When AI engines like ChatGPT, Claude, Perplexity, and Gemini field questions about regulatory compliance consulting firms, EY comes up most often, appearing in 50% of AI-generated answers across tested queries. Protiviti and Deloitte round out the top three. That means if a buyer asks an AI assistant for a shortlist, EY has an even-odds chance of being named first.
The sources AI engines cite most when answering these queries include protiviti.com alongside smaller specialist sites like jjccgroup.org, acaglobal.com, corecls.com, and oysterllc.com. The presence of niche compliance-focused domains alongside a major firm's own site suggests AI engines are drawing from topical authority pages and practitioner-level content, not just broad review aggregators. Firms that publish detailed, specific compliance content earn disproportionate visibility.
For a buyer using this page, AI visibility is a proxy for third-party validation and topical credibility. Before choosing a firm, check whether they publish current, substantive content on your specific compliance area (financial services, healthcare, data privacy, etc.). A firm ranked highly here has demonstrated consistent recognition across multiple AI systems, which reflects breadth of coverage and external citations rather than self-reported credentials.
At a glance
What we observed in this categoryauto-generated
EY leads the regulatory compliance consulting category with 50% visibility, more than four times the 12.5% held by Deloitte, PwC, and Protiviti. That gap is significant because the category average visibility sits at just 4.4%, meaning EY is appearing in AI responses at a rate roughly eleven times the norm. Fifteen of the twenty tracked brands show zero visibility, confirming this is a highly concentrated landscape where the top position carries outsized strategic weight.
Protiviti presents the most striking divergence between visibility and citation. Its visibility of 12.5% is identical to Deloitte and PwC, yet its citation rate is 50% compared to 0% for both those firms. EY leads on visibility but holds 0% citation, meaning AI surfaces EY by name but does not link to its content as a source. Protiviti is the only brand in the top five that Google AI Mode both mentions and actively cites.
The top cited sources list reveals that Google AI Mode is anchoring heavily on niche and specialist domains such as jjccgroup.org, acaglobal.com, corecls.com, regcompliancewatch.com, and oysterllc.com, none of which are the major consulting brands dominating visibility. Protiviti.com is the sole top-five brand appearing in that cited sources list. This pattern suggests AI is drawing factual or structural content from smaller specialist publishers rather than the large firms it names in responses.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically. How AI search ranking works →
