## What Is Management Liability Insurance?

Management liability packages can combine D&O and employment-practices coverage for leader and workplace claims, while benefit-plan protection may be a separate part.

## What Are the Key Differences Between Cowbell and Liberty Mutual Management Liability Insurance?

### Who can access the product

Cowbell says Zurich Select Plus is available through its platform to Zurich-appointed excess-and-surplus wholesalers, not directly to businesses. The wholesaler uses API access after appointment. Liberty Mutual describes ProShield as a package for private and not-for-profit organizations, without the same wholesaler-only restriction in the reviewed claims. This distinction changes the buyer’s first step: identify an appointed wholesaler for Select Plus, while asking Liberty Mutual how its package reaches the applicant. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [7](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")

### Modules and terms

Select Plus allows up to four named modules: private management and company liability, employment-practices and third-party discrimination liability, fiduciary, and crime. Liberty Mutual lists D&O, employment-practices, fiduciary and crime in ProShield. The line labels overlap, but the names do not establish matching definitions, aggregates or exclusions. Buyers should compare each module’s policy wording and confirm the issuing insurer and limit structure in both proposals. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [7](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")

## What Should You Confirm in Cowbell and Liberty Mutual Management Liability Insurance Quotes?

- Ask the wholesaler to confirm Zurich appointment, eligible states and the issuing Zurich entity for Select Plus.
- Ask Liberty Mutual for ProShield’s module definitions, issuing entity and schedule of limits and exclusions.

## Cowbell vs Liberty Mutual Management Liability Insurance Compared

| Criteria | Cowbell / Zurich Select Plus Management Liability | Liberty Mutual ProShield Management Liability |
| --- | --- | --- |
| Role in This Line | Cowbell is the distribution platform, not the insurer: it gives Zurich-appointed E&S wholesalers API access to Zurich's Select Plus management liability product, a modular suite Zurich already sells to larger companies, sized down for small and midsize private businesses. Zurich's own page confirms Select Plus is 'Zurich Insurance, in collaboration with Cowbell,' offered as a 'proprietary form,' with identical FAQ wording to Cowbell's page. [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: Cowbell intro paragraph and FAQ; Zurich intro and 'Delivering speed from quoting to policy issuance' section..) | Liberty Mutual markets ProShield as a management-liability package combining D&O, employment-practices, fiduciary and crime coverages. [7](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [8](https://business.libertymutual.com/industries/professional-services/ "Professional services") (Evidence: Company-reported; scope: Liberty Mutual’s cited product or program overview documents this description. It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) |
| Issuing Insurer | Both Cowbell and Zurich say the product is offered on Zurich admitted paper and backed by 'the reputable Zurich Claims service.' Neither page names the specific underwriting Zurich subsidiary or policy-issuing entity; Zurich's site footer copyright reads 'Zurich American Insurance Company,' but that is a general site-wide notice, not a stated policy-issuer confirmation for Select Plus specifically. [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..) | Confirm in your quote. |
| Who It’s For | Cowbell says the product targets SME private companies with under 250 employees and under $50M in assets, and lists target industries including specialty chemicals, technology, energy/utilities, construction, manufacturing, hospitality, retail, and integrated freight & logistics. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") (Evidence: Company-reported; scope: FAQ 'What size accounts are targeted?' and 'Target industries' list..) | The ProShield page identifies private and not-for-profit organizations as its intended audiences; industry-page listings do not establish universal eligibility. [7](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [8](https://business.libertymutual.com/industries/professional-services/ "Professional services") (Evidence: Company-reported; scope: Liberty Mutual’s cited product or program overview documents this description. It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) |
| Coverage Features | Zurich's own page names the four Select Plus modules as 'Private Management and Company Liability,' 'Employment Practices and Third-Party Discrimination Liability,' 'Fiduciary Liability,' and 'Crime Insurance' -- broader labels than the plain 'D&O' and 'EPL' shorthand Cowbell's FAQ uses -- and says a buyer can combine up to four of these modules into one policy. [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: Zurich page 'Protect your small to midsize business with Zurich's Select Plus Management Liability solutions' section..)<br><br>Cowbell describes management liability as a modular umbrella covering four lines within the Select Plus product: private company D&O, employment practices liability, fiduciary liability, and crime, each addressing a different category of management or employee risk. [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?'..) | The page describes selected features for the component lines, but does not establish the terms, limits or exclusions in an individual ProShield policy. [7](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [8](https://business.libertymutual.com/industries/professional-services/ "Professional services") (Evidence: Company-reported; scope: Liberty Mutual’s cited product or program overview documents this description. It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) |
| Limits and Retentions | Neither the Cowbell page nor Zurich's own Select Plus page publishes limit or retention amounts for the modules; both were read in full and neither discloses a figure. [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..) | The cited public overview does not establish the limits, deductibles, exclusions or form terms that would apply to a specific buyer. [7](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [8](https://business.libertymutual.com/industries/professional-services/ "Professional services") (Evidence: Not publicly disclosed; scope: Ask for the quote and specimen or issued policy forms before treating a listed feature as covered..) |
| Risk Services | Cowbell says the product is backed by Zurich's claims service, and frames the offering's advantage as faster quoting and issuance through Cowbell's technology platform compared with Zurich's standard process, rather than describing separate risk-control services. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") (Evidence: Company-reported; scope: Page intro and FAQ 'What makes the Zurich Select Plus offering through Cowbell unique?'..) | Liberty Mutual describes ProShield as one package policy that combines multiple management-liability coverages and is designed to reduce the need for separate endorsements. [7](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [8](https://business.libertymutual.com/industries/professional-services/ "Professional services") (Evidence: Company-reported; scope: Liberty Mutual’s cited product or program overview documents this description. It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) |
| How to Apply | Access is limited to appointed wholesalers of Zurich Excess & Surplus (E&S): a wholesaler already appointed by Zurich E&S can reach the product through the Cowbell platform via API, and is directed to contact a Cowbell or Zurich representative to set that up. The product 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?'..) | Confirm in your quote. |
| Claims Support | Cowbell says the most common management liability claims fall under employment practices liability, citing discrimination, wrongful termination, harassment, and retaliation as the most frequent claim types. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") (Evidence: Company-reported; scope: FAQ 'What is the most common management liability claim?'; describes claim frequency, not Cowbell's own claims-handling process..) | Confirm in your quote. |
