What Are the Key Differences Between CNA and The Hartford Professional Liability (E&O) Insurance?

Program structure for technology and professional firms

CNA describes Epack 3 combining technology and professional liability with cyber and media, while EPS Plus combines E&O and cyber for professional-services firms. The Hartford describes professional liability around mistakes in client services, including baseless allegations. For a buyer seeking E&O alongside other lines, CNA names modular structures; The Hartford’s reviewed material instead explains the kinds of allegations its professional liability can address. [1] [6]

Allegations and policy timing

The Hartford lists negligence, misrepresentation, inaccurate advice, libel or slander, copyright infringement and defense costs, and says many forms are claims-made while some are occurrence policies. CNA identifies dedicated claims and risk-control support but its reviewed claims do not specify those triggers or allegation categories. Ask each carrier to map your service-specific exposures to the actual wording, then compare retroactive dates and any extended reporting period rather than assuming the product descriptions settle them.
