Free Web Security Tool

Review whether a website is sending the headers that help reduce browser-based security risk.

Enter a public website URL to inspect HTTPS and a focused set of security headers. This tool does not scan for vulnerabilities or attempt exploitation. It only reviews safe response metadata.

Run the Tool

What this checker looks for

Security headers help browsers enforce safer defaults, reduce content injection risk, limit framing abuse, and tighten how pages handle referrers, file types, and browser permissions.

Only public http/https URLs are allowed. Internal hosts, localhost, and private IPs are blocked.

Website Security Header Score

Run the tool to see your results.

When a result is ready, you’ll see your score or risk level, plain-English findings, and the next actions worth prioritizing.

How To Use This Result Safely

Helpful guidance, not a final security or legal conclusion.

This tool uses public records, safe response metadata, or the answers you provide. It does not perform intrusive testing or exploit scanning.

  • Use this result as educational guidance and a discussion starter, not as a penetration test, exploit scan, or final security verdict.
  • Do not treat the result as legal, compliance, insurance, or regulatory advice.
  • Important decisions should still be validated through a professional review of your real environment, vendors, and business requirements.

What this checker looks for

Security headers help browsers enforce safer defaults, reduce content injection risk, limit framing abuse, and tighten how pages handle referrers, file types, and browser permissions.

  • HTTPS availability and redirect behavior
  • Strict-Transport-Security (HSTS)
  • Content-Security-Policy (CSP)
  • X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy
  • Visible Server header exposure when present

Why these headers matter

Headers do not replace secure coding, patching, or secure hosting, but they are part of a mature baseline. They can reduce clickjacking exposure, make MIME confusion harder, improve browser trust boundaries, and show whether HTTPS is being enforced consistently.

Professional Review

Want a professional review of your results?

If your site is missing key headers or HTTPS controls, Red Shield IT can help review the web hosting stack, reverse proxy settings, and safer deployment standards.

What a consultation can help clarify

  • Whether the result reflects a configuration gap, an operational gap, or both
  • Which issues should be prioritized first for security or business impact
  • What a realistic remediation plan looks like for your environment

FAQ

Common questions about Website Security Header Checker.

Does this tool scan my website for exploits?

No. It only performs a lightweight request to inspect response headers and HTTPS behavior. It does not scan ports, test login pages, or attempt vulnerabilities.

Why is the Server header noted?

Some organizations prefer to avoid exposing unnecessary platform detail in the Server header. While not a major control on its own, reducing unnecessary disclosure is still a reasonable hygiene step.

What if my site has a CSP but it is permissive?

A CSP can exist and still need tuning. This checker focuses on whether the header is present. A deeper review is needed to judge whether the policy is appropriately restrictive for your site.
