O-PLUX Features

O-PLUX analyzes orders in real-time using multiple factors to detect any suspicious elements.

  • Shared Negative Data: Finding matches with the negative database shared among user companies.
  • Normalization: Normalizes variations in address and name formats, allowing for detection of similar order entries and address data matching.
  • Device Information: Detects and analyzes IP addresses, cookies for device matching, international access, language settings, and time zones to help identify potential fraud.
  • Email Validation: Verifies email sendability, detects alias and disposable email domains, and identifies suspicious domains.
  • External DB Linkage: Connects with IP-Geolocation, checks phone connectivity status (in development), with further integrations planned.

Utilizing these features, O-PLUX conducts real-time assessments through plugins, with processing times of approximately one second.
