[3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") ## What Is Chubb?

Agents can quote eligible small accounts, with a faster cyber route.

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 Chubb and Liberty Mutual Professional Liability (E&O) Insurance? ### Combined policy and covered professions Chubb underwrites Pro ERM as one policy combining professional liability, media and cyber for non-licensed professional-services firms. It says E&O includes technology services, independent contractors, client additional-insured status when contractually required and defense for professional disciplinary proceedings. Liberty Mutual lists a Physicians & Surgeons Professional liability-only program. These stated audiences differ; a licensed professional should confirm eligibility before comparing features, while a non-licensed firm should ask whether Pro ERM’s broader bundle fits its services. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") ### Defense costs and quote detail Chubb says Pro ERM covers 100% of defense costs for covered claims worldwide but does not publish a separate liability limit or retention on the reviewed page; brokers can quote it through Cyber Central or Marketplace. Liberty Mutual’s program listing provides no limit, trigger or insurer detail. Buyers should inspect defense-cost treatment, aggregate erosion, professional-services definitions and application requirements in both quotes rather than infer equivalence from “professional liability.” [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") ## What Should You Confirm in Chubb and Liberty Mutual Professional Liability (E&O) Insurance Quotes? - Ask Chubb whether defense costs erode the limit and confirm that your professional services meet the non-licensed firm criteria. - Ask Liberty Mutual’s program administrator for issuing insurer, eligible specialties, limits and defense-cost wording. ## Chubb vs Liberty Mutual Professional Liability (E&O) Compared | Criteria | Chubb Pro ERM (Professional Enterprise Risk Management) | Physicians & Surgeons Professional program | | --- | --- | --- | | Role in This Line | Chubb underwrites professional errors and omissions coverage through Pro ERM, a single policy combining professional liability, media and cyber exposures for non-licensed professional-services firms.
