Free Gap Review vs Custom Program Design

Alliance Risk describes typical cover for failure to perform, errors in deliverables, unmet specifications, unintentional IP infringement, product failure and data loss from your own mistakes, and offers a free review of gaps and retroactive dates. Marsh says off-the-shelf tech E&O wasn’t built for the scale and concentration of modern data centers and can leave gaps, so it designs combined programs instead. Marsh publishes no tech E&O limits.

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

Alliance Risk suits SaaS, AI, IT consulting and managed-service firms, publishing typical limits from $250,000/$500,000 to $2 million/$3 million-plus and a free gap review. Marsh suits large or complex risks such as data centers, combining tech E&O with property and casualty because standard forms leave gaps.
