ZeroThreat Mobile Security Architecture implements a four-layer threat detection pipeline that intercepts URLs from notification listeners, browser intents, and manual scans. Input surfaces feed into URL handling and pre-processing, which normalizes URLs and extracts redirect targets before passing to a multi-method detection engine. The detection engine combines DNS verification, blacklist matching, whitelist checks, typosquatting similarity analysis, and URL pattern heuristics to compute a 0-100 threat score and classify URLs as safe, suspicious, or phishing. Real-time alerts with actionable responses (continue, block, or allow domain) are generated and logged to a local database that feeds back into pre-checks for continuous learning. Fork this diagram to customize detection rules, add provider-specific integrations, or adapt the pipeline for web or desktop security applications.
