At-Bay vs
Hiscox Professional Liability (E&O) Insurance
Hiscox names its own admitted underwriter for professional liability; At-Bay's current MPL page leaves the issuing insurer unresolved.
What Is At-Bay Insurance?
At-Bay offers Cyber, Tech E&O, and miscellaneous professional liability insurance through its disclosed insurance agency and surplus lines broker. Its Stance security services have policy eligibility conditions, with managed detection and response sold separately. 1,2
What Is Hiscox?
Hiscox is a U.S. small-business insurance brand whose website is operated by Hiscox Inc., a Delaware producer that does business in California as Hiscox Insurance Agency. Eligible firms can quote general liability, professional liability, cyber and a business owner’s policy online; other advertised lines are often placed with partner insurers, so the issuing company on each quote still has to be checked. 7,8,9
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. 13,14,15,16
Key Differences in Professional Liability (E&O) Insurance
A Named Underwriter Versus an Open Question
At-Bay's current MPL product page does not name the insurer for a new quote; a 2023 press release referenced a different At-Bay entity for a separate coverage transition, which does not establish MPL's current issuer. 3 5 Hiscox's materials take the opposite approach:
Hiscox's appetite guide and About Hiscox US page name Hiscox Insurance Company Inc. (NAIC 10200) as the underwriter of admitted Hiscox NOW professional-liability policies. 12,9Company-reported. Admitted small-business professional liability as described in company materials; the exact contracting entity for a particular state or channel should be confirmed on the quote.
Between the two, only Hiscox's reviewed pages point a buyer to a specific underwriting entity to check against a declarations page. 3
Direct Online Sale Versus Producer Submission
Hiscox sells professional liability directly online to small businesses in 49 states and D.C. (excluding Alaska), with a specialist broker available where it doesn't sell online in a state. 10 At-Bay instead distributes MPL through its own disclosed producer, At-Bay Insurance Services LLC, so the policy is placed by a submitting agent rather than bound directly online. 3 4
Claims-Made Structure and Eligibility Ceiling
Hiscox describes professional liability as a claims-made policy: covered only if the claim is made and typically reported while the policy is active. 11 At-Bay says it provides primary MPL with limits up to $5 million for businesses of all revenue sizes, subject to state restrictions in a separate appetite guide. 3
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Confirm Hiscox Insurance Company Inc. is the specific entity on your declarations, since the exact contracting entity can vary by channel. 12
- Ask At-Bay directly which insurer would issue your MPL policy. 3
- Ask whether Hiscox sells professional liability online in your state or requires a specialist broker. 10
- Neither company publishes standard limit or retention amounts on the reviewed pages; ask both for a specific quote. 10 3
- Ask about At-Bay's state restrictions tied to its $5 million ceiling before assuming your state qualifies. 3
Offering Details
At-Bay vs Hiscox Professional Liability (E&O) Insurance: documented features by provider
| Criteria | At-Bay Miscellaneous Professional Liability (MPL) Insurance | Hiscox Professional Liability Insurance |
|---|---|---|
| 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. 3,4Company-reported. Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk. | Hiscox Inc., a licensed insurance intermediary, sells professional liability (errors and omissions) coverage directly online to small businesses as part of its Hiscox NOW admitted small-business catalogue. 9,10Company-reported. Company-stated online small-business channel. |
| 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. 3,5Not 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. | Hiscox's appetite guide and About Hiscox US page name Hiscox Insurance Company Inc. (NAIC 10200) as the underwriter of admitted Hiscox NOW professional-liability policies. 12,9Company-reported. Admitted small-business professional liability as described in company materials; the exact contracting entity for a particular state or channel should be confirmed on the quote. |
| 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. 3Company-reported. Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record. | Hiscox says professional liability is licensed for sale in 49 states and Washington, D.C., excluding Alaska, and that if it does not sell the product online in a buyer's state, a specialist broker may be able to help instead. 10,12Company-reported. Company-stated jurisdiction for the online small-business catalogue; the appetite guide's technology classes (IT consultants, software development) illustrate typical buyers but do not guarantee acceptance for any one applicant. |
| 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. 3Company-reported. 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. | Hiscox describes professional liability as a claims-made policy, meaning a claim is covered only if it is made (and typically reported) while the policy is active, rather than an occurrence policy covering incidents regardless of when the claim surfaces. 11Company-reported. Product FAQ description; exact triggers, retroactive dates, exclusions and wording are set by the issued policy. |
| 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. 3Company-reported. Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant. | The professional-liability pages reviewed do not publish standard limit, retention or deductible amounts; specific figures are shown only on a quote. 10,11Not publicly disclosed. Public product and FAQ pages as previously reviewed. |
| 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. 3,6Company-reported. Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed. | Hiscox says eligible buyers can quote and buy professional liability online, with licensed advisors available by phone during posted hours for questions during the process. 10Company-reported. Company-described online application; eligibility and binding conditions require confirmation on the actual application. |
| Claims Support | Not described in the reviewed sources. | A professional-liability FAQ tells current customers that the claims phone line is open 24 hours a day, 7 days a week, separate from the general claims-center hours listed elsewhere on the Hiscox site. 11Company-reported. Company-described claims-reporting availability for this product's FAQ; does not establish claim outcomes or turnaround time. |
