## 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.

## What Is Travelers Insurance?

Travelers suits technology companies that want CyberRisk Tech and can work through an independent agent; buyers seeking a direct online technology quote should compare digital providers. Many small accounts can be quoted in agent platforms, while specialty risks need underwriting.

## What Is Umbrella and Excess Liability Insurance?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. [8](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [9](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [10](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [11](https://www.coverdash.com/coverage "Coverage Hub") [12](https://kinro.com/products "Products")

## Key Differences in Umbrella and Excess Liability Insurance

### Brokered Placement and Carrier Product Paths

Aon describes umbrella and excess brokerage within its construction risk-advisory practice. Travelers says it underwrites commercial umbrella and excess and offers A/B Umbrella, excess liability, and Northfield excess-and-surplus coverage for harder-to-place risks. The difference is an adviser-led market placement versus named carrier product paths; buyers should identify which Travelers option matches the classification. [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.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance")

### Published Umbrella Limits

Travelers says umbrella typically starts at $1 million in $1 million steps and unsupported policies can reach $25 million; it does not publish maximums for excess or Northfield placements. Aon publishes no standard layer size. Compare the project limit with the specific Travelers path and the structure Aon proposes for its markets. [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.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance")

### Relationship to Primary Insurers

Travelers says umbrella is usually purchased from the insurer holding the primary coverage and may require maintaining certain primary limits with Travelers. Aon describes global market access but does not specify account-level underlying requirements. A construction buyer with several primary carriers should confirm how each proposal attaches across the schedule. [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.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance")

## What to Confirm in Umbrella and Excess Liability Insurance Quotes

- Ask Travelers which product path fits the risk and which primary limits must be held with Travelers. [7](https://www.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance")
- Ask Aon which markets can meet the limit and how the quote attaches to scheduled policies. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management")

## Offering Details

| Criteria | Aon Umbrella and Excess Liability brokerage and risk-advisory offering | Travelers Commercial Umbrella and Excess Liability Insurance |
| --- | --- | --- |
| Role in This Line | Aon says its global construction practice designs and places risk solutions and uses broking experience and a global network across construction insurance lines. For umbrella and excess liability, this is evidence of Aon’s brokered market offering; the page does not identify the insurer for a buyer’s placement. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Company-reported; scope: Aon’s global construction and infrastructure practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) | Travelers underwrites commercial umbrella and excess liability coverage as a supplemental policy layered on top of a buyer's existing general liability, auto liability and employer's liability policies, sold through three product options rather than one single form. [7](https://www.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance") (Evidence: Company-reported; scope: Commercial-umbrella product page, as read on 2026-09-23..) |
| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement..) | The reviewed commercial-umbrella page does not name the specific underwriting entity for A/B umbrella, excess liability or the Northfield excess-and-surplus-lines option. [7](https://www.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance") (Evidence: Not publicly disclosed; scope: Commercial-umbrella page as read on 2026-09-23..) |
| Who It’s For | Aon describes 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. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Company-reported; scope: Audience described for Aon’s global construction and infrastructure practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) | Travelers says commercial umbrella and excess coverage is available across all industries, and separately markets its A/B Umbrella product to small businesses as part of its small-business insurance solutions. [7](https://www.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance") (Evidence: Company-reported; scope: Commercial-umbrella page, including its small-business FAQ answer..) |
| Coverage Features | Aon lists Umbrella and Excess Liability as separate coverage areas within construction liability. The page does not specify an attachment point, underlying policy, limits or terms for a particular placement. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage..) | Travelers describes three coverage paths: A/B umbrella, excess liability, and Northfield excess-and-surplus-lines coverage for hard-to-place risks such as businesses with multiple prior claims, limited loss history or an unusual classification. [7](https://www.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance") (Evidence: Company-reported; scope: Commercial-umbrella page's solutions list and Northfield FAQ answer..)<br><br>Travelers says the policy increases limits above standard primary policies, can replace exhausted primary limits, and can offer broader coverage than the underlying policies for certain losses, but that it does not cover all legal risk, such as some instances of uninsured-motorist exposure. [7](https://www.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance") (Evidence: Company-reported; scope: Umbrella benefits section and FAQ; specific exclusions depend on the policy as issued..) |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) | Travelers says umbrella coverage typically starts at $1 million and increases in $1 million increments, and that it can write unsupported (monoline) policies with limits up to $25 million for small, midsized and large organizations. It does not publish a maximum limit for excess liability or Northfield placements. [7](https://www.travelers.com/business-insurance/commercial-umbrella "Commercial Umbrella and Excess Liability Insurance") (Evidence: Company-reported; scope: Commercial-umbrella cost section and benefits list..) |
| Risk Services | Aon describes project risk-advisory services to understand project-specific risks and develop risk-transfer, management or mitigation strategies. It also describes a global construction team and market access. These are company-reported brokerage and advisory services, not coverage benefits. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) | Confirm in your quote. |
| How to Apply | Confirm in your quote. | Travelers says an umbrella policy is usually purchased from the same insurer holding a buyer's primary coverage, which may require maintaining certain primary liability limits with Travelers first, and directs buyers to a Travelers independent agent to get started.
