GuardBee Security Check

GuardBee Security Check instantly checks the core HTTP security headers of any website you visit and shows a security grade (A–F) on the browser toolbar. What it checks • HTTPS usage • Strict-Transport-Security (HSTS) • Content-Security-Policy (CSP) • X-Frame-Options / frame-ancestors • X-Content-Type-Options • Referrer-Policy • Permissions-Policy • Cookie Secure / SameSite flags How it works All checks run entirely in your browser — no data is ever sent to a server. The extension reads the HTTP response headers of the pages you visit, computes a score from them, and keeps the result only for your current browser session (per tab).
