Key Differences in Professional Liability (E&O) Insurance
Explaining Policy Forms Versus Stating One
Mylo's professional liability FAQ explains that coverage comes in both claims-made and occurrence forms, and that tail coverage can be added to a claims-made policy to extend reporting after it ends. 9 At-Bay's MPL page states its coverage is written on a claims-made-and-reported basis as one feature among several, without contrasting it against an occurrence alternative. 3
How Each Company Shops the Business
Mylo compares professional liability quotes from multiple business insurance companies to find a combination of coverage and price, rather than underwriting the policy itself. 9 At-Bay names MPL as one of its own products, distributed through its disclosed producer, At-Bay Insurance Services LLC, rather than shopping the business across carriers. 3 4
What Neither Company's Pages Name
Mylo's professional liability page and its carrier-contact directory do not name the insurer that would issue a policy, and the directory groups carriers under generic categories rather than by coverage line. 9 At-Bay's current MPL page likewise does not name an issuing insurer. 3
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Mylo whether the quotes it compares for you are claims-made, occurrence, or a mix, and what tail coverage would cost. 9
- Ask At-Bay directly which insurer would issue your MPL policy. 3
- Ask Mylo which specific carrier it selected for your quote and why. 9
- Ask At-Bay for its published $5 million limit ceiling and applicable state restrictions. 3
- Ask Mylo for its claims-reporting process for professional liability specifically, since its carrier directory does not break this out by coverage line. 10

At-Bay vs Mylo Professional Liability (E&O) Insurance: documented features by provider
| Criteria | At-Bay Miscellaneous Professional Liability (MPL) Insurance | Mylo 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. | Mylo brokers professional liability insurance by comparing quotes from multiple business insurance companies rather than underwriting the policy itself. 9Company-reported. Professional liability product page. |
| 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. | 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. 9,10Not publicly disclosed. Checked the professional liability product page and the carrier-contact directory on 2026-09-23; neither ties a named carrier to this line. |
| 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. | 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. 9Company-reported. Product page examples; a particular business's eligibility depends on underwriting. |
| 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. | 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. 9Company-reported. Product page coverage descriptions; actual insuring agreements and exclusions are set by the issued policy. 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. 9Company-reported. Product page FAQ; which form and tail terms are offered depends on the placed carrier. |
| 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. | Not described in the reviewed sources. |
| 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. | 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. 9Company-reported. Product page "How will Mylo find me the right policy?" section. |
| Claims Support | Not described in the reviewed sources. | 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. 10Not found in reviewed sources. Carrier-contact directory checked 2026-09-23; entries are organized by carrier and general product category, not by coverage line. |
