Security Headers

✓Permissions-PolicyPresent

autoplay=(*), camera=(), fullscreen=(*), geolocation=(), gyroscope=(*), microphone=(), payment=(), picture-in-picture=(*)

Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.

✓Referrer-PolicyPresent

strict-origin-when-cross-origin

Controls how much referrer information is sent with requests, preventing data leaks to third parties.

✓Strict-Transport-SecurityPresent

max-age=31536000; includeSubDomains; preload

Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.

✓X-Content-Type-OptionsPresent

nosniff

Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.

✓X-Frame-OptionsPresent

DENY

Prevents the page from being embedded in iframes, protecting against clickjacking attacks.

✗X-XSS-ProtectionMissing

Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.

How to add it:

nginx

add_header X-XSS-Protection "0" always;

apache

Header always set X-XSS-Protection "0"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set X-XSS-Protection to "0"

Beyond headers: infrastructure exposure

via OSN, our sister project

Security headers protect the browser. OSN maps what's exposed underneath — servers, open ports, known CVEs, DNS and WHOIS.
