## Summary

[3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/global/forefront-portfolio-product-sheets/2021-09.03_Forefront_Portfolio_Crime.pdf "The ForeFront Portfolio — Crime Insurance") [8](https://www.chubb.com/us-en/business-insurance/forefront.html "The ForeFront Portfolio")

## 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 Chubb?

Chubb fits technology firms seeking DigiTech ERM or small businesses with up to $30 million in revenue seeking a BOP; buyers wanting an instant direct purchase should compare online carriers. Agents can quote eligible small accounts, with a faster cyber route.

## 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. [9](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [10](https://www.travelers.com/business-insurance/professional-liability-insurance/apps-forms/crime-non-financial-institutions "Crime Non-Financial Applications and Forms") [11](https://asset.trvstatic.com/download/assets/cri-3001.pdf/98f30f1063c911eeb2f1deb19c93b21f "Crime Terms and Conditions") [12](https://www.chubb.com/us-en/business-insurance/social-engineering-fraud-coverage-for-crime-insurance.html "Social Engineering Fraud Insurance") [13](https://asset.trvstatic.com/download/assets/cri-1100w-ind.pdf/9aa2577663c911ee91291279531924d3 "Commercial Crime Coverage Application")

## Key Differences in Crime Insurance

### Coverage and Buyer Profile

Chubb lists social-engineering fraud, employee theft including temporary workers, client property theft by an employee, and funds-transfer loss not reimbursed by a bank. Its ForeFront target is under 250 employees and under $50 million in revenue. Aon lists crime for professional-services firms without terms or thresholds; ask it for the equivalent coverage schedule and appetite. [7](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/global/forefront-portfolio-product-sheets/2021-09.03_Forefront_Portfolio_Crime.pdf "The ForeFront Portfolio — Crime Insurance") [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

### Policy Role and Issuer

Chubb underwrites crime within its ForeFront Portfolio and names ACE American Insurance Company and U.S.-based Chubb underwriting affiliates as insurers. Aon describes broker-arranged crime and does not identify the carrier for a placement. Ask Aon to name the proposed insurer and compare its policy role with Chubb’s issued form. [7](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/global/forefront-portfolio-product-sheets/2021-09.03_Forefront_Portfolio_Crime.pdf "The ForeFront Portfolio — Crime Insurance") [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

### Application Route

Chubb makes ForeFront available on Chubb Marketplace for digital quoting, binding, and issuance. Aon describes professional-services brokerage but does not publish a crime-specific application route. If an online bind path matters, compare Chubb's stated platform with Aon's submission process and confirm whether your organization meets the marketplace appetite. [7](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/global/forefront-portfolio-product-sheets/2021-09.03_Forefront_Portfolio_Crime.pdf "The ForeFront Portfolio — Crime Insurance") [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

## What to Confirm in Crime Insurance Quotes

- Does your organization meet Chubb’s employee and revenue thresholds, and how are bank-reimbursed transfers treated?
- What crime forms, carrier, and application steps will Aon use for your professional-services firm?

| Limits and Retentions | 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. [3](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..) | The reviewed product sheet illustrates claim scenarios with losses ranging from over $100,000 to over $1 million but does not publish specific policy limits, sublimits or retentions for Crime coverage.

| Risk Services | 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. [3](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..) | Confirm in your quote. |
