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 Embroker?
Embroker suits technology firms seeking a single application for management coverage plus eligible Tech E&O and cyber, and law firms seeking a grouped package; buyers needing only standard small-business coverage should compare direct carriers. 4,5,6

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. 8,9,10,11
Key Differences in Professional Liability (E&O) Insurance
Coverage and Policy Design
Aon describes professional liability as a tailored structure for professional-services firms, without enumerating covered allegations. Embroker sells a standalone professional-liability policy for fee-based advice or services, covering claims alleging errors, negligence, missed standards or deadlines, misleading statements or breach of contract, plus attorney fees. That description helps buyers identify the allegation types to test against their own client contracts and services. 3 7
Buying Route and Terms
Embroker expressly separates this policy from lawyers’ liability and technology E&O/cyber. It says personal injury, property damage, cyberattacks, employee injuries and discrimination are outside this form and belong to other lines. Aon’s overview does not publish a comparable exclusion list. Embroker provides an online quote and offers aggregate or first-dollar-defense deductible choices; ask how defense costs affect the deductible and compare those terms with the form Aon places. 3 7

Aon vs Embroker: Professional Liability (E&O) Insurance: documented features by provider
| Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | Embroker Professional Liability Insurance |
|---|---|---|
| Role in This Line | Aon presents Professional Liability / E&O as a line its Professional Services Practice helps arrange or advise on for professional-service firms. 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. 3Company-reported. Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement. | Embroker sells professional liability, also called errors and omissions insurance, as a standalone product for professional-services businesses, separate from its lawyers professional liability program and its bundled technology E&O/cyber product. 7Company-reported. Product-page description; not a statement about the issuing insurer. |
| 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. 3Not found in reviewed sources. 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. That audience scope does not establish eligibility for every firm or other business. 3Company-reported. Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement. | Embroker markets the policy to anyone who provides professional advice or services for a fee, listing accountants, bookkeepers, consultants, real estate agents, home inspectors, and IT and healthcare professionals as example buyers, while noting lawyers and doctors typically use specialized malpractice coverage instead. 7Company-reported. Product-page eligibility and industry-example sections; not a guarantee of coverage for a particular business. |
| 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. 3Company-reported. 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. | Embroker lists coverage for claims of errors, omissions or negligence, failing to meet expected standards or deadlines, false or misleading statements, breach of contractual obligations, and attorney fees from covered claims. 7Company-reported. Product-page What's covered section; the issued policy and declarations control. Embroker says the policy does not cover personal injury or property damage (handled by general liability), cyberattacks and data breaches (some tech E&O policies offer limited cyber coverage, but full protection needs a separate cyber policy), employee injuries, or employee discrimination claims (handled by EPLI). 7Company-reported. Product-page What's not included and 'Do I need Professional Liability insurance if I already have General Liability coverage?' sections. |
| 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. 3Not publicly disclosed. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed. | Embroker says the policy carries a deductible, that a higher deductible generally lowers the premium, and that buyers can choose an aggregate (once-annually capped) deductible or a first-dollar-defense option that applies the deductible only to damages, not legal costs. 7Company-reported. Product-page 'Does it have a deductible?' section; specific dollar limits and deductible amounts are not published and depend on underwriting. |
| 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. 3Company-reported. Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated. | Confirm in your quote. |
| How to Apply | Confirm in your quote. | Embroker offers an online quote for professional liability through its digital platform, describing underwriting factors including business size, industry risk, location and claims history. 7Company-reported. Product-page 'Quick quotes' feature and cost-factor list; no quote was requested during this research. |
