## Research Scope and Use

Use this comparison to evaluate Chubb and Harper for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Harper says it serves consultants, agencies and licensed professionals broadly, while Chubb positions Pro ERM specifically for non-licensed professional-services firms instead.

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

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

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](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

### Licensed Professionals Land on Opposite Sides

Harper says it serves consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Chubb instead positions Pro ERM for non-licensed professional-services firms specifically, naming associations, consultants and event planners as examples. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### A Broker's Manual Review Against Built-In Policy Features

Harper says it reads a policy's exclusions line by line before a client buys, because two E&O policies with the same limit can respond very differently to a claim. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Chubb instead builds specific features directly into Pro ERM, including disciplinary-proceedings defense and personal injury coverage, rather than depending on a broker's after-the-fact review. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### Getting a Certificate in Hand

Harper says that when a client contract requires E&O, it places matching coverage and issues the certificate the same day. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Chubb instead has agents and brokers quote Pro ERM through its Cyber Central or Marketplace platforms, without describing same-day certificate issuance. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

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

- Confirm whether your business qualifies as "non-licensed" for Chubb's Pro ERM eligibility, or whether Harper's broader "licensed professionals" framing fits instead. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Ask Harper for the actual exclusions list from the policy it recommends, since its page describes the review practice but not specific wording. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Confirm Chubb's actual liability limit for Pro ERM, since the reviewed page names defense-cost treatment but not a limit figure. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Ask Harper for the pricing drivers behind your quote, and ask whether a same-day certificate is available if a client contract requires proof of coverage immediately. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

## Offering Details

| Criteria | Chubb Pro ERM (Professional Enterprise Risk Management) | Harper Professional Liability Insurance |
| --- | --- | --- |
| Role in This Line | Chubb underwrites professional errors and omissions coverage through Pro ERM, a single policy combining professional liability, media and cyber exposures for non-licensed professional-services firms. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Cyber Insurance Coverage & Products page, Professional Enterprise Risk Management section..) | Harper places professional liability coverage as a broker, writing the policy around the applicant's actual services rather than underwriting it, and describes a specialist handling the placement. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page introduction and 'Why Harper' section..)<br><br>Harper markets the identical policy under two catalogue entries, "Professional Liability" and "Errors and Omissions"; the E&O page states it is the same policy, just named what a given industry calls it. [8](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [9](https://www.harperinsure.com/coverages "What We Cover") (Evidence: Company-reported; scope: Coverage directory listing plus the E&O page's own description; a naming convention Harper states about itself, not a distinction between two products..) |
| Issuing Insurer | Not described in the reviewed sources. | The reviewed pages name pricing drivers (services performed, revenue, contract size) but do not name the issuing insurer or publish specific limit, retention or premium figures for this line. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [8](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") (Evidence: Not publicly disclosed; scope: Checked both the professional-liability and errors-and-omissions pages on 2026-09-23; neither names a carrier or a limit figure..) |
| Who It’s For | Chubb says Pro ERM is available to non-licensed professional-services firms of all sizes, naming examples including associations, consultants, business process administrators, event planners, interior and graphic design firms, marketing and PR firms, printers, staffing firms, travel agents and trustees. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Pro ERM Target Clients list..) | Harper targets consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision, since general liability doesn't cover a client claiming that work caused a financial loss. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page introduction and FAQ distinguishing it from general liability..) |
| Coverage Features | Beyond the Cyber ERM base, Chubb says Pro ERM adds E&O coverage including personal injury from professional services, a broadened definition of professional services that expressly includes professional technology services, coverage for independent contractors performing duties on the insured's behalf, automatic additional-insured status for clients when required by contract, and coverage for professional disciplinary proceedings. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Pro ERM Product Features list; subject to the policy as issued..) | Harper describes coverage for errors and omissions in the work itself, negligence allegations about professional judgment, and legal defense costs, with limits it says are matched to the client contracts that require the policy. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [8](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Professional liability page's four coverage tiles; the E&O page adds that claims often surface a year or more after the work was delivered. The issued policy and its exclusions control actual scope..) |
| Limits and Retentions | Chubb says Pro ERM includes coverage for 100% of defense costs for covered claims worldwide, but the reviewed page does not publish a separate liability limit or retention. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Pro ERM Product Features list..) | Not described in the reviewed sources. |
| Risk Services | Chubb says Pro ERM policyholders get access to legal counsel with extensive professional-liability experience, in addition to the general cyber-incident-response services shared with Cyber ERM. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Pro ERM Product Features list..) | Harper says it reads a policy's exclusions line by line before a client buys, because two E&O policies with the same limit can respond very differently to the same claim. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page 'We know this' section; a described review practice, not an independently verified outcome..) |
| How to Apply | Agents and brokers can quote Pro ERM through Chubb's Cyber Central or Marketplace quoting platforms. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Cyber Insurance Coverage & Products page quoting section..) | You request a quote online or by phone; if a client contract requires E&O, Harper says it places coverage matching that requirement and issues the certificate the same day. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page quote form and FAQ 'My client contract requires E&O. What now?'..) |
