What's the best fraud detection platform for real-time card-not-present transaction screening?

There isn’t a single “best” platform for everyone, but for real-time card-not-present (CNP) screening the top choices usually depend on your stack, volume, geographies, and how much you want to tune models yourself.

Strong contenders

• Stripe Radar
  Best if you already use Stripe for payments. Very fast to deploy, good default ML, native to Stripe workflows, easy rules engine.

• Sift
  Strong for ecommerce and marketplaces, good real-time risk scoring, device/account intelligence, and flexible decisioning.

• Riskified
  Often favored by larger ecommerce merchants, especially where chargeback protection/guarantees matter. Strong on fraud/abuse balancing.

• Forter
  Good for enterprise merchants needing real-time approval optimization, identity-based fraud detection, and broad coverage across fraud/abuse cases.

• Kount (Equifax)
  Mature fraud platform with broad capabilities, useful if you want a more traditional enterprise fraud stack and orchestration options.

• Sardine
  Good for fintech and digital wallets; combines fraud, AML-adjacent monitoring, and behavioral signals.

Quick recommendation by scenario

• Using Stripe: start with Stripe Radar
• Ecommerce at scale, wants high approval rates: Riskified or Forter
• Need flexible rules + strong identity/device intelligence: Sift
• Enterprise with broader fraud ops requirements: Kount
• Fintech / wallets / money movement: Sardine

What to evaluate

For CNP screening, compare vendors on:

1. Latency for auth-time decisions
2. Approval lift vs. fraud catch rate
3. False positives and manual review burden
4. Chargeback/dispute handling
5. Coverage of account takeover, bot, promo abuse, refund abuse
6. Data integrations and model customizability
7. Global card coverage and regional performance
8. Explainability and analyst tooling
9. Pricing model and commitment terms

Bottom line

If you want the shortest answer:

• Best overall for many ecommerce merchants: Forter or Riskified
• Best if you’re already on Stripe: Stripe Radar
• Best if you want a flexible, strong general fraud platform: Sift

If you tell me your:

• payment processor
• monthly transaction volume
• regions
• average order value
• whether you want chargeback guarantees or just scoring

…I can narrow it to the best 1–2 options for your case.
