What is Cookie Security Analysis?

Cookie security analysis checks whether your website sets cookies with proper security flags: HttpOnly (prevents JavaScript access), Secure (HTTPS-only transmission), and SameSite (CSRF protection). Missing flags expose users to session hijacking, CSRF attacks, and cross-site tracking. This tool scans all Set-Cookie headers and grades each cookie individually.
