## What Are the Key Differences Between At-Bay and Founder Shield Professional Liability (E&O) Insurance?

### Underwriter Versus Placement Broker

At-Bay names Miscellaneous Professional Liability (MPL) as one of its own insurance products, distributed through its disclosed producer, At-Bay Insurance Services LLC. [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [2](https://www.at-bay.com/licenses/ "Licenses") Founder Shield describes its own role differently:

Founder Shield is a retail insurance brokerage, described on its site as “the innovation arm of The Baldwin Group,” and places Founder Shield Errors & Omissions Insurance with third-party carriers rather than underwriting the policy itself. [6](https://foundershield.com/about-us/ "About Us") (Evidence: Company-reported; scope: About-us page; applies to Founder Shield's brokerage model generally, restated here for this line..)

### What Each Company Discloses About the Carrier

At-Bay's current MPL page does not name the insurer that issues the policy for a new quote. [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") Founder Shield says it places policies, including this one, only with carriers rated A- or better by AM Best, matched to the client's industry, though it does not name the carrier for any specific placement. [7](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?")

### How Coverage Is Packaged

At-Bay's MPL page lists specific insuring-agreement features on its own, separate from any other coverage line. [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") Founder Shield says E&O is often packaged with technology E&O and cyber coverage since the two types of claims tend to intertwine. [5](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance")

## What Should You Confirm in At-Bay and Founder Shield Professional Liability (E&O) Insurance Quotes?

- Ask Founder Shield which specific A-rated carrier it plans to approach for your E&O placement. [7](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?")
- Confirm whether Founder Shield would bundle your E&O with technology E&O and cyber, or place it as a standalone policy. [5](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance")
- Ask At-Bay for its published $5 million limit ceiling and any state restrictions on your business. [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Ask Founder Shield for specific limit and premium figures, since none are published on its coverage page. [5](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance")
