## 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.

- 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.

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.

## Key Differences Between At-Bay and Liberty Mutual

### Roles, Coverage and Buyer Fit

At-Bay’s broker submission still needs application review, selected limits and retentions, documents and signatures before binding. Liberty Mutual provides small-business quote and agent-finder routes and directs commercial buyers to agents or brokers. Neither entry point establishes online binding. [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") [27](https://www.libertymutual.com/small-business "Small Business Insurance Coverage") [16](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [7](https://www.at-bay.com/stance/ "At-Bay Stance")

Liberty Mutual describes online account tasks for small-business billing, certificates, premium audits and claim-status checks. At-Bay describes security and incident-response services for eligible policies; Stance includes a fee and managed detection is separate. Ask which functions and charges apply to the proposed policy. [27](https://www.libertymutual.com/small-business "Small Business Insurance Coverage") [7](https://www.at-bay.com/stance/ "At-Bay Stance") [8](https://www.at-bay.com/claims/ "Claims Handling")

At-Bay identifies a broker entity; its older carrier announcement does not establish today’s issuer for each product or state. Liberty Mutual says its issuing insurer is identified when a product is offered. Both reviewed commercial pages leave buyer-specific placement charges unknown. [5](https://www.at-bay.com/licenses/ "Licenses") [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") [16](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [28](https://business.libertymutual.com/contact-us/ "Contact Us")

## What to Confirm in Quotes

Ask At-Bay which insurer and state-specific form apply, whether Stance fees or separate managed-detection charges are included, and what service triggers incident response. [1](https://www.at-bay.com/insurance/ "Cyber, Tech E&O & Professional Liability Insurance") [7](https://www.at-bay.com/stance/ "At-Bay Stance") Ask Liberty Mutual whether the small-business account uses a BOP or separate commercial products, which entity issues each policy, and which account and claim tasks are available online. [31](https://www.libertymutual.com/small-business/business-owners-insurance "Business owner's policy insurance") [16](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [27](https://www.libertymutual.com/small-business "Small Business Insurance Coverage") Compare the current forms and total charges.

## Compare Services

What each provider documents about the services you may need.

| Criteria | At-Bay | Liberty Mutual |
| --- | --- | --- |
| 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.) | Liberty Mutual is a group brand spanning multiple insurance entities. Its business-site disclosure says coverage may be underwritten by Liberty Mutual Insurance Company or affiliates/subsidiaries and that the issuing insurer is identified when a product is offered; some policies may use surplus-lines insurers. The LMIC statutory statement identifies Comparion as a separate producer for LMIC policies it places. [16](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [29](https://www.libertymutualgroup.com/about-lm/investor-relations/documents/lmic.pdf-0 "Liberty Mutual Insurance Company 2025 Statutory Statement") (Evidence: Company-reported; scope: US commercial brand and channel overview. Does not assign LMIC or Comparion to every product; confirm the named insurer and producer on each offer and policy.; verified: 2026-09-29.) |
| 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.) | Liberty Mutual describes US Retail Markets as serving individuals and small businesses with personal and small-commercial property and casualty insurance countrywide, and Global Risk Solutions as providing commercial, specialty, reinsurance, and surety solutions to mid-size and large businesses worldwide. [15](https://www.libertymutualgroup.com/about-lm/investor-relations/our-company/company-profile "Company Profile") (Evidence: Company-reported; scope: Company-reported business-unit positioning; it does not establish that each product is available in every state or country.; verified: 2026-09-29.) |
| Coverage lines | 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.)<br><br>At-Bay’s cyber policy may address business interruption, system failure, extortion, privacy liability and financial fraud such as social engineering or invoice manipulation; your quote and policy set the actual limits and conditions. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance") (Evidence: Company-reported; scope: Current cyber product offering; components are not separate catalogue products.; verified: 2026-09-16.)<br><br>Businesses needing miscellaneous professional liability can ask At-Bay about primary coverage with limits up to $5 million and a tailored definition of professional services; state restrictions apply, and the product is claims-made-and-reported with a duty to defend. [4](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current MPL page; eligibility and policy wording remain underwriting-specific.; verified: 2026-09-16.)<br><br>If you need limits above primary Cyber or Tech E&O, At-Bay lists excess options for those lines; this does not establish a general commercial umbrella policy. [3](https://www.at-bay.com/insurance/cyber/ "Cyber Insurance") [2](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Shared umbrella-excess key used only for explicitly marketed excess products.; verified: 2026-09-16.) | Liberty Mutual publicly markets the listed commercial lines and packages in this record. Its small-business BOP combines property and general liability and can be supplemented with cyber and professional liability; the company describes commercial auto, workers compensation, and inland marine as separate from a BOP. ProShield packages management-liability components, and healthcare, professional-services, wholesale, and multinational pages describe specialized or industry-specific solutions. Line membership records actual company marketing, not a promise of availability, standalone issuance, a shared insurer, or uniform terms. [16](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [20](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") [21](https://business.libertymutual.com/commercial-solutions/property/ "Property") [24](https://business.libertymutual.com/commercial-solutions/surety/commercial-bonds/ "Commercial Bonds") [25](https://business.libertymutual.com/commercial-solutions/multinational/ "Multinational") [26](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution") [30](https://business.libertymutual.com/commercial-solutions/general-liability/ "General liability") [31](https://www.libertymutual.com/small-business/business-owners-insurance "Business owner's policy insurance") [32](https://business.libertymutual.com/commercial-solutions/professional-liability/ "Professional liability") [33](https://business.libertymutual.com/commercial-solutions/umbrella-and-excess-liability/ "Umbrella and excess liability") [34](https://business.libertymutual.com/industries/professional-services/ "Professional services") [35](https://business.libertymutual.com/commercial-solutions/healthcare-liability/ "Healthcare liability") [36](https://business.libertymutual.com/commercial-solutions/workers-compensation/ "Workers compensation") (Evidence: Company-reported; scope: Current official US commercial and small-business pages inspected September 29, 2026. Coverage-line membership is distinct from whether a detailed offering payload has enough supported claim detail for line comparisons. Package, sector and multinational-only scope stays attached to the member line.; verified: 2026-09-29.) |
| 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.) | Liberty Mutual's small-business page offers quote and agent-finder entry points. Its commercial pages direct business buyers to a broker or agent. A quote link does not establish online purchase or policy binding. [27](https://www.libertymutual.com/small-business "Small Business Insurance Coverage") [16](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [18](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance") (Evidence: Company-reported; scope: Public company pages only; no application was submitted and no authenticated workflow was inspected.; verified: 2026-09-29.) |
| 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.) | Liberty Mutual describes online account tasks for small-business customers, including billing, certificates, premium audits and claim-status checks. Access and available tasks may depend on the policy and account; a certificate does not amend coverage. [27](https://www.libertymutual.com/small-business "Small Business Insurance Coverage") [28](https://business.libertymutual.com/contact-us/ "Contact Us") (Evidence: Company-reported; scope: Company-described small-business account features; not an independent service-quality measure or guarantee.; verified: 2026-09-29.)<br><br>NerdWallet reports that Liberty Mutual’s commercial-property complaints were higher than expected for its market share and general-liability complaints were far higher than expected during 2022–2024. This is an attributed secondary analysis; its underlying counts and insurer-entity mapping were not independently recalculated here. [37](https://www.nerdwallet.com/business/insurance/learn/liberty-mutual-business-insurance "Liberty Mutual Business Insurance Review 2026: Big Company Dogged by Customer Complaints") (Evidence: Verified; scope: NerdWallet’s June 3, 2026 secondary analysis of commercial-property and general-liability complaints for 2022–2024. This does not identify an exact underwriting entity or constitute an independently reproduced regulator metric.; verified: 2026-09-29.) |
| Fees and compensation | 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.)<br><br>Ask for the full price and compensation disclosure because reviewed At-Bay pages do not publish commission rates, broker arrangements or complete placement fees; this gap does not mean those charges are absent. [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") [10](https://www.at-bay.com/terms-of-service/ "Terms of Service") (Evidence: Not publicly disclosed; scope: Scoped review of listed public pages on September 16, 2026; not a site-wide or contractual finding.; verified: 2026-09-16.) | No product-specific commission, broker fee, or customer fee schedule was verified in the official commercial pages reviewed. Compensation for a buyer's placement is unknown; do not infer that fees or commissions are absent. [16](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [28](https://business.libertymutual.com/contact-us/ "Contact Us") (Evidence: Not publicly disclosed; scope: Only public pages listed in this candidate were reviewed; statutory aggregate liabilities do not establish transaction-specific compensation.; verified: 2026-09-29.) |
