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 Directors and Officers Insurance?
D&O insurance can help pay covered defense costs and losses from claims against company leaders over management decisions. If your organization has a board or executives, check whether the company itself is insured and whether legal bills reduce the limit. 9,10,11
Key Differences in D&O Insurance
Named Program and Target Companies
USI describes ExecuSafe for small and midsize businesses and separately places technology D&O from seed stage through IPO. Aon discusses public and private company programs and explains Side A, B and C. Ask USI whether ExecuSafe fits your organization and compare Aon’s proposed structure by company stage and board needs. 3 7
Coverage Design and Benchmarking
USI cites a technology client example where benchmarking led to lower excess D&O limits and premium. Aon describes insurer-selection analytics and a Risk Analyzer. These methods do not promise savings; ask each broker to show the peer group, exposures and assumptions behind its limit recommendation. 3 7
What to Confirm in D&O Insurance Quotes
- Ask USI which carrier issues ExecuSafe and whether limits are shared; ask Aon for analytics assumptions and Side A/B/C wording. 3

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]

Aon vs USI Insurance Services: D&O Insurance: documented features by provider
| Criteria | Aon Directors and Officers Liability brokerage and risk-advisory offering | USI ExecuSafe Directors & Officers Liability Program |
|---|---|---|
| Role in This Line | Aon markets D&O broking and advisory services, including insurer selection and program design. It does not issue the described coverage or name the carrier for a buyer’s placement. 3Company-reported. Aon’s official global product/capability page. The statement is limited to Aon’s marketing of brokerage or advisory services, not policy issuance. | USI is a broker for D&O coverage. It says it helps clients identify D&O exposures, review any existing management liability policies for gaps, and place coverage, including through its own named endorsement package, ExecuSafe. 7Company-reported. ExecuSafe article's "How USI Can Help" section. |
| Issuing Insurer | The reviewed page does not identify the insurer or the legal producing entity for a specific placement. Ask Aon to identify both for the quoted risk. 3Not found in reviewed sources. Aon’s global product/capability page reviewed 2026-09-30; no buyer quote, binder or policy was reviewed. This does not establish that no insurer or producing entity is available. | USI does not name the insurer that underwrites ExecuSafe or other D&O placements on the pages reviewed; it describes ExecuSafe as an endorsement package it applies to policies placed with the market. 7Not publicly disclosed. ExecuSafe article and Technology/Business Services practice pages as read on 2026-09-23. |
| Who It’s For | Aon describes D&O services for public and private companies and discusses executives, directors, managers and board members. This is a target-audience description, not an underwriting eligibility schedule. 3Company-reported. Audience stated by Aon on its global capability page; this does not establish a specific applicant’s eligibility or placement availability by U.S. state. | USI targets small- and medium-sized businesses for ExecuSafe, saying many either skip D&O coverage or buy insufficient limits because their brokers do not help them identify the exposure. Its Technology practice separately places D&O for software, hardware and communications clients from seed stage through IPO. 7,5Company-reported. ExecuSafe article eligibility framing and Technology practice client description. |
| Coverage Features | Aon explains D&O policies generally through Side A individual protection when company indemnity is unavailable, Side B reimbursement when the company indemnifies a director or officer, and Side C entity coverage, with different descriptions for public and private companies. It notes exclusions can apply; an issued policy determines the actual scope. 3Company-reported. Aon’s broker-authored explanation of the insurance line. It does not establish an individual insured’s policy entitlement; the insurer’s form, endorsements and declarations control. | USI says D&O insurance is meant to protect a company's leadership from personal loss in a lawsuit, since the corporate veil does not shield directors and officers from personal liability for the business's actions and debts. It lists breach of contract, breach of duty, misrepresentation, unfair competition, misappropriation of trade secrets, securities lawsuits and creditor lawsuits as common claim types the coverage responds to. 7Company-reported. ExecuSafe article's description of D&O purpose and claim types; actual insuring agreements and exclusions are set by the issued policy. |
| Limits and Retentions | The reviewed page does not state a standard buyer-specific limit, retention or deductible for this placement. Confirm amounts, sublimits and conditions in the quote and issued policy. 3Not publicly disclosed. Aon’s global product/capability page reviewed 2026-09-30; no buyer quote or policy form was reviewed. | USI cites a 2016 Chubb survey that found 43% of private companies carry no D&O coverage, with an average private-company D&O claim cost of $450,000, but the article does not publish USI's own placed limits, retentions or premium ranges for ExecuSafe. 7Not publicly disclosed. Third-party statistic cited by USI to illustrate exposure, not USI's own placement data. |
| Risk Services | Aon says its brokerage and claims teams collaborate on coverage negotiations and describes insurer-selection analytics and a D&O Risk Analyzer. Those are broker services, not an insurer claim decision or guarantee. 3Company-reported. Company-reported brokerage and advisory services. Account-specific service terms are not stated. | USI's Technology practice cites a case study where its benchmarking analysis showed a software company was buying more D&O limit than peers with similar risk profiles, and says the resulting change saved the client more than $100,000 per year in D&O premium. 5Company-reported. Single case study on the Technology practice page; company-reported outcome, not independently verified. |
| How to Apply | Confirm in your quote. | USI directs small- and medium-sized businesses interested in ExecuSafe to email Select.Business@usi.com; its Technology and Business Services practices separately route inquiries to pcinquiries@usi.com or a local USI office. 7,5,8Company-reported.
