Security Headers Generator – Generate Secure HTTP Headers Online
HTTP security headers are an important part of modern website security. They help browsers understand how your website should handle HTTPS connections, embedded content, browser features, MIME types, referrer information, and potentially dangerous scripts.
Our free Security Headers Generator helps you create commonly used HTTP security headers for your website. Select the security policies you need, configure their values, and generate production-ready header configurations that you can add to your web server or application.
What Are HTTP Security Headers?
HTTP security headers are response headers sent by a web server to provide browsers with security-related instructions. They can help reduce risks such as clickjacking, MIME-type sniffing, insecure connections, unwanted browser capabilities, and certain types of content injection attacks.
Security headers work as an additional security layer for websites and web applications. They do not replace secure application development, authentication, input validation, access control, server hardening, or regular security testing.
Strict-Transport-Security
HSTS tells compatible browsers that your website should only be accessed using HTTPS. It can help protect users from certain downgrade and insecure HTTP connection scenarios.
Example:
max-age=31536000
Content-Security-Policy
Content-Security-Policy controls which resources browsers are allowed to load. A carefully configured CSP can help reduce certain cross-site scripting and content injection risks.
Example:
default-src 'self'
X-Frame-Options
X-Frame-Options controls whether a page can be displayed inside a frame. It is commonly used to help protect websites against clickjacking.
Common value:
SAMEORIGIN
X-Content-Type-Options
This header helps prevent browsers from MIME-sniffing resources and interpreting content as a different type from the one declared by the server.
Recommended value:
nosniff
Referrer-Policy
Referrer-Policy controls how much referrer information browsers send when users navigate from one page or website to another.
Example:
strict-origin-when-cross-origin
Permissions-Policy
Permissions-Policy allows websites to control access to browser features such as camera, microphone, geolocation, and other browser capabilities.
Example:
camera=(), microphone=()
How Does the Security Headers Generator Work?
The Security Headers Generator lets you configure commonly used security policies and creates header configuration based on the options you select. The generated output can then be reviewed and added to your website's server or application configuration.
- Select the security headers you want to configure.
- Choose or customize the available header values.
- Review the generated security header configuration.
- Copy the generated configuration for your website.
- Add the headers to your web server or application configuration.
- Test your website carefully after applying the generated policies.
What Can You Generate?
Depending on the options available in the generator, you can create configurations for commonly used HTTP security headers including HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy.
The generated configuration is intended to provide a practical starting point for improving your website's security headers. Always review the generated values against your website's actual scripts, APIs, embedded content, third-party services, and browser requirements before deploying them.
A generated configuration is not a guarantee of complete website security and should be tested before being used on a production site.
Why Generate Security Headers?
- Create commonly used security headers quickly.
- Reduce manual configuration work.
- Establish safer browser security policies.
- Help protect against certain browser-based attacks.
- Control browser features and permissions.
- Generate reusable server configuration.
Who Should Use This Tool?
The Security Headers Generator can be useful for website owners, developers, SEO professionals, system administrators, agencies, and businesses that want to improve their website's HTTP security configuration.
- Website developers
- WordPress administrators
- PHP and CodeIgniter developers
- SEO professionals
- Web agencies
- Small business website owners
- Server administrators
Important Security Note
Security headers should be configured according to the actual requirements of your website. In particular, a strict Content-Security-Policy or Permissions-Policy can affect scripts, styles, APIs, advertisements, fonts, frames, browser features, and other third-party resources. Review and test generated headers carefully before applying them to a production website.
Frequently Asked Questions
Q: What is a Security Headers Generator?
A: It is an online tool that helps generate commonly used HTTP security headers and their configuration values for websites and web applications.
Q: Is this Security Headers Generator free?
A: Yes. You can use the Security Headers Generator online to create security header configurations without manually writing every header from scratch.
Q: Which security headers can be generated?
A: Common headers include Strict-Transport-Security, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy.
Q: Can I use the generated headers on a production website?
A: Yes, but you should review and test the generated configuration before deploying it. Some policies can affect website resources, scripts, APIs, advertisements, embedded content, and browser functionality.
Q: Does generating security headers make my website completely secure?
A: No. Security headers provide an additional layer of protection, but they do not replace secure coding, authentication, access controls, input validation, HTTPS configuration, server security, vulnerability testing, or other security practices.
Q: Can Content-Security-Policy break my website?
A: Yes. An incorrectly configured CSP can block legitimate JavaScript, CSS, images, fonts, APIs, advertisements, analytics, frames, or other external resources. Always test CSP changes carefully before applying strict policies to a production website.
