Real-time fraud detection that stops VPNs, residential proxies, antidetect browsers, and AI bots — in under 40 ms.

Website · API Docs · Blog · Free API Key

Sentinel is a fraud detection API built for teams who've outgrown IP blocklists.

Modern attackers don't use datacenter VPNs anymore — they rent residential proxies, spoof browser fingerprints with Kameleo/GoLogin, and run automation at scale. Tools built around IP reputation (IPQS, SEON, Sift) miss ~70% of that traffic.

Sentinel combines network analysis with device fingerprinting to catch what they can't:

• 🏠 Residential proxy detection — BrightData, Smartproxy, IPRoyal, ShadowNode
• 🎭 Antidetect browser tampering — Kameleo, GoLogin, AdsPower, Multilogin
• 🤖 Bot & automation detection — Puppeteer, Playwright, Selenium, agentic AI
• 🆔 Persistent visitor ID — survives incognito, VPN switching, cookie clears
• 🌍 <40 ms p95 globally — runs in your critical path without slowing it down

• 1,000 API requests per hour
• No credit card required
• Full feature access (not a gimped free tier)
