Protocol Strict-Transport-Security enforces secure HTTPS connections, mitigating Man-In-The-Middle attacks. Essential for data integrity.
Content-Security-Policy restricts resource loading sources. Primary defense against Cross-Site Scripting injection vectors.
X-Frame-Options prevents clickjacking by denying iframe embedding. Ensures user interface cannot be redressed by malicious actors.
Scan any domain and instantly detect missing HTTP security headers like HSTS, CSP, X-Frame-Options, and more. Identify vulnerabilities before attackers do.
A simplified grading system (A-F) helps you understand the security posture of your website in seconds. Perfect for audits and client reporting.
Missing a header? We provide recommended values based on industry standards so you can patch weaknesses instantly.
Results are shown in a terminal-style log format with clear PASS/FAIL output. Easy to copy, screenshot, and share with your team.

YES. This scanner is completely free for public use. Advanced reporting and scheduled scans may be added in future versions.
NO. We do not permanently store scan targets. The scan runs in real-time and returns only the result output.
HTTPS alone is not enough. Headers like CSP, HSTS, and X-Frame-Options are required to protect against XSS, clickjacking, and downgrade attacks.
YES. This tool is designed for developers, agencies, and cybersecurity auditors. Screenshot-ready output makes reporting super easy.
Upgrade your website security. Prevent attacks before they happen. Strengthen your headers and keep your users protected.
