Chubb vs Gallagher Cyber Insurance

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. ³Company-reported. Cyber Insurance Coverage & Products page, Cyber Enterprise Risk Management section.

Gallagher Small Business arranges cyber liability coverage with outside carriers for small businesses; Gallagher's group-level practice separately places cyber coverage with its own risk-consulting services for larger accounts. Gallagher does not underwrite either policy. ^10,11Company-reported. Small-business cyber product page and the group-level cyber liability page.

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. ^4,3Not found in reviewed sources. Both cyber pages as read on 2026-09-23.

Neither the small-business cyber page nor the group-level cyber liability page names the insurer that would issue a given client's policy. ^10,11Not publicly disclosed. Checked both pages on 2026-09-23.

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. ³Company-reported. Cyber Insurance Coverage & Products page eligibility and quoting description.

Gallagher recommends this coverage for small businesses that handle customer data or accept credit card or electronic-funds-transfer payments, and specifically names retail, healthcare, financial services and home-repair businesses as frequent attack targets. ¹⁰Company-reported. Small-business cyber product page "Who needs Cyber Liability Insurance" section; actual acceptance depends on underwriting.

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. ³Company-reported. Cyber insurance coverage list on the products page; subject to exclusions and the policy as issued.

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. ³Company-reported. Innovative coverage concepts section; endorsement availability depends on underwriting.

Gallagher describes two components of cyber coverage: first-party coverage for when a business's own technology or data is breached, and third-party coverage for when a customer sues the business for failing to prevent a breach. It says the policy can cover customer notification, credit monitoring, legal fees and regulatory fines. ¹⁰Company-reported. Small-business cyber product page; a coverage description, not a specific policy's insuring agreement or exclusions.

Gallagher's small-business team says cyber insurance rates are flat to down due to competitive market forces despite high-profile losses, and flags generative-AI-driven risks such as more convincing phishing, social-engineering and deepfake attacks as an emerging concern. ¹⁰Company-reported. Small-business cyber product page market-commentary section; a general market view, not a quote for any specific business.

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. ³Not found in reviewed sources. Cyber Insurance Coverage & Products page as read on 2026-09-23.

Neither page publishes specific cyber coverage limits, retentions or premium ranges; the small-business page's $60 million claim example is an illustrative scenario, not a stated policy limit. ^10,11Not publicly disclosed. Checked both pages on 2026-09-23.

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. ⁴Company-reported. Cyber Insurance for Businesses page, Cyber Services and Beyond Risk Transfer sections.

For larger accounts, Gallagher's group-level cyber practice gives clients access to the Gallagher eRiskHub risk-management portal and a dedicated claims team that includes cyber forensic accountants; the small-business product page does not describe an equivalent service for that segment. ¹¹Company-reported. Group-level cyber liability page; not confirmed as included with the small-business product.
