With increasing cyber threats in 2025, web developers and business owners must prioritize cybersecurity. A secure website doesn’t just protect your users—it also improves your credibility and SEO ranking. One of the most overlooked yet powerful strategies is properly configuring HTTP security headers. A trusted tool to evaluate and implement them is SecurityHeaders.com.
In this post, we’ll explore what security headers are, how they work, and how you can use SecurityHeaders.com to audit and improve your site’s protection in just a few steps.
Security headers are HTTP response headers that tell browsers how to behave when interacting with your site. They add an extra layer of protection by preventing vulnerabilities such as:
Even with an SSL certificate and secure login system, missing security headers can leave your site exposed.
SecurityHeaders.com, built by Scott Helme, is a free online service that scans your website and provides a detailed report on which HTTP security headers are implemented, and which are missing or misconfigured.

You’ll get actionable suggestions like:
Add Content-Security-Policy
Implement Strict-Transport-Security
Use X-Content-Type-Options: nosniff
Include Referrer-Policy
and Permissions-Policy
Header | Purpose |
---|---|
Content-Security-Policy | Prevents XSS by specifying allowed content sources |
Strict-Transport-Security | Forces HTTPS and protects against downgrade attacks |
X-Frame-Options | Prevents clickjacking by disallowing iframe embedding |
X-Content-Type-Options | Stops MIME type sniffing |
Referrer-Policy | Controls how much referrer info is shared |
Permissions-Policy | Controls access to APIs like camera, geolocation, etc. |
You can implement headers in your web server or application:
Apache (via .htaccess):
Header set X-Content-Type-Options "nosniff"
Header set X-Frame-Options "DENY"
Header set Strict-Transport-Security "max-age=31536000; includeSubDomains"
Nginx:
add_header X-Frame-Options "DENY";
add_header X-Content-Type-Options "nosniff";
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains";
Laravel (via middleware):
Use packages like spatie/laravel-security-headers
Google and other search engines consider HTTPS and page safety as part of their ranking algorithms. Sites with weak security headers might not only be vulnerable but also rank lower in search results. By using SecurityHeaders.com and implementing the right headers, you’re protecting your users and improving your visibility.
