Key Differences in Professional Liability (E&O) Insurance

How You Reach Coverage

Alliance Risk places professional liability as a broker, describing itself as backing placements with risk-specific underwriting input and carrier partnerships it does not name. 3

At-Bay markets Miscellaneous Professional Liability (MPL) as one of its own named insurance products, sold through its disclosed producer At-Bay Insurance Services LLC, with the reviewed page addressed to licensed insurance professionals submitting business rather than direct retail buyers. 6 7

What the Base Policy Lists

At-Bay's MPL page itemizes specific policy features: automatic coverage for acquired subsidiaries, coverage for independent contractors, disciplinary-proceedings defense, a duty-to-defend contract, and an 80/20 hammer clause. Alliance Risk's page instead describes coverage in general terms — negligent acts, breach of contract, misrepresentation and missed deadlines — while listing exclusions such as bodily injury, intentional wrongdoing and cyber incidents that point buyers to other lines. 6 3

Limits and How You Apply

At-Bay publishes an explicit limit ceiling for MPL:

At-Bay publishes an MPL limit ceiling of up to $5 million, with state restrictions that are not detailed on the product page itself. 6Company-reported. Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant.

Alliance Risk's reviewed page gives no comparable limit figures, only illustrative cost ranges by firm size, and its only listed application route is a generic quote request rather than At-Bay's Broker Platform workflow of creating, customizing and binding a quote. 3 9

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

  • Ask At-Bay which insurer will issue the policy, since its current MPL page does not name one. 6
  • Ask Alliance Risk which specific carrier it is placing your professional liability policy with. 3
  • Confirm your actual limit needs against At-Bay's published $5 million ceiling and Alliance Risk's firm-size-based cost estimate. 6 3
  • Ask Alliance Risk for the specific submission information it needs, since its page does not list one the way At-Bay's Broker Platform does. 3

Offering Details

Alliance Risk vs At-Bay Professional Liability (E&O) Insurance: documented features by provider

CriteriaAlliance Risk Professional Liability InsuranceAt-Bay Miscellaneous Professional Liability (MPL) Insurance
Role in This Line

Alliance Risk places professional liability (errors and omissions, or E&O) coverage as a broker, saying it backs placements with risk-specific underwriting input and carrier partnerships rather than underwriting the policy itself. 3Company-reported. Professional liability product page.

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. 6,7Company-reported. Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk.

Issuing Insurer

The reviewed professional liability page does not name the insurer that would issue a policy; it refers generally to 'strong carrier partnerships' without identifying a specific carrier. 3Not publicly disclosed. Professional liability product page as read on 2026-09-23.

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. 6,8Not 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.

Who It’s For

Alliance Risk targets professional liability at consultants and advisory firms, accountants and tax professionals, architects and engineers, real estate and insurance agents and brokers, marketing and PR agencies, IT and technology consultants, healthcare providers, and financial planners and investment advisors. 3Company-reported. Professional liability product page; eligibility for a particular company depends on underwriting.

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. 6Company-reported. Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record.

Coverage Features

Alliance Risk lists negligent acts or omissions, breach of contract, misrepresentation, and missed deadlines as typically covered, and says bodily injury or property damage, intentional wrongdoing or fraud, employment disputes, cyber incidents, and prior known claims are excluded and belong to other lines such as general liability, EPLI or cyber liability. 3Company-reported. Professional liability product page; coverage and exclusions described in general terms, subject to the policy as issued.

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. 6Company-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.

Limits and Retentions

The reviewed professional liability page gives cost ranges by firm size (for example, solo practitioners at $500-$3,000 a year up to mid-sized to large firms at $10,000-$50,000-plus) but does not publish specific coverage limits, retentions or deductible amounts for this line. 3Not found in reviewed sources. Professional liability product page as read on 2026-09-23; cost figures are illustrative premium estimates, not published limits.

At-Bay publishes an MPL limit ceiling of up to $5 million, with state restrictions that are not detailed on the product page itself. 6Company-reported. Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant.

Risk Services

Alliance Risk describes its approach to professional liability as including industry-specific risk reviews, claims-trend analysis, customized policy language, review of client contracts to limit personal exposure, and expertise structuring claims-made policies including tail coverage, prior acts and retroactive dates. 3Company-reported. Professional liability product page, Our Approach to Professional Liability and The Alliance Risk Difference sections.

Not described in the reviewed sources.

How to Apply

The professional liability page's only application route is a generic 'Get a quote' request; it does not list the specific submission information Alliance Risk asks for on this line, unlike its D&O, EPLI and fiduciary product pages. 3Not found in reviewed sources. Professional liability product page as read on 2026-09-23.

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. 6,9Company-reported. Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed.

Claims Support

Alliance Risk says professional liability clients get access to a legal network and claims experts who understand the client's industry, providing a defense strategy if a claim arises. 3Company-reported. Professional liability product page, The Alliance Risk Difference section.
