Companies Using Fraud0

The useful thing about Fraud0 is its script address. The tag names the account it reports to, so in our October 2026 crawl I could read who owns each install. Of the 738 domains carrying the tag, the 648 where the address shows the account sit under 275 accounts, and 75 of those accounts are inactive. Their sites still load the tag, Fraud0's server answers with one line saying the account is inactive, and nothing is measured. With aliases, that's 195 domains. This page counts the other 543, 276 of them matched to a company.

One point on the chart

The usage chart shows a single October 2026 reading of 543 domains. Our August and September totals counted every site carrying the tag, dead accounts included, so they would show a drop that never happened. Since we began covering Fraud0 on 4 August, 97 domains dropped it on at least one hostname; 20 still run it on another, and many of the rest are extra domains of brands that kept it, such as LBS office sites and a solar installer group's country sites.

"A quarter of the sites carrying Fraud0's tag ran an account that's been switched off. That's why I read the account id before I count a site." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: treat this as a list of 543 live domains and 200 active accounts. The 75 inactive accounts are a separate list: companies whose account was switched off, most likely at the end of a trial or contract.

Accounts, not domains

Fraud0 users spread one account over many domains. LBS runs one across 28 domains, mostly local office sites, Sartorius across 24 country and brand sites, an outdoor-clothing brand across 23 country sites and Custom Truck One Source across 22. A solar installer group covers 16 domains, including local installers' sites that now forward to the group's location pages. I found no agency or platform spreading one account over unrelated businesses, apart from one club website builder. Still, 135 of the 200 active accounts sit on a single domain, so the long tail is ordinary single-site buyers.

Sales signal: dedupe by account before you size a campaign. Two hundred active accounts is the real addressable count, and the multi-domain ones are group marketing teams that buy centrally.

Who the customers are

Fraud0's matched companies are bigger than ClickCease's. 19.48% of those with a known size have more than 500 staff, against 1.99% on ClickCease's profile, though 32.03% have 1 to 10 employees. They're also older: 11.54% were founded before 1960 and 14.62% in the 2020s. The large users I checked include Sartorius, HCLSoftware, Motel One, Custom Truck One Source and Globus. Fraud0's own 7 October 2026 press release names HelloFresh, Condor, ABOUT YOU and the Otto Group as customers. Our crawl records active Fraud0 accounts on several HelloFresh Group sites, but their bot walls kept me from loading them myself.

Sales signal: pitch the marketing lead at a mid-sized company that buys search ads. Large companies are a far bigger share here than on ClickCease.

A German-speaking base

Germany has 169 matched companies, the United States 30, and Switzerland and Austria 12 each. The three German-speaking markets hold 193 of the 276 matched companies. ClickCease's profile shows 208 German companies, so Fraud0 comes close to that from about one sixtieth as many domains. Retail leads the industries at 10.23%, 13.02% with fashion, then software at 7.91%. Construction (6.98%) is 10 ISOTEC-named firms out of 15, banking is mostly LBS offices and utilities are Stadtwerke, EnBW and Yello.

Sales signal: for a German-language martech or consent pitch, this list is well qualified. Outside the DACH region it's thin: 30 American companies won't carry a US campaign.

No switching, and almost no overlap

There's no migration table here, because no switching row passed our tests. The overlap with rivals is close to zero. Only 5 of the 543 Fraud0 domains also run ClickCease, 2 ClickGUARD and 1 TrafficGuard. On these sites, a company picks one click-fraud tool and wires it into its ad accounts.

"Fraud0's churn looks like brands trimming domains. Its switched-off accounts didn't move to a rival either: only 3 of the 195 domains we removed run ClickCease or TrafficGuard." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: for a rival vendor, the inactive accounts are the warm list. They already set up a tool for invalid traffic once, and the tag still sits on their pages.

The stack around it

Consent managers are common. Usercentrics runs on 42.54% of the 543 domains, Cookiebot and Cookie Control on 13.81% each and OneTrust on 12.71%. That's partly a channel: Usercentrics' integration page lets its customers create a Fraud0 account from inside the Usercentrics admin, and Fraud0's about page lists a Usercentrics co-founder among its backers. Google Analytics is on 54.88% and Microsoft Advertising on 18.78%. On some sites the tag waits for consent; Motel One's sent events only after I accepted its banner.

Sales signal: many Fraud0 sites already run a consent manager, so privacy-safe measurement and server-side tagging are easier conversations here than on the average paid-search site.

What it costs

Fraud0's pricing page (15 October 2026) lists Starter at 50 euros a month for up to 50,000 monthly sessions, Pro at 150 euros for up to 100,000 and Enterprise from 600 euros, or 40, 120 and 500 euros billed annually. A success fee of a third applies to any ad spend recovered through refunds. The homepage now leads with that refund agent.

Sales signal: session-based pricing means traffic spikes reach the renewal. Sites near the 100,000-session line face the step from Pro to Enterprise.

Key takeaways

1. 543 domains with a live account, 21st of 32 in Fraud Prevention, after removing 195 of the 738 that carry a dead or borrowed tag.

2. 200 active accounts, and the biggest multi-domain accounts are one brand's country or office sites.

3. A German-speaking, mid-sized, older base: 193 of 276 companies in DACH and 19.48% above 500 staff.

4. Almost no overlap with ClickCease, so the two rarely compete on the same site.

5. Consent managers are common, Usercentrics alone at 42.54%.
