VPN detection, answered
How does VPN detection work?
Sentinel inspects every request against continuously updated intelligence on commercial VPN ranges, datacenter ASNs, and Tor exit nodes, and layers device and behavioural signals on a live session to expose residential-proxy and antidetect traffic a plain IP feed misses. Each visitor is scored in under 40ms — without blocking legitimate users.
Can Sentinel detect residential proxies?
Yes. Residential proxies — including commercial and peer-to-peer residential networks — are detected through ASN classification, behavioral fingerprinting, TCP/TLS anomalies, and an internal reputation graph. Treat the result as one risk signal and validate it against your own traffic.
Which countries are covered?
Sentinel provides country-specific intelligence for 30+ jurisdictions including the United States, United Kingdom, Germany, France, India, Brazil, Japan, South Korea, UAE, Australia, and every EU member state. Coverage extends to every IANA-assigned IP range globally.
How fast is the detection API?
Server decision time is under 40ms at the median, and Cloudflare's global edge network fronts the API — the scanner's first-pass verdict is answered directly at the edge.
Is there a free tier?
Yes. Free tier: 1,000 requests/hour. No card, no expiry. Higher sustained volume is available on the Growth and Enterprise plans — see pricing.
Does VPN detection block privacy-conscious users?
No. Sentinel returns a risk score — not a block decision. Platforms choose the threshold: many allow VPN traffic on public pages but require step-up verification at signup or checkout. This removes fraud without alienating privacy-aware customers.
