HTTP Security Headers Analyzer
This HTTP Security Headers Analyzer checks your website’s browser security headers including CSP, HSTS, X-Frame-Options, and more to evaluate overall web protection strength.
About This Tool
The HTTP Security Headers Analyzer helps you evaluate important browser security headers configured on your website. These headers protect users against common web-based attacks such as cross-site scripting (XSS), clickjacking, and data injection.
Modern websites rely on properly configured HTTP response headers to enforce browser-level security policies. Missing or weak headers can expose visitors to unnecessary risks and reduce overall site trust.
This tool analyzes your domain for:
- Strict-Transport-Security (HSTS)
- Content-Security-Policy (CSP)
- X-Frame-Options
- X-Content-Type-Options
- Referrer-Policy
- Permissions-Policy
- Server and X-Powered-By exposure
Based on detected headers, the tool calculates a security score and assigns a protection grade. The analysis is performed instantly and no data is stored or logged.
🛡️ FAQ – HTTP Security Headers Analyzer
What are HTTP security headers?
HTTP security headers are response headers sent by a web server to protect users from common web attacks like XSS, clickjacking, and MIME sniffing.
Examples include:
–Strict-Transport-Security (HSTS)
–Content-Security-Policy (CSP)
–X-Frame-Options
–Referrer-Policy
How does the Security Score work?
The score is calculated out of 100 based on the presence of important security headers and the absence of sensitive fingerprinting headers like Server and X-Powered-By.
Each header has a weighted impact on the final score.
Why does a major website sometimes show a low score?
Large websites may return different headers depending on request type, location, CDN behavior, or bot detection rules. The tool analyzes headers returned to the scanner at the time of request.
Does this tool check header quality or only presence?
The current version checks for the presence of important security headers. It does not deeply validate configuration strength (such as max-age length in HSTS).
Are any website headers stored?
No. The tool performs a live request and does not store or log any analyzed data.
