## 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")

## Key Differences in Surety Bonds

### Digital transactional support and adviser placement

CNA says its bONdLINE platform supports underwriting, issuance and reporting for transactional bonds and serves a broad size range through agents and brokers. Marsh McLennan Agency describes arranging contract surety and commercial license-and-permit bonds with customized adviser support. If you have a clearly specified transactional obligation, ask whether CNA’s platform can issue it; for a project or commercial program, ask the MMA adviser which surety market and underwriting path would apply. [4](https://www.cna.com/products/cna-surety "CNA Surety - Surety and Fidelity Bonds | CNA Insurance") [7](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA")

### Matching bond type and business scale

MMA’s product page describes service to organizations of varying sizes, including contract surety and commercial license-and-permit programs. CNA says it serves individuals and small businesses through Fortune 1000 companies, with coverage across the United States, Canada and Puerto Rico. The records therefore document breadth on both sides but different details about delivery. Provide each contact the bond form, obligee, jurisdiction and required amount so the proposed route can be checked against the actual obligation.
