Research Report
What it covers
A multi-engine benchmark of how six AI search engines answer buyer-intent questions about enterprise third-party risk management, vendor risk monitoring and questionnaire automation. Covers 300,000 AI engine responses drawn from 10,000 queries across ChatGPT, Microsoft Copilot, Gemini, Google AI Mode, Google AI Overview and Perplexity in five markets, together with 1,551,000 cited sources classified by source type and 127 distinct product entries. Reports vendor share of voice, first-mention position against mention volume, cross-engine cited-source overlap measured by Jaccard similarity, market-by-market leading brands, and the share of cited pages that sit on vendors' own sites.
Why essential
OneTrust is the most-mentioned brand across 300,000 responses and the first-mention vendor in none of the six engines, while Bitsight holds that position in three: mention volume and ordinal position identify different leaders. The engines agree on nine of 72 brand strings but share a mean of only 0.19 of their cited domains, and 52.2% of everything they cite sits on vendors' own sites, with only 0.2% dead. The report separates the three measures and gives the per-engine and per-market tables behind them.
