7 Advanced Fraud Prevention Solutions to Implement Now

TL;DR

Fighting ecommerce fraud is a continuous effort, and no single tactic guarantees full protection. This post outlines seven advanced solutions merchants can layer together: SMS-based verification, device fingerprinting, dynamic knowledge-based authentication, out-of-band identity proofing, IP geolocation, machine learning, and fraud managed services. The strongest approach combines these technologies with experienced human review rather than relying on any one tool alone.

Fighting fraud is a 24/7/365 effort. And for every minute an e-commerce merchant spends scanning their transactions for fraud and implementing new filters to catch suspicious orders, cybercriminals spend that same minute finding a way around those fraud prevention solutions.

Although no strategy can guarantee 100% protection against savvy fraudsters, several emerging strategies can improve a business’s chances of catching fraud before it does irreparable damage.

Here are six advanced fraud prevention solutions e-commerce merchants should consider adding to their fraud management arsenal today.

1. SMS-Based Verification

Connecting a verified phone number to a customer’s account when the customer first registers on an e-commerce merchant’s website can improve a merchant’s confidence in an e-commerce transaction.

These solutions send a time-sensitive, one-time password via SMS to customers and can help merchants confidently authenticate a client’s identity — even if customers are accessing their accounts from a new computer or browser or are placing a high-dollar order.

Merchants can also use this text-to-verify solution as a way to immediately text details of a purchase to the number associated with a customer’s credit card, allowing them to confirm or deny the purchase without having to make phone calls or log on to accounts.

However, one caveat: SMS authentication will only work if the customer has their mobile phone with them when placing the order. Therefore, although SMS can be a helpful tool, merchants can’t be 100% dependent on it and must use this tool in conjunction with a more comprehensive fraud prevention strategy.

2. Device Fingerprinting

Device fingerprinting offers merchants a more reliable alternative to cookies or IP addresses to uniquely identify a remote computing device or user.

Fingerprinting uses a variety of data points — like IP addresses, time stamps, operating systems and browsers — alongside services like Google reverse geocoding, to let merchants narrow the location of a transaction to a physical address. It’s an effective way for merchants to confirm that a customer is who — and where — they say they are.

Merchants can also assign a unique fingerprint to a combination of data points, store it to their fingerprint database, and use it on future purchases to confirm their legitimacy. Because normal device fingerprints are generally predictable, fingerprinting can help e-commerce merchants isolate unusual and potentially fraudulent patterns and stop cybercriminals from damaging their business.

3. Knowledge-Based Authentication

When it comes to knowledge-based authentication (KBA), traditional static methods are usually the least effective when it comes to fighting fraud. Questions like “Where did you go to high school” are easy for fraudsters to guess or find the answers to, thanks to the wealth of personal information that can now be found online.

But dynamic KBA improves on this method by creating on-the-fly, time-sensitive questions — like “What was the amount of your mortgage payment last month?” — that are harder for a fraudster to quickly answer but easy for the legitimate customer. Data for these questions is gathered from public records or third-party agencies and is delivered to, but not stored on, an e-commerce merchant’s authentication system.

4. Out-of-Band Identity Proofing

If a customer — or a fraudster — locks themselves out of their account because they’ve mistyped the password too many times, an out-of-band system can call or text the phone number listed on the account and send a temporary password or a verification code that unlocks the account.

Similar to SMS-based verification, out-of-band identity proofing can help a merchant quickly confirm the legitimacy of a customer.

5. IP Geolocation

Geolocation technologies can provide e-commerce merchants valuable information about their customers’ location and connection type, allowing them to confidently authenticate user identity without violating customer privacy. At a granular level, IP data can even accurately pinpoint the location of users at the ZIP code level.

E-commerce merchants can use this technology to peel back the layers of anonymity the internet brings, flag suspicious transactions, and better protect themselves against fraud and cybercriminals.

6. Machine Learning

While simple fraud prevention filters can be effective at reducing fraud levels, they’re also exceptionally vulnerable to savvy fraudsters who find ways around them.

For merchants wanting to employ a robust solution, using advanced artificial intelligence may be one of the most useful tools they can use in the fight against fraud. Not only can it help them reduce false declines and chargebacks, it can also improve the overall customer experience.

When combined with the manual reviews of a team of advanced fraud prevention specialists, machine learning can help e-commerce merchants quickly — and accurately — identify and stop the fraud signals that could compromise a business’s revenue and reputation.

7. Fraud Managed Services

Rather than trying to cobble together a series of fraud prevention technologies, a fraud managed services solution may offer a more comprehensive approach. Choosing a fraud partner with extensive industry and market experience can provide access to a team of fraud experts and the ability to look beyond superficial transaction details and instead see the broader patterns at play.

Frequently Asked Questions

What advanced fraud prevention solutions can ecommerce merchants use?

The post highlights SMS-based verification, device fingerprinting, knowledge-based authentication, out-of-band identity proofing, IP geolocation, machine learning, and fraud managed services. Layering several of these together gives merchants better odds of catching fraud than any single tactic.

How does device fingerprinting help prevent fraud?

Device fingerprinting uses data points like IP addresses, time stamps, operating systems, and browsers, along with reverse geocoding, to uniquely identify a device and narrow a transaction to a physical location. Because normal fingerprints are predictable, it helps merchants isolate unusual patterns and flag potential fraud.

What is the difference between static and dynamic knowledge-based authentication?

Static KBA relies on fixed questions like where you went to high school, which fraudsters can often find online. Dynamic KBA generates time-sensitive questions, such as the amount of last month's mortgage payment, that are hard for a fraudster to answer quickly but easy for the real customer, with data pulled from public records or third-party agencies.

Is SMS-based verification enough on its own?

No. SMS verification sends a one-time password to confirm a customer's identity, but it only works if the customer has their phone when ordering. Merchants should treat it as one layer within a broader fraud prevention strategy rather than relying on it completely.

Why is machine learning valuable for fraud prevention?

Machine learning can help reduce false declines and chargebacks and improve the customer experience, and it adapts better than simple rules that savvy fraudsters learn to bypass. Combined with manual review by fraud specialists, it helps merchants identify and stop fraud signals quickly and accurately.

What is a fraud managed services solution?

A fraud managed services solution offers a more comprehensive approach than assembling separate point tools. Partnering with a provider that has deep industry and market experience gives merchants access to a team of experts who can look beyond surface transaction details to see broader fraud patterns.
