US fraud losses hit a record $12.5 billion in 2024, up 25% year over year, according to the FTC, and the methods are getting harder to catch. Rule-based systems that worked a decade ago miss synthetic identities, account takeover and AI-cloned voices that adapt faster than any static ruleset. AI fraud detection software fills that gap by scoring behavior, devices, transactions and now voice in real time.
This guide ranks nine AI fraud detection platforms across payments, banking, ecommerce and the fast-growing voice and call-center channel.
We weighted each on detection approach, real-time scoring, explainability and best-fit use case. Because fraud now moves across channels, we have included both broad transaction-monitoring platforms and voice-fraud specialists so you can match the tool to where you are actually getting hit.
1. Velma by Modulate
Velma by Modulate leads this list for the voice channel, which transaction monitoring and call metadata routinely miss. Velma is a voice-native AI platform that detects fraud happening live inside the conversation: synthetic and cloned voices, voice mismatch against a known account holder, scripted or rehearsed speech, emotional incongruence and account-takeover attempts. It is ranked number one on Hugging Face’s Speech Deepfake Arena leaderboard and states a 1.1% Equal Error Rate, or 98.9% accuracy.
What makes it useful for fraud teams rather than just researchers is explainability and timing. Velma monitors the whole call continuously, re-scoring every couple of seconds so it catches a mid-call switch from a real voice to an AI clone, and it surfaces the underlying signals tied back to the source audio so analysts can defend a decision in an audit or dispute.
It needs only two to three seconds of audio, returns probability scores rather than black-box verdicts and integrates with Five9, Genesys, Zendesk, Zoom and Teams. Pricing starts at $0.25 per hour and the platform is ISO 27001 certified.
Best for: banks, insurers, telecom and contact centers defending high-stakes voice channels against deepfake and social-engineering fraud.
2. Feedzai
Feedzai is an AI-native financial-crime platform built for banks. It scores risk in real time across every channel and payment rail, stays typology-agnostic across card fraud, account takeover, synthetic identity and scams, and pairs pre-trained machine-learning models with explainable Whitebox AI. Its Feedzai IQ network intelligence claims significant lifts in fraud caught.
Best for: banks and payment providers needing combined fraud and AML coverage.
3. Pindrop
Pindrop brings voice security to the fraud stack, analyzing more than 250 vocal characteristics with patented Phoneprinting and Deep Voice biometrics. Its products span deepfake detection, passive authentication and real-time fraud scoring, and it reports 99% detection accuracy across billions of calls.
Best for: call centers and IVR systems defending against caller fraud.
4. NICE Actimize
NICE Actimize is an enterprise financial-crime platform covering fraud, AML and trade surveillance. Its AI delivers real-time detection across web, mobile and payments, with strong coverage of application and onboarding fraud including synthetic identity and mule accounts, plus centralized case management.
Best for: large multi-channel banks and financial institutions.
5. Featurespace
Featurespace, now a Visa solution following its December 2024 acquisition, is built on Adaptive Behavioral Analytics. Its ARIC Risk Hub analyzes up to 500 behavioral variables in under 50 milliseconds against each customer’s long-term behavior, protecting roughly 500 million consumers across more than 100 billion payment events a year.
Best for: bank and card payments fraud and transaction monitoring.
6. Sift
Sift is a digital-trust and decisioning platform for online commerce. It scores risk in real time across the full user session, drawing on identity-trust signals to cover payment fraud, account takeover and content abuse from a single platform.
Best for: ecommerce and marketplace operators.
7. Signifyd
Signifyd protects ecommerce checkout with machine-learning risk scoring backed by a large commerce network. Its differentiator is a financial guarantee: Signifyd assumes chargeback liability on orders it approves, shifting that risk off the merchant.
Best for: online retailers focused on chargeback protection.
8. SEON
SEON is an API-first, developer-friendly platform built on digital footprinting. It enriches email and phone intelligence, device fingerprinting and IP signals into more than 50 risk signals, with modular scoring at onboarding, account creation and transaction.
Best for: fintechs, digital lenders and online businesses wanting flexible, fast integration.
9. DataVisor
DataVisor is known for unsupervised machine learning that catches novel fraud without predefined rules. It combines behavioral and device intelligence to detect account takeover and synthetic identity, with adaptive scoring and case management built for high-volume digital channels.
Best for: high-volume mobile and web channels in banking and fintech.
How to choose AI fraud detection software
Begin with your fraud surface. If losses concentrate in card-not-present payments, a transaction-monitoring engine like Feedzai, Featurespace or NICE Actimize belongs at the center of your stack. If the attacks come through the contact center, voice biometrics and deepfake detection from Velma or Pindrop address a channel those payment engines cannot see. Many enterprises now run both, because fraud rarely stays in one lane.
Weight explainability heavily. Regulators and dispute processes increasingly require a clear reason for a decision, so a black-box risk score is a liability. Platforms that expose the signals behind a flag, whether that is Feedzai’s Whitebox AI or Velma tying a flag back to the source audio, save analyst time and survive scrutiny. Real-time scoring is the other non-negotiable, since a decision that arrives after the transaction clears or the call ends is worthless.
The threat is scaling faster than budgets. Deloitte projects generative AI fraud losses reaching $40 billion by 2027, and the fraud detection and prevention market is projected to grow from $32.0 billion in 2025 to $65.68 billion by 2030 at a 15.5% CAGR, per MarketsandMarkets. Account takeover alone cost US adults around $15.6 billion in 2024. Choose a platform that covers your highest-loss channel first, then expand coverage as the threats move.
FAQs
- What is AI fraud detection software? AI fraud detection software uses machine learning to identify fraudulent activity in real time by analyzing transactions, user behavior, device signals and increasingly voice. Unlike static rules, AI models adapt to new fraud patterns, which is essential as attacks evolve.
- How is AI fraud detection different from rule-based systems? Rule-based systems flag activity that matches predefined conditions and miss anything novel. AI models learn from behavior and can catch fraud they have never seen before, including synthetic identities and adaptive account-takeover attempts, while typically producing fewer false positives.
- Can fraud detection software stop voice and deepfake fraud? Specialized tools can. Voice-native platforms like Velma and Pindrop detect synthetic and cloned voices, voice mismatch and social-engineering signals during a live call, covering a channel that transaction-focused fraud engines do not address.
- How much does AI fraud detection software cost? Pricing varies widely by channel and volume. Voice detection can start around $0.25 per hour of audio, while enterprise transaction-monitoring platforms are typically priced by transaction volume and quoted per deployment. Most vendors scope pricing to your specific fraud surface and call volume.
