What Are the Key Differences Between CNA and Markel Insurance Professional Liability (E&O) Insurance?
Professional-Service Audience
CNA’s MPL target list names non-licensed consultants, staffing firms, advertising agencies, and event planners; CNA says the list is not a complete eligibility rule. Markel describes its miscellaneous E&O for targeted ProBiz industries and businesses up to $5 million in revenue. The published descriptions use different audience detail: CNA names professional classes, while Markel states a business-size ceiling and targeted industries. Ask how the actual service and revenue fit each submission. 4 8
E&O Product Grouping
CNA describes Epack 3 as a modular combination of technology and professional liability with cyber and media, and EPS Plus as E&O with cyber for professional-services firms. Markel’s product page describes miscellaneous E&O separately from management-liability products. The pages therefore present a multi-line policy route at CNA and distinct E&O and management-liability product categories at Markel; they do not establish which limits or endorsements a quote will include. 5 8
