Sentinel scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Mexico. Free API. Under 40ms. No CAPTCHAs.
Why Mexico traffic needs special scrutiny
Datacenter ASN concentration
Mexico is Telmex consumer IPs are heavily abused in residential proxy networks targeting US-facing SaaS platforms.
Residential proxy resale
Consumer ISP ranges in Mexico 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 Mexico. 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 Mexican-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 Mexico traffic
- Every major VPN provider's Mexican exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Residential proxy networks reselling consumer Mexican 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 Mexican geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Mexico
- Country-spoofing — when a session claims to be in Mexico but the network telemetry says otherwise
