How do I detect if a visitor is using a VPN or proxy?

Look the address up and read its network posture. We resolve the ASN and organisation and match against hosting providers, commercial VPN egress and live Tor exit nodes, returning each signal plus a composite score so you know when someone is masking their origin.

Can I block bots and datacenter traffic at signup?

Yes — datacenter and hosting ASNs are the strongest anonymity signal, and surfacing them on the registration path lets you gate abuse, throwaway signups and scripted traffic before they pollute your funnel or your free tier.

How often is the VPN and Tor data refreshed?

Tor exit nodes and commercial VPN ranges shift constantly, so that data is refreshed hourly. A stale anonymity list is worse than none, because it gives false confidence.

Bot & VPN detection — Locale Sense

Not every visitor is a customer. Identify requests coming from hosting providers, commercial VPNs and Tor exit nodes, and fold that into a risk score — to protect signups, gate abuse and keep your funnel metrics honest.
