What Are the Key Differences Between At-Bay and Marsh Tech E&O Insurance?
A Defined Product vs a Custom Broker Program
At-Bay sells Tech E&O as a product with published coverage highlights, primary and excess options for revenue up to $5 billion, limits up to $10 million, and its Stance services. Marsh treats technology E&O as one of its professional liability specialties, alongside banking, insurance, asset management, media and healthcare, and names no insurer or limits. Choose At-Bay if you're a software or services company that wants known terms; choose Marsh if you run data centers or need E&O built into a larger program. 1 6
Software-Contract Wording vs Data-Center Towers
At-Bay's product is built around technology-company contract, IP, negligence and indemnity wording, including service credits you owe customers as covered damages. Marsh says off-the-shelf Tech E&O policies weren't built for the scale and concentration of modern data centers and can leave gaps, so it designs programs combining Tech E&O with property, casualty and other lines. A SaaS company fits At-Bay's form; a hyperscale facility fits Marsh's approach. 1 5
