# At-Bay vs CNA

At-Bay describes broker quoting with underwriting and security-service conditions; CNA directs small-business buyers to agents and publishes claims-entry options.

## Before You Quote

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

## Highlights

At-Bay describes a broker-led online quote process that still requires underwriting review and completed binding steps, plus policy-linked security services with stated fees and conditions. CNA directs small-business buyers to an agent and provides a Claims Center entry point. For cyber exposure, compare the actual policy, included services, separate security purchases and claim-notice 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)

## CNA Reviews

Review Score: 9.0 / 10 from 1 rated source, equally weighted.

Customer feedback on CNA is mixed and hard to compare. NerdWallet gave it 4.5 out of 5 for manufacturers, while Trustpilot shows about 1.4 out of 5 from 49 mostly self-selected reviews.

## Introduction

If cyber protection is the goal, compare the policy and incident services separately. At-Bay describes an online broker quote route with application review and binding conditions, and cyber services tied to endorsements and fees. CNA's published small-business route points buyers to an agent; the checked material does not establish a matching cyber quote flow or security-service package. Ask for the exact form and each included or optional service before treating either proposal as comparable.

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.

## Quote Is Not Bound Coverage

At-Bay says the broker process continues after the online quote: the application, selected limits and retentions, documents, effective date, contingencies and signatures must be addressed before binding. CNA's page directs small-business buyers to an agent and ready-to-quote agents to CNA Central, but does not set out binding steps for every product. Ask the intermediary to identify outstanding requirements and the written effective date. [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") [4](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [16](https://www.cna.com/solutions/small-business "Insurance for Small Businesses")

## Security Services and Renewals

At-Bay describes Stance monitoring, fraud defense, training and cyber-advisor access for eligible policies subject to an endorsement and Embedded Security Fee. MDR or MXDR may be a separate purchase from At-Bay Security, LLC; these services are not additional insurance coverage lines. At-Bay also says rapid renewals bind automatically 15 days before expiry, while manual renewal is available. CNA documents agent access to policy documents and loss runs; its 2022 guide provides dated agent-facing billing and renewal-document details. Compare service eligibility, added charges and renewal controls on the actual proposal. [7](https://www.at-bay.com/stance/ "At-Bay Stance") [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") [16](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [18](https://www.cna.com/sites/default/files/assets/28007e1c-9e6b-4606-8060-670a9fb4b465/2589-SB%2BSmall%2BBusiness%2BCNA%2BCentral%2Bguide_2022.pdf?fid= "Small Business | CNA Central Agent Guide")

## Cyber Claim Response

At-Bay describes an in-house cyber claims team, breach coach, response partners and incident-reporting routes. That describes its cyber process, not payment or service quality, and non-cyber E&O notice terms may differ. CNA's Claims Center points visitors to reporting options and lists weekday phone help. Read the policy's notice and consent requirements before an incident, including instructions for engaging response vendors. [8](https://www.at-bay.com/claims/ "Claims Handling") [9](https://www.at-bay.com/security/response-recovery/ "Response & Recovery") [20](https://www.cna.com/claims-center "Report an Insurance Claim")

## What to Confirm in Quotes

- Which At-Bay services are included under the endorsement and fee, and which MDR/MXDR items require a separate purchase?
- Does the proposed renewal bind automatically, and what action and deadline can stop it?
- Which CNA agent and policy form address your cyber exposure, and what services or response vendors are included?
- Compare insurer, forms, incident-notice deadlines, consent terms, limits, exclusions, retentions and state availability.

## Compare Services

What each provider documents about the services you may need.

| Criteria | At-Bay | CNA |
| --- | --- | --- |
| 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.) | CNA directs small-business buyers to work with an agent. CNA also says its U.S. offices work with independent agents and brokers to provide policyholder service and insurance solutions. [16](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [17](https://www.cna.com/about/locations/us "United States") (Evidence: Company-reported; scope: CNA’s stated U.S. small-business route and U.S. agency relationships. These sources do not establish that every CNA product requires an agent or that buyers can complete a purchase directly online.; 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.

[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.) | CNA says CNA Central gives small-business agents access to policy documents, loss runs, and claims information. CNA’s 2022 agent guide says agents can access policy, billing, and claims information and download new-business, renewal, and endorsement documents. This describes agent access, not automatic renewal or a guaranteed renewal offer. [16](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [18](https://www.cna.com/sites/default/files/assets/28007e1c-9e6b-4606-8060-670a9fb4b465/2589-SB%2BSmall%2BBusiness%2BCNA%2BCentral%2Bguide_2022.pdf?fid= "Small Business | CNA Central Agent Guide") (Evidence: Company-reported; scope: Small-business agent servicing through CNA Central, based on the current U.S. small-business page and a guide copyrighted 2022.

It states weekday hours of 7 a.m.–7 p.m. Central Time and says the agency/customer relationship remains in place. This describes a particular service-center program, not every CNA account. [19](https://www.cna.com/system/files/agentcenter/a7ed16c6-bcc4-4673-836c-7461d77b585a/2510-SB-ss-Small-Business-Service-Center-v2%2B%25281%2529.pdf "Small Business Service Center") (Evidence: Company-reported; scope: Company-reported service-center functions from a 2021 CNA handout. The handout describes enrollment and account selection for this small-business agency program; it does not establish availability for every CNA policy or account.; verified: 2026-09-28.) |
| Claims assistance | After a cyber incident, At-Bay describes an in-house claims team, breach coach, response partners and incident-reporting routes; this documents its stated process, not claim payment or service quality.

The page does not establish complete online filing or claim outcomes. [20](https://www.cna.com/claims-center "Report an Insurance Claim") (Evidence: Company-reported; scope: CNA U.S. Claims Center page accessed 2026-09-28; policy-specific reporting instructions, completion of a claim online, and claim outcomes are not established by this page.; verified: 2026-09-28.) |
