Aon vs 
Liberty Mutual: How Do They Compare for Crime 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 Liberty Mutual Business Insurance?
Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms. 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
Practice audience and package eligibility
Aon identifies law, accounting and consulting firms as the audience for its professional-services practice. Liberty Mutual scopes ProShield to private and not-for-profit organizations and includes crime alongside other management-liability protections. Buyers should determine whether their organization falls within ProShield’s stated scope and whether a package suits their needs; Aon’s named sectors indicate practice focus, not a guarantee of placement eligibility. 3 6
Crime detail inside a package
Aon lists Crime as a coverage area but does not describe its policy terms. Liberty Mutual names employee dishonesty, embezzlement, safe burglary and computer fraud, and presents ProShield as a single package intended to reduce separate endorsements. A buyer should compare the specific crime insuring agreement and any enhancements with the full package wording, including how limits are shared among management-liability sections. 3 6
What to Confirm in Crime Insurance Quotes
- Ask Liberty Mutual which ProShield crime enhancements apply, whether crime has a dedicated limit, and how the package treats other management-liability claims. 3 6
- Ask Aon for the proposed policy wording and carrier; ask both providers for crime-specific limits, retentions and eligibility conditions. 3 6
