Key Differences in Tech E&O Insurance

Specialist Placement Versus a Data-Center Building Block

Alliance Risk places Tech E&O for technology companies that build, deploy or advise using software. Marsh treats technology E&O as one of its financial and professional liability specialties, with dedicated attention to the technology industry, and separately names it as a building block inside data-center insurance programs. Neither reviewed page names the issuing insurer. ² ⁸ ⁷

What Each Practice Says About Form Gaps

Alliance Risk describes typical Tech E&O as covering failure to perform, errors in deliverables, unmet specifications, unintentional IP infringement, product failure and data loss caused by the company’s own mistakes, and offers a no-charge review for coverage gaps and retroactive dates. Marsh says off-the-shelf technology E&O policies were not built for the scale and concentration of modern data centers and can leave gaps, so it designs programs that combine technology E&O with property, casualty and other lines. ² ⁷

Audience and Published Limits

Alliance Risk lists SaaS, AI, IT consultants, MSPs, developers, analytics firms, IT staffing and help-desk providers, and publishes typical limits from $250K/$500K to $2M/$3M+. Marsh names technology among specialized industries its professional-liability experts serve, alongside banking, insurance, asset management, media and healthcare, and does not publish Tech E&O limit figures on the reviewed pages. ² ⁸

What to Confirm in Tech E&O Insurance Quotes

Ask whether Marsh is quoting a standalone Tech E&O placement or a data-center program that packages the line with property and casualty. ⁷
Compare Alliance Risk’s typical $250K–$3M+ limits with whatever Marsh places, since Marsh’s pages do not publish amounts. ² ⁸
Get the issuing insurer from both; neither page discloses it. ² ⁸
Confirm whether Alliance Risk’s contract-and-concentration intake matches the information Marsh will need for a data-center or professional-liability submission. ² ⁷
