# At-Bay vs Kinro Professional Liability (E&O) Insurance

Kinro collects a broad quote-file intake across several coverage lines; At-Bay's MPL page centers on a specific list of policy features.

## Research Scope and Use

Use this comparison to evaluate At-Bay and Kinro for Professional Liability (E&O) 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

Kinro says it gathers services, client types, revenue, prior claims, and retroactive dates for an E&O quote, often reviewed together with cyber, general liability, and D&O. At-Bay's MPL page instead centers on specific policy features, including an 80/20 hammer clause and automatic coverage for acquired subsidiaries.

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

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [11](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [12](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [13](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [14](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

### A Line-Specific Feature List Versus a Cross-Line Intake

At-Bay's MPL page lists specific policy features on their own: automatic coverage for acquired subsidiaries, independent-contractor coverage, and an 80/20 hammer clause. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") Kinro instead frames professional liability/E&O as one line typically reviewed together with cyber, general liability, and D&O, collecting revenue, prior claims, and retroactive dates as part of a broader submission. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O")

### Who Underwrites Versus Who Routes the Business

At-Bay names MPL as one of its own products, distributed through its disclosed producer, At-Bay Insurance Services LLC. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [4](https://www.at-bay.com/licenses/ "Licenses") Kinro says it matches a business to a carrier rather than underwriting the policy itself, noting the product "can underwrite differently" depending on the operation and carrier appetite. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O")

### What Neither Page Publishes

At-Bay's current MPL page does not name the insurer that would issue a new policy. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") Kinro's reviewed page also does not publish limits, retentions, or premiums, saying those amounts would appear on a quote. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O")

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

- Ask Kinro which carrier it would route your submission to and what that carrier's appetite covers. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O")
- Ask At-Bay for the insurer issuing your MPL policy, since the current page does not name one. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Ask At-Bay for its published $5 million limit ceiling and applicable state restrictions. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Ask Kinro for a specific limit and retention figure once it has your quote-file information. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O")
- Confirm whether Kinro would review your E&O alongside cyber, general liability, or D&O, and how that affects pricing. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O")

## Offering Details

| Criteria | At-Bay Miscellaneous Professional Liability (MPL) Insurance | Kinro Professional Liability / E&O |
| --- | --- | --- |
| Role in This Line | At-Bay markets MPL as one of its own named insurance products, sold through its disclosed producer, At-Bay Insurance Services LLC, with the product page directed at "properly licensed insurance professionals" submitting business rather than at direct retail buyers. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [4](https://www.at-bay.com/licenses/ "Licenses") (Evidence: Company-reported; scope: Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk..) | Kinro is a broker: it matches a business to a professional liability/E&O carrier rather than underwriting the policy itself, saying the product "can underwrite differently" by operation and that market fit depends on carrier appetite. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page "Routing" and "Market fit" sections..) |
| Issuing Insurer | The current MPL product page does not name the insurer that issues the policy. A September 2023 press release named United Specialty Company in connection with MPL, but that historical reference does not establish the current issuing insurer for a new MPL quote. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [5](https://www.at-bay.com/press_releases/at-bay-doubles-mpl/ "At-Bay Doubles Miscellaneous Professional Liability Appetite") (Evidence: Not found in reviewed sources; scope: Reviewed MPL page as of 2026-09-23 and the September 2023 press release; restates the existing provider fact that MPL's current issuer is unresolved, distinct from the August 2023 Cyber/Tech E&O transition to At-Bay Specialty Insurance Company paper..) | Not described in the reviewed sources. |
| Who It’s For | At-Bay says it provides primary MPL for businesses of all revenue sizes with limits up to $5 million, subject to state restrictions and eligibility requirements detailed in a separate MPL appetite guide. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record..) | Kinro says this coverage commonly fits consultants, agencies, tech services and professional firms, and typically comes up when clients rely on the business's professional advice or deliverables, or a contract requires E&O or professional liability. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page "Common fit" and "Triggers" sections..) |
| Coverage Features | At-Bay lists MPL coverage highlights including automatic coverage for acquired subsidiaries, claims-made-and-reported coverage, coverage for independent contractors, disciplinary-proceedings defense, a duty-to-defend contract, personal-injury coverage (including emotional distress), punitive damages where insurable, a professional-services definition written for each insured, and an 80/20 hammer clause. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Product-page coverage-highlights list; an 80/20 hammer clause is a settlement provision where the insurer pays 80% and the insured pays 20% of costs after the insured declines a recommended settlement. The issued policy and declarations control actual wording, limits and exclusions..) | Kinro describes professional liability/E&O as addressing claims tied to alleged errors, omissions, missed deadlines or service mistakes, and says it covers defense and claim-handling questions that a general liability policy may not address. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page introduction and "Coverage" section; actual terms depend on the carrier and policy placed..) |
| Limits and Retentions | At-Bay publishes an MPL limit ceiling of up to $5 million, with state restrictions that are not detailed on the product page itself. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant..) | The reviewed page does not publish limits, retentions or premiums for professional liability/E&O; amounts would appear on a quote. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Not found in reviewed sources; scope: Professional Liability / E&O page as read on 2026-09-23..) |
| How to Apply | At-Bay directs MPL submissions to underwriting by email or through automatic quotes on its Broker Platform, which At-Bay describes as a workflow of creating a quote, customizing limits and retentions, and binding the policy. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") (Evidence: Company-reported; scope: Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed..) | To quote professional liability/E&O, Kinro collects the services provided, client types, revenue and contract terms, prior claims and retroactive dates, and whether the business handles regulated, technical, financial or operational advice, and often reviews it together with cyber, general liability and D&O coverage. [10](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page "Quote file" and "Reviewed with" sections..) |
