If suspicious orders, chargebacks and manual reviews are starting to consume more time, you are not late to the problem. Most stores begin with the screening included in their payment platform, then discover that fraud prevention becomes a separate operating discipline as order volume, markets and payment methods expand. This guide explains what a dedicated fraud platform adds, compares four credible options, and gives you a practical test for deciding whether your store needs one yet.
In short: Signifyd is the best dedicated ecommerce fraud tool for established merchants that can justify custom pricing and want a financial guarantee on approved orders. Stripe Radar is the better first step for smaller stores already using Stripe, because basic screening is included with standard processing and the advanced controls remain inexpensive.
NTK Score: Signifyd
Our editorial assessment of how confidently we'd recommend this to a small business, scored across the five dimensions shown below: relevance, effort, adoption, commercial value and trust. It is based on desk research (vendor documentation, pricing pages and public sources), not hands-on testing, and it is not a popularity score or a compliance audit.
The vendor addresses ecommerce fraud, false declines and chargebacks with mature automation and guarantees, but its enterprise-heavy positioning weakens the fit for low-volume retailers.

When built-in fraud screening stops being enough
A dedicated fraud tool becomes worth considering when the total cost of fraud is larger than the chargebacks visible in your payment dashboard. An ecommerce operations manager may start with the processor's default screening and manually inspect every flagged order. As chargebacks rise, that same manager can end up choosing between two bad outcomes: approving risky orders or declining legitimate customers because the available evidence is too thin.
The better after-state is not simply blocking more transactions. A dedicated risk layer evaluates order, device, identity and behaviour signals, gives the team a clearer reason for a decision, reduces avoidable manual review, and helps assemble evidence when a dispute arrives. The commercial goal is to reduce fraud without turning good customers away.
False declines matter because a blocked legitimate order is lost revenue. Processor-native screening is often adequate for a young store with a simple checkout and low dispute volume. Dedicated platforms make more sense for high-value goods, cross-border sales, repeated account attacks or a contractual guarantee against qualifying fraud losses.
The products solve different problems. Signifyd and Riskified focus on ecommerce decisions and chargeback liability, Sift supports broader payment and account risk operations, and Stripe Radar is the lowest-friction choice when Stripe already processes the payments.
Data and privacy flag: All four services send order, payment, device, identity, account or behavioural signals to vendor-hosted systems under the vendor's service terms and data-processing agreement. Before rollout, confirm hosting regions, retention, subprocessors, cross-border transfers and whether the vendor may use merchant data to improve its network models.
How we evaluated the tools
We judged these tools on business outcomes, not the number of technical claims on a product page. Criteria included decision quality, false-decline control, chargeback liability, explainability, review workflow, integrations, data governance, support and pricing clarity.
We also separated screening from a financial guarantee. Pricing and product facts were checked against official vendor pages on 27 July 2026, and custom-quote vendors were not ranked by price without a merchant-specific proposal.

1. Signifyd: best dedicated ecommerce fraud tool
Signifyd is the strongest overall choice when an ecommerce merchant wants fraud decisions and a contractual financial outcome in the same service. Its pricing is based on a percentage of approved order value, with the exact rate influenced by products selected, vertical, volume and average order value. Signifyd states that orders declined for fraud are not charged, which aligns its fee with transactions the merchant can fulfil.
The main advantage is the configurable guarantee. Depending on the contract, cover can range from fraud-related chargebacks to a broader liability shift. Signifyd also lists prebuilt integrations for Shopify, BigCommerce, Adobe Commerce, Salesforce Commerce Cloud, VTEX and others, along with payment connections including Stripe, Adyen, PayPal, Square and Worldpay.
The limitation is buying friction. There is no public rate that lets a smaller merchant estimate monthly spend before talking to sales, and the value depends on the exclusions and evidence rules inside the actual guarantee. Ask for a quote that separates software, guarantee scope, implementation, minimum commitment and chargeback recovery services. Read our full Signifyd review for the complete breakdown.
| Best for | Established ecommerce merchants prioritising approval rates, automation and chargeback liability cover |
|---|---|
| Pricing | Custom percentage of approved order value; checked 2026-07-27 |
| Guarantee | Configurable, from fraud-only protection to broader chargeback liability shift |
| Integrations | Major commerce platforms, payment providers, REST APIs, webhooks and SDKs |
| Data destination | Order, session, device, behavioural and chargeback data is processed in Signifyd's service under contract and privacy terms |
Pros
- Combines automated fraud decisions with a contractual financial guarantee
- Broad ecommerce-platform and payment-provider integration coverage
- No fee on orders declined for fraud under the published pricing model
- Expert re-review path for declined orders
Cons
- No public rate or self-serve plan
- Guarantee value depends on negotiated scope and exclusions
- Likely more solution than a low-volume store needs
2. Riskified: best for complex global commerce risk
Riskified is the better fit when fraud is only one part of a wider ecommerce abuse problem. Its platform extends beyond payment decisions into account security, returns and policy abuse, payment optimisation and dispute management. That breadth matters for a large retailer dealing with account takeover, reseller behaviour, false item-not-received claims and chargebacks across several markets.
Chargeback Guarantee makes real-time decisions and places qualifying approved orders under a contractual guarantee. Riskified's own billing documentation refers to approved-order fees and a possible contractual minimum monthly fee, so the commercial model needs close review rather than a simple per-seat comparison. Its trust centre publishes a DPA, subprocessor information and current security and compliance documents, which is useful during vendor due diligence.
The drawback is fit. A smaller merchant that only needs stronger payment screening can end up buying into an enterprise operating model, a sales process and a product family broader than the immediate problem. Riskified belongs on the shortlist when the merchant has enough volume and complexity to use the wider platform, not simply because it offers more modules. Read our full Riskified review for the complete breakdown.
| Best for | Large or complex ecommerce merchants managing fraud, account risk, policy abuse and disputes |
|---|---|
| Pricing | Custom contract; approved-order fees and possible contractual monthly minimums |
| Guarantee | Chargeback Guarantee for qualifying approved orders under negotiated terms |
| Platform scope | Chargeback Guarantee, Policy Protect, Account Secure, Dispute Resolve and payment optimisation |
| Data destination | Device, behavioural, order and chargeback data is processed by Riskified under its service agreement and DPA |
Pros
- Covers more of the ecommerce customer journey than payment fraud alone
- Chargeback guarantee aligns risk decisions with a financial outcome
- Published trust centre, DPA and subprocessor information
- Strong fit for multi-market and high-volume operations
Cons
- No public list price
- Contract may include minimum monthly commitments
- Broad platform and enterprise sales process may be excessive for smaller stores
3. Sift: best for analyst-led fraud operations
Sift is the best option here for a business building a broader internal fraud operation rather than outsourcing the decision and liability. Its payment-fraud product uses real-time risk decisions, a user-level view and a large shared data network. The Sift Console supports investigations and manual review, while the Sift Score API can add external risk context to a merchant's own decision engine.
That makes Sift attractive to a marketplace, subscription platform or ecommerce business where account creation, account takeover and payment abuse interact. A fraud analyst can investigate linked behaviours instead of treating each card transaction as an isolated event. It is also the strongest choice among these four when the business wants to retain its own rules, workflows and final control.
The trade-off is operational responsibility. Sift provides intelligence and tooling, but its current payment-fraud page does not present the same default financial liability shift promoted by Signifyd or Riskified. A merchant needs people who can tune controls, review cases, measure false positives and own the resulting decisions, and pricing still requires a sales quote.
| Best for | Businesses with fraud analysts or an internal risk engine covering payments, accounts and abuse |
|---|---|
| Pricing | Custom quote; no current public list price found as of 2026-07-27 |
| Decision tools | Real-time risk decisions, Sift Console, manual review and Sift Score API |
| Wider coverage | Payment fraud, account takeover, fake accounts and other digital abuse |
| Data destination | Transaction, account, device and behavioural signals are processed in Sift's platform under contract and privacy terms |
Pros
- Broad view of payment, account and abuse risk
- Useful analyst console and investigation workflow
- API can supplement an internally built risk engine
- Strong fit for marketplaces and subscription businesses
Cons
- No public pricing
- Requires more fraud-operations maturity than a simple plug-in tool
- No equivalent default chargeback liability shift advertised on the payment-fraud product page
4. Stripe Radar: best first step for Stripe merchants
Stripe Radar is the practical default for a smaller ecommerce store already processing payments through Stripe. Stripe has restructured Radar's pricing since this guide was first checked: Standard now offers a choice between a $10/month subscription (includes 200 screened transactions, then $0.05 per additional screened transaction) or pure pay-as-you-go at $0.05 per screened transaction with no recurring fee. Plus starts from $14/month and Pro from $20/month, both also with a pay-as-you-go alternative (their exact per-transaction pay-as-you-go rates were not confirmed in this check). All figures confirmed live 25 August 2026. The separate "Radar for Fraud Teams" plan referenced in older documentation has been folded into Radar Pro, which now covers advanced fraud and customer-abuse protection, bot detection and dynamic risk thresholds.
Radar's limitation is that screening and chargeback liability are not the same product. Stripe offers separate dispute-management and protection options, with pricing and eligibility varying by market and account. Radar is still the right place to start when Stripe already has the transaction data, but merchants seeking a broad contractual liability shift should compare the dedicated platforms.
| Best for | Small and mid-sized stores already using Stripe Payments |
|---|---|
| Basic pricing | Radar Standard: $10/month subscription (200 screened transactions included, then $0.05 per additional transaction), or pure pay-as-you-go at $0.05 per screened transaction; checked live 25 Aug 2026 |
| Advanced tier pricing | Radar Plus from $14/month USD, Radar Pro from $20/month USD, each also with a pay-as-you-go option (exact per-transaction rate not confirmed); checked live 25 Aug 2026. Stripe has retired the older per-transaction-only "Radar for Fraud Teams" pricing referenced in prior checks -- that capability set is now part of Radar Pro. |
| Controls | Rules, lists, thresholds, risk scores, manual reviews, analytics and 3D Secure |
| Data destination | Payment, account, device and behavioural data is evaluated within Stripe's payment and Radar environment under Stripe terms |
Pros
- Built into Stripe with little or no extra integration work
- Clear public pricing in supported markets
- Low-cost advanced tier for standard-pricing accounts
- Strong rules, review and authentication controls
Cons
- Best economics and workflow are tied to Stripe
- Radar screening alone is not a broad chargeback guarantee
- Local prices and dispute-product availability vary by country
Our top pick and the exception that matters
Signifyd is our top dedicated fraud-detection choice because it combines ecommerce decisioning, broad integrations and configurable financial protection in one commercial proposition. For an established merchant with meaningful chargeback losses and manual review overhead, that is easier to value than a risk score alone. The quote should still be tested against the merchant's own fraud losses, false declines, staff time and guarantee exclusions.
The exception is important: many smaller Stripe merchants should choose Radar first. It uses data already available inside the payment flow, has transparent transaction pricing, and may be included at the basic level. Moving straight to a custom enterprise contract before tuning the controls already available in the processor is usually unnecessary.
Riskified moves ahead of Signifyd when the real problem includes policy abuse, account risk and disputes across a large global operation. Sift moves ahead when an internal fraud team wants the data, investigation tools and API flexibility to run its own decisioning programme.
What to consider before choosing
Start with the cost of the problem, not a vendor feature list. Add fraudulent chargebacks, dispute fees, fulfilment and shipping losses, manual-review hours, customer-service time and estimated legitimate orders declined. Compare that monthly figure with the quoted platform cost and the portion of loss the contract actually covers.
A guarantee is only valuable when its definitions match the disputes your store receives. Ask which reason codes qualify, whether friendly fraud is included, what evidence must be supplied, how quickly claims are paid, and which order changes or fulfilment practices void cover. Request a sample claim workflow before signing.
Integration quality determines whether the tool removes work or creates another queue. Confirm how decisions return to the commerce platform, whether approved orders flow to fulfilment, how refunds and edits are handled, and how chargebacks feed back into the model. A connector alone does not prove the full order lifecycle is covered.
Decide who owns the system after launch. A guaranteed-decision product can reduce review work, while Sift or Radar for Fraud Teams offers more control but requires someone to monitor rules, false positives and seasonal changes.
Global stores should treat data terms as part of the buying decision. Fraud detection relies on detailed transaction, identity, device and behaviour signals, so ask where that information is processed, which entities receive it, how long it is retained and how customer privacy requests are supported in each market. Review the DPA, security documents and subprocessor list rather than relying on a general security badge.
For a repeatable vendor screen, use the Need to Know AI risk assessment guide. The wider ecommerce software hub helps place fraud prevention alongside support, marketing and store operations rather than treating it as an isolated purchase.
When ordinary payment controls are enough
You do not need a separate fraud platform simply because one exists. If chargebacks are rare and review volume is manageable, first configure the processor's rules, authentication, address checks, velocity limits and review process. Better checkout data and a consistent fulfilment policy may solve the problem without another vendor.
Revisit the decision when the current setup regularly blocks good customers, misses costly fraud or consumes enough staff time for a specialist platform to show clear payback.

What is the difference between fraud screening and a chargeback guarantee?
Fraud screening scores or blocks a transaction, while a chargeback guarantee can reimburse qualifying losses on orders the vendor approved. The guarantee always depends on contract definitions, exclusions and claim procedures, so compare the legal scope rather than the marketing label.
When should an ecommerce store move beyond its payment processor's built-in fraud tools?
Move beyond built-in controls when chargeback losses, false declines and manual review time are consistently material. A dedicated platform is easier to justify when the store sells high-value goods, operates across several markets or needs contractual liability cover.
Which fraud tool is best for a small Shopify store?
The best first option usually depends on the payment processor. A Shopify store using Stripe should tune Radar before buying an enterprise platform, while a higher-volume merchant wanting a guarantee should compare Signifyd and Riskified quotes against its actual losses.
Can AI fraud tools reduce false declines?
They can, because they use more context than a simple block rule and can distinguish risky patterns from legitimate customer behaviour. Results depend on the data collected, the merchant's configuration and whether the team measures approved fraud and declined good orders together.
Do fraud-detection tools eliminate manual review?
Some guaranteed decision products can automate most approve-or-decline work, but manual review does not disappear in every setup. Teams may still review borderline cases, resubmit declined orders, investigate account abuse or prepare evidence for disputes.
What should I ask for in a fraud-platform quote?
Ask for the pricing unit, minimum commitment, implementation cost, contract term, support level, guarantee scope, exclusions and claim timeline. Give the vendor your order volume, average order value, fraud rate, chargeback mix, false-decline estimate and manual-review hours so the proposal can be tested against a real baseline.

The April 2025 terms permit customer data to improve machine-learning models and commingle it with other customers' data, while stating raw customer data is not exposed to other customers: https://sift.com/wp-content/uploads/2025/07/Sift-Terms-of-Service_041525.pdf
Who this matters to: Retailers whose privacy notices, customer contracts or internal policies restrict cross-customer model improvement: Deployment may conflict with existing data-use representations even though other customers do not receive the retailer's raw data.
What to do: Have privacy counsel or the responsible governance owner review the DPA, permitted purposes, opt-out availability and required customer disclosures.

The vendor's Service Privacy Notice identifies processing in the United States, Ukraine and other countries, while retention is determined case by case rather than through a public fixed schedule: https://sift.com/wp-content/uploads/2025/05/Service-Privacy-Notice-230608.pdf
Who this matters to: Retailers with contractual data-location requirements or strict retention limits: The standard service may not satisfy a retailer's location or deletion timetable without negotiated safeguards.
What to do: Request hosting details, subprocessors, transfer safeguards, backup-deletion timing and a contractual retention schedule before sending production data.
Changes our recommendation for this audience: see verdict notes.
Standard terms make fees non-cancelable and non-refundable, prevent unused minimum fees rolling forward, and automatically renew subscriptions for 12 months unless notice is given at least 60 days before expiry: https://sift.com/wp-content/uploads/2025/07/Sift-Terms-of-Service_041525.pdf
Who this matters to: Cash-constrained or seasonal retailers with uncertain transaction volumes: A retailer can remain committed to unused capacity or another annual term even if transaction volume or fraud exposure falls.
What to do: Negotiate cancellation, renewal reminders, volume true-downs, price caps and a short initial term in the order form.
Changes our recommendation for this audience: see verdict notes.
Sift publicly announced SOC 2 Type 2 completion and renewal in 2016 and 2017, but desk research did not locate a current report or public audit period: https://sift.com/blog/sift-science-soc-2-compliant/ and https://sift.com/blog/soc-2-type-2-renewed/
Who this matters to: Retailers requiring current independent assurance before sharing transaction and customer data: Procurement cannot confirm from public material whether present systems and services remain within an independently tested control scope.
What to do: Request the latest SOC 2 Type 2 report, bridge letter, penetration-test summary and remediation status under NDA.
Recommendation depends on who's asking
Small retailers without backend engineering capacity or a dedicated fraud operator: The retailer may incur integration-service costs and lack the staff needed to tune rules, label outcomes and operate review queues effectively.
Retailers whose privacy notices, customer contracts or internal policies restrict cross-customer model improvement: Deployment may conflict with existing data-use representations even though other customers do not receive the retailer's raw data.
Retailers with contractual data-location requirements or strict retention limits: The standard service may not satisfy a retailer's location or deletion timetable without negotiated safeguards.
Cash-constrained or seasonal retailers with uncertain transaction volumes: A retailer can remain committed to unused capacity or another annual term even if transaction volume or fraud exposure falls.
NTK Score: Stripe Radar
Our editorial assessment of how confidently we'd recommend this to a small business, scored across the five dimensions shown below: relevance, effort, adoption, commercial value and trust. It is based on desk research (vendor documentation, pricing pages and public sources), not hands-on testing, and it is not a popularity score or a compliance audit.
The vendor’s network-level risk scoring, default controls and broad payment-method coverage closely fit online retail fraud, but advanced tuning and abuse controls sit above the entry tier.
Tier 2 · Stripe Radar pricing and feature comparison: https://stripe.com/us/radar/pricing ; Stripe risk evaluation documentation: https://docs.stripe.com/radar/risk-evaluation ; G2 Radar reviews: https://www.g2.com/products/stripe-radar/reviews · Confidence: Moderate
Radar Lite is built into standard Stripe processing with no extra integration, while custom rules, backtesting and non-Stripe coverage require configuration, suitable payment data and potentially developer involvement.
Tier 2 · Stripe Radar pricing and integration claims: https://stripe.com/us/radar/pricing ; Stripe testing documentation: https://docs.stripe.com/radar/testing ; Stripe multi-processor documentation: https://docs.stripe.com/radar/multiprocessor ; G2 Radar reviews: https://www.g2.com/products/stripe-radar/reviews · Confidence: Moderate
The dashboard, risk levels, manual reviews and extensive documentation support routine use, but false-positive tuning requires fraud judgement and third-party feedback raises concerns about escalated support quality.
Tier 2 · Stripe risk-insights documentation: https://docs.stripe.com/radar/reviews/risk-insights ; Stripe rules documentation: https://docs.stripe.com/radar/rules ; G2 Radar reviews: https://www.g2.com/products/stripe-radar/reviews ; broader Stripe support signal: https://www.trustpilot.com/review/stripe.com · Confidence: Moderate
Included Radar Lite and low starting subscriptions can offer strong loss-prevention value, but regional price differences, a changing plan structure and usage-based charges make global cost forecasting less straightforward.
Tier 2 · Current US pricing: https://stripe.com/us/radar/pricing ; current UK pricing: https://stripe.com/gb/radar/pricing ; Portugal pricing showing the older plan structure: https://stripe.com/en-pt/radar/pricing ; Stripe Radar documentation: https://docs.stripe.com/radar · Confidence: Moderate
Stripe appears highly stable and publishes detailed model-training, opt-out and security information, but recent pricing changes and weak broader merchant-support sentiment justify meaningful deductions.
Tier 2 · Stripe 2025 company update: https://stripe.com/newsroom/news/stripe-2025-update ; Stripe Privacy Center: https://stripe.com/gb/legal/privacy-center ; Stripe security documentation: https://docs.stripe.com/security ; Stripe risk-evaluation opt-out documentation: https://docs.stripe.com/radar/risk-evaluation ; official support information: https://support.stripe.com/questions/submit-a-complaint ; Trustpilot Stripe reviews: https://www.trustpilot.com/review/stripe.com · Confidence: Moderate
What to know before you buy
These don't change the score above: they're conditions worth understanding for specific readers before you commit.
Stripe's US page lists Standard, Plus and Pro subscriptions from US$10, US$14 and US$20 monthly, while https://stripe.com/en-pt/radar/pricing still displays the older per-transaction machine-learning and Fraud Teams plans.
Who this matters to: Merchants comparing costs across countries or operating multiple regional Stripe accounts: Plan names, included capabilities and effective screening costs may differ by account country or change as the new structure rolls out.
What to do: Check the pricing page for the account's country and confirm current rates inside the Stripe Dashboard before budgeting.
Stripe documents non-Stripe payment scoring at https://docs.stripe.com/radar/multiprocessor, but it requires tokenized card payment methods, Radar Session tokens, customer email collection and API integration.
Who this matters to: Retailers using another processor or a mixed-gateway payment stack: These merchants lose Radar's simplest built-in deployment path and may need developer work, additional data collection and separately confirmed pricing.
What to do: Request a scoped quote and run a technical pilot using representative checkout traffic before committing.
Stripe states at https://docs.stripe.com/radar/reviews/risk-insights that risk-insights data is stored for up to six months, although complete transaction-history exports are separately available.
Who this matters to: Businesses needing long-term fraud-factor analysis or historical investigation records: Detailed model explanations for older payments may no longer be available in the risk-insights interface.
What to do: Export necessary transaction and investigation records on a regular schedule under an appropriate data-retention policy.
Stripe advertises 24-hour support at https://support.stripe.com/questions/submit-a-complaint, but broader Stripe feedback at https://www.trustpilot.com/review/stripe.com repeatedly alleges slow or ineffective escalations; this signal is not Radar-specific.
Who this matters to: Businesses requiring urgent human assistance during fraud spikes or false-positive incidents: Access to live support may not guarantee rapid specialist resolution when legitimate orders are being blocked or fraud controls require urgent adjustment.
What to do: Document an internal fraud-response process and validate available support and escalation channels before relying on Radar for high-risk sales periods.
