Sift (formerly Sift Science) is the San Francisco-based Digital Trust and Safety platform that protects more than 700 global brands from payment fraud, account takeover, content abuse, promotion abuse, and money movement risk. Sift's APIs ingest user, device, payment, content, and verification events, return real-time risk scores per abuse type, automate decisions through Workflows, ship a Verification API for step-up challenges, and operate a Console for analyst case management. Sift was founded in 2011, processes more than one trillion events per year, and reports a median annual loss prevented of about $4.2M per customer.
