Data Power

Apps worldwide send data in real-time to Sift Science using our modern REST APIs & JavaScript snippet.


Actions speak louder than words.

Send us a record of key activities that happen on your site as they happen using our API and JavaScript snippet. The more you share the better we can predict fraud.

Key activities include when: orders are submitted, user accounts are created and updated, users login and logout, items are added to a shopping cart, user-generated content is submitted, messages are sent, and much, much more.

The anti-fraud ring.

Joining Sift Science is like joining an anti-fraud ring. Or a league of extraordinary fraud fighters. Or an elite fraud prevention network. Or ... well, we think you get the idea. Bottom line is, you're not alone in the fight against fraud.

With Sift Science, you benefit from all the clues, signals, and patterns fraudsters have left behind anywhere on our network. We anonymize and secure everything - then make sure fraudsters can't strike twice.

One stop shop.


Sift Science partners with multiple 3rd party data providers to help us keep track of social media profiles, disposable email domains, IP address geolocations, and other interesting factoids.

Machine learning at scale.

What makes Sift Science's machine learning so special? While we take pride in our algorithms, the true benefit to our customers is the speed and scale at which we operate.

At Sift Science we update our machine learning models in real-time, literally. And we're collecting over 40 million new clues each day! For perspective, most machine learning solutions update their models once per month and are probably taking in a couple hundred data points per day.

Feature extraction (much less painful than it sounds)

Based on years of experience and fine tuning, Sift Science has mastered the art of feature extraction. That means that we can take in wide variety of data input and extract the most meaningful and actionable insights out of each data point. Long story short, this is part of our secret sauce that allows us to analyze 5,000+ fraud signals.

Suspicious signals, aka clues, revealed in their entirety

Want to know why a user's Sift Score is 87? We believe in transparency, not smoke and mirrors. That's why we list out every suspicious signal and how much each signal contributed to a Sift Score.

Details, Details, Details

If you like digging into the details, then Sift Science is for you! We've got all the details you need to investigate every case from every possible angle. Look into social media profiles, geolocation history, and even see how different users are connected (e.g. share the same device, cookie, address, etc) with our slick Network Visualization feature.

Congrats! You're officially a supervisor.


OK, so we can't give you a promotion. But, we do need you to be a supervisor. See, we use supervised machine learning, and that means that our software actually learns from the feedback you give us. Pretty cool, eh? Here's the deal: we do great things on our own, but with your input we can do amazingly awesome things! And that's better than great, right?
