## What Is Coalition Insurance?

Coalition fits businesses that want cyber insurance bundled with free attack-surface monitoring and alerts, and technology companies that want Tech E&O alongside it. You can't buy it online yourself: you need an appointed broker, and the final price isn't published.

## What Is Professional Errors and Omissions (E&O) Insurance?

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### Cyber Attachment or Business Owners Policy

Coalition makes miscellaneous professional liability an add-on to an Active Cyber Insurance quote, so the published route ties this E&O option to its cyber product. THREE presents E&O as a category within its combined Business Owners Policy. Choose whether to start with cyber or assess E&O within a small-business package, then confirm it appears in the quote. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### Defense Promise and What the Quote Must Specify

Coalition says its MPL covers defense costs, settlements and judgments for professional-service errors on a duty-to-defend basis. THREE's product page lists E&O but does not state a separate limit or deductible, directing buyers to the quote summary. Compare MPL terms attached to cyber with THREE's quoted E&O amount and deductible. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask Coalition to quote the MPL with Active Cyber and provide its separate E&O limit, deductible and any conditions tied to the cyber policy. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability")
- Ask THREE to confirm E&O is selected, then identify the separate E&O limit and deductible in the quote summary. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")
- Compare whether Coalition's duty-to-defend wording and THREE's issued form address your specific professional services and allegations. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")
- Ask each provider to identify the issuer shown on your declarations; THREE's linked sample names Berkshire Hathaway Direct Insurance Company, while Coalition's MPL page does not identify a carrier. [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") [6](https://www.coalitioninc.com/legal/disclaimer "U.S. Disclaimers")

## Offering Details

| Criteria | Coalition Miscellaneous Professional Liability (MPL) | THREE Business Owners Policy |
| --- | --- | --- |
| Role in This Line | Coalition designs and distributes MPL as an add-on coverage that combines with certain Active Cyber Insurance policies, sold through appointed brokers. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") (Evidence: Company-reported; scope: Miscellaneous Professional Liability product page as read on 2026-09-23..) | THREE presents Errors and Omissions as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant..) |
| Issuing Insurer | Coalition's disclaimer page has named sections for admitted cyber, non-admitted cyber, and admitted executive risk, but no equivalent 'Admitted MPL' section, indicating MPL is placed on a non-admitted (surplus lines) basis with unaffiliated insurers the disclaimer does not name. [6](https://www.coalitioninc.com/legal/disclaimer "U.S. Disclaimers") (Evidence: Not publicly disclosed; scope: U.S. Disclaimers page as read on 2026-09-23; the buyer's declarations page names the actual issuing insurer..) | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy..) |
| Who It’s For | Coalition markets MPL to any business that performs professional services, naming examples such as consultants, marketing and PR firms, staffing firms, printers, interior decorators, photographers and videographers, and property managers. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") (Evidence: Company-reported; scope: Miscellaneous Professional Liability product page as read on 2026-09-23..) | The reviewed product page does not state separate eligibility rules for Errors and Omissions; the general quote and advisor route is not proof that a particular business qualifies for it. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [7](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms..) |
| Coverage Features | Coalition says MPL covers defense costs, settlements, judgments, and other expenses from claims of errors and omissions in professional services, including negligence, failure to provide service, and misstatements about the service performed, on a duty-to-defend basis even when the business is not ultimately at fault. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") (Evidence: Company-reported; scope: Miscellaneous Professional Liability product page as read on 2026-09-23; the issued policy controls actual terms..) | THREE's Business Owners Policy page lists Errors & Omissions among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Official THREE package marketing for Errors and Omissions. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy..) |
| Limits and Retentions | Confirm in your quote. | The reviewed public product page does not state a separate limit or deductible for Errors and Omissions; THREE says the quote-specific insurance summary lists limits and deductibles. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible..) |
| How to Apply | Coalition sells MPL only as an addition to an Active Cyber Insurance quote, saying it takes just a few extra questions to add, rather than as a stand-alone policy. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") (Evidence: Company-reported; scope: Miscellaneous Professional Liability product page as read on 2026-09-23..) | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. [7](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the route for the overall THREE product. It does not show whether Errors and Omissions will be offered for a particular business or whether a customer can bind that line without an issued policy..) |
| Claims Support | Coalition says its in-house claims team manages both MPL and cyber claims in one place, which it describes as a smoother, more coordinated process for the policyholder. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") (Evidence: Company-reported; scope: Miscellaneous Professional Liability product page as read on 2026-09-23; speed and efficiency descriptions are company-reported and not independently verified..) | Confirm in your quote. |
