Real-World Usage Scenarios

• Phishing-Link Verification - Identify deceptive links where attackers swap Latin characters for Cyrillic or Greek homoglyphs (e.g., using a Cyrillic 'а' instead of a Latin 'a') to mimic legitimate banking or login portals.
• Business Email Compromise - BEC - Prevention - Scan sender display names and email body text in incoming invoices to detect subtle character substitutions often used in wire transfer fraud and executive impersonation.
• Database Integrity - Data Sanitization - Filter out full-width Unicode characters from user inputs that can bypass legacy security filters or cause errors in SQL databases and form processing scripts.
• Brand Reputation - Typosquatting Analysis - Check potential domain names or social media handles for look-alike characters to prevent attackers from registering spoofed versions of your official brand assets.
