VPN & Proxy Detection — FinlandDetect VPN, Proxy & Bot Traffic from Finland
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Finland. Free API. Under 40ms server-side. No CAPTCHAs.
The networks Finland traffic actually arrives from
Finland has 294 autonomous systems on the public registry. 32 of them are hosting, cloud or transit networks holding 11.4M addresses between them — the ranges a commercial VPN or datacenter proxy exits from. Residential broadband is the rest, and that is the traffic worth watching, because a residential proxy hides inside it.
| ASN | Network | IPv4 space |
|---|---|---|
| AS719 | ELISA-AS ELISA OYJ | 3.7M addresses |
| AS1759 | TSF-IP-CORE Telia Finland Oyj | 3.3M addresses |
| AS16086 | DNA | 1.9M addresses |
| AS1741 | FUNETAS | 610K addresses |
| AS200656 | NOKIA-EMEA | 203K addresses |
| AS29422 | NBLNETWORKS-AS Telia Cygate Oy | 151K addresses |
| AS41701 | CAP-FIN-AS | 133K addresses |
| AS1926 | UTANET-AS | 131K addresses |
Largest hosting-shaped networks registered in Finland, by IPv4 allocation. Registry data, refreshed daily. A datacenter ASN is not evidence of fraud on its own — it is one signal, weighed alongside device and behaviour.
Why Finland traffic needs special scrutiny
Datacenter ASN concentration
Hetzner Helsinki and UpCloud datacenter ranges drive nearly all Finnish VPN exit traffic.
Residential proxy resale
Consumer ISP ranges in Finland 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 Finland. Maskbreak 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 Finnish-targeted SaaS, fintech, and e-commerce increasingly uses Kameleo, GoLogin, or AdsPower to spoof device fingerprints. Maskbreak scores these at the device layer, not the IP layer.
What Maskbreak detects for Finland traffic
- Every major VPN provider's Finnish exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Finnish IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Finnish geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Finland
- Country-spoofing — when a session claims to be in Finland but the network telemetry says otherwise
