Key Differences in Professional Liability (E&O) Insurance
Modular programs or a marketplace quote
CNA describes Epack 3 as modular technology and professional liability with cyber and media, and EPS Plus as E&O with cyber for professional-services firms. Simply Business instead describes answering business questions online, comparing quotes and selecting a policy; its listed occupations include consultants and bookkeepers. A buyer deciding between a named CNA program and a comparison process should identify the exact profession and requested combination before comparing terms. 4 8
Professional-class examples and quote eligibility
CNA names non-licensed consultants, staffing firms, advertising agencies and event planners for its miscellaneous professional liability, while Simply Business also lists IT professionals and real-estate agents as examples. Those lists point to different starting audiences, not guaranteed acceptance: Simply Business expressly says examples do not ensure eligibility. Ask each route whether your specific services fit and what policy form a quote would use. 4 8
