## 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")

[4](https://www.markel.com/about-us "About us") [5](https://www.sec.gov/Archives/edgar/data/1096343/000109634326000020/mkl-20251231.htm "Markel Group Inc. 2025 Form 10-K")

## 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. [7](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [8](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

### Cyber 360 coverage menu and underwriting focus

Aon says cyber insurance is part of risk financing and reviews policies because terms and conditions vary. Markel Insurance lists Cyber 360 options including business and dependent interruption, eCrime, privacy and security liability, PCI liability, media liability and technology professional liability. Markel identifies businesses with strong security controls in financial, professional, retail, manufacturing, technology and healthcare sectors as its target audience. Buyers should verify which options and industries fit the actual policy and jurisdiction. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [6](https://www.markel.com/us/commercial/professional-and-management-liability/cyber "Cyber Insurance Coverage")

### Broker review and quote contact

Aon describes claims preparation and advocacy with outside incident-response providers under separate contracts. Markel Insurance invites prospective buyers or brokers to contact Markel or its underwriting team; that invitation does not establish a quote or binding timeline. A buyer can use Aon to compare carrier terms or contact Markel’s team directly, then ask how claims support, limits and exclusions work in the selected form. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [6](https://www.markel.com/us/commercial/professional-and-management-liability/cyber "Cyber Insurance Coverage")

## What to Confirm in Cyber Insurance Quotes

- Ask Markel which Cyber 360 options are included and whether interruption, dependent interruption, eCrime and professional liability share limits. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [6](https://www.markel.com/us/commercial/professional-and-management-liability/cyber "Cyber Insurance Coverage")
- Ask Aon about response-provider contracts; ask Markel to confirm security-control requirements, jurisdiction, insurer and quote steps. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [6](https://www.markel.com/us/commercial/professional-and-management-liability/cyber "Cyber Insurance Coverage")
