Aon vs 
USI Insurance Services: How Do They Compare for Fiduciary Liability Insurance?
What Is Aon?
Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. 1,2
What Is USI Insurance Services?
USI suits software and hardware companies from seed stage through IPO seeking consultative broker support; buyers wanting a self-serve quote should compare digital agencies. Insurer commissions are typical and contingent compensation may also apply. 4,5,6

What Is Fiduciary Liability Insurance?
Fiduciary liability can protect your company and plan fiduciaries when participants claim mishandling of an employee benefit plan. If you sponsor a retirement or health plan, check who is insured and whether both administration errors and fiduciary-breach claims are addressed. 9,10,11
Key Differences in Fiduciary Liability Insurance
Placement and plan-review support
Aon describes fiduciary liability within a global professional-services brokerage practice and says its advisors use industry knowledge, data, and tools for risk and human-capital decisions. USI says it brokers the line and reviews existing fiduciary coverage for gaps through ExecuSafe. A buyer reviewing a current management-liability program can ask USI specifically for that gap review; Aon’s published description is broader advisory support. 3 7
A named coverage discussion versus a practice listing
Aon lists fiduciary liability but does not explain which plan acts or terms its placements cover. USI describes protection against claims of employee-benefit-plan mismanagement and says it may place the coverage individually or review it in a management-liability program. Neither description names a carrier or states limits, so the quote and policy need to settle those specifics. 3 7

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.[4][6][7]

The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage. | USI lists fiduciary liability among the coverages it places for business-services clients, and separately says its ExecuSafe review looks for gaps in a client's existing fiduciary liability coverage as part of a management liability review. 7,8Company-reported. Catalogue listing plus the ExecuSafe review description; actual insuring agreements and exclusions are set by the issued policy. |

Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated. | USI's Business Services practice says it offers classification and exposure reviews, claim advocacy and risk control across its coverage lines, including fiduciary liability, and its ExecuSafe process specifically reviews existing fiduciary liability policies for coverage gaps. 7,8Company-reported.
