At-Bay vs Heffernan Insurance Brokers

At-Bay offers cyber, technology errors and omissions (Tech E&O), and miscellaneous professional liability insurance. Its disclosed producer, At-Bay Insurance Services LLC, is a property and casualty agency and surplus lines broker; its website says coverage is underwritten by non-admitted insurers. ^1,5

Heffernan describes itself as an insurance broker and risk manager that shops markets, presents options, and places coverage with insurance carriers. It is not identified in the reviewed pages as the insurer that issues or pays claims on a buyer’s policy. Privacy language says it may share underwriting information with non-affiliated parties to solicit quotations from insurance carriers. ^19,22,18,14

Public pages and a 26 August 2026 company release use the name Heffernan Insurance Brokers and display California license number 0564249. They identify F. Michael Heffernan as President and CEO. The reviewed official pages do not print a longer corporate legal name such as an “Inc.” suffix. Confirm the contracting producer name on the engagement agreement and policy. ^14,37,15

Heffernan’s current site says it has been independent and employee-owned since 1988. A 2019 SkyKnight Capital announcement described a minority investment that recapitalized Heffernan’s ESOP while management said the firm would retain a culture of employee ownership. Current ownership percentages were not disclosed in the 2026 pages reviewed. ^14,15,38

Heffernan Network Insurance Brokers is described as a wholly owned subsidiary, formerly OLI Insurance Services, that acquires or partners with independent agencies. Costero Brokers Ltd. appears as Heffernan’s London location listing. Heffernan Benefit Advisors is the name used on the employee-benefits page. These related names do not by themselves identify the producer or insurer on a California technology policy. ^34,35,24,16

At-Bay markets Tech E&O to technology businesses. Its current product page states primary and excess appetite up to $5 billion in revenue and $10 million in limits; the broker-platform route has lower published ceilings of $100 million in revenue and $3 million in limits. These are appetite ceilings, not guaranteed offers. ²

A September 2023 Tech E&O appetite PDF still accessible on At-Bay’s site has lower revenue and limit ceilings than the current product page and lists restricted classes including autonomous AI. It should not be treated as current eligibility guidance; ask underwriting for the applicable appetite version. ^12,2

Heffernan Insurance Brokers is an independent retail brokerage that arranges business insurance, personal insurance, employee benefits, and financial-services products. Its technology practice says it specializes in mid- to late-stage technology companies, including venture-funded startups, pre-IPO companies, and firms using enterprise risk or self-insurance strategies. A separate small-business division describes serving sole proprietors through fast-growing companies, including technology businesses. ^14,20,21,15

At-Bay Stance offers vulnerability monitoring, fraud defense, employee security training and access to cyber advisors. Access is tied to the policy’s Embedded Security Fee and Endorsement; optional managed detection and response (MDR) is a separate purchase from At-Bay Security, LLC. ⁷

At-Bay markets Stance MDR for endpoints and email, plus managed extended detection and response (MXDR) spanning endpoint, email, identity and cloud. It says MDR is optional for insurance and available beyond its policyholders. Coverage enhancements and premium credits have qualifying conditions. ⁷

At-Bay describes broker dashboard access to active policies and renewals, with rapid and manual renewal paths. Its platform page says rapid renewals bind automatically 15 days before expiry; buyers should confirm enrollment, terms and change deadlines with their broker. ⁶

Heffernan says clients get claims services, loss control, HR consulting, and risk-management support alongside insurance placement. Its modern-brokerage page describes digital access to documents, program details, and service-activity status, plus tools such as TrustLayer for insurance verification. These are company-described servicing features. ^19,36,23

At-Bay describes an in-house claims team that coordinates with a breach coach and response partners after a cyber incident. Its claims page provides incident reporting routes, and Response & Recovery is integrated with the claims process. This establishes a described support process, not claims payment or service quality. ^8,9

Heffernan describes full-service claims consulting from intake through resolution, including workers’ compensation strategy, carrier liaison, and experience-mod analysis; 24/7 medical triage; and advocacy on general liability, auto, and property claims, including litigation support. The marine-cargo program separately describes a claims division with authority to adjust, settle, and issue payments on that program. These statements document claimed assistance. They do not establish that a claim will be paid or that reported speed or savings figures are independently verified. ^23,29
