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

The Hartford publishes average E&O premiums and reporting-period terms by product; Mylo compares quotes without disclosing pricing.

## Research Scope and Use

Use this comparison to evaluate Mylo 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

The Hartford underwrites professional liability directly with published average premiums and an extended reporting period, while Mylo compares E&O quotes across multiple carriers and explains claims-made versus occurrence forms.

## What Is Mylo Insurance?

Mylo is an independent insurance broker for small and growing businesses.

## What Is The Hartford?

The Hartford is the brand of The Hartford Insurance Group, Inc., whose subsidiaries underwrite property-and-casualty insurance and employee benefits. Small-business buyers can start online or by phone or work through independent agents, while the issuing company and state eligibility still have to be confirmed on a quote.

## 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. [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

### Underwriter Versus Comparison Broker

The Hartford's page describes underwriting professional liability directly, protecting businesses for mistakes in the professional services provided to clients. [8](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage") Mylo instead describes comparing quotes from multiple business insurance companies to find a combination of coverage and price, rather than underwriting the policy itself. [3](https://choosemylo.com/business/product-professional-liability "Professional Liability Insurance")

### Reporting-Period Terms on One Side

The Hartford's page details a specific structure Mylo's page doesn't quantify:

The Hartford says the policy can cover claims of negligence, misrepresentation, inaccurate advice, personal injury (libel/slander) and copyright infringement, plus defense costs. Many of its professional liability policies are written on a claims-made basis with a retroactive date and an extended reporting period (typically 30-60 days, extendable to a year or more for an added cost), though some are written on an occurrence basis. [8](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage") (Evidence: Company-reported; scope: Professional liability product page as read 2026-09-23. General coverage and policy-form description; the issued policy controls..)

Mylo's page explains claims-made versus occurrence forms in general terms and says tail coverage can be added to a claims-made policy, but does not publish a specific reporting-period length like The Hartford's 30-60 day figure. [3](https://choosemylo.com/business/product-professional-liability "Professional Liability Insurance")

### Pricing Transparency

The Hartford publishes average minimum monthly premiums by product, ranging from $38 for Healthcare Professionals Professional Liability to $239 for Architects and Engineers Professional Liability. [8](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage") Mylo's page does not publish a comparable price range; it describes shopping the market rather than quoting a figure directly. [3](https://choosemylo.com/business/product-professional-liability "Professional Liability Insurance")

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

- Ask The Hartford whether your profession falls under one of its published pricing categories or a different underwriting tier. [8](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage")
- Ask Mylo whether the quote it finds for you is claims-made or occurrence, and what a tail endorsement would cost. [3](https://choosemylo.com/business/product-professional-liability "Professional Liability Insurance")
- Confirm the extended-reporting-period length and cost on any claims-made quote from either. [8](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage") [3](https://choosemylo.com/business/product-professional-liability "Professional Liability Insurance")
- Neither page publishes standard coverage limits; get them in writing before binding. [8](https://www.thehartford.com/professional-liability-insurance "Professional Liability Insurance Coverage") [3](https://choosemylo.com/business/product-professional-liability "Professional Liability Insurance")
