## Summary

Aon says cyber policy terms vary and describes brokerage review and claims advocacy. Berkshire Hathaway Specialty Insurance markets third-party breach liability, response and extortion costs, network-failure interruption, and both standalone and blended E&O/Cyber forms. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy")

## What Is Aon?

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.

## 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. [10](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [11](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

### Standalone and blended cyber placement

Aon describes cyber as part of risk financing and says its team reviews policy offerings because terms differ. Berkshire Hathaway Specialty Insurance offers a standalone Network Security & Privacy policy as well as blended E&O/Cyber forms in Professional First. Buyers choosing between them should consider whether cyber needs to sit alongside professional liability and then compare the actual limits, exclusions and shared terms in the proposed documents. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy")

### Incident expenses and risk resources

Aon describes claims preparation and advocacy, plus relationships with response providers under separate contracts. Berkshire Hathaway Specialty Insurance markets third-party breach exposures, direct response and extortion expenses, and interruption after network failure, and lists eRiskHub as a resource. Ask which response costs fall within the policy and whether the resource is included for your account; Aon’s page does not promise a standard insurer form. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy")

## What to Confirm in Cyber Insurance Quotes

- Ask BHSI which breach-response, extortion and network-interruption costs are insured, and request limits, waiting periods and sublimits. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy")
- Ask Aon who supplies response services and what contracts apply; ask BHSI whether eRiskHub access accompanies your quoted product. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy")

## Offering Details

| Criteria | Aon Cyber brokerage and risk-advisory offering | Professional First Network Security & Privacy |
| --- | --- | --- |
| 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..) | BHSI describes both a stand-alone Network Security & Privacy policy and blended E&O/Cyber forms in Professional First.

| 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. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Not found in reviewed sources; scope: 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..) | Confirm in your quote. |
| 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. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: 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..) | The Network Security & Privacy page names professional-services firms among its targets; the overview separately lists technology, telecom and financial-sector customers in targeted or selective categories.

| 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. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: 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..) | BHSI markets third-party breach exposures, direct breach-response and extortion expenses, and business interruption from a network-security failure. [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy") (Evidence: Company-reported; scope: The product page is a coverage summary; conditions, sublimits and exclusions require the policy and endorsements..) |
| 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. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Not publicly disclosed; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote or policy form was reviewed..) | Confirm in your quote. |
| 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. [3](https://www.aon.com/en/capabilities/cyber-resilience "Cyber Risk") (Evidence: Company-reported; scope: Company-reported brokerage and advisory services. Account-specific service terms are not stated..) | BHSI lists eRiskHub as a resource with its Network Security & Privacy product. [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/network-security-privacy-policy/ "Professional First Network Security & Privacy Policy") (Evidence: Company-reported; scope: The product-page listing does not define the resource’s service scope or confirm availability on an individual policy..) |

The public ratings for Berkshire Hathaway Specialty Insurance are low but thin: Trustpilot shows 2.1 out of 5 from 9 reviews and BBB shows 1 out of 5 from 6. Both mix travel and commercial customers, so we don't count them in a score.
