VPN & Proxy Detection — IndiaDetect VPN, Proxy & Bot Traffic from India
Sentinel scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from India. Free API. Under 40ms. No CAPTCHAs.
Why India traffic needs special scrutiny
Datacenter ASN concentration
India is massive scale of low-cost residential proxies sourced from Jio and Airtel consumer connections.
Residential proxy resale
Consumer ISP ranges in India are routinely sold through residential proxy networks like ShadowNode and Bright Data. These IPs look real but rotate every few minutes — a clear bot signature once you know what to look for.
VPN exit-node clustering
The same handful of hosting providers dominate VPN exit nodes in India. Sentinel maintains live mappings of these ranges so a new IP from a known VPN ASN is flagged within seconds of going live.
Antidetect browser usage
Multi-accounting fraud against Indian-targeted SaaS, fintech, and e-commerce increasingly uses Kameleo, GoLogin, or AdsPower to spoof device fingerprints. Sentinel scores these at the device layer, not the IP layer.
What Sentinel detects for India traffic
- Every major VPN provider's Indian exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Residential proxy networks reselling consumer Indian IPs (ShadowNode, Bright Data, Smartproxy, Oxylabs)
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Indian geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from India
- Country-spoofing — when a session claims to be in India but the network telemetry says otherwise
