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