## Research Scope and Use

Use this comparison to evaluate Cowbell and Heffernan Insurance Brokers for Fiduciary Liability Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Cowbell’s fiduciary cover is a Zurich-underwritten Select Plus module sold only through appointed wholesalers. Heffernan shops fiduciary liability for general businesses and for family offices, trusts, and similar financial clients, and does not name the issuing insurer.

## What Is Fiduciary Liability Insurance?

Fiduciary liability insurance addresses covered claims alleging breaches of duties in managing employee benefit plans. [9](https://www.dol.gov/sites/dolgov/files/ebsa/employers-and-advisers/guidance/field-assistance-bulletins/erisa-fidelity-bonding-requirements.pdf "Field Assistance Bulletin No. 2008-04: Guidance Regarding ERISA Fidelity Bonding Requirements") [10](https://www.travelers.com/business-insurance/professional-liability-insurance/fiduciary-liability "Fiduciary Liability Insurance")

## Key Differences in Fiduciary Liability Insurance

### Who Carries the Risk

Cowbell runs the quoting platform for Zurich’s Select Plus product, and Zurich underwrites the fiduciary module on admitted paper. Heffernan is a broker: it places fiduciary liability with insurers for two practices and does not issue the policy. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [3](https://www.zurichna.com/insurance/excess-and-surplus/small-business-management-liability "Small and Midsize Business Management Liability | Zurich Select Plus") [7](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [8](https://www.heffins.com/family-office/ "Family Office")

### Who the Product Is Built For

Cowbell aims the module at private companies with fewer than 250 employees and under $50 million in assets, in industries such as manufacturing and technology. Heffernan lists the line for ordinary business clients and, separately, for family offices, trust companies, trustees, advisors, private equity firms, foundations, and other financial institutions. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [7](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [8](https://www.heffins.com/family-office/ "Family Office")

### How You Reach Coverage

You cannot buy the Cowbell module as a business; appointed Zurich E&S wholesalers access it through Cowbell’s API. Heffernan’s family-office fiduciary placement goes through a named Private Client Group specialist, while its general business listing routes through a contact form. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [8](https://www.heffins.com/family-office/ "Family Office")

### What the Reviewed Pages Describe as Coverage

Cowbell defines the module as protection against claims from breaches of fiduciary duty on employee benefit plans such as a 401(k) or health plan. Heffernan’s family-office page lists fiduciary liability beside D&O, professional liability, EPL, and trustee liability, without describing insuring agreements or exclusions. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [8](https://www.heffins.com/family-office/ "Family Office")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask which Zurich entity would issue a Cowbell Select Plus fiduciary module, and which insurer Heffernan would place for your segment. [3](https://www.zurichna.com/insurance/excess-and-surplus/small-business-management-liability "Small and Midsize Business Management Liability | Zurich Select Plus") [7](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")
- Confirm whether Heffernan is quoting through its business-insurance desk or its family-office practice, since the two use different intake paths. [8](https://www.heffins.com/family-office/ "Family Office")
- Get limits and retentions in writing; neither Cowbell’s nor Heffernan’s reviewed pages publish them. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [7](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")
- Ask Heffernan what a Risk Management Assessment would cover for your plans, and whether Cowbell’s placement includes any plan-review service (its reviewed pages do not describe one). [8](https://www.heffins.com/family-office/ "Family Office") [3](https://www.zurichna.com/insurance/excess-and-surplus/small-business-management-liability "Small and Midsize Business Management Liability | Zurich Select Plus")

## Offering Details

| Criteria | Cowbell / Zurich Select Plus Fiduciary Liability | Heffernan Fiduciary Liability Insurance |
| --- | --- | --- |
| Role in This Line | Fiduciary liability is one module within Cowbell's distribution of Zurich's Select Plus management liability product; Cowbell operates the platform, Zurich underwrites the module.

[4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [3](https://www.zurichna.com/insurance/excess-and-surplus/small-business-management-liability "Small and Midsize Business Management Liability | Zurich Select Plus") (Evidence: Company-reported; scope: Management liability page intro and module list; Zurich page module-name section..) | Heffernan places fiduciary liability coverage within its general corporate/executive-protection lineup and again within a dedicated family-office and financial-institution practice.

[7](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [8](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Business Insurance and Family Office page listings; no dedicated fiduciary-liability product page was found..) |

Zurich's site footer names 'Zurich American Insurance Company' in its copyright notice, but neither page states that entity is the specific policy issuer for this module. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [3](https://www.zurichna.com/insurance/excess-and-surplus/small-business-management-liability "Small and Midsize Business Management Liability | Zurich Select Plus") (Evidence: Company-reported; scope: Management liability page intro; Zurich page intro and footer..) | The reviewed pages do not name the insurer or insurers that issue fiduciary liability policies Heffernan places for either business clients or family offices. [7](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [8](https://www.heffins.com/family-office/ "Family Office") (Evidence: Not publicly disclosed; scope: Business Insurance and Family Office pages as read on 2026-09-23..) |

[7](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [8](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Direct practice-page listings; no minimum size or asset-under-management threshold was published for the coverage specifically..) |
| Coverage Features | Cowbell describes fiduciary liability as protecting against claims arising from breaches of fiduciary duties related to employee benefit plans, such as a company's 401(k) or health plan. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") (Evidence: Company-reported; scope: FAQ 'What is the difference between management liability and D&O?'..) | On the family-office page, fiduciary liability insurance is listed alongside directors and officers, professional liability, employment practices liability, trustee liability, and other management-liability-adjacent lines as coverage the practice can arrange, without describing the policy's insuring agreement or exclusions. [8](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Family Office page as read on 2026-09-23..) |
| Limits and Retentions | Neither the Cowbell page nor Zurich's own Select Plus page, both read in full, publishes fiduciary-liability limit or retention amounts. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [3](https://www.zurichna.com/insurance/excess-and-surplus/small-business-management-liability "Small and Midsize Business Management Liability | Zurich Select Plus") (Evidence: Not publicly disclosed; scope: Cowbell page and Zurich page, both read on 2026-09-23..) | Neither page publishes a fiduciary-liability limit, retention, or premium range. [7](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [8](https://www.heffins.com/family-office/ "Family Office") (Evidence: Not found in reviewed sources; scope: Business Insurance and Family Office pages as read on 2026-09-23..) |
| Risk Services | Both Cowbell and Zurich describe the Select Plus product generally as backed by 'the reputable Zurich Claims service'; neither reviewed page describes a fiduciary-specific service such as plan-compliance consulting. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [3](https://www.zurichna.com/insurance/excess-and-surplus/small-business-management-liability "Small and Midsize Business Management Liability | Zurich Select Plus") (Evidence: Not publicly disclosed; scope: Management liability page intro; Zurich page intro, both read on 2026-09-23..) | Heffernan's family-office practice describes a Risk Management Assessment: itemizing a client's structures, assets, and exposures; crafting insurance and risk-management strategies to close coverage gaps; and helping navigate claims, for its fiduciary and financial-institution client base. [8](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Family Office page as read on 2026-09-23; a company-described service, not a measured outcome..) |
| How to Apply | This fiduciary module is accessed only by appointed Zurich E&S wholesalers through the Cowbell platform's API; it is not sold directly to businesses. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") (Evidence: Company-reported; scope: FAQ 'How can I access the Zurich Select Plus management liability product through Cowbell?'..) | The family-office practice's fiduciary-liability coverage is reached through a named Private Client Group specialist contact rather than a self-service online quote flow. [8](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Family Office page as read on 2026-09-23; the general business-insurance page's fiduciary listing routes through Heffernan's general Contact Us form instead..) |
