Best Fraud Detection Software in 2026: 9 Companies Compared

#1

Sift

Best for: Mid-market to enterprise wanting full-lifecycle coverage

Visit sift.com

Sift is the scoring-model leader: a machine learning platform that scores risk across the whole account lifecycle, from fake signups to payment fraud to content abuse. Its network processes an enormous volume of events, which feeds models that flag account takeover, promo abuse and payment fraud in real time. You keep the final decision, which appeals to companies with their own fraud teams and appetite for control.

The cost of that control is operational. Pricing is entirely quote-based, built on transaction volume, modules and service level, with no free tier or trial. Reviewers praise the engine and flag the tuning work: configuring rules, calibrating models and explaining scores to stakeholders takes dedicated staff. Sift fits mid-market and enterprise teams that want intelligence without outsourcing the risk decision. Small merchants will find simpler tools cheaper and easier.

#2

Forter

Best for: Enterprises wanting approval-rate and chargeback guarantees

Visit forter.com

Forter sells outcomes, not software. Its platform returns real-time approve/decline decisions backed by a chargeback guarantee, and its identity graph draws on billions of identities to recognize legitimate customers other systems would decline. The pitch is approval-rate economics: every false decline is lost revenue, and Forter's models are tuned to recover it.

Pricing is quote-only and scales with your GMV, which makes it an enterprise conversation from the start. Third-party estimates put mid-market annual costs in the tens to hundreds of thousands, but Forter publishes nothing. If your priority is transferring fraud liability while squeezing more approvals from the same traffic, Forter is the strongest guarantee play. If you want to keep decisions in-house, look at Sift or Kount instead.

#3

Riskified

Best for: Large merchants wanting a guaranteed approve/decline decision

Visit riskified.com

Riskified is the public-company option in fraud guarantees: it approves or declines each order and covers fraud chargebacks on the ones it approves. Being NYSE-listed gives buyers financial transparency most competitors cannot match, and the platform has grown beyond checkout fraud into policy abuse, account takeover and chargeback representment.

The commercial model is a percentage of approved order value plus an annual minimum, quoted per merchant. That means your fraud-prevention bill grows with your revenue, which is fine when fraud losses fall faster, but you should model it against your actual fraud rate first. The guarantee also excludes friendly-fraud categories like item-not-received disputes. Riskified suits large merchants that want a financially solid partner to carry fraud risk.

#4

Signifyd

Best for: Mid-market merchants wanting 100% chargeback protection

Visit signifyd.com

Signifyd pioneered the guaranteed fraud protection model for mid-market ecommerce: automated approve, decline or review decisions on every order, with the company reimbursing fraud chargebacks on orders it approved. Decision orchestration routes borderline orders to manual review queues, and the system learns from outcomes across its merchant network.

Pricing is a percentage of order value, quoted per merchant, with no published tiers. Reviewers consistently rate the fraud prevention highly and the value as strong against the cost of unmanaged chargebacks, while noting the fee structure gets expensive at scale. Signifyd fits mid-market retailers that want to outsource fraud decisions entirely with a financial backstop. Merchants that want to keep the decision in-house should compare Sift.

#5

Kount (Equifax)

Best for: Enterprises already on Equifax identity rails

Visit kount.com

Kount, an Equifax company since 2021, brings identity data most fraud vendors cannot match. The Identity Trust Global Network scores interactions using device intelligence combined with Equifax's identity and credit data, covering payments, new accounts and logins. For companies already using Equifax for identity or credit services, vendor consolidation is a genuine argument.

Pricing is quote-only and not published anywhere, which makes Kount the hardest vendor here to benchmark before a sales conversation. Third-party estimates consistently place it at the premium end. Kount fits enterprises with serious identity-fraud exposure and existing Equifax relationships. Everyone else should get at least one published-price quote, from SEON or Fingerprint, before engaging.

#6

SEON

Best for: SMBs wanting published pricing and fast deployment

Visit seon.io

SEON is the transparency play in a quote-heavy market. Its published Shopify app tiers start at $299 a month for 1,000 order checks with self-serve onboarding, stepping to $599 for 3,000 checks, with custom enterprise plans above that. The platform combines digital footprinting, email and phone intelligence, device fingerprinting and machine learning rules in a single API that deploys in days rather than quarters.

A few caveats. The published tiers cover the Shopify app; high-volume API use is quoted. And one widely discussed 2026 review reported a steep renewal increase, so negotiate price protection into multi-year deals. SEON suits small and mid-size businesses, especially on Shopify, that want real fraud tooling with pricing they can read before talking to sales. It is the most accessible serious option on this list.

#7

Fingerprint

Best for: Developers needing device intelligence to build their own rules

Visit fingerprint.com

Fingerprint is the developer's fraud tool: a device intelligence API that returns a stable, accurate visitor identifier from 100-plus browser and device signals, plus smart signals for bot detection, VPN use, geolocation and tampering. The free plan covers testing, Pro Plus starts at $99 a month for 20,000 web and iOS API calls (plus 500,000 Android calls), all published on Fingerprint's own pricing page with a 14-day trial.

What it does not do is decide. There are no built-in approve/decline workflows or chargeback guarantees; you feed the identifier and signals into your own rules or fraud engine. That makes it the cheapest way to add serious device intelligence to a signup flow, login page or checkout, and reviewers consistently praise the accuracy and documentation. Fingerprint fits engineering-led teams fighting fake accounts, trial abuse and account takeover. If you want decisions made for you, buy a guarantee platform instead.

#8

ClearSale

Best for: International merchants wanting human review behind the guarantee

Visit clear.sale

ClearSale is the managed-service option: automated screening backed by a large team of human fraud analysts who review suspicious orders before deciding. That human layer rescues high-value legitimate orders that pure automation would decline, which matters for international merchants where data is thin and false declines are expensive. Guarantee options reimburse qualifying fraud chargebacks on approved orders.

Pricing is custom, commonly structured as a percentage of approved orders on the performance model or a per-transaction fee with the guarantee. There are no long-term contracts on some plans, which lowers the commitment risk. ClearSale suits merchants selling internationally or in high-ticket categories where analyst judgment beats model confidence. If you want instant automated decisions, the guarantee platforms above move faster.

#9

NoFraud

Best for: Small stores wanting free screening with an optional guarantee

Visit nofraud.com

NoFraud is the SMB-friendly guarantee platform. The free-to-install screening tier runs every order through an AI decision engine with human analyst review on the small fraction held for verification, including cardholder verification calls modeled on bank protocols. Paid tiers add the chargeback guarantee: if an approved order results in a fraud chargeback, NoFraud covers it.

NoFraud's own site offers starter plans, including a free plan, for businesses processing under $50,000 a month, with custom pricing above that; its Shopify app lists guarantee tiers from $250 a month. Reviewers rate it highly on value, with several noting fraud savings far exceed the fee. NoFraud fits small and mid-size stores that want enterprise-style protection without an enterprise sales process or contract.
