VPN & Proxy Detection — EstoniaDetect VPN, Proxy & Bot Traffic from Estonia
Sentinel scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Estonia. Free API. Under 40ms. No CAPTCHAs.
Why Estonia traffic needs special scrutiny
Datacenter ASN concentration
Estonia is home to Sentinel — small market but high concentration of crypto-targeted VPN traffic via Telia and Elisa ranges.
Residential proxy resale
Consumer ISP ranges in Estonia 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 Estonia. 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 Estonian-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 Estonia traffic
- Every major VPN provider's Estonian exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Residential proxy networks reselling consumer Estonian 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 Estonian geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Estonia
- Country-spoofing — when a session claims to be in Estonia but the network telemetry says otherwise
