Financial institutions have never been more connected, yet more vulnerable. As systems evolve to handle faster payments and broader access, fraud is evolving alongside them.
In 2024, the Federal Trade Commission reported that consumer losses to fraud reached a staggering $12.5 billion, marking a substantial increase from previous years.
What's needed are fraud prevention solutions built to act fast, adapt quickly, and prevent fraud before it happens, all without disrupting the customer experience.
This article explores how fraud is evolving, highlights the most effective prevention solutions in 2025, and outlines how financial institutions can stay ahead of emerging threats.
Fraud prevention solutions are systems and strategies that help financial institutions detect, stop, and reduce fraud before it causes damage.
These solutions work in real time, analyzing transactions, customer behavior, and patterns to flag suspicious activity as it happens.
Key features of effective fraud prevention solutions include:
Fraud in 2025 is more complex than stolen cards or fake checks. Here's what today's banks are up against:
First-party fraud happens when people use their real identities to lie, such as faking income to get credit they plan to default on. It's hard to catch because the fraudster is also the account holder.
In 2024, first-party fraud cost U.S. financial institutions and vendors over $100 billion annually.
During the 2024 holiday season, 13% of Americans and 40% of Gen Z admitted to committing first-party fraud, including disputing legitimate charges or falsely claiming lost items.
Synthetic identity fraud happens when fraudsters mix real and fake details to create false identities, open accounts, build credit, and disappear after maxing out credit lines.
This type of fraud has emerged as the fastest-growing form of financial crime, surpassing traditional credit card fraud and identity theft. In the U.S., the number of accounts opened with synthetic identities grew 18% in 2024 compared to the previous year.
Account takeover fraud involves unauthorized access to legitimate customer accounts, often through phishing, credential stuffing, or social engineering.
Once inside, fraudsters can drain funds, make fraudulent transactions, or change account details to cover their tracks.
In 2024, 68% of organizations say cloud account takeovers present a significant security risk.
Despite the rise of electronic payments, check fraud remains an extensive issue.
Fraudsters exploit gaps in deposit processing through methods like forged or altered checks and counterfeit payees. The shift to remote deposit capture has introduced new vulnerabilities, as banks process checks without physical inspection.
Checks are the payment method most often subjected to fraud, with 63% of organizations reporting check fraud activity in 2024.
Fraudsters target mobile apps, online portals, and APIs as financial services go digital. Weak security around logins, sessions, and transactions allows them to do so.
Mobile applications have shown vulnerabilities. A study revealed that 75% of mobile apps contain at least one security flaw, making them susceptible to breaches.
Digital wallets and contactless payments are not exempt from these threats. In 2024, consumers reported losing $347 million to scams involving digital wallet payment apps.
Here's a look at 10 fraud prevention solutions helping banks stay ahead of threats in 2025:
In 2025, nearly 70% of bank fraud losses originate from undetected activity during transactions or deposits.
Real-time risk scoring addresses this by assigning a fraud probability score to every action, whether a teller-assisted check deposit or an ATM submission.
How it works:
AI models analyze key details like amount, account age, and behavior to generate a risk score. High scores trigger holds, alerts, or escalations.
Actionable strategies:
VALID Systems' Real-Time Loss Alerts (RTLA)© delivers pre-clearance fraud scoring and alerting across teller lines and ATMs, identifying over 75% of loss-bound check items before they post.
While most behavioral fraud detection focuses on digital channels, in 2025, banks are also turning to behavior-based profiles for check writers and receivers.
How it works:
Each account develops a behavioral baseline, such as typical check issuances, recipient frequency, and geographic zones.
Actionable strategies:
VALID's INclearing Loss Alerts catch altered or out-of-pattern checks during clearing, not just at the point of deposit, protecting against changes made after image capture.
Traditional Positive Pay is rule-based: match the issue file to the presented check, and alert if it is mismatched. But machine learning now adds context, distinguishing between typos and actual tampering.
How it works:
ML models review previous exceptions, outcomes, and user behavior. They learn which types of mismatches are most likely fraud (e.g., check stock mismatch + payee change) and prioritize them.
Actionable strategies:
VALID's InteliFUNDS© improves Positive Pay by using fraud pattern recognition to differentiate human error from real risk, while guaranteeing covered losses on high-risk exceptions it clears.
According to the U.S. Postal Inspection Service, altered check fraud spiked 385% from 2021 to 2024. Fraudsters chemically wash or digitally edit legitimate checks. Modern forensic image scanning can spot even subtle tampering.
How it works:
AI models examine pixelation, spacing, font mismatches, ink density, and even pen stroke dynamics to detect edits invisible to the human eye.
Actionable strategies:
Fraud rarely hits just one institution. In 2025, consortium fraud intelligence has become a standard weapon, sharing anonymized data on suspect accounts, check series, or origin banks.
How it works:
Your fraud system ingests alerts and high-risk patterns from other banks and fintechs in the network. Real-time matching previously flagged suspects the moment they appear.
Actionable strategies:
VALID Edge™ gives your bank access to a shared intelligence platform containing over 300 million account records. It detects duplicate, rerouted, or kited checks linked to previous fraud events.
Legacy systems rely on fixed hold times. Leading banks use dynamic fraud scoring to decide how long to hold funds or when to make them available.
How it works:
Each deposited check gets a fraud risk score. The system assigns instant availability, partial or complete hold based on thresholds, without manual override.
Actionable strategies:
InteliFUNDS© analyzes each check and determines how quickly to release the funds, reducing unnecessary holds and protecting your institution from risky deposits.
First-party fraud, like intentional overdrafts, deposit kiting, or check fraud by legitimate customers, is among the fastest-growing fraud categories.
How it works:
AI monitors deposit timing, refund behavior, and overdraft cycles, and it checks usage to spot signs of deception before traditional systems flag them as fraud.
Actionable strategies:
As fraud migrates to mobile, banks face threats in transactions and how sessions begin and end. In 2025, session hijacking and mobile banking credential theft will be among the top digital risks.
How it works:
The system continuously scores session behavior, such as timing, location, IP address, and device model. When it detects increased risk during a session, it downgrades access or prompts the user to re-authenticate.
Actionable strategies:
Use dual-channel verification to confirm high-risk check activity by contacting the account holder through a second method, such as a secure message or app prompt.
How it works:
The system flags a check as high-risk and prompts the customer for additional input, such as confirming the payee or amount. No action = no clearing.
Actionable strategies:
Frontline workers are your last line of defense, but only if they have the proper guidance. Fraud detection prompts built into teller software or ATM systems help staff step in where automation can't.
How it works:
As a check is deposited, live fraud scores prompt messages like "Check flagged: verify ID" or "Check risk level high: Refer to supervisor."
Actionable strategies:
VALID's RTLA© integrates directly with teller and ATM platforms to deliver actionable alerts before a check is accepted, minimizing fraud at the edge of your network.
