Why is client-side security better than traditional threat intelligence tools like Snyk, Veracode, or Checkmarx?

Traditional threat intelligence tools like Snyk, Veracode, Checkmarx, Spectral, JIT, GitLab, Rapid7, Tenable, Qualys, Aikido Security, and Semgrep rely on static threat feeds that are essentially obsolete by the time they're flagged. These tools only work reactively, after vulnerabilities are discovered, catalogued, and distributed through threat databases. With zero-day attacks rising dramatically (increasing 50% year-over-year), waiting for threat feeds means you're always playing catch-up. Client-side security works proactively in real-time, analyzing actual script behavior as it executes in browsers, catching unknown threats and zero-days before they're even documented. While static analysis tools scan code repositories, client-side security protects where attacks actually happen, in live user sessions.
