# At-Bay vs Berkshire Hathaway Specialty Insurance

At-Bay combines technology E&O and cyber exposures and describes conditional Stance services; BHSI’s Professional First catalogue lists standalone Cyber and blended E&O/Cyber forms, while account terms remain proposal-specific.

## Before You Quote

Ask each provider about eligibility, the issuing insurer, policy wording, limits, retentions, exclusions and costs for your business.

## Highlights

At-Bay markets technology E&O combining professional and cyber exposures, with Stance services subject to eligibility, endorsement and fees. BHSI’s U.S. Professional First overview lists standalone Cyber and blended E&O/Cyber forms, alongside Technology E&O; that catalogue does not establish an account’s eligibility or terms. A technology buyer should compare the proposed forms and limits and separate At-Bay’s conditional Stance and MDR costs from the policy premium. At-Bay’s public pages conflict on revenue and limit ceilings, so those figures need written confirmation.

Canonical evidence gaps: The AM Best rating carries a group-affiliation code, so it reflects the Berkshire Hathaway group rather than a standalone view.; No NAIC complaint index or state complaint data for BHSIC was found, so service outcomes are not measured.; Which BHSI-branded product is written on BHSIC paper versus an affiliate (Direct, Homestate, travel programs) is not mapped by product.; A state-by-state license lookup was not run; the all-states statement comes from the Nebraska exam report.; Non-U.S. regulators (FCA and PRA for the U.K. entity, Singapore, Australia and others) were not searched.).

## Berkshire Hathaway Specialty Insurance Reviews

Review Score: not enough ratings.

The public ratings for Berkshire Hathaway Specialty Insurance are low but thin: Trustpilot shows 2.1 out of 5 from 9 reviews and BBB shows 1 out of 5 from 6. Both mix travel and commercial customers, so we don't count them in a score.

- Trustpilot: TrustScore 2.1 (out of 5); 9 reviews. Trustpilot profile for bhspecialty.com, accessed 2026-09-29.

## Introduction

At-Bay publishes technology E&O combining professional-liability and cyber exposures, with eligibility, endorsement and fee conditions for Stance services. BHSI’s U.S. Professional First overview names standalone Cyber and blended E&O/Cyber forms, including Technology E&O; this is marketed product scope, not an account-specific offer or policy wording. BHSI’s website submissions are nonbinding, and only contracted National Indemnity group agents with state authority may bind. At-Bay’s public pages conflict on revenue and limit ceilings, so confirm those in a current quote.

## Optional Spot Service Handoff

Spot can help prepare applications, coordinate brokers, and compare proposals. If that work is needed, collect the company's task, known deadline, current broker, and open questions for a [free consultation](https://spot.insure/pricing.md). The company decides what to buy; Spot does not automatically bind coverage.

## Key Differences Between At-Bay and Berkshire Hathaway Specialty Insurance

### Technology E&O and cyber scope

At-Bay’s published Tech E&O description combines professional liability and cyber exposures, including coding or implementation errors and customer contractual indemnity, subject to policy wording. BHSI’s U.S. Professional First overview describes standalone Cyber and blended E&O/Cyber forms and names Technology E&O, Media Liability and Network Security & Privacy. This establishes marketed product scope, not this account’s terms or eligibility; compare the proposed insuring agreements, limits, exclusions and issuer with At-Bay’s named product. [31](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")

Technology companies can compare one Tech E&O product for professional and cyber exposures, including coding errors, failed implementations and customer contractual indemnity; service-credit damages remain subject to policy terms. [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product highlights, not an issued policy or universal contract coverage.; verified: 2026-09-16.)



BHSI’s U.S. At A Glance section (version 2026-8-03 A) lists commercial property, casualty, healthcare professional liability, executive and professional lines, surety, travel, programs, employer stop loss, and homeowners insurance. The guide is informational, not policy coverage, and its brand-level list does not identify the insurer on a particular policy. [14](https://www.bhspecialty.com/wp-content/uploads/marketing/Interactive-AAG.pdf "At A Glance") [15](https://www.bhspecialty.com/about-us/ "About Us") [18](https://www.bhspecialty.com/terms-conditions/ "Terms of Service") (Evidence: Company-reported; scope: A description of BHSI's U.S. line list in its U.S. At A Glance section (version 2026-8-03 A) only. The guide says its descriptions are informational and are not coverage; its brand-level list does not assign an issuing insurer to a particular product or policy. This is not a claim that one legal insurer issues every BHSI product.; verified: 2026-09-29.)

[31](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")

### Security services and total cost

At-Bay says eligible policies may include Stance monitoring, fraud defense, training and cyber-advisor access, subject to an endorsement and Embedded Security Fee; managed detection and response is separately purchased. BHSI’s Network Security & Privacy page says policyholders have access to eRiskHub for cyber-exposure education and breach-response planning. That is not evidence of services equivalent to At-Bay’s Stance monitoring or separately purchased MDR; confirm the included services and conditions in each proposal. [36](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy")

Eligible policies may include Stance monitoring, fraud defense, employee training and cyber-advisor access, but the Embedded Security Fee and endorsement apply; MDR is a separate purchase from At-Bay Security, LLC. [7](https://www.at-bay.com/stance/ "At-Bay Stance") (Evidence: Company-reported; scope: Current service descriptions and footnotes; no claims of effectiveness or independent testing.; verified: 2026-09-16.)



Add security charges separately when comparing total cost: Stance has an Embedded Security Fee and endorsement, while MDR is purchased separately from premium and broker charges. [7](https://www.at-bay.com/stance/ "At-Bay Stance") (Evidence: Company-reported; scope: Does not describe included security as free or quote an unverified fee amount.; verified: 2026-09-16.)

[14](https://www.bhspecialty.com/wp-content/uploads/marketing/Interactive-AAG.pdf "At A Glance")

### Audience and binding path

At-Bay publishes a technology-oriented product and an online broker platform, but an online quote remains subject to application review, conditions and binding steps. BHSI’s online submission is also nonbinding; its terms identify contracted National Indemnity group agents as the parties who may bind, issue or change coverage, subject to state authority. Compare the named intermediary, underwriter review, required documents and effective-date confirmation instead of treating either web route as immediate coverage.

Large technology companies may fit At-Bay’s published Tech E&O appetite, but the quote route matters: its product page lists up to $5 billion revenue and $10 million limits, while its broker platform lists $100 million and $3 million. These are ceilings, not guaranteed offers. [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Current product-page appetite; no inference of pre-revenue, industry-specific or California eligibility.; verified: 2026-09-16.)



An online quote is not bound coverage; At-Bay’s broker process still requires application review, chosen limits and retentions, documents, effective date, contingencies and signatures before binding. [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") [4](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Public broker workflow; no application submitted and no speed guarantee inferred.; verified: 2026-09-16.)



BHSI's website terms say online application or quote submissions are informational and nonbinding; only contracted agents of the National Indemnity group may bind coverage, issue policies or certificates, or change coverage. Group companies' authority also varies by state, so the terms do not show that every application must begin through an agent. [18](https://www.bhspecialty.com/terms-conditions/ "Terms of Service") (Evidence: Company-reported; scope: The website's own online submissions and binding authority described by BHSI's terms; not a statement about every product's intake process or a claim that purchase can be completed online.; verified: 2026-09-28.)

## What to Confirm in Quotes

- Ask whether At-Bay’s current Tech E&O proposal includes cyber, which limits are shared, and how indemnities, service credits, retroactive dates and reporting provisions apply. Its public product page and broker platform differ on revenue and limit ceilings; rely on the written account-specific terms. [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [6](https://www.at-bay.com/brokers/platform/ "Broker Platform")
- Request the Stance endorsement, Embedded Security Fee, included services and any separate MDR agreement; compare those costs with your existing security provider. [7](https://www.at-bay.com/stance/ "At-Bay Stance")
- Ask BHSI which standalone Cyber or blended E&O/Cyber form is proposed, whether the account is eligible, what limits and exclusions apply, which insurer would issue it, and which authorized agent can bind it. The catalogue does not settle those account-specific points. [31](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview") [18](https://www.bhspecialty.com/terms-conditions/ "Terms of Service")
