Spur Intelligence

Data service that classifies IP addresses as VPNs, residential proxies, or other anonymization services.

Spur maintains intelligence on anonymization infrastructure, letting fraud and security teams check whether traffic comes from a VPN exit, residential proxy network, or similar service. Its API and feeds support fraud prevention, account security, and investigations. Founded in 2017 and bootstrapped for years, it took growth investment from Insight Partners in 2026.
