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

Coverage design and fit

AIG describes claims alleging errors or omissions in providing technology services, including customer economic loss. Marsh focuses on technology E&O as one element of data-center programs, saying standard forms may not fit the scale and concentration of modern facilities and combining E&O with property, casualty, and other lines. Data-center operators should compare the E&O wording with infrastructure dependencies and the rest of the insurance tower. [2] [5]

Eligibility, services, and placement

Marsh names technology as one of its professional-liability specialties and designs coordinated programs for data centers. AIG describes Technology Services E&O for service providers but does not identify data-center-specific terms. Ask whether the facility operator or its technology vendors are the insured and how downtime losses are treated. [2] [5]

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

  • Ask AIG Technology to specify the form terms and limits relevant to your technology services. [2]
  • Ask Marsh Technology to confirm how its stated program details apply to your business and proposed policy. [5]

Marsh brokers and designs multi-line data-center programs; AIG markets a defined Technology Services E&O product.
