Aon vs Newfront: How Do They Compare for Umbrella and Excess Liability Insurance?

Aon says its global construction practice designs and places risk solutions and uses broking experience and a global network across construction insurance lines.

Aon’s global construction and infrastructure practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement.

Newfront places umbrella and excess liability coverage through its Casualty practice rather than underwriting it; the practice negotiates placement structure and terms with carriers on the client's behalf. ⁸Company-reported. Casualty page Our Approach and Key Coverages sections.
