty Mutual commercial/product page; company-reported description scoped to Physicians & Surgeons Professional program.

Not policy wording, underwriting approval, state eligibility or a coverage guarantee..) | | Coverage Features | Alliance Risk lists negligent acts or omissions, breach of contract, misrepresentation, and missed deadlines as typically covered, and says bodily injury or property damage, intentional wrongdoing or fraud, employment disputes, cyber incidents, and prior known claims are excluded and belong to other lines such as general liability, EPLI or cyber liability. [4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability product page; coverage and exclusions described in general terms, subject to the policy as issued..) | The listing identifies professional liability only; it does not establish form terms, limits, exclusions or insurer for a quote. [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") (Evidence: Company-reported; scope: Official Liberty Mutual commercial/product page; company-reported description scoped to Physicians & Surgeons Professional program. Not policy wording, underwriting approval, state eligibility or a coverage guarantee..) | | Limits and Retentions | The reviewed professional liability page gives cost ranges by firm size (for example, solo practitioners at $500-$3,000 a year up to mid-sized to large firms at $10,000-$50,000-plus) but does not publish specific coverage limits, retentions or deductible amounts for this line.

[4](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..) | Confirm in your quote. | | 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. [4](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..) | The cited product page does not establish an online application or policy-binding path; ask the listed team or your broker/agent how this product is placed. [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") (Evidence: Not found in reviewed sources; scope: Reviewed product-page scope only. This not-found disposition is not a claim that no digital route exists..) | | Claims Support | Alliance Risk says professional liability clients get access to a legal network and claims experts who understand the client's industry, providing a defense strategy if a claim arises.
