Analyze HTTP security headers like HSTS, CSP, X-Frame-Options.
What is Security Headers Check?
HTTP security headers are your first line of defense against common web attacks. They instruct browsers on how to handle your content, preventing cross-site scripting (XSS), clickjacking, MIME-type sniffing, and other attacks. Major security standards like OWASP recommend implementing these headers on all web applications.

Frequently asked questions
What security headers should every website have?
At minimum, every website should implement: Strict-Transport-Security (HSTS) to enforce HTTPS, Content-Security-Policy (CSP) to prevent XSS attacks, X-Frame-Options to prevent clickjacking, X-Content-Type-Options to prevent MIME sniffing, and Referrer-Policy to control information leakage.
How do I add security headers to my website?
Security headers are added through your web server configuration. In Apache, use the Header directive in .htaccess. In Nginx, use add_header in your server block. In Caddy, use the header directive. Many CDN providers like Cloudflare also allow you to set security headers through their dashboard.
Do security headers affect SEO?
Not directly, but they contribute to site security which Google considers a ranking factor. HTTPS (enforced by HSTS) is a confirmed ranking signal. Additionally, security incidents caused by missing headers can lead to your site being flagged as unsafe, which severely impacts rankings.
