Riskified vs Signifyd (2026)
Both sell ecommerce fraud decisions under a chargeback guarantee, so the decision is which guarantee fits and how much evidence of it you want to see. Riskified returns an approve or decline in under a second, charges only on approved orders, reimburses every fraud chargeback on an order it approved and guarantees approval rates. Adaptive Checkout adds graduated friction in place of a flat decline, and its PSD2 tooling handles the strong customer authentication exemption for European orders. Signifyd also charges only on approved orders, but lets a merchant set cover anywhere from fraud only to a total chargeback liability shift. It argues openly that an approval rate promise gives a vendor no reason to beat the target. It sells a separate platform to payment providers and lets a declined order go to a certified fraud analyst for review. Riskified is listed on the New York Stock Exchange, so what the guarantee costs it appears in audited filings. Signifyd carries SOC 2 Type II, ISO 27001 and PCI DSS Level 1, while Riskified shares no certificate.
