VPN & Proxy Detection — CanadaDetect VPN, Proxy & Bot Traffic from Canada
Sentinel scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Canada. Free API. Under 40ms. No CAPTCHAs.
Why Canada traffic needs special scrutiny
Datacenter ASN concentration
Canada is frequent target for cross-border SaaS account abuse, with OVH Beauharnois ASN being a top fraud origin.
Residential proxy resale
Consumer ISP ranges in Canada 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 Canada. 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 Canadian-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 Canada traffic
- Every major VPN provider's Canadian exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Residential proxy networks reselling consumer Canadian 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 Canadian geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Canada
- Country-spoofing — when a session claims to be in Canada but the network telemetry says otherwise
