# At-Bay vs THREE

At-Bay’s surfaced offer centers on cyber, technology E&O and miscellaneous professional liability, with broker-platform quote, customization, binding and renewal tools.

## Before You Quote

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

## Highlights

At-Bay’s surfaced offer centers on cyber, technology E&O and miscellaneous professional liability, with broker-platform quote, customization, binding and renewal tools. THREE sells a broader packaged small-business policy issued by BHDIC. A technology buyer should compare the actual cyber and E&O grants, platform route and separate service charges with THREE’s scheduled package terms.

## At-Bay Reviews

Review Score: 9.5 / 10 from 2 rated sources, equally weighted.

At-Bay’s public review evidence is thin: one old G2 review and a BBB complaint record. It is not enough to judge day-to-day service or claims handling.

- BBB: BBB rating A (A+ to F). At-Bay identity; US commercial insurance review/satisfaction evidence sought on BBB. Period: accessed 2026-09-25. Checked 2026-09-25. [At-Bay | BBB Business Profile](https://www.bbb.org/us/ca/mountain-view/profile/insurance-companies/at-bay-1216-1000025767)
- G2: G2 star rating 4.5 (5 stars); 1 reviews. At-Bay company/product feedback; G2 seller profile identifies its offering as cybersecurity insurance and lists San Francisco headquarters. Not an insurance-policy claims or commercial-buyer satisfaction study. Period: review dated 2020-09-21. Checked 2026-09-25. [At-Bay seller profile and reviews](https://www.g2.com/es/sellers/at-bay)

## THREE by Berkshire Hathaway Reviews

Review Score: 7.3 / 10 from 2 rated sources, equally weighted.

The inspected sources report separate measures: NerdWallet’s 4.0/5 editorial rating is excluded from the source-rating average; Trustpilot displayed 2.5/5 from five user posts and BBB displayed 4.8/5 from 265 reviews. Trustpilot and BBB include different purchase, service and agent/intermediary interactions, not a verified common policyholder cohort. BBB separately lists complaints. Any source-rating average weights eligible platforms equally and is not a pooled, representative customer-experience estimate or a claims-quality measure.

- NerdWallet: NerdWallet editorial rating 4.0 (5 stars). NerdWallet editorial evaluation of THREE commercial insurance; updated May 11, 2026.

- BBB: BBB customer review average 4.8 (5 stars); 265 reviews. BBB profile for THREE by Berkshire Hathaway, customer-review and complaints pages directly rechecked 2026-09-29. The customer-review population includes sales-agent/intermediary interactions and customer purchase/service reports; it is not a verified uniform policyholder or claims-outcome cohort. Average and complaints are distinct populations. BBB says third-party information may not be verified and complaint text may be incomplete. Period: Displayed 2026-09-29. Checked 2026-09-29.

A listing may be arranged through an insurer or partner. “Not listed” means this catalogue has no separate offering recorded; ask the provider whether it can quote the coverage and request the policy terms.



## 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.

## Specialist Technology Products or a Business Package

At-Bay offers Tech E&O that it describes as combining professional liability and cyber protection for technology companies; its public material also describes cyber and miscellaneous professional liability products. THREE markets a business-owners package with multiple liability, property, auto, cyber and other categories. These labels do not prove the same insuring agreement or limit. A technology buyer should check whether the customer’s contract, service-credit exposure, privacy risk and system interruption fit the exact form and retentions quoted by each company. [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance") [23](https://threeinsurance.com/business-owners-policy "Business Owners Policy | THREE") [24](https://threeinsurance.com/benefits "Benefits | THREE") [15](https://threeinsurance.com/the-policy "The Policy")

## Broker Platform and Direct Quote Route

At-Bay describes a broker platform for quoting, customizing, binding and renewing cyber, Tech E&O and MPL policies. Its current Tech E&O page reports up to $5 billion in revenue and $10 million limits for primary and excess business, while the broker platform advertises a quick quote route and another platform-specific appetite. The provider record flags the product-page and platform ceilings as route-specific and not guaranteed offers; an older appetite guide also differs from the current product page. THREE sends small-business buyers to an online quote flow with advisor help. Ask which channel and appetite applies before relying on a ceiling or timing claim. [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") [4](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [12](https://www.at-bay.com/wp-content/uploads/2021/05/At-Bay-Tech-EO-Appetite-Guide-2022.pdf "At-Bay Surplus Tech E&O Appetite Guide") [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [14](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [16](https://threeinsurance.com/faqs "FAQs: Understanding THREE")

## Security and Claims Services

At-Bay says eligible Tech E&O policies include access to its Stance security platform; its separate security material describes optional managed detection and response products and an embedded security fee. The provider record also describes cyber incident reporting and an in-house claims team, without claiming claim payment or service quality. THREE describes phone or online claim reporting and an assigned account manager for questions and updates. Compare which security services are included, separately charged or subject to endorsement, and keep claim service claims distinct from policy response. [7](https://www.at-bay.com/stance/ "At-Bay Stance") [7](https://www.at-bay.com/stance/ "At-Bay Stance") [8](https://www.at-bay.com/claims/ "Claims Handling") [9](https://www.at-bay.com/security/response-recovery/ "Response & Recovery") [18](https://threeinsurance.com/claims "Filing a Claim: Call to get started") [16](https://threeinsurance.com/faqs "FAQs: Understanding THREE")

## What to Confirm in Quotes

Request the issuing insurer, policy form and actual eligibility for your business, state and requested limits. At-Bay’s reviewed product pages do not establish a current California issuer for every product, and its platform appetite differs by product route. THREE’s state-specific policy controls; its marketing list is not a coverage schedule. Add any Stance fee, endorsement or separate MDR charge to the requested total-cost comparison. [11](https://www.at-bay.com/press_releases/at-bay-begins-issuing-policies-on-its-own-paper/ "At-Bay Begins Issuing Policies on its own E&S Paper") [5](https://www.at-bay.com/licenses/ "Licenses") [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance") [4](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [7](https://www.at-bay.com/stance/ "At-Bay Stance") [15](https://threeinsurance.com/the-policy "The Policy")

What each provider documents about the services you may need.

| Criteria | At-Bay | THREE by Berkshire Hathaway |
| --- | --- | --- |
| Business role | At-Bay offers cyber, technology E&O and miscellaneous professional liability, with coverage described as underwritten by non-admitted insurers. At-Bay Insurance Services LLC is its disclosed property-and-casualty agency and surplus-lines broker. [1](https://www.at-bay.com/insurance/ "Cyber, Tech E&O & Professional Liability Insurance") [5](https://www.at-bay.com/licenses/ "Licenses") (Evidence: Company-reported; scope: US brand and disclosed producer; company statements, not regulatory verification.; verified: 2026-09-16.) | THREE is the commercial brand and product form used by Berkshire Hathaway Direct Insurance Company (BHDIC), which identifies itself as doing business as THREE and names itself as issuer on the sample THREE policy. THREE’s FAQ describes THREE or THREE Insurance as the product name, not a separate insurer. The state-specific issued policy controls. [14](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [15](https://threeinsurance.com/the-policy "The Policy") [16](https://threeinsurance.com/faqs "FAQs: Understanding THREE") (Evidence: Company-reported; scope: U.S. THREE commercial-insurance brand and sample policy; current company identity pages checked 2026-09-28. Company-reported legal disclosure; the state-specific issued policy controls the buyer’s contract.; verified: 2026-09-28.)<br><br>Berkshire Hathaway’s published company list identifies Berkshire Hathaway Direct Insurance Company (THREE) and lists Berkshire Hathaway Specialty Insurance (BHSI) and biBERK separately. Its 2025 annual report says BH Direct and GUARD together primarily offer commercial products to small and medium-sized businesses; it separately describes BH Direct’s admitted commercial underwriting and use of the biBERK.com and Threeinsurance.com distribution platforms. The reviewed list and report do not establish the exact direct-versus-indirect ownership chain. [21](https://www.berkshirehathaway.com/subs/sublinks.html "Links to Berkshire Hathaway Subsidiary Companies") [20](https://www.berkshirehathaway.com/2025ar/202510-k.pdf "Berkshire Hathaway Inc. 2025 Annual Report / Form 10-K") (Evidence: Company-reported; scope: Berkshire Hathaway company list checked 2026-09-28 and 2025 annual-report discussion of BH Direct and GUARD; group relationship and commercial operating scope only, not a precise ownership-chain finding.; verified: 2026-09-28.) |
| Customer focus | 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.)<br><br>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](https://www.at-bay.com/wp-content/uploads/2021/05/At-Bay-Tech-EO-Appetite-Guide-2022.pdf "At-Bay Surplus Tech E&O Appetite Guide") [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Legacy document has inconsistent autoquote revenue figures internally. Current HTML controls description of advertised ceilings, but current class eligibility remains unresolved.; verified: 2026-09-16.) | THREE describes its focus as businesses and presents industries it serves. Berkshire Hathaway’s 2025 annual report says BH Direct and GUARD together primarily offer commercial insurance to small and medium-sized businesses; it separately says BH Direct underwrites through the biBERK.com and Threeinsurance.com distribution platforms. Eligibility varies by state and business. [14](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [20](https://www.berkshirehathaway.com/2025ar/202510-k.pdf "Berkshire Hathaway Inc. 2025 Annual Report / Form 10-K") (Evidence: Company-reported; scope: THREE’s company-described business focus and industry examples, plus the 2025 report’s joint BH Direct-and-GUARD SMB statement. The report does not attribute that customer-size focus to BHDIC alone; actual eligibility varies by state and business.; verified: 2026-09-28.) |
| Application process | 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.) | THREE directs prospective customers to an online quote flow and says licensed Small Business Advisors can help them start or continue the process; the company’s FAQ also describes a phone quote and says an unfinished quote can be saved and resumed. This documents quote routes, not online purchase or binding by an individual customer. [14](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [16](https://threeinsurance.com/faqs "FAQs: Understanding THREE") (Evidence: Company-reported; scope: U.S. business insurance quote application. Company-described online and phone process; no customer form was submitted and no binding outcome was tested.; verified: 2026-09-28.)<br><br>THREE describes a partner-agency channel. Its partner page says the Agency Service Team assists policyholders and agents and that agency partners can use the THREE platform to quote, bind, and issue policies online. This describes the partner channel, not the direct public quote flow. [19](https://threeinsurance.com/become-a-three-partner "Become a THREE Partner") (Evidence: Company-reported; scope: THREE partner agency program and platform capabilities as described by the company; these capabilities apply to partner agencies and do not establish direct-customer self-binding.; verified: 2026-09-28.) |
| Servicing and renewals | 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.)<br><br>You can buy optional MDR for endpoint and email protection, or MXDR for endpoint, email, identity and cloud; At-Bay says these can be bought beyond policyholders too. Confirm service eligibility and any conditional coverage enhancements or premium credits. [7](https://www.at-bay.com/stance/ "At-Bay Stance") (Evidence: Company-reported; scope: Security services, not additional insurance coverage lines; comparable approved solutions may also qualify.; verified: 2026-09-16.)<br><br>Avoid an unwanted automatic renewal by confirming your dashboard route and deadlines: At-Bay describes rapid and manual renewals, and says rapid renewals bind automatically 15 days before expiry. [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") (Evidence: Company-reported; scope: Company-described workflow; no promise of unchanged renewal price or terms.; verified: 2026-09-16.) | THREE says policyholders can submit policy-change requests through My THREE Online or contact a Small Business Advisor. Its FAQ lists account/contact and billing tasks, vehicle and location changes, and certificate requests; it says vehicle and location requests are reviewed and processed by its team. The page does not establish automatic approval or effective dates for changes. [16](https://threeinsurance.com/faqs "FAQs: Understanding THREE") (Evidence: Company-reported; scope: Company-described servicing routes and request types for THREE policyholders; submitted requests may be reviewed and processed, and approval/effective dates are not established.; verified: 2026-09-28.)<br><br>THREE describes its policy as a one-year term. Its payment terms say automatic bank-draft authorization renews if the customer renews the policy; they do not say that the policy itself renews automatically or explain the complete renewal-offer process. [16](https://threeinsurance.com/faqs "FAQs: Understanding THREE") [17](https://threeinsurance.com/terms-conditions "Terms & Conditions") (Evidence: Company-reported; scope: Published FAQ and payment terms reviewed 2026-09-28.
