What Are the Key Differences Between Aon and Newfront Professional Liability (E&O) Insurance?
Professional specialties and company stage
Aon identifies law, accounting and consulting firms for its practice; Newfront describes Executive Risk service to private companies from seed stage through later rounds and public companies, without making that eligibility specific to E&O. A growing company should ask Newfront how E&O fits its stage and Aon whether its profession falls within the named practice. 3 8
Risk advice and account services
Aon describes advisers using industry knowledge, data and tools for risk-management decisions. Newfront lists integrated claims and coverage negotiation and a dashboard for policies, certificates and billing. Ask which services attach to your E&O account and who handles claim discussions. 3 8
Placement and consultation
Aon says its practice helps arrange or advise on professional liability; Newfront asks prospects to request a consultation rather than issuing an instant quote. Both routes call for a conversation, so ask what underwriting material each needs and which carriers will be approached. 3 9

| Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | Newfront Executive Risk Errors & Omissions |
|---|---|---|
| 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. | Newfront lists Errors and Omissions (E&O) among the coverages its Executive Risk team places, alongside D&O, EPLI and fiduciary liability. Newfront brokers this professional-liability coverage rather than underwriting it, and distinguishes it from the technology E&O it places through its Cyber Risk practice. 8Company-reported. Executive Risk page's Key Coverages list; general professional E&O, not the technology E&O line placed by the cyber practice. |
| 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. | The reviewed page does not name an insurer for E&O placements; Newfront describes negotiating coverage on the client's behalf, so the issuing carrier would vary by placement. 8Not found in reviewed sources. Checked the Executive Risk page for a named E&O carrier; none was found. |
| 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. | Newfront says its Executive Risk practice serves private companies from seed-stage funding through later rounds and public companies it has worked with in over 500 instances, without breaking eligibility out by coverage line. 8Company-reported. Executive Risk page's Here for the Long Run section; a practice-wide statement, not E&O-specific eligibility criteria. |

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. | The reviewed page lists E&O as a named coverage but does not describe the specific insuring agreement, professional-services scope, or exclusions for that line; those terms come from the placed policy. 8Not found in reviewed sources. Executive Risk page as read on 2026-09-23; only a coverage-name listing was found for E&O specifically. |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms.

Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed. | Published limits or retentions for E&O coverage were not found on the reviewed page. 8Not publicly disclosed. Executive Risk page as read on 2026-09-23; limits are quote-specific for broker placements. |
| 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. | Newfront says it provides integrated claims and coverage negotiation across the Executive Risk lines it places, including E&O, and a proprietary dashboard for 24/7 access to policies, certificates and billing plus pre-populated renewal submissions. 8Company-reported. Executive Risk page's Committed to Client Advocacy and Industry-Leading Technology sections; applies to the practice generally, not documented as E&O-specific. |
| How to Apply | Confirm in your quote. | You engage Newfront for E&O placement by requesting a consultation, which asks for your industry, company details and the service you need rather than issuing an instant quote. 9Company-reported. General consultation intake, not an E&O-specific application path. |
