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

Profession range and buying model

Aon names law, accounting and consulting firms for its professional services practice; Mylo compares offers across insurers and gives examples from app development to beauty services. Ask Aon about its advisory placement if your firm fits its named practice, and ask Mylo which carriers consider your specific work. [1] [5]

Claims-made and occurrence forms

Mylo explains that E&O can be claims-made or occurrence-based and that tail coverage can extend reporting after a claims-made policy ends. Aon says it tailors coverage structures but does not set out those form choices in its reviewed summary, so request each offered form and retroactive date before comparing. [1] [5]

Quote comparison and customization

Aon describes tailored professional-liability structures; Mylo says it compares quotes and recommends coverage customized to the business. Ask each which insurer, limits and reporting terms are in the proposal, since Mylo does not underwrite and Aon’s summary does not name a carrier. [1] [5]

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

  • Ask Aon to confirm the quoted policy form, retroactive date and covered allegations; its offering says professional liability as addressing professional-services firms’ liability exposure and says it tailors coverage structures to a firm’s needs. It identifies E&O as a commonly used name for professional-liability insurance; actual policy terms are not stated. [1]
  • Ask Mylo to confirm the quoted policy form, retroactive date and covered allegations; its offering says professional liability insurance by comparing quotes from multiple business insurance companies rather than underwriting the policy itself. [5]
