Aon vs 
Gallagher: How Do They Compare for Cyber Insurance?
What Is Aon?
Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. 1,2
What Is Gallagher?
Gallagher’s technology specialists serve startups through global enterprises, while its executive-risk team supports IPO and M&A needs; small firms seeking one simple digital quote should compare online agencies. 4,5,6,7,8
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. 11,12
Key Differences in Cyber Insurance
Coverage categories and target buyers
Aon says cyber offerings vary by insurer and describes reviewing policy terms. Gallagher distinguishes first-party coverage when a business’s own systems or data are breached from third-party claims by customers, listing notification, credit monitoring, legal fees and regulatory fines as possible costs. Gallagher recommends cyber for businesses handling customer data or electronic payments, including retail, healthcare, finance and home repair. Buyers should verify each listed expense in the form and their quote. 3 9
Services by account segment
Aon describes claims advocacy and outside response-provider relationships with separate contracts. Gallagher says larger accounts can access eRiskHub and a dedicated claims team that includes cyber forensic accountants; its small-business page does not describe the same service. Buyers should ask which Gallagher segment will handle them before assigning value to those services. 3 10

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.[4][6][7]

Aon vs Gallagher: Cyber Insurance: documented features by provider
| Criteria | Aon Cyber brokerage and risk-advisory offering | Gallagher Cyber Liability Insurance |
|---|---|---|
| Role in This Line | Aon describes cyber insurance brokerage and risk-advisory services. It is not identified as the risk-bearing insurer, and the global page does not name the carrier for a particular placement. 3Company-reported. Aon’s official global product/capability page. The statement is limited to Aon’s marketing of brokerage or advisory services, not policy issuance. | 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. 9,10Company-reported. Small-business cyber product page and the group-level cyber liability page. |
| Issuing Insurer | The reviewed page does not identify the insurer or the legal producing entity for a specific placement. Ask Aon to identify both for the quoted risk. 3Not found in reviewed sources. Aon’s global product/capability page reviewed 2026-09-30; no buyer quote, binder or policy was reviewed. This does not establish that no insurer or producing entity is available. | Neither the small-business cyber page nor the group-level cyber liability page names the insurer that would issue a given client's policy. 9,10Not publicly disclosed. Checked both pages on 2026-09-23. |
| Who It’s For | Aon describes cyber services for organizations managing cyber risk. Its global practice page does not publish a complete industry, revenue, security-control or state-by-state eligibility schedule. 3Company-reported. Audience stated by Aon on its global capability page; this does not establish a specific applicant’s eligibility or placement availability by U.S. state. | 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. 9Company-reported. Small-business cyber product page "Who needs Cyber Liability Insurance" section; actual acceptance depends on underwriting. |
| Coverage Features | Aon describes cyber insurance as one part of cyber risk financing and says it reviews policy offerings because terms and conditions vary. For professional-services firms, it discusses coordinating cyber and professional-liability coverage. This is brokerage guidance and does not establish the terms of any cyber policy. 3Company-reported. Aon’s broker-authored explanation of the insurance line. It does not establish an individual insured’s policy entitlement; the insurer’s form, endorsements and declarations control. | 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. 9Company-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. 9Company-reported. Small-business cyber product page market-commentary section; a general market view, not a quote for any specific business. |
| Limits and Retentions | The reviewed page does not state a standard buyer-specific limit, retention or deductible for this placement. Confirm amounts, sublimits and conditions in the quote and issued policy. 3Not publicly disclosed. Aon’s global product/capability page reviewed 2026-09-30; no buyer quote or policy form was reviewed. | 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. 9,10Not publicly disclosed. Checked both pages on 2026-09-23. |
| Risk Services | Aon describes cyber claims advocacy and preparation and relationships with third-party incident-response providers. The retained official source notes that provider contracts are separate, no performance guarantee is made, and referral remuneration may occur; confirm the providers, scope and compensation applicable to a client. 3Company-reported. Company-reported brokerage and advisory services. Account-specific service terms are not stated. | 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. 10Company-reported. Group-level cyber liability page; not confirmed as included with the small-business product. |
