Save KYC Credits

Full document verification costs real money. Pre-KYC blocks bots and fakes before they reach the expensive step.

Instant Response

All 7 checks in one synchronous call. Pre-KYC runs inline before the form submits.

First Line of Defense

AML and KYC can't catch what was never let in. Pre-KYC filters fraud at the earliest, cheapest possible point.

Detection Modules

7 layers. All in one API call.

Every module runs in parallel. One request, one response, all signals combined into a single risk score.

Random Name Detection

Keyboard-mash, repeating chars, and nonsense name sequences blocked at the point of entry.

  • QWERTY pattern detection
  • Repeating char analysis (aaaa, zzzz)
  • Min entropy threshold

Disposable Email Guard

Temporary email domains blocked at signup. Guerrilla Mail, Temp Mail, Mailinator and the rest of the burner ecosystem.

  • Continuously updated blocklist
  • Subdomain variation detection
  • Custom domain blocklist

IP Risk Score

Detect VPN, Tor, datacenter, and residential proxy IPs before the user submits any data.

  • VPN / Tor detection
  • Datacenter IP flags
  • Geo-mismatch scoring

Phone Validation

Validate phone number format, carrier type, and detect VOIP / disposable number services.

  • VOIP / burner detection
  • Carrier type classification
  • Number format validation

Bot Detection

Headless browser, automated form fill, and injection attack patterns detected in real time.

  • Headless browser flags
  • Automated form fill detection
  • Sequential registration patterns

Velocity Control

Block IP addresses or devices that register more than N accounts within a configurable time window.

  • IP-level rate limiting
  • Device fingerprint tracking
  • Configurable thresholds

VAT / TIN Validation

Verify EU VAT numbers via VIES, UK VAT, US EIN, and 50+ global TIN formats with jurisdiction risk scoring.
