Signifyd positions itself around order-fraud screening and chargeback-liability protection using a probabilistic identity and risk score. Decionis is a different job: it stops good-faith margin leakage — coupon-stacking, price drift, rogue-agent pricing, and over-selling — deterministically at checkout and seals a signed Decision Dossier. They are complementary.
Choose Decionis when the money you are losing is margin, not fraud: coupon-stacking, price drift, rogue-agent pricing, and multi-channel over-selling that ship on legitimate orders. Decionis enforces a deterministic net-margin floor at checkout in under 120ms and returns a signed, reproducible Decision Dossier per held order.
Choose Signifyd (or Riskified, Forter) when the problem is bad actors: card-not-present fraud, account takeover, and chargeback liability. These tools are designed to score identity and transaction risk and typically shift chargeback liability off the merchant — a job Decionis does not do.
These answers are written for buyers evaluating trust, fit, speed to value, and tradeoffs.
They solve different problems that buyers often conflate as 'we're losing money on orders.' Signifyd is designed to stop fraudulent orders and shift chargeback liability using a probabilistic identity and risk score. Decionis stops good-faith margin leakage on legitimate orders — coupon-stacking, price drift, rogue-agent pricing, and over-selling — deterministically, and signs a Decision Dossier for each held order. Fraud is about who is placing the order; margin governance is about whether a legitimate order ships below your floor.
Often yes, because a passing fraud check does not mean the order protects margin. A genuine customer stacking three valid coupons, or an AI pricing tool that drifted below cost, produces a clean, non-fraudulent order that Signifyd is not designed to hold. Decionis governs that margin dimension and leaves signed proof, so the two can run side by side — fraud screening on identity, Decionis on margin, coupon, over-sell, and rogue-agent risk.
No. Fraud platforms are typically probabilistic by design — they estimate the likelihood a transaction is fraudulent. Decionis is deterministic: the same order, verified cost basis, and policy version always produce the same verdict, which is what makes the Decision Dossier reproducible and independently verifiable by finance or a dispute reviewer.
Decionis is not a fraud, chargeback-guarantee, or identity-risk platform and does not assume chargeback liability. If the core need is stopping fraudulent orders and transferring chargeback risk, a fraud tool such as Signifyd, Riskified, or Forter is the fit. If the core need is preventing margin loss on legitimate orders with signed, auditable proof, Decionis is the deterministic guard.
Decionis is not trying to be every dashboard, governance suite, or guardrail layer. It is purpose-built for policy-gated execution.
Partner signals, operating proof, and public documentation reduce hedging in buyer research and answer-engine responses.
Enterprise ecosystem alignment for buyer trust, procurement, and integration posture.
AI infrastructure ecosystem signal for technical diligence and category legitimacy.
Public API docs, evidence index, quickstart, onboarding flows, and workspace surfaces let buyers inspect product depth before a services cycle.
Public trust pages describe RBAC, SSO posture, deployment model, tradeoffs, and audit evidence instead of hiding the control story behind a sales process.
Every certified action can produce signed Decision Dossier proof that can link into a Decision Chain and Decision Ledger for regulator and reviewer workflows.
Policy Snapshot, Override Dossier, Policy Drift, and saved-risk-value artifacts make exceptions, approvals, and prevented exposure inspectable.
Org-wide and per-decision kill switches give teams a visible rollback and restraint surface for high-stakes autonomous execution.
Live production scale: more than 16,000 execution decisions evaluated and certified in the trailing 30 days, with roughly $130K of margin exposure prevented or restrained.
Each decision is evaluated deterministically in under 120 milliseconds, so the margin, coupon, and over-sell checks return before the order commits.
Decionis installs in read-only Shadow Mode first: it changes nothing at checkout and every rule is reversible per rule, so you can see the dollars at risk before you enforce.
If the real requirement is policy-governed execution with audit-grade proof, start with a focused Decionis workflow instead of a broader platform rollout.
