Security Headers

✗Permissions-PolicyMissing

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

How to add it:

nginx
add_header Permissions-Policy "camera=(), microphone=(), geolocation=()" always;
apache
Header always set Permissions-Policy "camera=(), microphone=(), geolocation=()"
cloudflare
Rules > Transform Rules > HTTP Response Header Modification > Set Permissions-Policy value
✓Referrer-PolicyPresent

same-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-OptionsMissing

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

How to add it:

nginx
add_header X-Content-Type-Options "nosniff" always;
apache
Header always set X-Content-Type-Options "nosniff"
cloudflare
Rules > Transform Rules > Managed Transforms > Enable "Add X-Content-Type-Options header"
✗X-Frame-OptionsMissing

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

How to add it:

nginx
add_header X-Frame-Options "DENY" always;
apache
Header always set X-Frame-Options "DENY"
cloudflare
Rules > Transform Rules > HTTP Response Header Modification > Set X-Frame-Options to "DENY"
✗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.
