Our Approach

Behind every fraud attempt is an identity

Fraud takes many forms, but it always starts with an identity, whether real, stolen, or fabricated. Alloy draws on 270+ data solutions to build a complete picture of who is behind every application, account, and transaction, putting the person at the center of every decision.

First-party Fraud

Catch first-party fraud before it escalates

Credit fraud

Credit fraud

Without Alloy

Credit, onboarding, and fraud data is siloed, so the system can’t spot a carefully planned bust-out scheme or a subtle misrepresentation of a customer’s financial situation.

With Alloy

Combine onboarding, credit, and fraud in the same system to make more informed risk decisions, so slow-burn schemes don't go undetected.

Transaction fraud

Transaction fraud

Without Alloy

A customer initiates a transfer to immediately remove funds from the account. The institution absorbs the loss, and the pattern compounds quickly across a portfolio.

With Alloy

Transaction and behavioral history makes it easier to distinguish legitimate money movement from abuse before funds leave your institution.

Risk and Revenue

Better fraud decisions mean better business outcomes

Create the conditions for your financial institution or fintech to scale confidently. Roll out more products, approve more qualified applicants, and grow your relationship with existing customers.

Second-party Fraud

Stop good customers from becoming unwitting accomplices

Money Muling

Money muling

Without Alloy

An account that looks normal moves illegally obtained funds, and the account holder may not even know they're part of a scheme.

With Alloy

Spot likely mule accounts at onboarding, then monitor for risky account changes, unusual money movement, device/login anomalies, and suspicious behavior.

Scams

Scams

Without Alloy

The target is your customer, not your systems, but fraud losses can still land on your organization and diminish customer trust.

With Alloy

Catch behavioral and contextual anomalies early, even when the customer appears to be acting voluntarily. Continuous identity risk evaluation triggers real-time interdiction, like adaptive friction and step-up verification, in vulnerable moments.

AI Threats

Built for the new era of risk

Generative AI has lowered the cost of committing fraud. Alloy was built to keep up with it. Our Fraud Attack Radar and Fraud Signal machine learning models help you predict sophisticated attacks more precisely, and contain threats as they appear.

Third-party Fraud

Keep bad actors and fake identities out of your system

  • New account fraud

    Without Alloy

    A fraudster applies using a real individual’s personal information. They behave like a normal customer for a while, then cash out.

    With Alloy

    Access over 270+ global data solutions at the point of application to stop bad actors early. Alloy’s Fraud Signal model continuously monitors and scores customers from first touch through ongoing interactions, so you can flag early signs of fraudulent behavior well before funds have left your organization.

  • Synthetic identity fraud

    Without Alloy

    Fabricated or blended identities pass standard verification because fragments of the identity are legitimate.

    With Alloy

    Run data sources in tandem, including third-party models that specialize in identifying fabricated or manipulated identities, to surface emerging synthetic patterns that a linear approach would miss. 

  • Identity fraud

    Without Alloy

    Stolen credentials clear basic verification because they belong to a real person.

    With Alloy

    Use layered solutions such as document verification, device intelligence, and bank account validation to maintain a dynamic customer profile. Suspicious changes in contact details, behavior, or account access trigger additional verification.

  • Account takeover

    Without Alloy

    A legitimate customer's account gets hijacked, and the fraudulent activity that follows can look like ordinary behavior until it's too late.

    With Alloy

    Fraud Signal connects seemingly disconnected events by taking an identity-centric approach, flagging suspicious activity in real time, so you can stop account takeovers before they succeed.

  • Business fraud

    Without Alloy

    Fraudulent actors operating behind a fake business use a bank account to access financial products or obscure the origin of funds.

    With Alloy

    Run KYB in parallel with KYC, AML, and fraud checks on UBOs and stakeholders to stop business fraud at origination. Continually monitor business identity, ownership, registry changes, and user activity to flag when high-risk behavior emerges.

Fraud Ring Attacks

Identify coordinated attacks in your origination funnel

Fraud rings probe quietly before they strike at scale. Fraud Attack Radar detects attack patterns as they form, and alerts your team immediately. That way, you can quickly contain the threat without closing your funnel.

FAQs

  • What is Alloy, and how does it support fraud prevention across the customer lifecycle?

    Alloy unifies identity verification, risk-based authentication, and fraud detection software, so fintechs and financial institutions can grow with confidence. Our identity and fraud prevention platform integrates over 270 third-party data solutions into a single decisioning engine, providing automated, configurable controls that prevent fraud and enable organizations to deliver a great experience across the customer lifecycle.

  • What kinds of financial institutions does Alloy help with fraud prevention?

    Alloy supports financial organizations of all sizes, from global banks modernizing enterprise-wide fraud strategies to local credit unions and fast-scaling fintechs. 25% of the top 50 US banks, 7 out of the top 10 credit unions, and many of the world’s largest fintechs choose Alloy for fraud prevention today. Our platform’s flexibility makes it valuable whether you’re streamlining a complex enterprise tech stack or equipping a lean fraud team with strong, out-of-the-box controls.

  • How does Alloy reduce fraud losses?

    Alloy reduces fraud losses in banking by flagging high-risk applications and account activity in real time and giving teams the tools to act before it results in financial damage. A configurable policy-builder and AI-driven models adapt to shifting fraud patterns, enabling financial organizations to stop more bad actors while minimizing false declines. The result is fewer losses, lower fraud costs and operational expenses, and more legitimate customers approved. Fraud prevention turns from a cost center into a driver of growth.

  • How do I integrate Alloy’s fraud tools into my platform?

    Alloy provides pre-built integrations to third-party data solutions, low-code native SDK and webhooks to plug into existing workflows with minimal engineering. Our platform is accessed primarily through a fully RESTful API, supporting seamless integration with platforms and systems, including Account Opening Systems, Loan Origination Systems, CRMs, and ESB Layers. The Alloy Testing Suite lets you build and validate end-to-end policies before promoting to production, while feature flags and versioned policies make it safe to roll out gradually across channels.

  • How does Alloy fit in with my CIAM?

    For many financial organizations, adopting Alloy means integrating alongside existing Customer Identity and Access Management (CIAM) systems. Their CIAM handles credentials, SSO, sessions, and entitlements; Alloy adds the identity-risk layer that verifies at account opening and at high-risk touchpoints. Our risk-based authentication is enriched with third-party signals, and triggers dynamic step-up or force session expiration when risk is elevated. Together, CIAM systems and Alloy provide a layered approach to risk-based authentication and verification, enabling safe growth by protecting your bottom line without hampering the client experience.
