What is VPN detection?
VPN detection is a network-enrichment check that estimates whether the client IP belongs to a known VPN, proxy, or hosting range rather than a typical residential ISP.
Why teams want it
Naiza includes VPN and proxy detection in IP enrichment. Combine the network signal with device context and velocity to identify suspicious access and abuse clusters.
False positives
Corporate exit nodes, university networks, and privacy-conscious customers will look like VPNs. Default to REVIEW or extra authentication, not BLOCK, until the fingerprint is listed.
Combine signals
VPN plus new device plus failed logins is stuffing. VPN plus a known-good device and a quiet account is often just travel. Write the rule that way.
Frequently asked questions
Answers about screening, risk signals, and Naiza integration.
What is VPN and proxy detection?
It is IP enrichment that labels an address as likely VPN, proxy, or datacenter so fraud rules can raise scrutiny without treating every such user as an attacker.
Does Naiza detect VPNs?
Yes. Naiza enriches events with VPN and proxy context. Combine those fields with device and velocity signals in fraud rules; the API reference documents the event fields.
Should VPN users be declined for AML screening?
No. AML screening is about the legal name on watchlists. VPN is a fraud-network signal on the session, not a sanctions result.
