▸ REAL-TIME THREAT DETECTION
• Phishing detection — catches brand impersonation, suspicious domains, and URL shortener obfuscation
• JavaScript injection blocking — detects XSS payloads, script tags, event handlers, and encoded attacks
• SSL certificate verification — inspects the actual certificate, extracts organization, country of origin (with flag), issuer, and expiration date
• Domain trust verification — unknown domains start as suspicious until SSL is verified
• EMV payment QR validation with CRC-16 checksum integrity
