What Are the Key Differences Between Aon and Liberty Mutual 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. [1] [4]

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. [1] [4]

What Should You Confirm in Aon and Liberty Mutual 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. [1] [4]
  • Ask Aon for the proposed policy wording and carrier; ask both providers for crime-specific limits, retentions and eligibility conditions. [1] [4]
