FAQs

 HTTP security headers are response headers sent by a web server that instruct browsers how to securely handle your website's content. They help protect against common web attacks and improve overall security. 
 Content Security Policy (CSP) is a security header that controls which resources can be loaded by your website, helping prevent Cross-Site Scripting (XSS) and content injection attacks. 
 Most modern websites should implement headers such as Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and X-Frame-Options where applicable. 
 Yes. Some headers—especially Content Security Policy (CSP)—can block legitimate resources if configured incorrectly. Always test your configuration before deploying it to production. 
 The generator creates secure HTTP response headers based on your selected options, making it easy to implement recommended browser security policies. 
 HTTP Strict Transport Security (HSTS) forces browsers to access your website only over HTTPS, reducing the risk of protocol downgrade and man-in-the-middle attacks. 
 Yes. The generated values can be used with Apache, Nginx, IIS, reverse proxies, or application frameworks such as Laravel, Express.js, Django, and ASP.NET.
