Prynt identifies VPNs, proxies, Tor nodes, and datacenter IPs in real time using multi-signal analysis. Know when users are masking their true location -- without blocking legitimate privacy users.
Prynt doesn't just flag "VPN or not" -- it classifies the exact anonymization type, provider, and risk level so you can make intelligent decisions.
Major consumer VPN services used by millions. While often used for privacy, they're also used to bypass geo-restrictions and mask fraudulent activity.
Traffic routed through real residential IPs, making it appear to come from legitimate homes. The hardest anonymization method to detect -- and the most abused by fraudsters.
IPs hosted in cloud infrastructure and datacenters. These aren't residential connections -- they're servers pretending to be users. Common in scraping and automated fraud.
Traffic routed through the Tor onion network. Exit nodes are publicly listed, but new relays appear constantly. Prynt tracks the full Tor directory in real time.
General-purpose proxy protocol supporting any traffic type. Commonly used in credential stuffing tools and account checkers due to their speed and flexibility.
HTTP/HTTPS proxies that strip identifying headers and mask the original IP. Used for web scraping, ad verification, and circumventing access controls.
Every request passes through a multi-stage analysis pipeline that combines IP intelligence with behavioral and environmental signals.
Every identification returns a detailed VPN/proxy result. Use the structured fields to make nuanced decisions -- not just block/allow.

} VPN detection isn't about blocking privacy -- it's about understanding risk when location is material to the decision.
Detect when login attempts come from VPNs or proxies that don't match the user's established location pattern. Trigger step-up authentication when risk is elevated -- not on every login.
Enforce geographic licensing agreements and content distribution rights. Know when users are circumventing regional restrictions with VPNs -- essential for streaming, gaming, and regulated content.
Flag transactions where the payment IP doesn't match the billing country or where VPN/proxy usage correlates with stolen card usage patterns. Reduce chargebacks without increasing friction for legitimate buyers.
Satisfy regulatory requirements by detecting when users access services from sanctioned regions while masking their location. Critical for fintech, crypto, and online gambling platforms operating under strict jurisdictional rules.
Most VPN detection tools rely solely on IP databases. Prynt combines IP intelligence with behavioral analysis, timezone validation, and WebRTC probing for unmatched accuracy.
