VPN & Proxy Detection — PolandDetect VPN, Proxy & Bot Traffic from Poland
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Poland. Free API. Under 40ms server-side. No CAPTCHAs.
The networks Poland traffic actually arrives from
Poland has 2,139 autonomous systems on the public registry. 60 of them are hosting, cloud or transit networks holding 13.9M 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.

Largest hosting-shaped networks registered in Poland, 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 Poland traffic needs special scrutiny
Datacenter ASN concentration
Antidetect-browser-driven account fraud is growing rapidly, primarily via Orange Polska consumer ranges.
Residential proxy resale
Consumer ISP ranges in Poland 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 Poland. 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 Polish-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 Poland traffic
- Every major VPN provider's Polish exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Polish IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Polish geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Poland
- Country-spoofing — when a session claims to be in Poland but the network telemetry says otherwise
