What Is a Security Headers Checker?

A Security Headers Checker helps you review HTTP response headers that protect a website. First, the tool fetches the URL headers. Next, it checks common protections such as HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. As a result, you can quickly see which protections are active and which ones are missing.

Moreover, security headers can reduce common browser-level risks. For example, some headers help prevent clickjacking, MIME sniffing, and unsafe referrer leakage. However, missing headers do not always mean a website is hacked. Therefore, the report should be used as a practical hardening checklist.

In addition, this tool is useful for WordPress sites, blogs, business websites, and developer audits. Then, after you add or adjust headers, you can test the page again. Consequently, you can improve your security setup step by step.

Content-Security-Policy Check

Review whether a CSP header exists. Furthermore, use it carefully because a strict CSP can block scripts if configured incorrectly.

HSTS Header Review

Check Strict-Transport-Security to confirm that browsers are told to use HTTPS. As a result, secure connections become more consistent.

Clickjacking Protection

Check X-Frame-Options and frame-related policies. Therefore, you can reduce the risk of your pages being embedded in unsafe frames.

Privacy and Browser Permissions

Review Referrer-Policy and Permissions-Policy. In addition, use them to limit information leakage and browser feature access.

How to Use the Security Headers Tool

First, enter the full URL you want to test. Then, click Check Security Headers. After that, review the score, passed headers, missing headers, warnings, and recommendations. Finally, copy or download the report if you need to save the audit.

Frequently Asked Questions

Is this Security Headers Checker free?

Yes. You can analyze website security headers and download reports for free.

Are missing security headers dangerous?

Missing headers are not always an emergency. However, adding the right headers can improve browser-level protection.

Is this the same as an HTTP Headers Checker?

No. An HTTP Headers Checker lists all response headers. Meanwhile, this tool focuses on security headers, scoring, and recommendations.

Can I add security headers in WordPress?

Yes. You can add them through your server, CDN, security plugin, or custom configuration. However, test changes carefully.
