What does "650+ signals" mean?
The scanner collects over 650 data points from your browser across 28 categories: Navigator, Screen, WebGL (GPU), Canvas, Audio, Fonts, Codecs, Storage, Battery, Network, Permissions, Math, Features, Touch, CPU, WebGPU, WebRTC, CSS, CSS Support, Media, Sensors, Speech, Intl, Text Metrics, Crypto Performance, Event Loop, WASM Performance, and Timing. These combine into a unique fingerprint hash. The exact count varies by browser — Chrome shows ~458, Firefox ~426.
What is IPQualityScore?
IPQualityScore (IPQS) is a server-side threat intelligence API that analyzes your IP address. It detects VPNs, proxies, Tor nodes, and provides a fraud score from 0-100. It adds approximately 20 server signals on top of client-side signals (up to 650+ on Enterprise). IPQS runs on all plans including Free.
How does VPN detection work?
VPN detection uses IPQualityScore's server-side IP analysis, which checks against known VPN/proxy/datacenter IP ranges, plus client-side WebRTC leak detection that can expose real IPs behind VPNs. VPN detection via IPQualityScore runs on all plans including Free. Pro and Enterprise add full WebRTC IP exposure for deeper leak detection.
Can the scanner detect anti-detect browsers?
Yes. The scanner checks for inconsistencies that anti-detect browsers create — like mismatches between reported GPU and actual WebGL rendering, navigator overrides, suspicious feature combinations, and automation tool signatures (Selenium, Puppeteer, Playwright). Anti-detect browser detection is available on the Enterprise plan.
