As e-commerce and digital payments continue to surge, so does the sophistication and frequency of fraudulent activities targeting online merchants. In 2025, businesses—especially those in high-risk sectors like CBD, gambling, and adult entertainment—face immense pressure to safeguard their payment ecosystems.

Effective fraud detection isn’t just about preventing financial losses; it’s about maintaining customer trust, complying with regulations, and ensuring seamless payment experiences. Secure payments boost customer trust by reassuring users that their transactions are protected and handled responsibly.

Cathedral Payments stands at the forefront of fraud prevention, utilizing cutting-edge technologies and expert strategies to shield businesses from fraud while maximizing legitimate sales.

In this article, we will explore the nuances of fraud detection in online transactions, the types of fraud common today, and how Cathedral Payments empowers merchants with robust fraud protection.

What is Fraud Detection in Online Payments?

Fraud detection in online payments refers to the set of techniques and tools used to identify potentially fraudulent transactions before they are completed. The goal is to intercept unauthorized or deceptive transactions that could result in financial loss, reputational harm, or regulatory penalties.

The complexity of fraud detection arises from the need to distinguish between legitimate customers and fraudsters accurately. False positives—when genuine transactions are mistakenly flagged as fraud—can frustrate customers and lead to lost sales, while false negatives allow fraud to slip through, causing costly chargebacks and data breaches.

Fraud detection systems analyze transaction data using a combination of:

  • Rule-based filters that flag transactions based on predefined criteria (e.g., high transaction amounts, mismatched billing and shipping addresses).

  • Behavioral analytics that track customer behavior patterns and detect anomalies.

  • Machine learning and AI algorithms that evolve by learning from vast amounts of historical data to detect new fraud patterns.

  • Device and network fingerprinting to identify suspicious device or IP address usage.

  • Multi-factor authentication mechanisms to add layers of verification.

Effective fraud detection protects merchants’ revenue and enhances the customer experience by minimizing unnecessary transaction declines.

Common Types of Online Payment Fraud

To build effective defenses, businesses must understand the variety of fraud tactics employed by cybercriminals:

1. Card-Not-Present (CNP) Fraud

The most prevalent type of online payment fraud, CNP fraud occurs when stolen credit card information is used to make online purchases without the physical card. Criminals often obtain card data through data breaches, phishing scams, or purchasing from the dark web.

CNP fraud is particularly challenging because the merchant cannot verify the physical presence of the card or the identity of the cardholder during the transaction. This makes advanced fraud detection technologies essential for mitigating risk.

Industry Insight: According to Javelin Strategy & Research, CNP fraud accounted for nearly 80% of total card fraud losses in 2023, underscoring the critical need for sophisticated detection systems.

2. Identity Theft and Synthetic Identity Fraud

Fraudsters create accounts or make purchases using stolen personal information or fabricated identities composed of real and fake data elements. Synthetic identity fraud is especially insidious because it can go undetected for long periods, gradually building trust before exploiting the account.

3. Friendly Fraud (Chargeback Fraud)

Friendly fraud happens when a legitimate cardholder makes a purchase but then disputes the charge with their bank, often claiming non-receipt or dissatisfaction to get a refund while keeping the goods or services. This type of fraud is a significant source of chargebacks for high-risk merchants.

4. Account Takeover

In this scenario, fraudsters gain unauthorized access to a customer’s account by stealing login credentials, often through phishing or credential stuffing attacks. They then use the account to make unauthorized purchases or withdraw funds.

5. Triangulation Fraud

A complex scam where fraudsters set up a fake online storefront, collect payments from customers, and then use stolen credit cards to order products from legitimate retailers, which are shipped to the customers. This leaves both the legitimate retailer and customers at risk.

How Cathedral Payments Detects and Prevents Fraud

Cathedral Payments uses a multi-layered fraud detection approach that integrates advanced technologies with expert oversight:

1. Artificial Intelligence and Machine Learning

By leveraging AI and machine learning, Cathedral Payments analyzes millions of transactions in real time. The system learns to recognize patterns that indicate fraudulent behavior, such as unusual spending spikes, mismatched geographic locations, or inconsistent device fingerprints.

AI models continuously improve by adapting to new fraud tactics, ensuring merchants are protected against evolving threats.

2. Rule-Based Fraud Filters

Cathedral Payments employs customizable rule-based filters that allow merchants to set parameters based on their business model. Examples include blocking transactions from high-risk countries, limiting transactions above a certain amount, or flagging orders with mismatched billing and shipping addresses.

This flexibility lets merchants tailor fraud prevention to their unique needs.

3. Behavioral Analytics

Understanding customer behavior is key to spotting fraud. Behavioral analytics track metrics such as browsing patterns, time spent on pages, and typical purchase frequency to differentiate between legitimate customers and bots or fraudsters.

Unusual behaviors trigger alerts for further review.

4. Device Fingerprinting and IP Analysis

Cathedral Payments uses device fingerprinting to identify the hardware and software characteristics of the device initiating a transaction. Coupled with IP address analysis, this helps detect suspicious activity like multiple accounts created from the same device or IP addresses from high-risk regions.

5. 3D Secure Authentication

3D Secure (3DS) protocols add an extra layer of authentication, requiring cardholders to verify their identity via passwords or one-time codes during checkout. Cathedral Payments supports 3DS to reduce unauthorized card use and shift liability away from merchants.

Balancing Security and User Experience

While fraud prevention is critical, excessive friction in the checkout process can lead to cart abandonment and lost sales. Cathedral Payments focuses on risk-based authentication, which assesses the risk level of each transaction dynamically:

  • Low-risk transactions are processed quickly without extra steps.

  • High-risk transactions trigger additional verification steps.

This approach minimizes disruption for legitimate customers while keeping fraudsters at bay.

Benefits of Advanced Fraud Detection for Merchants

By partnering with Cathedral Payments, businesses gain:

  • Reduced chargebacks and financial losses, improving profitability.

  • Enhanced customer trust and loyalty through secure, smooth payment experiences.

  • Compliance support with PCI DSS and other regulatory standards.

  • Real-time visibility and control over transactions, enabling rapid responses to threats.

Case Study: Protecting a CBD E-Commerce Store

A leading CBD retailer experienced a surge in fraudulent transactions and chargebacks, threatening their merchant account stability. By integrating Cathedral Payments’ AI-driven fraud detection and customizable filters, the retailer saw a 60% reduction in fraud-related chargebacks within six months, stabilizing their payment processing and improving customer satisfaction.

Emerging Trends in Fraud Detection for 2025

  • Biometric Authentication: Increasing use of fingerprint and facial recognition to verify identities.

  • Blockchain and Decentralized Identity: Enhancing transaction transparency and security.

  • Cross-Industry Data Sharing: Collaboration among merchants and processors to identify emerging fraud patterns.
