Sift

Sift is an AI-driven fraud prevention platform that helps enterprises detect and block payment fraud, account takeover, fake account creation, and content abuse in real time. Used by over 700 brands, including Hertz, Yelp, Poshmark, and Patreon, Sift processes more than 1 trillion events annually from its global data network, giving fraud teams the intelligence they need to approve more legit customers while stopping bad actors. The platform covers the entire consumer journey—from signup and login through transactions and post-transaction activity—so you can apply consistent risk decisions at every touchpoint. Core products include Payment Protection, Account Defense, and the Sift Score API, each designed to address specific fraud vectors. Payment Protection focuses on approving more transactions while minimizing chargebacks, while Account Defense stops account takeover before it turns into revenue loss. The Sift Score API lets developers integrate Sift's machine learning into their own risk models, enabling custom decisioning without building from scratch. Sift's decisioning engine lets you build rules and adapt risk strategy in real time, and its automation and workflows handle routine fraud ops work, routing cases, and repetitive tasks, freeing analysts to focus on high-priority investigations. The platform emphasizes transparency via Clearbox, which provides visibility into the signals, models, and workflows behind every decision, so you can tune automation with confidence rather than relying on a black box. Pre-built workflow templates and expert services help teams scale and refine their fraud strategies. Sift is built for high-growth digital businesses—e-commerce, fintech, iGaming, travel, and SaaS—that need scale and real-time decisioning. Its network intelligence means new-to-you users often have prior context, reducing the time to accurate decisions. Compared to competitors like Forter or Kount, Sift differentiates with Clearbox transparency and FIBR benchmarking.
