VPN & Proxy Detection — SwedenDetect VPN, Proxy & Bot Traffic from Sweden
Maskbreak 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 server-side. No CAPTCHAs.
The networks Sweden traffic actually arrives from
Sweden has 652 autonomous systems on the public registry. 55 of them are hosting, cloud or transit networks holding 15.6M 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.

| AS3301 | TELIANET-SWEDEN Telia Company | 6.5M addresses |
| AS8434 | TELENOR-SE Telenor Sverige AB | 2.6M addresses |
| AS44034 | HI3G | 1M addresses |
| AS29518 | BREDBAND2 | 854K addresses |

Largest hosting-shaped networks registered in Sweden, 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 Sweden traffic needs special scrutiny
Datacenter ASN concentration
Mullvad VPN is headquartered here, and privacy-focused VPN exit nodes cluster in Bahnhof and FS Data ranges.
Residential proxy resale
Consumer ISP ranges in Sweden 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 Sweden. 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 Swedish-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 Sweden traffic
- Every major VPN provider's Swedish exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Swedish IPs
- 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
VPN use & data rules in Sweden
Sweden applies the GDPR under IMY (Integritetsskyddsmyndigheten), and fraud-prevention scoring of Swedish visitors fits squarely within legitimate interest. Sweden's risk profile is shaped by near-total digital payment adoption — Swish transfers and BankID-gated services dominate — which pushes fraud toward account takeover and social engineering rather than card testing. Swedish users are privacy-aware, with meaningful consumer VPN adoption (Mullvad is Swedish), so VPN flags deserve review-not-block treatment, while automation signals against BankID-adjacent flows deserve immediate scrutiny.
