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

Technology errors and omissions coverage can help pay when a customer claims your software, hosting, installation or technology advice caused financial loss. If you provide tech products or services, check each activity; cyber incidents and unrelated professional work need separate review. [8](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [9](https://doas.ga.gov/sites/default/files/2025-08/SPD-SP048%20Insurance%20and%20Bonding%20Guidelines%20August%202025.pdf "Insurance and Bonding Guidelines") [10](https://online.ogs.ny.gov/purchase/snt/awardnotes/7360022802AppendixJ_PRB01.pdf "Appendix J – Contractor’s Insurance Requirements, Information Technology Umbrella Contract – Manufacturer Based (Statewide)") [11](https://www.thehartford.com/professional-liability-insurance/errors-omissions-insurance/technology "Technology Errors and Omissions Insurance") [12](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/business-insurance/digitech-enterprise-risk-management-digitech-erm/documents/pdf/17010186-digitech-erm-12.17.pdf "DigiTech Enterprise Risk Management") [13](https://www.chubb.com/us/asset/smallbusiness/digitech-erm--new-business-application-small-business-pf-48204.pdf "Chubb DigiTech Enterprise Risk Management Policy — Technology E&O, Cyber and Privacy Short Form Application") [14](https://www.travelers.com/business-insurance/cyber-insurance/technology "Cyber Risk for Technology Companies")

## What Are the Key Differences Between Chubb and Markel Insurance Tech E&O Insurance?

### Bond Types and Contract Support

Markel lists contract, commercial, court, and probate bonds, and specifically mentions standalone and co-surety support for contract bonds. Chubb separates construction surety, commercial surety, transactional bonds for smaller or infrequent needs, and international bonds. For a contractor, Markel's co-surety option is a concrete point to explore; a buyer with an occasional smaller obligation can ask Chubb whether its transactional route fits the required bond form. [7](https://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance") [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### Direct Underwriting and Capacity Evidence

Chubb says it underwrites bonds directly and reports a $2.289 billion aggregate Treasury listing as of August 2026. Markel's reviewed surety page describes its product categories and target accounts but does not publish a comparable capacity figure in its offering record. If the obligee has a financial-strength requirement, request the precise surety entity and acceptable listing evidence from either proposal. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance")

### Transactional Online Access

Chubb offers its Surety Marketplace for transactional bonds, while other Chubb surety products go through appointed agents and brokers. Markel invites buyers or brokers to contact its underwriting team, without describing an online purchase path in the record. The distinction can matter for a small, infrequent bond with a deadline; ask whether your obligation can use the marketplace or needs agent placement. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance")

## What Should You Confirm in Chubb and Markel Insurance Tech E&O Insurance Quotes?

- Ask Markel which surety entity will issue the bond, whether co-surety is available for the contract, and what financial evidence the obligee can receive. [7](https://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance")

- Ask Chubb whether the required bond type qualifies for Surety Marketplace or must go through an appointed agent, and confirm the obligee accepts the proposed form. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
