Companies Using Signifyd

Fraud tools are hard to count from outside, because merchants rarely put them where a crawler looks. Our October 2026 crawl finds Signifyd live on 3,769 domains, 1,584 of them matched to a company. A domain counts when a page creates Signifyd's SIGNIFYD_GLOBAL object or loads a script from signifyd.com. On 10 October I loaded the 50 sites in our table: 40 loaded the script, in four versions, a script tag and a company toolkit for direct integrations plus separate tags for Shopify and BigCommerce stores. I couldn't confirm the other 10, mostly because of bot walls or country redirects.

Why 3,769 is a floor

Signifyd's script collects device and session data for the order decision, and its pricing page lists JavaScript tags among the ways to integrate. A merchant needs that data when an order is placed, so many load the script on checkout alone. Our crawl reads home pages and storefronts, and those merchants don't show up. Some stores do load it early. Rodan + Fields, a Signifyd case study, sets an order session ID for the script on its home page. The real customer count is higher than ours by an amount we can't measure from outside.

Sales signal: treat a Signifyd hit as confirmed and a miss as unknown. Before you write off a mid-market store as having no fraud vendor, look at its checkout.

Flat since July

The chart reads 3,055 domains in June 2026, 3,626 in July, 3,708 in August, 3,679 in September and 3,769 in October. The June to July step of 571 reflects changes on our side, both the domains we cover and the signals we detect Signifyd with, and the set of domains we crawl turns over every month as dead sites drop out and new ones are added. Since July the count has moved by 143. 815 domains dropped Signifyd between 16 March 2026, when we began tracking removals, and October, and 146 of them still run it on another hostname.

"Fraud tools often live on the checkout page, so a crawl mostly sees the merchants who load Signifyd early. Read 3,769 as the visible part of the base, not all of it." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: this is a steady pool, not a fast-growing one. Sell to it on fit; there's no growth story to lean on.

The category table needs reading

Signifyd is 9th of 32 in Fraud Prevention with 2.50%. The top of that table is mostly something else: Google Ad Traffic Quality and ClickCease fight click fraud on ads, and Confiant screens ad quality. Forter is 3rd with 21,652 domains, but that count is dominated by one restaurant online-ordering platform's sites. Among vendors that decide whether an order ships, Signifyd's 3,769 sits behind Sift (12,024) and NoFraud (6,382) and ahead of Riskified (2,328) and ClearSale (1,062).

Sales signal: benchmark Signifyd against order-fraud vendors only. On that view it is a mid-sized vendor, and the 9th-place rank is mostly a category artefact.

Who the customers are

43.31% of matched companies with a known size have 1 to 10 employees, 28.38% have 11 to 50 and 16.48% have 51 to 200. 53 have more than 1,000 staff, including Philips, Abercrombie & Fitch, Eddie Bauer and Mattel, which runs it on its Mattel Creations collectors' store. The base is older than Attentive's: 8.25% were founded before 1960, against 5.56%, and only 5.81% in the 2020s, against 9%. Signifyd's customers page features Philips, Rodan + Fields and Rad Power Bikes among its case studies, and all three load the script in our crawl.

Sales signal: the buyer is ecommerce or payments operations. Signifyd's own pricing page talks about approval-rate targets, which tells you how the category sells: on orders approved as much as on fraud caught. Lead with approvals.

Canada, furniture and beauty

The United States has 1,157 matched companies and Canada 124, ahead of the United Kingdom (90) and Australia (52). On Attentive's profile the order is reversed, 369 UK to 209 Canada. Giant Tiger, Sail, Aubainerie and Moose Knuckles all load Signifyd. By industry the three retail labels cover 42.32%, and the list has clear clusters: furniture (Design Within Reach, City Furniture, Slumberland, Herman Miller's store), beauty (Elizabeth Arden, Huda Beauty, Arbonne) and outdoor gear (Eddie Bauer, YETI, KEEN, Vuori).

Sales signal: Canadian retail is a real segment here. Payment and checkout vendors with Canadian coverage will find a list of merchants that already pay for order review.

Switching is small, and mostly overlap

Since March, 27 domains dropped Signifyd and run Riskified, 22 run NoFraud and 19 run Forter; going the other way, 22 left NoFraud, 19 left Forter and 10 left Riskified for Signifyd. These are domains, and many ran both tools for a while. 9 of the 27 Riskified rows still run Signifyd on another hostname, and only 3 added Riskified after leaving Signifyd. 12 of the 19 Forter rows still run Forter somewhere. The rows out add up to 68 against 815 removals.

"The switching rows add up to 68 against 815 removals. Most sites that drop Signifyd show no rival on the pages we read." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: treat a recent Signifyd leaver as an open question. The new tool may sit on checkout where we can't see it, or the merchant may have gone back to its own rules. Ask.

The stack around it

In our stack table, Shopify runs on 80.66% of live Signifyd domains, BigCommerce on 4.68% and Salesforce Commerce Cloud on 3.36%. Apple Pay is on 67.45%, Shop Pay 65.71% and PayPal 63.62%. Buy-now-pay-later is thinner: Klarna Checkout 8.08%, Afterpay 7.5%, Affirm 5.36% and Sezzle 2.43%. Klaviyo runs on 47.58%, and 282 domains run both Signifyd and Attentive, about one Signifyd domain in 13.

Sales signal: BNPL is the gap. With Klarna Checkout on 8.08% and Afterpay on 7.5%, most Signifyd merchants don't show a pay-later option on the pages we read, and they already trust a vendor to carry order risk.

What it costs

Signifyd's pricing page, checked on 10 October 2026, lists no prices. It says Signifyd charges a percentage of the order total when an order is approved, with no charge when an order is declined for fraud, and that the rate depends on products, vertical, order volume and average ticket. The guarantee is configurable, from fraud-only cover to a total chargeback liability shift.

Sales signal: a per-approved-order fee grows with sales. Merchants with rising order volume have the most reason to renegotiate, which is the opening a rival needs.

Key takeaways

1. 3,769 live domains, a floor, because many stores load the script only at checkout.

2. 9th of 32 in Fraud Prevention. Among order-fraud vendors it trails Sift and NoFraud, and Forter's count is dominated by one ordering platform.

3. Shopify on 80.66% of domains, with enterprise names such as Philips and Abercrombie & Fitch.

4. Canada is the second market, with 124 matched companies to the UK's 90.

5. 815 removals since March, and only 68 switching rows out.
