Identify fraudulent online activities

Prevent online fraud while ensuring a frictionless customer experience

Globally each year, tens of billions of dollars are lost to online fraud. Traditionally, companies used rule-based fraud detection applications that aren't accurate enough and can’t keep up with the changing behaviors of fraudsters. With AWS Fraud Detection machine learning solutions, companies can proactively and more accurately detect and prevent online fraud. These solutions will help reduce revenue losses, avoid brand damage, and provide a frictionless customer online experience while adapting to changing threat patterns.

Use cases

Payment or transaction fraud detection

The event of interest is an attempt to complete an online purchase or make or process a payment online. One common example in the e-commerce space relates to a “guest checkout”. The transaction involves a user who does not have account history or has selected a “guest” checkout option for a more anonymous experience.

New account fraud

The event of interest is the act of signing up or registering for a new account. Fraud starts when a bad actor creates a fake, stolen, synthetic identities, or generate multiple accounts, often through the use of bots. Once identity is established on a digital platform, executing an attack is easier.

Account takeover

The event of interest is a login attempt for a legitimate user account. Account Takeover refers to the situation where a legitimate user’s login has been compromised, either because a bad actor has stolen their userid and password, purchased them on the dark web, or managed to guess it.

Promotion abuse

The event of interest is typically the act of a user redeeming a benefit granted via a demand generation or marketing promotion. Bad actors will access a legitimate user’s account and drain loyalty credits or points via transfer or purchase. They will also create multiple fake accounts to exploit promotions such as a free trial or free credits that come with a new account, or perform a self-referral to get a referral bonus.

Fake or Abusive Reviews

The event of interest is the posting of a product review which may contain misleading or abusive content. Automating screening is critical for scaling the ability to spot fake and abusive reviews so that customer service teams don’t have to wade through mountains of alerts, many of which may be false positives.

"Twelve months ago, we were looking for a fraud detection solution that didn’t require us to invest heavily in our own machine learning expertise. With transparent pay-as-you-use pricing, Amazon Fraud Detector helped us to easily create and incorporate an effective and affordable new machine learning model into our existing setup."

Richard Fisher, Head of Technology at SLA Digital


FlightHub Group

FlightHub Group makes travel accessible, allowing more people to visit new places and explore new cultures. With over 5 million customers served per year, their goal is to provide travelers with the cheapest flights available, along with optimal itineraries and exceptional customer service. One of the highest priorities for FlightHub's Fraud Prevention team is discerning a value-conscious traveler seeking an affordable airline ticket from fraudsters seeking to buy tickets with stolen credit cards.

"Since introducing Amazon Fraud Detector, our abort rate has dropped below 2% (vs. 5% previously). Additionally, our chargeback rate is the lowest it’s ever been since the company’s inception. The business can now accept more checkouts that our past models would have flagged as risky and turned away. But perhaps the best thing is we’re getting these great results with roughly the same operational costs as before. All of this results in an increased number of bookings and revenues, along with a decrease in losses due to chargebacks."

Drayton Williams, Fraud Investigations Manager at FlightHub


Aella Credit

“Identity verification and validation have been a major challenge in emerging markets. The ability to properly identify users is a key hindrance in building credit for billions of people in emerging markets. Using Amazon Rekognition for identity verification on our mobile application has reduced verification errors significantly and given us the ability to scale. We can now detect and verify an individual’s identity in real time without any human intervention, thereby allowing faster access to our products. We tried various well-advertised solutions, but none of the popular alternatives could accurately map out various skin tones. Amazon Rekognition helped us effectively recognize faces of our customers in our markets. It also helped us with KYC in discovering overlapping profiles and duplicate datasets.”

Wale Akanbi, CTO & Co-Founder - Aella Credit



“In Q1/Q2 2020 we experienced a spike in accounts being used for phishing attacks. As a result, we needed to supplement our existing homegrown solution with stronger transaction data and signals to identify bad actors sooner. A scalable solution based on predictive machine-learning was important to us as a growing business ourselves. Amazon Fraud Detector made it easy to build a model using our own data that accurately identifies account signups that result in phishing attacks. More importantly, we were able to get these results with a very low false positive rate, which means no additional work for our operations staff. Amazon Fraud Detector has a competitive pricing model and we can easily integrate the model into our existing workflow.”

"With Amazon Fraud Detector, we reduced fraudulent transactions by 6%. At the same time, we’ve been able to automate checkout fulfillment on more than 90% of the transactions that would have previously been flagged for manual review. Now, we’re manually reviewing less than 1% of our transactions—down from 10%. Since we implemented this service, we’ve seen a significant improvement in our Trustpilot score, and we know it’s a result of this checkout detection automation, as well as additional enhancements we are consistently making on the website. Trust is a big part of our value to customers, so that’s a huge win for our business.”

"Amazon Fraud Detector has enabled us to drastically improve operations, increase our flexibility to respond to bad actors, and have greater control of systems and processes. Initially, we were exploring an in-house and 3rd party solution. When Amazon Fraud Detector was announced, we immediately changed course. We have been an AWS customer for many years and have great trust in Amazon’s products. With Amazon Fraud Detector, we are no longer bound by the conventional limitations of on-premise or SaaS offerings. Instead, we have the flexibility to adapt a Machine Learning powered service to meet our needs and the ability to use AWS’s rules-only option while easily scaling to full Machine Learning capabilities when needed. This saved Truevo 3-6 months in development! In fact, we deployed our first prototype model within 30 minutes. Overall, we are operating with greater confidence in our ability to detect fraud in real-time. We are better equipped to deploy rule detections when we notice odd activity that we may not fully understand, but need to stop. We are able to respond and adapt to ever-changing regulatory and scheme requirements allowing us to stay on top of our game.”
