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 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. 4,5,6
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. 9,10,11,12,13
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 3
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 3
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 3
