## Summary

AIG describes a crime product for commercial and governmental entities. Aon lists Crime within its global practice for law, accounting, and consulting firms. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/crime-and-financial-institution-bonds "Crime and Fidelity Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

## What Is AIG?

AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. [1](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business")

[AIG profile](https://spot.insure/insurance-providers/aig)

## 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.

## What Is Crime Insurance?

Crime insurance can help reimburse specified business losses from theft and fraud, including employee theft and forgery. Compare those protections separately and ask whether a payment sent after an impersonation scam is covered. [7](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [8](https://www.travelers.com/business-insurance/professional-liability-insurance/apps-forms/crime-non-financial-institutions "Crime Non-Financial Applications and Forms") [9](https://asset.trvstatic.com/download/assets/cri-3001.pdf/98f30f1063c911eeb2f1deb19c93b21f "Crime Terms and Conditions") [10](https://www.chubb.com/us-en/business-insurance/social-engineering-fraud-coverage-for-crime-insurance.html "Social Engineering Fraud Insurance") [11](https://asset.trvstatic.com/download/assets/cri-1100w-ind.pdf/9aa2577663c911ee91291279531924d3 "Commercial Crime Coverage Application")

## Key Differences in Crime Insurance

### AIG markets crime insurance; Aon advises and arranges crime coverage for professional-services firms.

AIG says its crime insurance can cover losses of money, securities, and other assets due to dishonesty, theft, or fraud, including computer fraud. Aon identifies Crime as a line its Professional Services Practice helps arrange or advise on for law, accounting, and consulting firms, but its cited practice page does not describe covered acts or policy terms. Professional firms should ask Aon for a specific form and carrier before treating the practice listing as defined coverage. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/crime-and-financial-institution-bonds "Crime and Fidelity Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

### AIG describes a crime product for commercial and governmental entities. Aon lists Crime within its global practice for law, accounting, and consulting firms.

## What to Confirm in Crime Insurance Quotes

- AIG identifies a dedicated underwriting team and experienced claims professionals for Crime and Fidelity. Aon describes risk-management and human-capital advisory using industry knowledge, data, and tools, rather than a crime-specific claims service. The services serve different purposes: AIG’s page identifies product-side claims personnel, while Aon’s page describes broader advice. Ask who will handle placement and claims, and confirm limits, covered property, and dishonest-act triggers in writing. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/crime-and-financial-institution-bonds "Crime and Fidelity Insurance")
- Ask AIG which claim contacts and policy conditions apply to the quoted crime product. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

## Offering Details

| Criteria | AIG Crime Insurance | Aon Crime brokerage and risk-advisory offering |
| --- | --- | --- |
| Role in This Line | AIG markets crime insurance as a risk-bearing insurance product for commercial and governmental entities, separate from its financial-institution bond offering. The policy issuer is not named for a particular buyer. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/crime-and-financial-institution-bonds "Crime and Fidelity Insurance") (Evidence: Company-reported; scope: Role in this product is limited to the description on the linked AIG source..) | Aon presents Crime as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) |
| Issuing Insurer | Confirm in your quote. | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement..) |
| Who It’s For | AIG says its crime insurance is available for commercial and governmental entities. Financial-institution bonds are described separately for banks, non-bank lenders, asset managers and insurance companies. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/crime-and-financial-institution-bonds "Crime and Fidelity Insurance") (Evidence: Company-reported; scope: Audience is the segment AIG names on the linked source; this is not an underwriting decision, quote or guarantee of availability..) | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) |
| Coverage Features | AIG describes potential crime coverage for loss of money, securities and other assets from dishonesty, theft or fraud, including computer fraud. AIG links a CrimeGuard Choice sample policy; actual terms and state availability vary. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/crime-and-financial-institution-bonds "Crime and Fidelity Insurance") (Evidence: Company-reported; scope: AIG’s public product description is not the policy. Actual entitlement depends on the applicable issued form, endorsements and declarations..) | Aon lists Crime as a coverage area within its professional-services practice. The page does not describe covered dishonest acts, insured property, policy conditions or bond forms. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage..) |
| Limits and Retentions | The reviewed page and linked product overview do not state a standard buyer-specific limit, retention or deductible. Confirm those in the quote and issued policy. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/crime-and-financial-institution-bonds "Crime and Fidelity Insurance") (Evidence: Not publicly disclosed; scope: This statement reports only what the linked public source discloses and does not substitute for a quote or issued policy..) | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) |
| Risk Services | AIG identifies a dedicated underwriting team and experienced claims professionals for its Crime and Fidelity business. The page does not promise claim outcomes or specify account-level service terms. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/crime-and-financial-institution-bonds "Crime and Fidelity Insurance") (Evidence: Company-reported; scope: The linked page describes company-reported support; specific account services and third-party arrangements must be confirmed..) | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) |

## AIG Reviews

Review Score: 4.4 / 10 from 2 rated sources, equally weighted.

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.

- NerdWallet: NerdWallet editorial rating 2.5 (stars). NerdWallet’s editorial business-insurance comparison; the AIG entry concerns commercial liability and property insurance, not a quantified policyholder-review sample. The page’s complaint statement and 2.5-star editorial rating are source-specific and must not be recast as a consumer average. Checked 2026-09-29.

- Trustpilot: Trustpilot TrustScore 1.9 (out of 5); 252 reviews.

## Aon Reviews

Review Score: 6.1 / 10 from 3 rated sources, equally weighted.

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.

- J.D. Power: Aon study score 822 (out of 1000). Historical 2017 large-commercial-broker study; U.S. and Canada commercial insurance decision-makers at large organizations. J.D.
