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

Cyber Add-On or Standalone E&O

Coalition sells MPL only as an add-on to certain Active Cyber policies through appointed brokers. [1] The Hartford sells E&O as its own product line, including Miscellaneous Professional Liability Standalone. [6] If you do not want cyber coverage, The Hartford is the standalone product to investigate.

Coverage Form

Coalition says its duty-to-defend MPL pays defense, settlements and judgments even when the business is not ultimately at fault. [1] The Hartford lists negligence, misrepresentation, inaccurate advice, personal injury and copyright infringement; many products are claims-made with a retroactive date and 30-to-60-day reporting extension, while some are occurrence policies. [6] Confirm which form and reporting terms the quote includes.

What Should You Confirm in Coalition and The Hartford Professional Liability (E&O) Insurance Quotes?

  • Ask Coalition whether MPL can be added to your Active Cyber quote and which insurer will issue it. [1] [2]
  • Ask The Hartford whether the quote is standalone MPL, an endorsement or another product and what limit underlies the $62 average. [6]
  • Confirm whether The Hartford policy is claims-made or occurrence and its reporting period. [6]
  • Compare actual premiums at matching limits and retentions. [1] [6]
