Aon compares varying cyber policy terms and discusses coordinating professional liability; Chubb offers direct underwriting with endorsements for systemic events, ransomware and unpatched software.

## Research Scope and Use

Use this comparison to evaluate Aon and Chubb 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

Aon describes brokerage review of varying cyber terms and coordination with professional liability. Chubb directly underwrites Cyber ERM and offers endorsements for widespread events, ransomware limits and a 45-day vulnerability-patching grace period. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

## 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](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

[Aon profile](https://spot.insure/insurance-providers/aon)

## 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. [4](https://www.chubb.com/us-en/business-insurance/industries/technology.html "Insurance For Technology Companies") [5](https://www.chubb.com/us-en/terms-of-use.html "Terms Of Use") [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

[Chubb profile](https://spot.insure/insurance-providers/chubb)

## 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

### Policy tailoring and defined endorsements

Aon says cyber policy wording varies and describes reviewing options, including coordination with professional liability for professional-services firms. Chubb directly underwrites Cyber ERM and offers a Widespread Event endorsement with separate limits and retentions, a ransomware endorsement to tailor limits and retentions, and a 45-day patch grace period for specified vulnerabilities. Buyers should assess these named terms against their accumulation, ransomware and patch-management concerns. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### Incident support and access

Aon describes claims advocacy and third-party response relationships, with provider contracts separate. Chubb provides access to approved incident-response providers, a 24-hour hotline and Cyber Alert app, plus threat intelligence and vulnerability outreach. Chubb brokers can quote through Cyber Central or Marketplace depending on the risk. Ask whether the response panel and quoting route match your locations and account size. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [7](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance.html "Cyber Insurance for Businesses")

## What to Confirm in Cyber Insurance Quotes

- Ask Chubb which endorsements, retentions and patching conditions appear in your quote, and whether the 45-day period applies to your systems. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Ask Aon who contracts with response providers; ask Chubb for the insurer entity, hotline procedure and access requirements. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [6](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

## Offering Details

| Criteria | Aon Cyber brokerage and risk-advisory offering | Chubb Cyber Insurance (Cyber Enterprise Risk Management) |
| --- | --- | --- |
| 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. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: Aon’s official global product/capability page. The statement is limited to Aon’s marketing of brokerage or advisory services, not policy issuance..) | 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. [6](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..) |

This does not establish that no insurer or producing entity is available..) | 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.

| Coverage Features | Aon describes cyber insurance as one part of cyber risk financing and says it reviews policy offerings because terms and conditions vary.

[3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: Aon’s broker-authored explanation of the insurance line.

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.
