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. [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") ## What Are the Key Differences Between Alliance Risk and CNA Professional Liability (E&O) Insurance? ### E&O Risk Review and Policy Structure Alliance Risk describes industry-specific reviews, claims-trend analysis, client-contract review, and help structuring claims-made policies with tail and prior-acts terms. CNA describes Epack 3 as a modular combination of technology and professional liability with cyber and media, while EPS Plus combines E&O and cyber for professional-services firms. If contract review or coordinating several lines matters, compare those services with the modules and forms in CNA’s proposal. [4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") ### Eligible Professional Classes Alliance Risk names consultants, accountants, architects, marketing agencies, technology advisors, healthcare providers, and financial professionals among its target classes. CNA says its Miscellaneous Professional Liability is for non-licensed classes such as consultants, staffing firms, advertising agencies, and event planners, while its Technology E&O serves technology businesses. Ask which CNA product maps to your actual services and whether prior acts or tail terms match Alliance Risk’s proposed placement. [4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") ## What Should You Confirm in Alliance Risk and CNA Professional Liability (E&O) Insurance Quotes? - Ask Alliance Risk to show the policy’s professional-services definition, retroactive date, and tail terms. [4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") - Ask CNA whether MPL or Technology E&O applies and how any cyber coverage is structured. [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") ## Alliance Risk vs CNA Professional Liability (E&O) Insurance Compared | Criteria | Alliance Risk Professional Liability Insurance | CNA Professional and Technology Liability | | --- | --- | --- | | 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..) | CNA describes Epack 3 as combining technology and professional liability with cyber and media in a modular policy; EPS Plus combines E&O and cyber for professional-services firms.

[4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability product page; eligibility for a particular company depends on underwriting..) | CNA says its Miscellaneous Professional Liability targets non-licensed professional classes such as consultants, staffing firms, advertising agencies and event planners. [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") (Evidence: Company-reported; scope: The listed classes are a target list, not a complete or guaranteed eligibility rule..) | | 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..) | CNA markets Technology E&O for technology businesses facing professional-liability exposures and says it is intended to support contractual requirements. [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") (Evidence: Company-reported; scope: The page is a summary and does not define covered services, contract exceptions or policy triggers..) | | 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..) | CNA describes dedicated claims and risk-control support for its cyber, media, technology and professional-liability business. [8](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") (Evidence: Company-reported; scope: This portfolio-level statement does not establish a service outcome or a line-specific claims protocol..) | | 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.
