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
Abuse clusters hide on cheap VPNs. Geo-restricted products also care. Naiza product copy includes VPN detection on event enrichment.
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
Short answers written so search and answer engines can cite them.
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. Public feature copy includes VPN detection as part of IP enrichment. Confirm fields in the current API docs.
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.
