Companies Using TrustArc

I'm Mehmet Suleyman, CEO and co-founder of TechnologyChecker.io. I worked at Microsoft before this, on the Bing search team and then its AI team, where I got hands-on with web crawling infrastructure. This analysis covers 13,311 domains serving the TrustArc consent banner as of our September 2026 crawl, 6,548 of them matched to a company record. One number reframes the rest: where the TrustArc notice names the account it belongs to, 2,319 domains resolve to 597 accounts, about 3.88 domains each. That is the most account-shaped base we have published.

Growth trajectory

Our records put TrustArc on 9,266 domains in June 2026, 11,993 in July, 12,650 in August and 13,311 in September. Very little of that is new business. Of 4,178 domains first detected in May, 4,102 were new to our crawl within three days, and July repeated it at 1,668 of 2,054. The set of domains we crawl turns over every month as dead sites drop out and newly found ones come in, and our detection signals widen over time. September reads more like adoption: only 133 of 768 new detections were domains new to us.

The count is a floor. TrustArc was TRUSTe until 2017, and 540 domains still serve the legacy consent.truste.com script without the current host.

"2,319 domains resolve to 597 accounts. Take 13,311 as a customer list and you build a prospecting file four times too big, pointed at the wrong people." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales Signal: Don't time outreach to the chart. The rise into August is our coverage catching up. React to account-level events instead: a portfolio changing banner, or a site still running the legacy TRUSTe script.

Customer profile

The size table looks like a small-business product. 42.96% of the 6,097 sized companies employ ten people or fewer, another 23.78% employ 11 to 50. Then look at who they are: Compass agent sites, Coldwell Banker brokerages, IHG hotel brands. None of them bought anything; the contract sits with the parent. The buyers are in the other tail, where 636 companies (10.43%) employ more than 1,000 people: IBM, Oracle, SAP, Goldman Sachs, Samsung, Philips. The 2010s lead the founding decades at 29.99%, yet 8.8% predate 1960. TrustArc's own site claims 1,500+ customers. That is the vendor's published figure, and our domain count neither confirms nor contradicts it; the two count different things.

Sales Signal: Filter on employees above 1,000 before you touch this list. A four-person brokerage office has no privacy budget and no decision rights.

Industry and geographic concentration

Financial Services is the largest vertical at 15.17% of 5,781 matched companies, and Investment Management adds 3.89%, so regulated money is 19.06% of the base. The three rows underneath are fleets. Real Estate reads 8.02% and is mostly Compass (127 domains), Coldwell Banker (75) and Century 21 (48). Hospitality reads 5.12% and is largely IHG at 111 domains. Veterinary Services reads 6.43%, or 372 domains, and 313 of those share one WordPress theme served from a single Azure CDN endpoint; all three sites we sampled are NVA clinics.

Geography is narrow. The United States holds 3,769 of 6,334 placed companies and the United Kingdom 1,383, which is 81.3% between them. For a vendor whose category exists largely because of GDPR, continental Europe is close to absent, partly our own English-language skew.

Sales Signal: Two lists. Financial services and investment management in the US and UK is where the buying committees sit. The fleets are one conversation each: sell IHG or NVA once and you reach hundreds of domains.

Migration patterns

456 domains have moved from TrustArc to OneTrust, 172 of them in the last 30 days, against 175 coming back. Osano takes 122. Both corridors survive the base-rate test: of 2,390 domains that left TrustArc entirely, 19.08% now run OneTrust against 2.36% of the domains that stayed, an 8.1x lift at direction 2.6:1, and Osano reads 5.1% against 0.66%, 7.7x at 61:1. For scale, 2,656 domains dropped TrustArc since we began tracking it in March 2026, 42.9% of them seen only once.

The unit matters here. Those 456 domains are 73 distinct companies among the 90 that carry a company record, because an account moves its brand portfolio in one operation. Philips moved 57 domains on 10 September 2026 and Colgate-Palmolive 30 on 27 August. No single day is more than 12.5% of the corridor, so this isn't one large customer leaving.

"Read the migration table twice. 456 domains left for OneTrust, and they belong to 73 companies. Both numbers are true and they describe completely different problems." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales Signal: The switchers are visible and arrive in batches. Watch for the first two or three domains of a portfolio changing banner; the rest usually follow inside the quarter.

Technology ecosystem

Across the 13,239 domains live today, Google Tag Manager covers 83.81% and Google Analytics 71.38%. Ordinary. What sits underneath is not: Adobe Experience Manager on 10.46%, Adobe Experience Platform Launch on 14.01%, Adobe DTM on 12.18% and Adobe Analytics on 9.08%, while WordPress manages only 13.72%. On a general consent tool those last two figures are reversed. Two Adobe tag managers side by side, one the retired DTM, says the tagging estate hasn't been touched in years, which is where a consent banner becomes hard to change.

Sales Signal: Cross-filter TrustArc with Adobe DTM to find the accounts carrying the most technical debt. Hardest to displace, likeliest to buy help.

G2 review signals

The review data contradicts itself, and that is the finding. Customer support is the second-largest pro at 49 mentions and the largest con at 15. We aren't going to quote only the flattering half. The steadier complaint is setup: steep learning curve (13), difficult setup (12), learning difficulty (12) and time-consuming setup (12) total 49 mentions, matching the support praise exactly. Our own data explains part of it: readable accounts average 3.88 domains, and reviewers who call setup time-consuming describe managing multiple global websites.

Sales Signal: Onboarding is the wedge, not features. An account with dozens of domains under one notice has paid that cost already and will resist paying it twice, which cuts both ways.

Key takeaways

1. An account base, not a domain base. 2,319 domains resolve to 597 accounts, 3.88 each.
2. The count is a floor. 540 domains still serve the legacy TRUSTe script.
3. Three industry rows are fleets. Real Estate 8.02%, Veterinary Services 6.43% and Hospitality 5.12% are Compass, Century 21, NVA and IHG.
4. Regulated money is the real demand. Financial Services 15.17% plus Investment Management 3.89%, 81.3% of it in the US and UK.
5. OneTrust is the exit. 456 domains and 73 companies, at an 8.1x lift.
6. The stack is Adobe. Experience Manager 10.46% against WordPress 13.72% is an enterprise shape.

Sales applications

Outreach template for privacy and web teams:

"Hi [Name], we track the TrustArc banner across 13,311 domains, and [Company] shows it on [count] of them under a single notice. The accounts we watch move to OneTrust in portfolios, 20 to 60 domains in a day, and sequencing is where teams lose a quarter. Worth fifteen minutes?"

Targeting strategy: On TechnologyChecker.io, filter the TrustArc base to companies above 1,000 employees in the US or UK, then cross-filter on Adobe Experience Manager or Adobe DTM. That narrows 6,548 enriched companies to the enterprise Adobe accounts and drops the fleets in one step.

Competitive angle: The 172 domains that moved to OneTrust in the last 30 days are mid-migration and open to services. The ones still on the legacy TRUSTe host are open to almost anything.

The full base is filterable at TechnologyChecker.io, covering 13,311 domains serving the TrustArc banner and 6,548 enriched companies.
