# Aon vs Liberty Mutual: How Do They Compare for Crime Insurance?

Aon identifies professional-service firms for its crime practice, while Liberty Mutual places crime inside ProShield for private and nonprofit organizations.

## Research Scope and Use

Use this comparison to evaluate Aon and Liberty Mutual for Crime Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Aon names law, accounting and consulting firms as its Professional Services Practice audience. Liberty Mutual describes employee dishonesty, embezzlement, safe burglary and computer fraud inside ProShield, a package for private and nonprofit organizations. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")

## 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](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## 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](https://www.libertymutualgroup.com/about-lm/investor-relations/our-company/company-profile "Company Profile") [5](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions")

[Liberty Mutual profile](https://spot.insure/insurance-providers/liberty-mutual)

## 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

### 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](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")

### 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](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")

## 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](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")
- Ask Aon for the proposed policy wording and carrier; ask both providers for crime-specific limits, retentions and eligibility conditions. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")
