Sift

Machine-learning fraud prevention across payments, accounts, and content abuse.

Visit website
Visit website sift.com

Overview


Sift is a fraud prevention platform using machine learning across payments, account access, and content, informed by signals from a large customer network.

It covers payment fraud scoring, account-takeover detection, spam and content abuse, and chargeback representment. Scores are returned in real time and can trigger automated decisions or route to manual review. Because decisions are model-driven, individual outcomes are less directly explainable than rule-based systems.

Common use cases


  • Score payment transactions for fraud in real time
  • Detect account takeover attempts at login
  • Block spam and abusive content submissions
  • Automate decisions with a manual review fallback

Key features


  • Machine-learning scoring across the full user journey
  • Payment fraud, account takeover, and content abuse
  • Global data network improving model signal
  • Automated decisioning with review workflows
  • Chargeback representment support
  • Real-time API scoring
