Which AML and transaction-monitoring tool is best for a neobank?

For a neobank, the "best" Anti-Money Laundering (AML) and transaction-monitoring tool depends heavily on your growth stage, transaction velocity , and whether you operate globally or locally . Neobanks require high-throughput, API-first, real-time infrastructure rather than legacy, batch-processing bank systems.

Top solutions are tailored to digital-first, high-growth financial institutions:

1. Best for Real-Time RiskOps & Fraud + AML Fusion: Feedzai

• Best for: Hyper-scale neobanks handling massive transaction volumes with extreme velocity.
• Why it fits: Feedzai started as a gold standard for real-time payment fraud detection and evolved into unified RiskOps. If your neobank's biggest threat vector involves instant payments, account takeovers, and money mules happening at lightspeed , Feedzai’s advanced stream processing and AI models minimize false positives while keeping up with digital banking speeds.

2. Best API-First Developer & Compliance Stack: Sardine or ComplyAdvantage

• Sardine
  • Best for: Neobanks and fintechs looking to fuse device intelligence, behavior analytics, fraud prevention, and agentic AML operations into a single platform.
  • Why it fits: Highly praised by modern digital banks because it reduces alert resolution times from days to minutes using automated workflows.
• ComplyAdvantage
  • Best for: Mid-market to scaling neobanks.
  • Why it fits: Exceptional proprietary natural language processing (NLP) for real-time watchlist screening, PEPs, and adverse media . It is built specifically with modern, agile REST APIs that integrate cleanly into a fintech microservice architecture.

3. Best All-in-One Identity & Compliance Orchestration: Sumsub or Alloy

• Sumsub
  • Best for: Global neobanks needing an end-to-end stack from KYC/KYB onboarding to robust, high-precision AML transaction monitoring.
  • Why it fits: Highly modular, letting you scale compliance infrastructure as you expand into new international jurisdictions without switching vendors.
• Alloy
  • Best for: US-centric neobanks.
  • Why it fits: It shines as an identity decisioning platform . While its native transaction monitoring is lighter than legacy giants , its no-code rule builder lets compliance teams tweak onboarding and monitoring logic instantly without filing engineering tickets.

4. The Enterprise Heavyweights (If Partnered with a Sponsor Bank)

• NICE Actimize (Autonomous AML): Great if you are scaling into a Tier-1 regulated entity or are required by traditional sponsor banks to run institutional-grade compliance engines. However, it can feel bloated and slow to implement compared to native API fintech options.

To help narrow down the ideal platform, tell me:

• What is your target geography (e.g., US-only, UK/EU, or multi-jurisdiction)?
• Are you operating under your own banking license or via a sponsor bank partner?

For a neobank, my default pick today would be Unit21—especially if you want one platform covering transaction monitoring, fraud, investigations, sanctions, and regulatory reporting.

My shortlist

Why Unit21 gets my vote

A neobank typically needs more than a traditional AML rules engine. You want to correlate:

customer → device → account → transaction → counterparty → network → fraud signals

Unit21 explicitly supports this broader data model, including behavioral/device data, graph-based rules, real-time monitoring, historical backtesting and shadow-mode testing.

It's also designed specifically for neobanks and digital banks, with transaction monitoring, case management and regulatory filing in one platform.

The particularly important feature, in my view, is backtesting/shadow mode. Before changing a rule or model, you can test its impact against historical/live data rather than discovering after deployment that you've generated 10× the alerts.

When I'd choose Hawk instead

I'd lean toward Hawk if your priority is high-quality AML detection with sophisticated AI and explainability, particularly if you're operating across multiple jurisdictions. Hawk combines configurable rules, anomaly detection and AI, and supports AML, screening and fraud in a unified environment.

When I'd choose Sardine

I'd put Sardine at the top if the neobank's problem is really fraud + AML together, rather than AML monitoring in isolation. Its graph capabilities and prebuilt typologies are compelling for detecting coordinated behavior, mule networks, structuring and layering.

My ranking for a typical U.S. neobank:

1. Unit21 — best overall
2. Hawk — best AML sophistication / explainability
3. Sardine — best combined fraud + AML fintech stack

One caveat: I wouldn't select based on vendor claims around "AI" or advertised false-positive reductions. For a serious procurement, I'd run all three through the same historical transaction dataset and compare detection coverage, false-positive rate, alert-to-case conversion, investigator productivity, latency, explainability, rule deployment speed, and total cost.

If you tell me your neobank's geography (U.S./EU/UK/etc.), transaction volume, payment rails (ACH/RTP/cards/wires), and whether you need fraud as well as AML, I can give you a much more specific recommendation and a Unit21 vs Hawk vs Sardine procurement scorecard.

But the answer changes substantially depending on your jurisdictions, transaction volume, payment rails, crypto exposure, and whether you already have a fraud/KYC/sanctions stack.

If you tell me (1) country/jurisdictions, (2) monthly transaction volume, (3) consumer vs. business accounts, and (4) your existing KYC/fraud/sanctions vendors, I can give you a much more definitive Sardine vs. Unit21 vs. Feedzai comparison, including implementation effort, likely cost structure, and which one I'd buy.

The particularly important feature, in my view, is backtesting/shadow mode. Before changing a rule or model, you can test its impact against historical/live data rather than discovering after deployment that you've generated 10× the alerts.

When I'd choose Hawk instead

I'd lean toward Hawk if your priority is high-quality AML detection with sophisticated AI and explainability, particularly if you're operating across multiple jurisdictions. Hawk combines configurable rules, anomaly detection and AI, and supports AML, screening and fraud in a unified environment.

When I'd choose Sardine

There is no single "best" AML and transaction-monitoring tool for every neobank, because the ideal choice depends heavily on your growth stage, geographic footprint , and tech stack (whether you build on a Banking-as-a-Service / BaaS partner or hold your own banking license).

However, modern digital-first banks strongly favor API-first, modular RegTech platforms over legacy enterprise monoliths (like NICE Actimize or Oracle) which are often too slow and expensive to deploy for agile fintechs.

The top contenders for a neobank are categorized below by their primary strengths:

• Sumsub — Best all-in-one lifecycle platform for fast-growing neobanks. It combines KYC/KYB onboarding, biometric verification, anti-fraud, and continuous transaction monitoring in a single dashboard. It's heavily deployed across digital banking startups because it keeps conversion rates high while cutting down the headache of stitching multiple vendors together.
• Unit21 — Best for no-code rule building and orchestration . Unit21 is built specifically for modern fintechs and neobanks, allowing compliance teams to easily write custom rules, manage case workflows, and look at transaction data alongside onboarding signals without constantly bugging engineering.
• ComplyAdvantage — Best for AI-driven risk data and screening . Known for its proprietary, real-time risk database, it excels at dynamic name screening, adverse media monitoring, and instant transaction-monitoring alerts with low false-positive rates.
• Feedzai — Best for high-volume, real-time machine learning . If your neobank is processing massive transaction velocities (p2p payments, debit card swipes, instant ACH), Feedzai uses advanced AI to catch complex financial crime patterns and account takeovers at lightning speed.
• Flagright or HAWK:AI — Best AI-native, API-first engines . These newer platforms are designed for agile developer teams that want hyper-fast API integrations, transparent pricing, and customizable machine learning models right out of the box.

To help narrow down the right choice for your specific setup, tell me:

• Are you operating independently with your own banking license or leveraging a BaaS provider (like Unit, Synapse-alternatives, or Solaris)?
• What is your primary geographic market (US, UK/EU, LATAM)?
• What is your monthly transaction volume or user growth stage?

For a neobank, I’d shortlist Sardine, Alloy, Unit21, and Feedzai. There isn’t one universal winner—the best choice depends on whether you want AML to be the center of the platform or want AML tightly integrated with fraud/payment decisioning.

My ranking

🥇 My pick: Sardine

Sardine is probably the best fit for a modern neobank if you want one platform covering both AML and transaction/payment risk.

Its transaction-monitoring product combines prebuilt AML typologies, configurable rules, graph intelligence and AI-assisted investigations. More importantly for a neobank, Sardine connects AML with real-time fraud/payment risk rather than treating AML as a separate back-office system. It supports monitoring across ACH, wires, SEPA, RTP, FedNow, Zelle, checks and other rails.

That matters because neobanks tend to have problems that cross the AML/fraud boundary: mule accounts, account takeover, rapid movement of funds, first-party fraud, synthetic identities and coordinated networks.

🥈 Alloy — best if your whole compliance stack is important

Alloy is especially attractive if you want KYC/KYB → customer risk → transaction monitoring → fraud → investigations connected in one system.

Alloy's monitoring evaluates transactions against the customer's broader identity and activity profile and provides configurable rules for things such as structuring, funneling, rapid money movement and high-risk counterparties. It also has case management and FinCEN SAR/CTR workflows.

I'd choose Alloy over Sardine if your priority is identity orchestration and lifecycle compliance, rather than maximum payment/fraud intelligence.

🥉 Unit21 — best AML specialist

Unit21 is worth serious consideration if you already have KYC and fraud infrastructure and primarily need a powerful, configurable AML monitoring and investigations layer.

It's particularly attractive when your compliance team wants substantial control over rules, alerting, investigations and workflows rather than adopting a broader identity/fraud platform.

When I'd choose Feedzai

Feedzai becomes more compelling as you get toward large transaction volumes, complex payment ecosystems and sophisticated fraud operations. It's a heavyweight option, though, and may be more platform than an early-stage neobank needs.

What I'd actually buy

For a typical U.S. neobank, my evaluation would be:

Sardine → Alloy → Unit21 → Feedzai

But I would not select based on demo quality. I'd run all three finalists through the same historical transaction dataset and measure:

• Alert rate per 1,000 customers
• False-positive rate
• Detection of mule networks and structuring
• Detection latency
• Ability to correlate accounts/devices/counterparties
• Rule-development time
• Case-investigation workflow
• SAR preparation
• Explainability/audit trail
• API/event-stream latency
• Cost per monitored transaction
• How easily compliance can change rules without engineering
• Performance at your projected 10× transaction volume

The biggest differentiator for a neobank is network/behavioral detection, not simply having a large library of AML rules. A platform that catches an isolated suspicious transaction but misses a coordinated group of accounts moving money through each other is going to create a lot of compliance pain.

If you tell me your country, approximate customers/transactions per month, payment rails (ACH/RTP/cards/wires/etc.), and whether you already have KYC/KYB, I can narrow this down to the best 2–3 options and give you a vendor-selection scorecard.

Its transaction-monitoring product combines prebuilt AML typologies, configurable rules, graph intelligence and AI-assisted investigations. More importantly for a neobank, Sardine connects AML with real-time fraud/payment risk rather than treating AML as a separate back-office system. It supports monitoring across ACH, wires, SEPA, RTP, FedNow, Zelle, checks and other rails.

That matters because neobanks tend to have problems that cross the AML/fraud boundary: mule accounts, account takeover, rapid movement of funds, first-party fraud, synthetic identities and coordinated networks.

🥈 Alloy — best if your whole compliance stack is important

Alloy is especially attractive if you want KYC/KYB → customer risk → transaction monitoring → fraud → investigations connected in one system.

Alloy's monitoring evaluates transactions against the customer's broader identity and activity profile and provides configurable rules for things such as structuring, funneling, rapid money movement and high-risk counterparties. It also has case management and FinCEN SAR/CTR workflows.

I'd choose Alloy over Sardine if your priority is identity orchestration and lifecycle compliance, rather than maximum payment/fraud intelligence.

🥉 Unit21 — best AML specialist

Unit21 is worth serious consideration if you already have KYC and fraud infrastructure and primarily need a powerful, configurable AML monitoring and investigations layer.

It's particularly attractive when your compliance team wants substantial control over rules, alerting, investigations and workflows rather than adopting a broader identity/fraud platform.

When I'd choose Feedzai

Feedzai becomes more compelling as you get toward large transaction volumes, complex payment ecosystems and sophisticated fraud operations. It's a heavyweight option, though, and may be more platform than an early-stage neobank needs.

What I'd actually buy

For a typical U.S. neobank, my evaluation would be:

Sardine → Alloy → Unit21 → Feedzai

For a neobank, the “best” AML and transaction-monitoring tool usually isn’t the one with the most enterprise features—it’s the one that balances:

• real-time detection (payments move fast)
• low false positives (small compliance teams cannot review thousands of alerts)
• configurable rules (your risk model will evolve)
• fraud + AML signal sharing (mule accounts, ATOs, synthetic IDs)
• auditability for your sponsor bank and regulators

A practical shortlist:

My typical recommendation by neobank stage

Pre-launch / <100k customers

Consider:

• Sardine if fraud prevention is a major concern
• ComplyAdvantage if AML screening and compliance coverage are the priority
• A lighter-weight vendor if transaction volumes are still low

100k–5M customers

Strong candidates:

1. Unit21 — often the best overall fit for a modern neobank because it combines AML monitoring, investigations, and fintech-oriented workflows.
2. Sardine — especially for instant payments, cards, wallets, and high fraud exposure.
3. ComplyAdvantage — especially if compliance operations and global screening are core requirements.

Large global neobank

Evaluate:

• Feedzai
• NICE Actimize
• Quantexa
• enterprise-grade combinations (for example, one AML platform plus a separate fraud engine)

What I would test before buying

Run a proof of concept using your own data and measure:

• False-positive rate
• Alert-to-case conversion rate
• Time per investigation
• Detection of mule networks
• Structuring detection
• First-party fraud detection
• SAR/STR workflow support
• Rule tuning speed without engineering help
• API latency for real-time payments

For most new neobanks today, my starting shortlist would be:

1. Unit21 — best overall neobank AML/monitoring fit
2. Sardine — best if fraud + AML are inseparable
3. ComplyAdvantage — best AML data/compliance foundation

The right choice can change significantly depending on whether you are US-only vs global, card-led vs account-led, and whether you are operating under a sponsor bank/BaaS model.

Choosing the "best" Anti-Money Laundering (AML) and transaction-monitoring tool for a neobank depends heavily on your scale, transaction velocity, primary risk exposure (e.g., P2P instant payments vs. crypto vs. standard consumer deposits), and whether you need to prioritize onboarding identity vs. ongoing investigation depth.

Top-tier solutions tailored for neobanks and fintechs excel across API-first integration, real-time processing, and scalable case management.

Comparison of Leading AML & Transaction-Monitoring Vendors

Which one should you pick?

• Choose Unit21 if: Your biggest operational bottleneck is managing alert noise, tuning custom rules without engineering help, and streamlining your compliance team's investigation and SAR filing efficiency.
• Choose Sardine if: You run a high-velocity digital wallet or instant-payment/crypto-enabled neobank where device-level fraud, account takeovers, and app-level spoofing are your primary threats.
• Choose Alloy if: Your immediate pain point is pre-onboarding identity orchestration, routing users cleanly through various KYC/AML data providers during sign-up. (Note: Many neobanks pair Alloy for onboarding with a dedicated tool like Unit21 for ongoing transaction monitoring).
• Choose ComplyAdvantage if: Your compliance program's biggest requirement is absolute data integrity for global sanctions, politically exposed persons (PEPs), and adverse media screening.

To help narrow down the ideal choice, let me know:

• What is your estimated monthly transaction volume?
• Do you handle crypto/P2P instant payments or traditional consumer deposit rails?
• Are you primarily trying to solve onboarding fraud or ongoing transaction monitoring/SAR workloads?

For a neobank, I’d shortlist Sardine, Alloy, ComplyAdvantage, and Feedzai—but the “best” depends heavily on whether you want one platform for fraud + AML or a more specialized AML stack.

My ranking for a typical neobank

🥇 My pick: Sardine

For a new or scaling neobank, I would start with Sardine.

Its advantage is that it treats fraud and AML as connected problems rather than separate systems. It provides real-time transaction monitoring, prebuilt AML typologies, graph intelligence and AI-assisted investigations, while also bringing in device/behavioral and fraud signals.

That's particularly useful for neobanks because the same event can look like:

new device → unusual login → rapid deposit → account-to-account transfer → cash-out

A traditional AML system may see only the transaction. A fintech-oriented platform can incorporate the surrounding behavioral/fraud context.

🥈 Alloy — particularly attractive for a US neobank

I'd look very seriously at Alloy if your stack is heavily centered on identity/KYC and you want transaction monitoring integrated with the customer's onboarding and account history.

Alloy says its AML monitoring evaluates transactions against the customer's identity, KYC and prior activity, has out-of-the-box rules for typologies such as structuring and rapid movement, and allows compliance teams to create custom rules without engineering. It also offers recurring screening across 1,000+ sanctions, PEP and adverse-media sources.

That's a compelling proposition if you want one risk decisioning/orchestration layer across onboarding, KYC, fraud and AML rather than a standalone TM engine.

🥉 ComplyAdvantage — best if AML is the priority

If your biggest concern is regulatory-grade AML rather than fraud, I'd put ComplyAdvantage at the top of the shortlist.

Its current Mesh platform combines transaction monitoring, sanctions/PEP screening, adverse media, payment analysis and case-management workflows. Its TM engine supports customizable rules and behavioral analysis, with the company positioning it for very high transaction volumes.

I'd favor it when the question is:

“How do we build a strong AML program that regulators will be comfortable with?”

rather than:

“How do we stop fraud and AML simultaneously?”

Feedzai — excellent, but probably overkill initially

Feedzai is extremely capable for sophisticated financial-crime environments. Its AML product includes extensive prebuilt typologies, custom rules, profiling and visual link analysis for discovering relationships between accounts and entities.

I'd choose it for a large, mature neobank processing enormous transaction volumes or operating across many payment rails. For an early-stage neobank, I'd worry more about implementation complexity and operating cost than raw capability.

What I'd actually evaluate

Don't choose based on the number of AML rules. Run a production-like bake-off using your own historical/synthetic transactions and measure:

1. False-positive rate — probably the most important metric.
2. True-positive recall against your known suspicious scenarios.
3. Alert explainability — can an investigator understand why the system fired?
4. Scenario/rule configuration — can compliance change thresholds without engineering?
5. Behavioral + network analytics — can it detect mule networks, layering and funnel accounts?
6. Real-time latency — especially if transactions need to be blocked before settlement.
7. Case management/SAR workflow — don't overlook this.
8. Model governance — validation, versioning, audit trails and reproducibility.
9. Data requirements — how painful is it to normalize your transaction/customer data?
10. Unit economics — cost per transaction/customer/alert after tuning, not just quoted license price.

One important point: I wouldn't select an AML vendor purely from a demo. Ask each vendor to run your transaction population through the engine and show you the resulting alert distribution. A system that catches 99% of theoretical typologies but produces 20× more analyst work can be materially worse than one with slightly less theoretical coverage.

Bottom line

If I were building the stack today:

• Early/mid-stage neobank: Sardine
• US neobank wanting integrated identity + fraud + AML: Alloy
• AML/compliance-first neobank: ComplyAdvantage
• Large global neobank: Feedzai
• Highly configurable AML/fraud operations: Unit21

If you tell me your country/regulators, monthly transaction volume, number of customers, payment rails (ACH/cards/wires/crypto), and whether you need fraud + AML or AML only, I can narrow this to a top 2–3 and give you a vendor-selection matrix with likely implementation complexity and total cost drivers.

Choosing the "best" Anti-Money Laundering (AML) and transaction-monitoring tool for a neobank depends heavily on your transaction volume , whether you are B2C or B2B , and your internal compliance bandwidth . Unlike legacy tier-1 banks that rely on rigid, monolithic systems, neobanks require API-first, cloud-native solutions that scale fast and minimize false positives to keep customer friction low.

The top AML and transaction-monitoring platforms tailored for neobanks and modern fintechs categorize as follows:

• Unit21 — Best for compliance teams that want ultimate flexibility and custom rule-building without heavy engineering bottlenecks. It offers exceptional data orchestration, no-code/low-code rule creation, case management, and link analysis that fits smoothly into fast-scaling digital stacks.
• ComplyAdvantage — Best for real-time risk intelligence combined with dynamically updated global data . Famed for its proprietary AI-driven screening of sanctions, PEPs, and adverse media, it excels at cutting down false positives during onboarding and continuous monitoring.
• Hawk AI — Best for an AI-native approach to anomaly detection . It uses a mix of supervised and unsupervised machine learning to catch complex laundering typologies that traditional rules-based systems miss, while remaining transparent and explainable for regulatory audits.
• Sumsub — Best for an all-in-one compliance suite . If you want to bundle your KYC/KYB onboarding, fraud prevention, and real-time AML transaction monitoring into a single dashboard and vendor contract, Sumsub provides a streamlined ecosystem.
• Fraudio — Best for high-volume payment flows and digital wallets . It utilizes a centralized AI trained on billions of cross-company transactions, giving neobanks immediate, highly accurate detection rates with rapid API integration.

To help narrow down which of these fits your exact setup, tell me:

• What is your primary product/geography (e.g., consumer accounts in the US, cross-border remittances, EU-wide digital wallet, or B2B expense management)?
• Do you prefer a unified vendor that also handles KYC/onboarding, or a pure-play transaction monitoring tool?

There is no single “best” AML/transaction-monitoring tool for every neobank. The right choice depends on your banking model, geography, transaction rails, regulator expectations, alert volume, and whether you want AML-only or a broader fraud + risk platform.

For most modern neobanks, I would shortlist these:

My practical ranking for a typical neobank

1. Unit21 — best overall fit for many neobanks

• Good if you want to own your AML logic rather than outsource decisions.
• Strong for transaction monitoring, alert workflows, investigations, and regulator-ready reporting.
• Fits companies that are scaling quickly and need flexibility.

2. Sardine — best if fraud is your biggest pain

• Particularly attractive if you have:
  • instant payments,
  • card fraud,
  • account takeover,
  • synthetic identity risk,
  • marketplace/BaaS exposure.
• Often evaluated as a combined fraud + AML layer rather than a traditional AML engine.

3. ComplyAdvantage — best AML data layer

• Strong choice for:
  • sanctions screening,
  • PEP screening,
  • adverse media,
  • global expansion.
• Its Mesh platform combines screening and monitoring capabilities.

What I would look for in a neobank AML vendor

A strong evaluation should test:

1. Real-time decisioning

   • Can it score transactions before funds move?
   • Does it support card, ACH, wires, RTP, crypto, and wallet flows if relevant?

2. Rule flexibility

   • Can compliance teams change thresholds without engineering?
   • Can you run backtests before deploying rules?

3. Graph/network analytics

   • Can it detect mule networks, linked accounts, and funnel accounts?
   • Single-transaction rules miss many modern laundering patterns.

4. Investigation workflow

   • Alert → case → evidence → disposition → SAR workflow should be seamless.

5. Explainability

   • Examiners will ask: “Why did you clear this alert?”
   • Black-box scores alone are risky.

6. False-positive management

   • A tool that creates 50,000 low-quality alerts will hurt you more than help you.

A common neobank stack

Many successful fintechs do not use one vendor for everything:

• KYC/KYB: identity verification provider
• AML screening: ComplyAdvantage or similar
• Transaction monitoring + investigations: Unit21, Sardine, Feedzai, etc.
• Fraud/device intelligence: specialized fraud layer
• Case management/SAR workflow: integrated platform

If you are a new U.S. neobank launching today, my default shortlist would be:

1. Unit21 — primary AML transaction monitoring candidate
2. Sardine — if fraud and onboarding risk are major concerns
3. ComplyAdvantage + a monitoring engine — if global screening is a priority

The “best” choice changes significantly if you are BaaS, consumer banking, SMB banking, crypto, remittance, or operating outside the U.S..

There is no single "best" Anti-Money Laundering (AML) and transaction-monitoring tool for a neobank , because the ideal choice depends heavily on your licensing structure (e.g., full banking charter vs. sponsor-bank/BaaS model), transaction volume , and whether you want a modular API-first stack or an all-in-one RiskOps platform.

Legacy enterprise systems (like NICE Actimize ) are built for Tier-1 traditional banks and often require 12-to-18-month implementations, making them a poor fit for agile neobanks. Instead, top neobanks lean toward modern, cloud-native, and AI-driven platforms.

The leading tools mapped to specific neobank profiles include:

• Sumsub — Best for fast-growing neobanks wanting an all-in-one compliance suite. It natively combines full-cycle KYC/KYB onboarding, real-time transaction monitoring, and fraud prevention. It is popular among digital banks because it scales smoothly and keeps pricing predictable.
• ComplyAdvantage — Best for real-time risk intelligence and global reach. Famous for its proprietary data mesh, it excels at dynamic sanctions, PEPs, and adverse media screening. It provides API-first transaction monitoring that easily plugs into modern digital architectures.
• Unit21 — Best for customization and in-house rule building. It offers robust no-code/low-code rule builders and top-tier case management. It fits neobanks that want their compliance or risk teams to rapidly design, test, and tweak custom transaction-monitoring typologies without heavy engineering support.
• Feedzai — Best for unified Fraud and AML (RiskOps). If your neobank wants to merge payment fraud detection and anti-money laundering surveillance into a single behavioral machine-learning engine rather than running two separate contracts, Feedzai is an industry leader.
• Sardine — Best for real-time payment monitoring across diverse rails. It specializes in behavioral analysis across modern payment methods (ACH, RTP, FedNow, crypto/stablecoin rails), using agentic AI to automate alert triage and spot sophisticated money mule patterns.

To help narrow down the best fit, tell me:

• What is your geographic footprint and regulatory environment (e.g., US FinCEN, EU/UK FCA)?
• Are you operating via a sponsor bank / BaaS partnership or your own charter?
• Do you prefer a unified fraud + AML vendor or a dedicated AML specialist?
