What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2
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. 4,5,6,7
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. 10,11,12,13,14,15,16
Key Differences in 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. 3 8
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. 3 8
