TechLeads scans public websites and detects OneTrust from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is OneTrust's website count divided by the website counts of all Privacy Compliance technologies we track; a site using two Privacy Compliance tools counts for both. Counts were last refreshed on October 8, 2026 and update daily.
