[3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") [8](https://www.cna.com/sites/default/files/assets/epack-3-cyber-media-technology-professional-liability-ss.pdf?ContentCache=NONE&MOD=AJPERES "Epack 3 – Cyber, Media, Technology & Professional Liability")

## 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")

## What Is Professional Errors and Omissions (E&O) Insurance?

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [9](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [10](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [11](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [12](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### Form and Coverage Scope

Aon describes professional liability as coverage tailored to a professional-services firm’s needs, without naming a product form. CNA offers Epack 3, which combines technology and professional liability with cyber and media in a modular policy, and EPS Plus, combining E&O and cyber for professional-services firms. CNA also identifies miscellaneous professional liability for non-licensed classes such as consultants, staffing firms, advertising agencies and event planners. Ask which CNA product aligns with your services. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")

### Buyer Fit and Policy Terms

CNA describes dedicated claims and risk-control support for its cyber, media, technology and professional-liability business. Aon describes advisors using data and industry knowledge for risk decisions, but does not specify claims support in the reviewed record. Neither public summary establishes the quote’s limits or exclusions. Compare CNA’s product selection with Aon’s proposed forms and confirm whether media and cyber share limits with E&O. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask CNA whether Epack 3 or EPS Plus fits your profession and whether limits are shared across lines. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")
- Ask Aon to identify claims support and whether E&O is standalone or bundled with cyber. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")

Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page.

| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement..) | Confirm in your quote. |
| Who It’s For | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice.

[3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) | CNA says its Miscellaneous Professional Liability targets non-licensed professional classes such as consultants, staffing firms, advertising agencies and event planners.

| Coverage Features | Aon describes professional liability as addressing professional-services firms’ liability exposure and says it tailors coverage structures to a firm’s needs. It identifies E&O as a commonly used name for professional-liability insurance; actual policy terms are not stated. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage..) | CNA markets Technology E&O for technology businesses facing professional-liability exposures and says it is intended to support contractual requirements. [7](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") (Evidence: Company-reported; scope: The page is a summary and does not define covered services, contract exceptions or policy triggers..) |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) | Confirm in your quote. |
| Risk Services | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) | CNA describes dedicated claims and risk-control support for its cyber, media, technology and professional-liability business. [7](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") (Evidence: Company-reported; scope: This portfolio-level statement does not establish a service outcome or a line-specific claims protocol..) |
