Sentinel scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Denmark. Free API. Under 40ms. No CAPTCHAs.
Why Denmark traffic needs special scrutiny
Datacenter ASN concentration
Denmark is low VPN density but TDC consumer ranges are increasingly cycled through paid residential proxy networks.
Residential proxy resale
Consumer ISP ranges in Denmark 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 Denmark. 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 Danish-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 Denmark traffic
- Every major VPN provider's Danish exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Danish IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Danish geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Denmark
- Country-spoofing — when a session claims to be in Denmark but the network telemetry says otherwise
