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 HUB International?
HUB suits technology businesses seeking a specialist broker—its practice says it insures more than 5,000 technology companies; qualifying small accounts can use Insureon online, while mid-market buyers need an advisor. 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

Aon vs HUB International: D&O Insurance: documented features by provider
| Criteria | Aon Directors and Officers Liability brokerage and risk-advisory offering | HUB International Directors and Officers Insurance Brokerage |
|---|---|---|
| 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. | HUB brokers D&O liability coverage for private, nonprofit and public-company clients as part of its ProEx Professional & Executive Risk practice, rather than underwriting the policy itself. 7,8Company-reported. D&O product page and ProEx coverage list, read 2026-09-23. Neither page names an issuing insurer. |
| 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. | The D&O product page and the ProEx coverage list do not name an issuing insurer for D&O policies; HUB says ProEx places over $2 billion in premium with insurers it calls top-rated carriers, without naming them. 7,8Not found in reviewed sources. Checked both pages on 2026-09-23; the carrier for a specific D&O placement depends on the quote. |
| 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. | HUB markets D&O brokerage to three segments: private companies with customer and supplier relationships, nonprofits with advisory boards or committees, and public companies with shareholders. 7Company-reported. D&O product page target-market description; not an underwriting appetite statement. |
| 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. | HUB describes D&O coverage it arranges as addressing three areas: personal asset protection for monetary judgments and settlements from an alleged breach of duty, loyalty or care; defense in civil, criminal, judicial, administrative, regulatory or arbitration proceedings; and workplace and employment protection for breach-of-fiduciary-duty and employment-related suits. 7Company-reported. Product-page marketing description; the issued policy's insuring agreements, conditions and exclusions control an actual claim. HUB says D&O claims it sees can come from regulators, donors, clients or customers, suppliers, competitors, employees, shareholders and creditors. 7Company-reported. Product-page list of potential claim sources; not a guarantee of coverage for any specific claimant. |
| 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. | Published D&O policy limits or retentions were not found on the reviewed pages. 7,8Not publicly disclosed. Checked the D&O product page and ProEx page on 2026-09-23; limits are set on the quote and declarations. |
| 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. | HUB says its ProEx practice, which lists D&O among its Executive Liability coverages, provides analytics, litigation support and risk-management services to clients of all sizes, led by a named ProEx practice leader. 8Company-reported. ProEx page team and services description; not specific to a single D&O engagement. |
| How to Apply | Confirm in your quote. | HUB directs D&O prospects to "Connect With a Broker" rather than an online quote or bind flow. 7Company-reported. D&O product page call to action. |
| Claims Support | Confirm in your quote. | HUB describes a Claims & Legal Risks Group, staffed by attorneys who specialize in ProEx coverages including D&O, that provides management-liability claims support from pre-claim policy-wording review through claim recovery. 8Company-reported. ProEx page claims and legal support section. |
