What Is Marsh?
Marsh suits technology and larger businesses seeking specialist cyber placement or broad global risk advice; small firms wanting a quick standard quote should compare its MMA route or digital agencies. 5,6,7,8
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. 11,12,13,14,15,16,17
Key Differences in Tech E&O Insurance
Data-center programs and contractual technology coverage
Marsh identifies technology E&O as a financial and professional liability specialty and says its data-center programs combine it with property, casualty and other lines because standard forms may leave concentration gaps. CNA describes Technology E&O for technology businesses and says it is intended to support contractual requirements. A data-center operator should compare Marsh’s integrated program design with CNA’s proposed line form, focusing on shared infrastructure exposures and the exact customer contracts. 4 9
Specialist placement and support
CNA describes dedicated claims and risk-control support across technology and professional-liability business. Marsh describes specialist attention to technology and data-center risks but the reviewed claims do not list a comparable claims service. That is a difference in published detail, not proof that either provider lacks a service. Ask Marsh who coordinates claims across the combined program, and ask CNA whether the technology form can be coordinated with property and casualty coverage for your facility. 4 10

Marsh’s global Trustpilot profile has a poor 1.3/5 score. Treat it as a service warning to investigate with your proposed team; it does not isolate US commercial accounts.[2][4][7]
