The Indian Threat Landscape

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 can appear in commercial or peer-to-peer residential proxy pools. A consumer ISP label is not proof of fraud; combine it with device, session, and routing signals.

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.

How Sentinel Helps

What Sentinel detects for India traffic

Every major VPN provider's Indian exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
Commercial or peer-to-peer residential proxy pools using consumer Indian IPs
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

Local Context

VPN use & data rules in India

India's DPDP Act (Digital Personal Data Protection Act, 2023) established the country's first comprehensive data-protection regime, with security and fraud-prevention processing accommodated under its "legitimate uses" provisions. India's mobile-first scale shapes the fraud profile: OTP interception, SIM-swap-driven account takeover, and incentive/referral abuse at volumes few other markets see. CGNAT is ubiquitous on Indian mobile networks — many legitimate users share single IPs — so IP-reputation alone produces brutal false-positive rates there. Device-layer identification is not optional for Indian traffic; it's the only signal that survives carrier-grade NAT.

5-Minute Integration

One API call. Bearer token. Done.

        // Score any session — country-level signals included

        const r = await fetch('https://sntlhq.com/v1/evaluate', {

          method: 'POST',

          headers: { 'Authorization': 'Bearer sk_live_...' },

          body: JSON.stringify({ token: sentinelToken })

        });

        const { decision, country, network } = await r.json();

        if (country === 'IN' && network.vpn) blockOrChallenge();
