## Aon vs Embroker Surety Bonds Summary

Aon: construction surety bonds and describes them as financial security intended to guarantee contractor performance and payment to specified subcontractors, laborers and material suppliers. Actual bond obligations depend on the bond form and its terms. Embroker: contractor license, bid, construction performance, payment, maintenance, utility, supply and subdivision bonds as construction bond types it can help obtain, and explains that a bond protects the obligee, not the contractor who purchased it. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.embroker.com/coverage/surety-bonds/ "Construction Bonds: Surety Bond Types & Cost")

## 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.

## What Is Embroker?

Embroker suits technology firms seeking a single application for management coverage plus eligible Tech E&O and cyber, and law firms seeking a grouped package; buyers needing only standard small-business coverage should compare direct carriers.

## What Are Surety Bonds?

A surety bond guarantees that your business meets a specific obligation to a customer, contracting party or government agency. If a contract, license or permit requires one, get its exact form and amount; a bond is not insurance for your own losses. [8](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [9](https://www.sba.gov/funding-programs/surety-bonds "Surety bonds") [10](https://www.law.cornell.edu/uscode/text/40/3131 "40 U.S. Code § 3131 — Bonds of contractors of public buildings or works") [11](https://www.chubb.com/us-en/surety.html "Surety Bonds") [12](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

## What Are the Key Differences Between Aon and Embroker Surety Bonds?

### Bond forms for the stated obligation

Aon describes its global construction practice designs and places risk solutions and uses broking experience and a global network across construction insurance lines. For construction surety, this is evidence of Aon’s brokered market offering; the page does not identify the insurer for a buyer’s placement. Embroker describes contractor license, bid, construction performance, payment, maintenance, utility, supply and subdivision bonds as construction bond types it can help obtain, and explains that a bond protects the obligee, not the contractor who purchased it. A bond protects the obligee under the named obligation, so compare the required form and conditions against the contract or license before choosing a route. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.embroker.com/coverage/surety-bonds/ "Construction Bonds: Surety Bond Types & Cost")

### Applicant profile and service model

Aon identifies its global construction and infrastructure practice as serving contractors, owners, developers, engineers, architects, designers, financiers and investors, and says it works with organizations of varied sizes and complexity. Embroker identifies surety bonds as most commonly needed in construction, required at the state, county or city level before a contractor can work on a project, but says they matter in other industries too. A contractor or business should ask whether its trade, financial profile and bond amount fit the stated market and what documentation will be needed. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.embroker.com/coverage/surety-bonds/ "Construction Bonds: Surety Bond Types & Cost")

### How the application moves

Aon describes its global construction practice designs and places risk solutions and uses broking experience and a global network across construction insurance lines. For construction surety, this is evidence of Aon’s brokered market offering; the page does not identify the insurer for a buyer’s placement. Embroker describes applicants to identify the specific bond type and bonding amount needed, then get a quote through its platform; it says most developers will also require proof of general liability, commercial property and workers' compensation insurance before hiring a bonded contractor. Confirm the submission deadline, required indemnitors and how the executed bond reaches the obligee. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.embroker.com/coverage/surety-bonds/ "Construction Bonds: Surety Bond Types & Cost")
