What are Security Headers?
Security headers are HTTP response headers that tell browsers how to behave when handling your site's content. They protect against:
- Cross-Site Scripting (XSS): Malicious scripts injected into your site
- Clickjacking: Invisible iframes that trick users into clicking malicious content
- Man-in-the-Middle: Attackers intercepting traffic between users and your site
- Data Injection: Malicious code or content inserted into your pages
Pro Tip: Most security headers can be added with just a few lines of configuration in your web server or CDN. Our tool provides copy-paste code for popular platforms!
