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

General Professional Services and Technology

AIG describes E&O for alleged negligence in professional services, including economic loss to third parties. CNA’s record specifically describes technology coverage within its professional-liability products, alongside its broader miscellaneous professional-liability audience. A technology firm should compare the services definition and technology-specific triggers in CNA’s form against AIG’s entity-specific wording rather than assuming the general E&O label covers software exposures equally. [1] [2]

Claims Support

AIG says in-house claims professionals and outside experts collaborate with clients and use claims data to help evaluate and mitigate loss. CNA describes claims services for its professional-liability product. Those summaries name support functions but do not promise a claim outcome. Buyers should ask who handles a disputed technology-services claim and what notice requirements apply. [1] [2]

What Should You Confirm in AIG and CNA Professional Liability (E&O) Insurance Quotes?

  • Ask AIG how the policy treats software, technology services and third-party economic loss. [1]
  • Ask CNA which professional-liability form and claims team apply to your technology services and what notice deadlines govern. [2]
