Side-by-side comparison of AI visibility scores, market position, and capabilities
Sift is a digital trust and safety platform using machine learning to detect and prevent fraud across account takeover, payment fraud, and content abuse.
About
Sift is a digital trust and safety platform that applies machine learning to detect and prevent fraud across multiple attack vectors — account takeover, payment fraud, fake account creation, content spam, and promotion abuse — using a global network of behavioral signals drawn from events across its customer base to continuously improve detection models. The platform's Global Data Network aggregates anonymized fraud signals from thousands of businesses, enabling machine learning models to detect emerging fraud patterns across the network before they reach any individual merchant, providing a threat intelligence advantage that improves as more companies contribute event data. This network effect model creates a compounding detection capability that individual companies cannot replicate with solely their own transaction history.
