Traditionally, preventing online fraud relied on point-in-time proof of identity: enter the correct password, complete a biometric verification, or pass a liveness check, and gain access. To defeat these controls, fraudsters had to steal credentials and other identity evidence from a real user, which was difficult to execute and scale. Today, widespread access to AI enables fraudsters to fabricate or imitate legitimate identities by combining exposed credentials with synthetic media designed to evade identity verification. Consequently, identity checks are no longer sufficient as they capture a moment in time. Even when someone passes a check, it does not mean the account itself can be trusted.
One convincing interaction can be faked. A consistent pattern of legitimate behavior is much harder to manufacture. Modern fraud prevention must move beyond stateless decisions toward a stateful trust model. Traditional identity verification asks, “Can this person pass the check right now?” A stateful approach additionally asks, “Does it fit what we know about this account and its established behavior?” At Cloudflare, trust is continually earned and reassessed at each interaction against historical behavioral, network, and device patterns.
Cloudflare’s Account Abuse Protection (AAP) creates stateful account overviews to help website owners detect and investigate abuse across login and signup activity. Customers configure an identifier from their existing login or signup flow, such as an email address, username, or phone number. Cloudflare cryptographically hashes that value to create a privacy-preserving, per-domain Hashed User ID. Within AAP, a Hashed User ID represents an account and anchors its activity. With each login or signup, AAP adds the event and relevant network and device signals observed at Cloudflare’s edge. Over time, this accumulated history establishes context for the account’s typical behavior, making meaningful deviations easier to identify and giving fraud teams (i.e., the designated personnel for Security Intelligence, Investigations, Trust & Safety, or Risk & Compliance) a stronger foundation for investigation.
Today, we are introducing a new fraud dashboard for Account Abuse Protection, available first to Early Access customers. The workspace brings together account overviews built from acti
