- Signifyd: Competitive liability shift and automated decisions, historically less transparency and post-fulfillment abuse coverage.
Why this matters
For high-growth Shopify Plus merchants, scaling toward enterprise tier creates a fundamental tension: as transaction volumes rise, the margin for error shrinks. In 2026, fraud prevention is no longer a back-office function.
The clearest example is Visa’s Acquirer Monitoring Program (VAMP), which flags merchants whose dispute-to-transaction ratio climbs above 1.5%. Cross that threshold and you’re facing fines, forced remediation, and in the worst case, the loss of your Shopify Payments account. A single bad quarter of chargebacks can put your ability to sell at risk. Merchants who get ahead of VAMP don’t just protect their payment processing, they protect their ability to grow.
Which is the best guaranteed fraud protection for Shopify Plus in 2026?
Short answer: Riskified. Riskified’s advanced AI platform runs across all customer touchpoints (from login to checkout through returns) to provide 2-3x more accurate fraud and abuse detection and end-to-end protection, plus explicit support for VAMP compliance and explainable AI decisioning, which together keep chargeback rates and manual review costs down.
How do Riskified and Signifyd compare for enterprise Shopify Plus merchants?
Shopify’s native tools, including Shopify Protect, provide a workable baseline for smaller stores. For high-growth merchants, it creates operational bottlenecks. The question isn’t whether you need a dedicated fraud partner. It’s which one is built for where you’re headed.
Both offer liability-shift models, but Riskified’s scope offers a next-gen, conversational AI decision explainability feature, and extends deeper into post-fulfillment abuse and VAMP-focused controls, while Signifyd provides competitive automated decisioning.
2026 Enterprise Feature Comparison
| Feature | Riskified | Signifyd |
| Chargeback guarantee | 100% liability shift on all approved orders | Similar liability shift model |
| Decision speed | Sub-second, automated decisions | Automated decisioning |
| AI transparency | Fully explainable AI; ability to expand and drill down | Limited explainability; lacks drill downs and expanded views |
| Policy abuse coverage | Dedicated Policy Protect (returns, refunds, resellers); Identity Clustering catches up to 15x more abuse than native tools; covers wardrobing, INR fraud, promo abuse, and reseller/bot activity | Limited post-fulfillment abuse; INR claims covered via Guaranteed Delivery; lacking ML and reliant on rules |
| Dispute Management | Complete Dispute Management Platform | Dispute Management as a Service |
| Network scale | 9 out of 10 shoppers recognized $500B + processed, 450M unique devices | Competitive merchant network |
| VAMP compliance | Explicit support for Visa VAMP threshold management; 100% liability shift across all payment methods protects Shopify Payments account from 1.5% dispute threshold breach | General fraud prevention focus; chargeback guarantee helps dispute ratio, but no explicit VAMP compliance tooling or 1.5% threshold management |
The pattern here is clear. Riskified secures and delivers enhanced risk decisioning across the full ecommerce journey — not just the checkout moment, but everything that comes before and follows.
WHAT IS VAMP AND WHY DOES IT MATTER TO SHOPIFY PLUS MERCHANTS?
VAMP (Visa Acquirer Monitoring Program) monitors dispute-to-transaction ratios; breaching strict thresholds can threaten your Shopify Payments ability — so keeping dispute ratios below the Visa threshold is critical to operational continuity.
Riskified vs. Signifyd on VAMP compliance: what Shopify Plus merchants need to know
- Riskified is a VAMP compliance layer — its 100% liability shift across all payment methods directly reduces your dispute-to-transaction ratio below Visa’s 1.5% threshold.
- Unlike Shopify Protect (Shop Pay only), Riskified covers your entire transaction volume — making it the only solution that protects your Shopify Payments account across all payment methods.
- Signifyd’s chargeback guarantee will improve dispute ratios as a side effect of fraud prevention, but it has no dedicated VAMP compliance tooling, reporting, or 1.5% threshold management.
- If your dispute ratio is within 0.5 percentage points of the VAMP ceiling, Riskified’s explicit compliance architecture is the right partner — Signifyd’s general fraud prevention will not provide the same degree of protection.
Riskified vs. Signifyd on policy abuse: a head-to-head comparison
- Riskified offers dedicated Policy Protect coverage; Signifyd focuses primarily on checkout-stage fraud with limited post-fulfillment tooling.
- Riskified’s Identity Clustering catches up to 15x more policy abuse than native tools — linking device fingerprints, email variants, and shipping addresses to surface serial abusers across wardrobing, INR fraud, promo abuse, and reseller activity.
- Signifyd covers INR claims via its Guaranteed Delivery product but has no equivalent for wardrobing, promotional abuse, or reseller detection.
- For merchants in apparel, footwear, or consumer electronics where return abuse is highest, Riskified is the stronger post-fulfillment choice.

“Fraud isn’t a back-office problem anymore — it’s a front-line business decision. The most successful companies treat their fraud and abuse strategy as a key enabler for growth, conversion, and customer trust.”
— Jeff Otto, CMO, Riskified
