## What Is Founder Shield Insurance?

Founder Shield is a broker for venture-backed startups: you apply online in under 15 minutes, and an advisor shops its 200+ carrier markets to build a program that changes as your products and locations change. It doesn't insure you itself, so ask which insurer carries each policy.

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

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [13](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [14](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [15](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [16](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## What Are the Key Differences Between CNA and Founder Shield Professional Liability (E&O) Insurance?

### E&O Buyer Groups

CNA’s MPL target list includes consultants, staffing firms, advertising agencies, and event planners, but it is not a complete eligibility rule. Founder Shield markets E&O to consultants, media and advertising agencies, SaaS marketplaces, software developers, and venture-capital firms performing services for others. The stated audiences overlap in consulting and advertising, while Founder Shield also names several technology-oriented groups; actual acceptance remains subject to the proposed policy and underwriting. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") [11](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance")

### E&O With Technology and Cyber Lines

CNA’s Epack 3 brochure describes a modular package combining technology and professional liability with cyber and media. [5](https://www.cna.com/sites/default/files/assets/epack-3-cyber-media-technology-professional-liability-ss.pdf?ContentCache=NONE&MOD=AJPERES "Epack 3 – Cyber, Media, Technology & Professional Liability") CNA’s current cyber page describes EPS Plus as E&O and cyber for professional-services firms. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") Founder Shield says E&O is often packaged with technology E&O and cyber because the claims can intertwine. [11](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance") Both describe connecting E&O with technology or cyber coverage, but only CNA names these two package configurations; Founder Shield’s wording describes a common packaging practice, not a guaranteed package.

## What Should You Confirm in CNA and Founder Shield Professional Liability (E&O) Insurance Quotes?

- Ask Founder Shield whether the proposed placement includes E&O, technology E&O, cyber, or separate policies. [11](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance")
- Ask CNA which of Epack 3 or EPS Plus is being quoted and how its schedule groups the lines. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")

| Issuing Insurer | Confirm in your quote. | Founder Shield says it places policies, including Founder Shield Errors & Omissions Insurance, only with carriers rated A- or better by AM Best, chosen for the client's industry.

[4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions") (Evidence: Company-reported; scope: The page is a summary and does not define covered services, contract exceptions or policy triggers..) | Founder Shield lists defense costs, defense against disciplinary or regulatory proceedings, lost-earnings coverage, and claims from errors by employees or contractors as what E&O responds to. [11](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance") (Evidence: Company-reported; scope: Product page; the issued policy and declarations control actual coverage..) |
| Risk Services | CNA describes dedicated claims and risk-control support for its cyber, media, technology and professional-liability business.
