At Bay vs Mylo: Professional Liability / E&O Insurance

A business that wants someone to compare quotes from several insurers fits Mylo, which brokers professional liability and does not underwrite it. At-Bay markets its own miscellaneous professional liability up to $5 million, with its page aimed at licensed insurance professionals.

Kearny Risk organizes these comparisons for firms whose advice, content or technology creates professional exposures.Research updated 2026-09-25

Mylo explains both claims-made and occurrence E&O, including tail coverage; At-Bay describes its MPL as claims-made-and-reported.

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

Compare Claims-Made and Occurrence Forms

Mylo explains both claims-made and occurrence E&O, including how tail coverage can extend the reporting period after a claims-made policy ends. At-Bay states that its MPL is claims-made-and-reported but does not compare it with an occurrence form. If you have past work to cover, ask how each quote treats prior acts and late-reported claims. [8] [4]

Broker Comparison or Product Submission

Mylo says it compares professional-liability quotes from multiple business insurers. At-Bay offers its own MPL product through its producer and broker submission channels. Mylo may help you compare providers; At-Bay gives you a named product to submit. [8] [3]

Identify the Carrier

Neither reviewed page names the insurer for your policy. Mylo’s carrier directory groups contacts generally rather than identifying an E&O carrier; At-Bay’s MPL page also leaves the issuer unnamed. Get the carrier and claims contact from your quote. [7] [4]

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

  • Ask Mylo whether its quote options are claims-made, occurrence or both, and what tail coverage costs. [8]
  • Ask At-Bay which insurer will issue the MPL and what retroactive date applies. [4]
  • Request the specific carrier and claims-reporting process for either policy. [7] [4]
  • Compare actual limits, retentions and premium. [8] [4]

Areas of coverage

At-Bay

  • role: 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. Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk.company-reportedSource ↗Source ↗
  • 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. 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-foundSource ↗Source ↗
  • eligibility: 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. Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record.company-reportedSource ↗
  • coverage: 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. 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.company-reportedSource ↗
  • 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. Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant.company-reportedSource ↗
  • application: 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. Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed.company-reportedSource ↗Source ↗

Mylo

  • role: Mylo brokers professional liability insurance by comparing quotes from multiple business insurance companies rather than underwriting the policy itself. Professional liability product page.company-reportedSource ↗
  • eligibility: Mylo markets this line to businesses that could face a claim from a client unhappy with their professional services, using examples spanning app development, financial planning and beauty-salon services. Product page examples; a particular business's eligibility depends on underwriting.company-reportedSource ↗
  • coverage: Mylo describes the policy responding to breach-of-contract claims, bodily injury or property damage claims, financial-loss claims, and consequential-damages claims arising from a client relationship. Product page coverage descriptions; actual insuring agreements and exclusions are set by the issued policy.company-reportedSource ↗
  • coverage: Mylo explains that professional liability comes in claims-made and occurrence forms, and that tail coverage can be added to a claims-made policy to extend reporting after it ends. Product page FAQ; which form and tail terms are offered depends on the placed carrier.company-reportedSource ↗
  • insurer: The professional liability product page and Mylo's carrier-contact directory do not name the insurer that would issue a professional liability policy; the directory groups carriers under generic Auto & Home and Business categories only. Checked the professional liability product page and the carrier-contact directory on 2026-09-23; neither ties a named carrier to this line.not-disclosedSource ↗Source ↗
  • application: Mylo says it recommends coverage customized to the business and compares professional liability quotes from top-rated business insurance companies to find a combination of coverage and price. Product page "How will Mylo find me the right policy?" section.company-reportedSource ↗
  • claims: Mylo's carrier-contact page lists claims phone numbers by carrier for Auto & Home and Business policies generally, but does not identify a professional-liability-specific claims contact or process. Carrier-contact directory checked 2026-09-23; entries are organized by carrier and general product category, not by coverage line.not-foundSource ↗
