What is Fraud and Abuse Protection? 

Fraud and abuse protection is the practice of connecting the behaviors, relationships, and intent behind every account into a decision you can defend, so you stop real threats without turning away good customers.

Tools alone rarely get there. They read signals one at a time, so the blind spots in behavior, policy, and context never surface.

FiveBy delivers it as a program: experienced practitioners, purpose-built technology, and an operating model that adapts as fraud does. We work on the stack you already run, and operate it with you or on your behalf.

We Fight Smarter

Model Tuning & Validation

We calibrate the models you already run to your specific risk profile, improving accuracy and cutting the false positives that turn good customers away.

Behavioral Fraud Analysis

We connect the behaviors, relationships, and intent behind every account into one picture, so you see the operation working across your platform, not a string of unrelated incidents.

Payments Abuse Mitigation

We find and shut down refund fraud, chargeback abuse, and the other tactics that exploit payment systems, then build the controls that keep them out.

Platform Abuse Defense

We defend against account takeover, insider threat, and coordinated external abuse by connecting the relationships behind the accounts, not treating each incident on its own.

Fraud costs more than money. It costs trust, retention, and growth

Every risk decision is a business decision. We surface the cost of the risk and the return on mitigating it, so you protect the revenue and the customer trust your growth depends on.

Flexible Engagement to Match Your Needs

Whether you need comprehensive fraud protection or targeted support for specific vulnerabilities, FiveBy offers flexible engagement models that adapt to your business requirements.

FAQ

Fraud and Abuse Protection: Common Questions

What is fraud and abuse protection?

Fraud and abuse protection is the practice of connecting the behaviors, relationships, and intent behind every account and transaction into a decision you can defend, instead of reacting to isolated alerts. FiveBy delivers it as a program: experienced practitioners, purpose-built technology, and an operating model that keeps working as fraud changes.

How is fraud and abuse protection different from buying a fraud tool?

A tool scores events one at a time and hands you a signal. Fraud and abuse protection turns those signals into decisioning: what the pattern means, what to do about it, and why the call holds up later. FiveBy builds that layer on top of the tools you already run.

Do we have to replace the fraud tools we already use?

No. FiveBy is tool-agnostic and works on top of your existing stack, including Sift, Forter, Stripe Radar, Spec, and Kount. Most engagements start by making the investment you have already made perform, not by adding another platform to it.

Does FiveBy operate the program, or only advise?

Both are real engagements. We operate the program with you, or on your behalf, so you get an enterprise-grade capability without standing up a costly internal team. When you would rather hold it in house, we build the capability with your team and hand it over.

What types of fraud and abuse does FiveBy cover?

Fake account creation, account takeover, promotion and refund abuse, chargeback abuse, payment fraud, insider threat, and coordinated platform abuse. Because we connect the relationships behind the accounts, the same work usually surfaces the organized activity running underneath several of those categories at once.

How does FiveBy make fraud decisions defensible?

Every decision carries its reasoning: the signals behind it, the pattern they form, and the judgment or rule applied. That record is what lets you explain a call to a customer, an auditor, or a board months later, and it is why consistency holds as your volume grows.
