## 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. [9](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [10](https://www.sba.gov/funding-programs/surety-bonds "Surety bonds") [11](https://www.law.cornell.edu/uscode/text/40/3131 "40 U.S. Code § 3131 — Bonds of contractors of public buildings or works") [12](https://www.chubb.com/us-en/surety.html "Surety Bonds") [13](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

## Key Differences in Surety Bonds

### Transactional self-service and agent-led reach

Chubb says its online Surety Marketplace handles transactional bonds, while its other products go through appointed agents and brokers. CNA likewise serves buyers through agents and brokers, and says its bONdLINE supports transactional-bond underwriting, issuance and reporting. For a smaller or infrequent obligation, the practical question is whether the required bond type can be completed through a self-service marketplace or whether an agent-mediated platform is the applicable route. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [8](https://www.cna.com/products/cna-surety "CNA Surety - Surety and Fidelity Bonds | CNA Insurance")

### Bond portfolio breadth

Chubb lists construction, commercial, transactional and international surety, including license, court, contract and customs bonds. CNA describes commercial and contract bonds across all 50 states, Canada and Puerto Rico. The wider named categories in Chubb’s reviewed record may matter for cross-border or specialized needs, while CNA’s stated geography is explicit. Confirm the obligee’s exact bond form and jurisdiction with either provider before treating a general category as available for your project. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [8](https://www.cna.com/products/cna-surety "CNA Surety - Surety and Fidelity Bonds | CNA Insurance")

## What to Confirm in Surety Bonds Quotes

- Does Chubb Surety Marketplace support the exact bond type, amount and jurisdiction required by the obligee? [4](https://www.chubb.com/us-en/surety.html "Surety Bonds")
- Can CNA bONdLINE process this obligation, and which agent handles issuance in the relevant location? [8](https://www.cna.com/products/cna-surety "CNA Surety - Surety and Fidelity Bonds | CNA Insurance")
