At-Bay vs Nationwide: How Do They Compare for Professional Liability (E&O) Insurance?

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. ^3,4Company-reported. Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk.

Nationwide describes offering professional errors omissions for the audience stated on the cited product page. ¹⁰Company-reported. professional errors omissions marketed by nationwide; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement.

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 A September 2023 press release named United Specialty Company in connection with MPL, but that historical reference does not establish the current issuing insurer for a new MPL quote. ^3,5Not found in reviewed sources. 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.
