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. 1,2
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. 4,5
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. 7,8,9,10,11
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.

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
- Ask AIG which claim contacts and policy conditions apply to the quoted crime product. 6
