## What Are the Key Differences Between Alliance Risk and Marsh Tech E&O Insurance?

### Specialist for Software and IT Firms vs Programs for Complex Risks

Alliance Risk places tech E&O for SaaS, AI, IT consultants, MSPs, developers, analytics firms, IT staffing and help-desk providers, and publishes typical limits from $250,000/$500,000 to $2 million/$3 million-plus. Marsh treats tech E&O as one of its financial and professional liability specialties and builds it into data-center programs alongside property and casualty. Choose Alliance Risk if you are a software or IT services company buying standalone tech E&O; choose Marsh if you run a data center or need tech E&O coordinated with a large property and casualty program.

### 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.
