## Marsh vs TechInsurance Professional Liability (E&O) Insurance Summary

TechInsurance reports a median E&O premium of $88 a month for the businesses it insures, while Marsh's professional liability practice places coverage for named enterprise industries and staffs attorneys, economists and actuaries to assess exposure.

## What Are the Key Differences Between Marsh and TechInsurance Professional Liability (E&O) Insurance?

### Published Pricing Versus a Specialist Team

TechInsurance's page puts a number on the table that Marsh's pages don't:

TechInsurance says its E&O policyholders pay a median of $88 per month, or $1,051 a year, with the exact premium depending on location, profession risk level, coverage limits, deductible, employee count, claims history and annual income. [3](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance") (Evidence: Company-reported; scope: Errors and omissions product page cost section; a company-reported median from TechInsurance's own book of business, not a published rate table..)

That figure gives a buyer a starting benchmark before ever requesting a quote. Marsh's page instead describes staffing its professional liability practice with attorneys, economists and actuaries to assess a client's exposure, a consultative model rather than a published rate. [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") For a buyer, that means TechInsurance sets an expectation up front while a Marsh quote depends on the specialist review.

When comparing Marsh and TechInsurance, use published pricing as a budget screen; the actual quote still decides the cost comparison.

### Who Each Page Targets

TechInsurance names IT and software professionals, cybersecurity and SaaS companies, insurance agents, real estate agents, tax preparers and consultants, and notes coverage is sometimes required by state law or licensing boards. [3](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance") Marsh instead names enterprise verticals: banking and broker/dealers, insurance companies and asset managers, venture capital, accountants, attorneys, architects and engineers, media and entertainment, technology, and healthcare and biotechnology. [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

A small tech-adjacent business fits TechInsurance's named list more closely, while a company in one of Marsh's named verticals is the audience its specialists describe serving.

### Explaining Claims-Made Coverage

TechInsurance's page explains that its E&O policies are claims-made, meaning coverage applies only if the policy was active both when the incident occurred and when the claim was filed, and recommends keeping the policy active or setting a retroactive date. [3](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance") Marsh's professional liability page describes what the coverage protects against but the reviewed page does not walk through claims-made mechanics the way TechInsurance's does. [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") A buyer comparing the two needs to ask Marsh directly whether its placement is claims-made or occurrence, since that page doesn't say.

## What Should You Confirm in Marsh and TechInsurance Professional Liability (E&O) Insurance Quotes?

- Ask TechInsurance how its published median premium compares to a quote for your specific profession and claims history. [3](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance")
- Ask Marsh which insurer it intends to place your policy with, since its pages don't name one. [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- Confirm the retroactive date on any claims-made quote from either. [3](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance") [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- Neither reviewed page publishes coverage limits; get both in writing. [3](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance") [1](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
