Fraud Hides Behind Legitimate-Looking Signups.

Digital businesses depend on open registration flows to drive growth, but those same flows are a primary entry point for abuse. As attackers automate account creation and distribute activity across anonymized networks, basic signup controls struggle to separate real users from coordinated fraud.

Spur provides infrastructure-level visibility that strengthens fraud and identity controls at registration, reducing downstream abuse without sacrificing conversion.

How Spur Stops Fraud at Signup.

Spur reveals the anonymized infrastructure behind account creation, enabling fraud and identity teams to selectively block, challenge, or allow signups based on real infrastructure risk.

Identify fraudulent account creation attempts routed through residential proxies, VPNs, and other anonymizing infrastructure used to scale signup abuse.

Detect proxy-backed signup abuse

Identify fraudulent account creation attempts routed through residential proxies, VPNs, and other anonymizing infrastructure used to scale signup abuse.

Stop fraud before accounts exist

Evaluate infrastructure risk during registration, allowing teams to block, challenge, or step up verification before fraudulent accounts are created and weaponized.

Protect conversion with low false positives

High-fidelity detection minimizes disruption to legitimate users, reducing unnecessary friction while still stopping high-risk signups.

Make real-time decisions at scale

Spur delivers reliable enrichment through APIs and session-level enrichment, enabling inline signup decisions in high-volume registration workflows.

Attribute fraud to real infrastructure

Go beyond generic “risky IP” flags with visibility into proxy networks and services used to generate fake accounts, whether evaluated in real time or across historical datasets using on-prem data feeds.

Support defensible enforcement

Every classification is backed by transparent, verifiable attributes rather than opaque scoring, making signup enforcement explainable across fraud, security, and compliance teams.
