## Research Scope and Use

Use this comparison to evaluate Chubb and THREE by Berkshire Hathaway for Cyber Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Chubb’s cyber endorsements specify tailored limits or retentions for systemic events and ransomware, plus a 45-day patching grace period. THREE lists cyber liability in its package without published cyber-specific terms. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")

## What Is Chubb?

Chubb fits technology firms seeking DigiTech ERM or small businesses with up to $30 million in revenue seeking a BOP; buyers wanting an instant direct purchase should compare online carriers. Agents can quote eligible small accounts, with a faster cyber route. [1](https://www.chubb.com/us-en/business-insurance/industries/technology.html "Insurance For Technology Companies") [2](https://www.chubb.com/us-en/terms-of-use.html "Terms Of Use") [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

## What Is Cyber Insurance?

Cyber insurance can help pay covered response costs and claims against your business after a cyber incident. If your business relies on data, software or outside providers, compare response limits, vendor outages and approval rules. [8](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [9](https://www.aig.com/content/dam/aig/america-canada/us/documents/business/cyber/cyberedge-wording-sample-specimen-form.pdf "CyberEdge specimen policy")

## Key Differences in Cyber Insurance

### Coverage structure

Specific endorsements versus a package category

### Service and placement

Chubb names a Widespread Event Endorsement with separate limits and retentions for systemic events, a Ransomware Encounter Endorsement for tailored ransomware terms, and a 45-day patch grace period under its Neglected Software Exploit Endorsement. THREE lists cyber liability in its Business Owners Policy without public endorsement detail. Ask which Chubb endorsements fit your risks and what THREE’s form says about these events. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### Service and placement

Chubb gives agents and brokers Cyber Central for standalone quotes and Marketplace for bundled lines; its materials also describe a 24/7 response hotline and provider panel. THREE directs small businesses to an online package quote with licensed advisor support. Confirm which Chubb channel fits your business size and compare incident-response access with the THREE policy documents. [4](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance.html "Cyber Insurance for Businesses") [5](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway")

## What to Confirm in Cyber Insurance Quotes

- For Chubb, name the underwriting entity, quoted limits and retentions, and whether ransomware or widespread-event endorsements are included. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- For THREE, identify the cyber form, limits, event treatment, and incident-response hotline in the proposal. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

## Offering Details

| Criteria | Chubb Cyber Insurance (Cyber Enterprise Risk Management) | THREE Business Owners Policy |
| --- | --- | --- |
| Role in This Line | Chubb underwrites Cyber Enterprise Risk Management (Cyber ERM) directly. It covers cyber, privacy and media exposures for organizations of any size that handle sensitive data or run a network or website. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Cyber Insurance Coverage & Products page, Cyber Enterprise Risk Management section..) | THREE presents Cyber as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant..) |
| Issuing Insurer | The reviewed pages describe Chubb as the carrier but do not name the specific Chubb-group underwriting entity for cyber policies; the issued policy would name the entity. [4](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance.html "Cyber Insurance for Businesses") [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Not found in reviewed sources; scope: Both cyber pages as read on 2026-09-23..) | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy..) |
| Who It’s For | Chubb says there are no minimum premiums and premiums scale for all risk sizes, offers Cyber Central and Marketplace quoting for risks under $100 million in revenue, and a customizable large-account cyber risk management solution for organizations over $1 billion in revenue. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Cyber Insurance Coverage & Products page eligibility and quoting description..) | The reviewed product page does not state separate eligibility rules for Cyber; the general quote and advisor route is not proof that a particular business qualifies for it. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [5](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms..) |
| Coverage Features | Chubb lists first-party cyber incident response fund, business interruption (with contingent business interruption for outsourced technology providers), digital data recovery, and network extortion; third-party cyber/privacy/network security liability, payment card loss, regulatory proceedings and media liability; and cyber crime coverages (computer fraud, funds transfer fraud, social engineering fraud) available by endorsement. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Cyber insurance coverage list on the products page; subject to exclusions and the policy as issued..)<br><br>Chubb offers a Widespread Event Endorsement with separate limits and retentions for systemic cyber events, a Ransomware Encounter Endorsement that lets buyers tailor limits and retentions for ransomware losses, and a Neglected Software Exploit Endorsement that gives a 45-day grace period to patch published vulnerabilities before risk-sharing shifts toward the policyholder. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Innovative coverage concepts section; endorsement availability depends on underwriting..) | THREE's Business Owners Policy page lists Cyber Liability among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Official THREE package marketing for Cyber. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy..) |
| Limits and Retentions | The reviewed pages do not publish specific per-policy limit or retention amounts; Chubb says it can build large insurance tower programs with substantial primary limits for organizations over $1 billion in revenue but gives no figures. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Not found in reviewed sources; scope: Cyber Insurance Coverage & Products page as read on 2026-09-23..) | The reviewed public product page does not state a separate limit or deductible for Cyber; THREE says the quote-specific insurance summary lists limits and deductibles. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible..) |
| Risk Services | Chubb says cyber policyholders get access to a panel of pre-approved incident response providers, a 24/7 hotline and Cyber Alert app, a Cyber Threat Intelligence Team, a Vulnerability Management Outreach program, and the Chubb Cyber Index for trend and cost data. [4](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance.html "Cyber Insurance for Businesses") (Evidence: Company-reported; scope: Cyber Insurance for Businesses page, Cyber Services and Beyond Risk Transfer sections..) | Confirm in your quote. |
| How to Apply | Agents and brokers can quote cyber alone through Cyber Central or bundled with other lines through Chubb Marketplace; multinational programs can be serviced locally in more than 35 countries. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Cyber Insurance Coverage & Products page quoting section..) | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. [5](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the route for the overall THREE product. It does not show whether Cyber will be offered for a particular business or whether a customer can bind that line without an issued policy..) |
| Claims Support | Chubb reports 24/7 incident response availability by hotline or its Cyber Alert app, and publishes an annual Cyber Claims Landscape report analyzing claim frequency, severity and ransomware trends. [4](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance.html "Cyber Insurance for Businesses") (Evidence: Company-reported; scope: Cyber Insurance for Businesses page; claims scenarios and report are company-reported..) | Confirm in your quote. |
