Country-level control in milliseconds
Every request resolves to a country and region in milliseconds, with no extra lookup on your side. Build allowlists for the markets you serve and challenge or block traffic from regions you don't.
- Country & region resolution — every request is resolved to a country and region in milliseconds with no extra lookup on your side.
- Allow, challenge or block — build allowlists for the markets you serve and apply tighter policies to high-risk regions.
Stop campaign-driven attacks
Most large-scale abuse originates from a small set of regions and rotates through them quickly. Geographic rules let you cut off entire attack waves while keeping legitimate users in your target markets unaffected.
- Cut off attack waves — block entire regions during a campaign so abuse stops at the edge instead of inside your application.
- Keep target markets unaffected — regional rules leave your real customers untouched while traffic from rotating sources is filtered out.

How accurate is IP geolocation?
Country-level IP geolocation is highly reliable and is what geographic policies are built on. CaptchaFox resolves every request against continuously updated network data and pairs it with proxy and VPN detection, so attempts to spoof location through anonymizing networks are flagged.
Can I block traffic from specific countries?
Yes. CaptchaFox resolves every request to a country and region in milliseconds and lets you allow, challenge or block traffic per country. Build allowlists for the markets you serve and tighter policies for high-risk regions.
Does geo-blocking help with compliance?
Yes. Geographic policies let you prevent access from sanctioned or out-of-market regions at the edge, which helps you meet regional regulations without building enforcement into your own application.
What if attackers use a VPN to fake their location?
Geolocation works together with CaptchaFox proxy and VPN detection. Requests that hide behind anonymizing networks are flagged separately, so location spoofing through VPNs or proxies doesn't bypass your geographic rules.
Do I need a separate geolocation lookup service?
No. Country and region resolution is built into every CaptchaFox verification with no extra lookup, latency or per-query fees on your side.
