Alliance Risk suits tech startups from pre-seed through IPO that want a broker to review their tech E&O policy for free and shop specialist insurers; if you want to buy online in minutes, use a digital insurer. Quotes take 24 hours to ten business days, depending on your risk.

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.

Commercial auto suits businesses that use vehicles for work and need liability protection; damage to your own vehicles is a separate coverage choice. If employees drive personal or rented cars, check how those trips are handled.

Aon describes professional-services advisors using industry knowledge, insights, data, and tools to support risk-management and human-capital decisions. A fleet manager can ask Alliance Risk which vehicles and safety systems will be reviewed, and ask Aon how its advisory team would address the firm’s vehicle use. These are service descriptions, not promised outcomes. [4](https://joinalliancerisk.com/commercial-auto-insurance/ "Commercial Auto Insurance") [8](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") ### Coverage Components Alliance Risk lists liability, collision, comprehensive, uninsured or underinsured motorist, and medical payments or personal-injury protection, with hired and non-owned auto as an option. Aon lists Automobile Liability in its professional-services offering. If employees use personal or rented cars, ask whether the proposed forms address that exposure and what vehicle schedule the insurer requires.

[4](https://joinalliancerisk.com/commercial-auto-insurance/ "Commercial Auto Insurance") [8](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") - Who is the insurer, and are collision, comprehensive, and liability shown separately in each proposal?

Alliance Risk has no customer ratings on the review sites we checked, so there's no Review Score yet. That says nothing bad about the company; it means you'll need to ask for references.
