Risk and fraud

Fraud is a universal challenge that is constantly evolving, meaning merchants and issuers must always stay one step ahead. The complexity of threats continues to escalate, too. And when every transaction carries a risk, each split-second decision carries the question: is this transaction legitimate or fraudulent?

The volume of global digital commerce requires data-driven oversight, not manual guesswork. The cost of getting it wrong can be huge. In the U.S. alone, cyber-enabled fraud losses amount to about $13.7 billion a year.1 Meanwhile, declining valid transactions — known as false declines — to avoid fraud is costly. Optimizing their authorization rates is now rated as “extremely important” by more than 40% of merchants globally.2 They must find ways to combat sophisticated attacks without adding more friction that will ultimately drive customers away.

Instead of waiting for a crime to happen and fixing it later, advanced analytics let you identify elevated risk earlier in the transaction lifecycle. Tools like machine learning and generative AI act like digital detectives, scanning billions of transactions to learn exactly what good and bad spending looks like. This massive visibility helps inform your decisions and interventions, like blocking scammers instantly in real time, while rolling out the red carpet for legitimate customers — closing the gap between risk and revenue.

When it comes to fraud risk scoring and analytics, VisaNet processes more than 269 billion transactions annually,3 offering a massive dataset for benchmarking and detection. Visa has an added advantage in being positioned on both sides of the transaction, allowing us to connect merchants and financial institutions to share data securely. This means that financial institutions have access to more higher-quality data to feed into their models, allowing them to more accurately calculate important analytics like fraud risk scores.

By understanding how fraud scoring works and how it can help reduce fraud, you can help stop bad transactions, approve more good ones and ensure a frictionless experience.

Fraud scoring is a way to rate transactions based on their level of risk. Calculated in real time, it ensures that each payment is evaluated to detect the likelihood of a customer being genuine, risky or fraudulent. A numerical risk value, or score, is used — from 0 (very safe) to 99 (high risk).

So how does fraud scoring reduce payment risk? Utilizing automated AI models, fraud scoring happens seamlessly behind the scenes within milliseconds, and the decision is used to identify genuine transactions while declining fraudulent ones. This not only helps to reduce fraud but also streamlines the customer experience by keeping every payment as frictionless as possible.

There are two common approaches used together in fraud risk management: rules-based controls and risk-based, model-driven scoring. Machine learning models analyze transactions and generate risk signals that reflect changing customer and ecosystem behavior. Rules then apply thresholds or policies to those risk signals to inform what action to take, such as allowing a transaction to proceed or triggering additional checks.

Generative AI takes fraud scoring and analytics a step further and helps merchants and issuers stay at the cutting edge in terms of countering emerging threats posed by fraudsters. Generative AI can support investigators by summarizing risk signals and historical context, helping increase efficiency in review and documentation.

Fraud scores help inform decisions, which are configured by issuers, acquirers or merchants — and ultimately lead to individual interventions. This is why having more reliable, better-quality data is so important.

Different types of data are used to calculate a score, and they can carry a different weighting, too. For example, an unexpected customer location is likely to matter less than multiple failed transaction attempts. And because businesses all look at the data differently, depending on factors like their risk appetite and what models they use, the same transaction can receive multiple scores. Additionally, having access to rich, accurate data that allows for continuous learning is increasingly valuable, so your business is able to adapt to the latest methods used by fraudsters.

Featurespace, a Visa solution, uses Adaptive Behavioral Analytics and Automated Deep Behavioral Networks to provide the insights you need, including early detection of scam patterns, so you can take the decisions that are right for your business.

Here’s an overview of how Visa and Featurespace’s fraud scoring solutions calculate fraud scores and help your business balance risk:

  1. For merchants, transaction control through intelligence: fraud scoring takes place before the authorization stage. This process is like an automated gatekeeper, analyzing data points including device intelligence, geolocation and transaction history to filter out bad orders before they reach the bank. Merchants can take control with Visa solutions such as Decision Manager (DM) and Visa Protect Risk Insights (VPRI).
  2. For issuers, making the decision: the scoring element is used to approve or decline a transaction and this takes place during authorization. In mere milliseconds, tools such as Visa Advanced Authorization (VAA) analyze the probability of fraud to help the bank approve the transfer of funds between the two parties. Analytics can provide dynamic visibility to behavior and anomalies. Financial institutions use dashboards to compare their fraud rates against industry peers and regional benchmarks. Identify specific spikes in fraud types, such as card-not-present versus card-present or high-risk merchant category codes (MCCs).
  3. The data engine: risk scores are generated by comparing the customer’s current transaction with billions of historical network transactions to establish validity.

Pioneered by Featurespace, a Visa solution, Adaptive Behavioral Analytics (ABA) are industry-leading models where a customer’s transactions are analyzed to recognize patterns of “good” or “normal” behavior and therefore identify suspicious or abnormal behavior. By understanding what “good” transactions look like rather than simply flagging “bad” activity, ABA helps financial institutions catch scams as they surface, improving fraud detection while reducing false alarms that frustrate customers.

Visa Provisioning Intelligence (VPI) for banks and issuers is a smart, proactive tool designed to support real-time risk assessment. It assesses requests when someone tries to add a payment credential to a digital wallet or device, a process known as “provisioning.” By assessing the probability of fraud during the token provisioning phase, VPI provides real‑time risk scoring that helps banks and issuers identify potentially fraudulent provisioning activity. This enables issuers to block high‑risk token requests before a digital token is created, adding an important layer of security at the point of entry.

Visa Consumer Authentication Service (VCAS) for issuers is a data‑driven, hosted solution designed to make online shopping safer and smoother. It supports issuers by managing their authentication strategies within 3-D Secure programs. By leveraging enriched data and a dedicated VCAS risk score, the service enables issuers to apply real‑time, rule‑based decisioning to determine whether transactions can proceed frictionlessly or require additional authentication. This helps enable seamless, risk‑based authentication and delivers a simple and secure digital payment experience.

Visa Deep Authorization (VDA) for financial institutions is one of the risk-scoring tools specifically tailored for the card-not-present landscape. Using AI and deep-learning models, VDA analyzes historical cardholder and merchant transaction behavior to model evolving spending patterns. This technology generates a transaction risk score during the authorization process, helping issuers enhance fraud detection and decisioning. Currently, this powerful solution is available for the U.S. market.

Using its proprietary Adaptive Behavioral Analytics (ABA), Automated Deep Behavioral Networks powered by machine learning, and Large Transaction Model (LTM), the Featurespace Platform helps identify risk, catch new fraud attacks and identify suspicious activity — to include fake account openings and complex merchant fraud — in real time, all while ensuring legitimate transactions continue to flow smoothly.

Visa A2A Protect for financial institutions applies adaptive, real‑time risk scoring to help assess fraud and scam risk in account‑to‑account payments. Designed to deliver value from day one within a single institution, it uses each bank’s own transaction data and customer behavior to establish a baseline of normal activity and identify anomalous real-time payments (RTP) activity as payments are initiated. This supports faster, more informed responses to emerging risks without relying solely on manual review and while keeping control firmly with the institution.

When institutions choose to opt in, Visa A2A Protect can also incorporate intelligence across banks, to enrich those risk signals with broader contextual insight. This additional layer helps financial institutions understand how emerging scam patterns may be evolving beyond their own environment, supporting more resilient and informed fraud strategies over time.

Visa Protect Authentication Intelligence (VPAI) for banks and issuers provides a risk-based authentication score to help assess fraud risk in online payments. A key tool within the Visa authentication suite, it’s designed to enable seamless, data-led decisioning during authentication. By using this intelligence, banks and issuers can better determine whether an authentication request can proceed frictionlessly or if it requires additional verification — helping deliver a simple and secure digital payments experience.

Visa Analytics Platform (VAP) for issuers is a data-driven analytics platform that provides industry benchmarks and insights to support fraud monitoring and optimization.

Visa Advanced Authorization (VAA) for issuers is one of the tools that generates a transaction risk score by analyzing network‑level data to identify emerging fraud patterns.

Visa Risk Manager (VRM) for issuers is one of the tools that applies configurable, rule‑based controls to transaction risk scores to support authorization decisioning. For example, VRM can be used alongside Visa Advanced Authorization (VAA), which generates a transaction risk score during authorization.

Decision Manager for merchants automates fraud detection using advanced machine learning and data-driven insights from billions of transactions.

Staying on the lookout for fraud is a constant battle but with Visa fraud scoring and analytics solutions you can use data as your secret weapon — saying no to scammers, while saying yes to more genuine customers.
