This tool allows you to quickly check the HTTP headers of any website. By entering a URL, the tool will fetch the website’s HTTP headers and display them, including key security-related headers. This can help you identify if your site is configured with essential security headers to protect it against common vulnerabilities.
What Are Security Headers and Why Should They Be Used?
Security headers are specific HTTP headers that help protect your website from various types of attacks and security risks. They are sent along with the response when a web server delivers a page to a user’s browser. Here are a few key security headers and their importance:
- X-Frame-Options: Prevents your site from being embedded in an iframe, protecting against clickjacking attacks.
- Content-Security-Policy (CSP): Helps prevent XSS attacks by specifying which dynamic resources are allowed to load on your page.
- Strict-Transport-Security (HSTS): Forces browsers to use HTTPS instead of HTTP, enhancing security by encrypting the connection.
- X-Content-Type-Options: Prevents browsers from interpreting files as something else (like scripts) to avoid certain types of attacks.
- Referrer-Policy: Controls the amount of referrer information sent when navigating between websites, reducing exposure of sensitive data.
- Permissions-Policy: Restricts the use of features (like geolocation or camera access) to prevent malicious use.
Using these headers enhances your site’s security by mitigating threats like data breaches, clickjacking, cross-site scripting (XSS), and more. They are essential for improving your site’s trustworthiness and protecting your users’ data.
