Signifyd vs CertNode
Signifyd vs CertNode: an honest comparison for Stripe merchants
If you are shopping for chargeback help, Signifyd and CertNode solve different parts of the problem, so the right pick depends on your size and what you actually want. Signifyd stops fraud at checkout and guarantees the orders it approves, so if a guaranteed order gets charged back, Signifyd pays you back. CertNode Reflex works after a dispute lands: it builds a verifiable evidence package and submits it to Stripe for you, and you only pay when it recovers money. This page lays out both models straight, including the cases where Signifyd is the better fit.
Who Signifyd is
Signifyd is an enterprise-grade fraud prevention and chargeback guarantee platform. It scores orders at checkout in real time using machine learning and a large cross-merchant network, then backs the orders it approves with a financial guarantee that shifts fraud liability off the merchant. It serves mid-market and large retailers across many platforms, including Shopify, BigCommerce, Adobe Commerce, Salesforce Commerce Cloud, NetSuite, and custom stacks.
How their pricing works
Signifyd uses custom, quote-based pricing rather than public rates. Their pricing page describes charging a percentage of the order total when an order is approved, with no charge when an order is declined for fraud, and the rate is tailored to your vertical, order volume, average ticket, and current chargeback and decline rates. Deals typically involve a sales conversation and an annual commitment. Exact percentages are not published, so treat any specific number you see as unverified as of 2026. The core promise is a liability shift: approved orders that later turn into eligible fraud or non-fraud chargebacks are reimbursed, often within 48 hours including fees.
Choose Signifyd if
- •You want a true chargeback guarantee and liability shift, where the provider absorbs the fraud loss on approved orders instead of you.
- •You are mid-market or enterprise with the order volume to justify a percentage-of-approved-orders cost and an annual contract.
- •You want fraud prevention at checkout and a full stack (account protection, return-abuse insight, authorization optimization), not only dispute defense.
- •You are omnichannel or run on Adobe Commerce, Salesforce Commerce Cloud, BigCommerce, or NetSuite and want deep prebuilt integrations.
Choose CertNode Reflex if
- ✓You are a Stripe SMB who wants dispute defense with no monthly fee, no contract, and no sales call, installed in minutes.
- ✓You want to pay only when a dispute is actually recovered: 15% of the recovered amount ($25 minimum for new installs, capped at half the recovery) and $0 when you lose.
- ✓You want the evidence itself to be independently verifiable (ES256 signatures, RFC 3161 timestamps, Bitcoin anchoring, self-authenticating under FRE 902(13)/(14)), not just auto-compiled.
- ✓Your volume does not justify an enterprise guarantee contract, but you still want disputes fought automatically, with optional done-for-you human help ($199 rush) when you want it.
The honest note
These tools are not the same shape, and it is fair to say Signifyd may be the better choice for you. CertNode does not prevent fraud and does not guarantee or reimburse chargebacks. If you want a liability shift where the fraud loss moves off your books, that is Signifyd's model, not ours. CertNode Reflex fights the disputes that reach you and builds evidence you can verify, and it only earns when it recovers money for you. We also cannot verify Signifyd's exact pricing, since it is quoted per merchant and not public, so confirm current terms with them directly. Plenty of merchants could reasonably run both: prevention and a guarantee at the top, verifiable pay-on-win dispute defense underneath.
On Stripe? Reflex is free to install and charges 15% only when it wins a dispute ($25 minimum on new installs, never more than half the recovery), $0 on losses.
