How the Security Headers Generator works

Generate secure HTTP response headers in four simple steps.

1

Configure Security Headers

Enable the HTTP response headers you need and customize policies such as Content Security Policy (CSP), HSTS, and Referrer Policy.

2

Preview & Validate

Review the generated security headers in real time and verify that the configuration follows current security best practices.

3

Copy or Download

Copy the generated headers or download the configuration for use with Apache, Nginx, or your application server.

How to Apply Your Security Headers

1 Select Your Web Server Target
Choose your server environment (Apache, Nginx, or Raw HTTP) using the platform selector above to generate the correct syntax format.
2 Copy the Generated Snippet
Click the Copy button in the output box to copy all configured security directives to your clipboard.
3 Locate Your Configuration File
Open your website's root directory using File Manager or SSH: For Apache: Open or create the .htaccess file in your root folder (e.g., public_html). For Nginx: Open your site's virtual host configuration file (usually located in /etc/nginx/sites-available/).
4 Paste and Save Changes
Paste the generated snippet into your configuration file, save the file, and restart or reload your web server if required (e.g., sudo systemctl reload nginx).
5 Test Your Site Configuration
Open your website in an incognito window and check the response headers using your browser’s developer tools (F12 > Network tab) or an online security header scanner to verify implementation.

FAQs

What are HTTP security headers?
 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. 
What is Content Security Policy (CSP)?
 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. 
Which security headers should I use?
 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. 
Can incorrect security headers break my website?
 Yes. Some headers—especially Content Security Policy (CSP)—can block legitimate resources if configured incorrectly. Always test your configuration before deploying it to production. 
What does the Security Headers Generator do?
 The generator creates secure HTTP response headers based on your selected options, making it easy to implement recommended browser security policies. 
What is HSTS?
 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. 
Will these headers work with Apache and Nginx?
 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. 
Is the Security Headers Generator free?
 Yes. The tool is completely free to use and requires no registration.
