## What Are the Key Differences Between Marsh and Resilience Tech E&O Insurance?

### Custom Data-Center Programs vs a Defined Product

Marsh brokers tech E&O and designs data-center programs because, it says, off-the-shelf tech E&O wasn't built for that scale and concentration of risk. Resilience writes Tech E&O for six segments: tech services (including MSPs, MSSPs, consulting, staffing, storage and resellers), hardware and networking, data centers, telecom, software (including AI, security and payments) and web services, for companies with $25 million to $10 billion in revenue and limits up to $10 million, primary or excess. Choose Marsh if you run a large data center or need a multi-line program built around form gaps; choose Resilience if you fit its revenue band and want a defined policy. [1](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [2](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [3](https://cyberresilience.com/products/technology-errors-and-omissions-insurance "Technology E&O")

### Insurer's Claims Team vs Broker Advice

Resilience runs a fully in-house 24/7 claims and incident-response team with one manager from triage through settlement. Marsh's pages describe professional-liability specialists but no tech E&O claims process, and name no insurer or limits. If your concern is who handles a claim at 2 a.m., Resilience answers it on paper; ask Marsh which insurer and claims team its program would use.
