A security headers generator builds the HTTP response headers that harden your website, producing ready-to-paste configuration for headers like Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options. Instead of memorizing syntax or copying fragile snippets, you choose the protections you want and receive correctly formatted rules. This free security headers generator turns a fiddly, error-prone task into a quick step, giving you server-ready code that closes common gaps and strengthens your site's defenses.
What the security headers generator produces
This security headers generator outputs a complete set of hardening headers formatted for your stack. It creates Strict-Transport-Security to enforce HTTPS, a Content-Security-Policy that whitelists trusted script and asset sources, X-Frame-Options to block clickjacking, X-Content-Type-Options to prevent MIME sniffing, and Referrer-Policy and Permissions-Policy to limit data exposure. You get the rules as ready-to-paste configuration, typically for common servers and CDNs, so the values are correct and consistent. Instead of hand-writing directives and risking a typo that silently disables a protection, you receive a coherent header block designed to drop straight into your server or edge configuration.
How to deploy the generated headers
Paste the generated rules into the place that controls your responses: your web server config, your framework's middleware, or your CDN's header settings, so every request is covered rather than a handful of pages. Apply the straightforward headers first, then introduce Content-Security-Policy carefully, since a strict policy can block legitimate scripts or styles. Start it in report-only mode, watch for violations, and tighten from there. After deploying, run a headers checker to confirm each directive returns as intended. Keep the configuration in version control so the protection is documented and easy to update as your site evolves.
Best practices for security headers
Aim for the strongest policy your site can support without breaking functionality, then relax only where necessary. Avoid overly broad Content-Security-Policy values like unsafe-inline, which undercut the protection you set out to add. Prefer a preload-ready Strict-Transport-Security policy once you are confident every subdomain serves HTTPS. Review your headers whenever you add new third-party scripts, since each one may need a source added to your policy. Test in a staging environment before shipping, and recheck periodically as browsers evolve their recommendations. Treat header configuration as living security hygiene rather than a one-time setup you can forget in 2026.
Frequently Asked Questions
Which servers does the Security Headers Generator support?
It generates config blocks for Nginx, Apache, and Cloudflare. Each output uses the correct syntax for that platform, so you can paste it straight into your server config or dashboard without any translation.
Will the generated headers break my website?
The generator starts with safe, widely compatible defaults. Stricter policies like a tight Content-Security-Policy are marked clearly so you can test them first. Deploy on staging before production when you can.
Is the Security Headers Generator free?
Yes. It is free to use in 2026 after you create a Brainito account. Generate configs for as many sites and server setups as you need, and come back any time your stack changes.
