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