Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## What Is Lockton?

Lockton is a privately held insurance brokerage that arranges commercial risk, employee benefits and retirement programs. US pages describe a technology practice and intermediary placement with insurers, not Lockton as the policy’s insurer.

## What Are Surety Bonds?

A surety bond is a three-party agreement: a surety guarantees an obligation your business (the principal) owes to a customer or other party (the obligee) if your business defaults. It isn't insurance that pays your business for its 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")

## Key Differences in Surety Bonds

### Who Writes the Bond Versus Who Brokers It

Chubb underwrites surety bonds directly. Lockton Surety brokers surety bonds and says it has become one of the largest surety brokers in the world, representing more than 2,000 clients across industries; Lockton is the broker facilitating the bond relationship, not the surety. Lockton’s surety page does not name the surety companies it places with. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [8](https://global.lockton.com/us/en/surety "Surety")

### Published Bond Menu Versus Data-Driven Broker Services

Chubb lists Construction, Commercial, Transactional and International Surety Bonds, including performance, payment, license and permit, court and customs types, plus Surety Marketplace for transactional needs. Lockton’s reviewed surety page does not itemize those bond types; it lists data-driven services: financial statement analysis and credit rating, weighted backlog analysis, financial and rate peer comparisons and benchmarking, individual project and composite profit trend analysis, and detailed safety record review. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [8](https://global.lockton.com/us/en/surety "Surety")

### Capacity Figures Versus an Unnamed Panel

Chubb reports a $2.289 billion aggregate Treasury listing as of August 2026 and capabilities in more than 45 countries, and publishes surety-claim submission instructions. Lockton says it tailors its surety service model to each client rather than a single standard approach, without publishing a Treasury listing or named industries. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [8](https://global.lockton.com/us/en/surety "Surety")

## What to Confirm in Surety Bonds Quotes

- Ask Lockton which surety would issue the bond and which of its analytic services apply to your program. [8](https://global.lockton.com/us/en/surety "Surety")
- Ask Chubb which product line and, for small needs, whether Marketplace applies. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds")
- If you have a construction backlog, ask Lockton how weighted backlog analysis would be used. [8](https://global.lockton.com/us/en/surety "Surety")
- Confirm Chubb claim contacts if Chubb writes the instrument. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds")
