# Coalition vs The Hartford Professional Liability (E&O) Insurance

Coalition sells MPL only as extra questions on an Active Cyber quote; The Hartford publishes average monthly premiums for standalone miscellaneous professional liability and a professional-liability endorsement.

## Research Scope and Use

Use this comparison to evaluate Coalition and The Hartford 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

Coalition designs MPL as an add-on that combines with certain Active Cyber Insurance policies and is sold through appointed brokers, not as a stand-alone policy. The Hartford sells professional liability (E&O) and publishes average minimum monthly premiums by product, including Misc. Professional Liability Standalone at $62.

## 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. [11](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [12](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [13](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [14](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

### Add-On to Cyber Versus a Hartford E&O Product

Coalition designs and distributes miscellaneous professional liability as coverage that combines with certain Active Cyber Insurance policies, sold through appointed brokers. The Hartford sells professional liability, also called errors and omissions insurance, as its own product line for mistakes in professional services to clients, including claims that turn out to be baseless. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [10](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage")

Coalition sells MPL only as an addition to an Active Cyber Insurance quote, saying it takes just a few extra questions to add, rather than as a stand-alone policy. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") (Evidence: Company-reported; scope: Miscellaneous Professional Liability product page as read on 2026-09-23..)

### Duty to Defend Versus Claims-Made Mechanics

Coalition says MPL pays defense, settlements and judgments on a duty-to-defend basis even when the business is not ultimately at fault. The Hartford lists negligence, misrepresentation, inaccurate advice, personal injury and copyright infringement plus defense costs, and says many of its professional liability policies are claims-made with a retroactive date and a typical 30-to-60-day extended reporting period, though some are occurrence. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [10](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage")

### Who Each Names as a Typical Buyer

Coalition markets MPL to any business that performs professional services, with examples including consultants, marketing and PR firms, staffing firms, printers, interior decorators, photographers and videographers, and property managers. The Hartford targets businesses that sign contracts requiring coverage, offer professional services to customers, or regularly give advice, and lists accountants, consultants, interior designers, advertising agencies, graphic designers, technology professionals and healthcare professionals. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [10](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage")

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

- Ask Coalition whether MPL can be added to your Active Cyber quote and which unaffiliated surplus-lines insurer would issue it; the disclaimer page does not name an MPL carrier. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [6](https://www.coalitioninc.com/legal/disclaimer "U.S. Disclaimers")
- Ask The Hartford whether the quote is standalone MPL, an endorsement, or another named professional-liability product, and what limit sits behind the published average premium. [10](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage")
- Ask The Hartford whether the form is claims-made or occurrence and how long the extended reporting period would run. [10](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage")
