VPN detection, answered
How does VPN detection work?
Sentinel inspects every request against a continuously updated registry of commercial VPN ranges, datacenter ASNs, residential proxy networks, and Tor exit nodes. Each IP gets scored in under 40ms on 400+ device-level signals, network characteristics, and historic abuse patterns — without blocking legitimate users.
Can Sentinel detect residential proxies?
Yes. Residential proxies — including Bright Data, Smartproxy, IPRoyal, and shadow networks like Shadownode — are detected through ASN classification, behavioral fingerprinting, TCP/TLS anomalies, and an internal reputation graph. Detection exceeds 94% for major residential proxy providers as measured in Q1 2026.
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?
Median response time is under 40ms from any region thanks to edge deployment across six continents. P99 latency stays below 120ms even during traffic spikes.
Is there a free tier?
Yes. The free tier includes 1,000 API requests per hour with no credit card required. Production plans scale from 100,000 to 10 million requests per month.
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.
