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. [4] [5] [10]

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. [8] [5]

What Should You Confirm in Marsh and Resilience Tech E&O Insurance Quotes?

  • Ask Marsh which insurers it would use; Resilience's policies are issued by Homeland Insurance Company of New York or of Delaware. [9] [5]
  • Check your revenue against Resilience's $25 million floor. [10] [4]
  • If you run a data center, compare Marsh's program design with Resilience's data-center appetite and $10 million maximum. [4] [10]
  • Ask both for limits, retentions and wording on the proposed policy. [10] [5]

The product page separately says capacity comes through "approved underwriting companies" rated by AM Best, without naming an insurer beyond the two Homeland entities.

The reviewed pages do not describe a claims process specific to technology E&O separate from this shared claims team. Claims & Incident Response page, accessed 2026-09-23; response-time and outcome statistics on that page are company-reported and not independently verified.company-reportedSource ↗
  • application: The reviewed technology E&O product page does not describe a self-service online application or quoting process; it routes visitors to request a quote rather than showing an application flow. Technology E&O product page, accessed 2026-09-23.not-disclosedSource ↗

Marsh suits data centers and other large-scale operators that need a custom program because standard Tech E&O forms weren't built for them; Resilience suits tech companies with $25 million to $10 billion in revenue that want up to $10 million from one insurer. Resilience runs its own 24/7 claims team.
