Browser intelligence beyond what cookies can provide

Cryptographic Fingerprinting

THE PROBLEM

Why Cookies Are Deprecated

Cookies were never designed for modern tracking needs

Security Failures

  • XSS Attacks
    Malicious JS can steal cookie data instantly
  • Session Hijacking
    Stolen cookies replay from anywhere
  • CSRF Exploits
    Cookies auto-sent with cross-origin requests
  • Easily Forged
    Users can edit or delete cookies at will

Reliability Crisis

  • Browser Auto-Delete
    Safari ITP & Firefox ETP delete cookies in 7-30 days
  • 3rd-Party Blocking
    All major browsers now block third-party cookies
  • Ad Blocker Epidemic
    45% of users run ad blockers that strip cookies
