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

Bundled Policy or Product by Profession

Chubb combines E&O, media and cyber in Pro ERM for non-licensed professional-services firms. [1] The Hartford sells separate E&O products for architects and engineers, healthcare professionals and technology companies, plus miscellaneous E&O and an endorsement option. [6] Choose a product designed for your profession and compare whether a separate cyber policy is needed.

Claims-Made or Occurrence

The Hartford says many E&O policies are claims-made, with a retroactive date and a 30-to-60-day reporting period that can be extended for a cost; some are occurrence policies. [6] Chubb's reviewed page does not state Pro ERM's form. [1] The form determines which policy period responds to a claim.
