Know if that IP is hiding something.
Detect VPNs, proxies, Tor exit nodes, and hosting providers from any IP address — plus a threat score and fraud score, in a single API call.
Trusted by teams at
VPN, proxy, Tor, and hosting detection in one lookup.
VPN & Proxy Detection uses the IP2Proxy database to flag VPN providers, public and web proxies, Tor exit nodes, and data-center or hosting IPs. ASN organization data comes from a separate MaxMind database. Both IPv4 and IPv6 are fully supported.

Built for fraud and risk workflows.
VPN & Proxy Detection fits anywhere IP-based trust matters — signup, auth, bots, and compliance alike.
Score risk at signup
Flag or block registrations coming from VPN, proxy, or Tor IPs — a strong signal for fraud farms and fake account creation.
Add risk signals to authentication
Trigger step-up authentication (MFA) when a login attempt comes from a flagged proxy or Tor exit node.
Detect bots and crawlers
Hosting and data-center IPs correlate strongly with bots and scrapers. Flag or rate-limit traffic from these ranges automatically.
Meet compliance and regulatory checks
Regulated services can require confirming that requests aren't coming through anonymizing infrastructure before granting access.
Prevent geo-blocking circumvention
Detect users masking their real location with a VPN or proxy to access geo-restricted content or pricing.
Enrich fraud models with a single score
Combine the fraud score and threat level with other signals — device, card, email — into a composite fraud model per request.
Use together with complementary APIs.
VPN & Proxy Detection works even better when paired with other Requiems APIs.
Cross-reference IP threat signals with the card's issuing country to catch mismatched, high-risk payment attempts.
Layer IP-based threat scoring with ASN, ISP, and hosting-provider data to flag datacenter and proxy traffic with more confidence.
Combine anonymized-IP detection with disposable email checks to catch fake account creation at signup.
