Why Argentina traffic needs special scrutiny
Datacenter ASN concentration
Argentina is a top regional source of residential-proxy-masked subscription fraud, particularly Telecentro and Claro ranges.
Residential proxy resale
Consumer ISP ranges in Argentina 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 Argentina. 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 Argentine-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 Argentina traffic
- Every major VPN provider's Argentine exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Argentine IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Argentine geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Argentina
- Country-spoofing — when a session claims to be in Argentina but the network telemetry says otherwise
