Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.
Controls how much referrer information is sent with requests, preventing data leaks to third parties.
How to add it:
add_header Referrer-Policy "strict-origin-when-cross-origin" always;Header always set Referrer-Policy "strict-origin-when-cross-origin"Rules > Transform Rules > HTTP Response Header Modification > Set Referrer-Policy to "strict-origin-when-cross-origin"max-age=31536000; preload; includeSubDomains
Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.
nosniff
Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.
DENY
Prevents the page from being embedded in iframes, protecting against clickjacking attacks.
0
Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.

Beyond headers: infrastructure exposure
via OSN, our sister projectSecurity headers protect the browser. OSN maps what's exposed underneath — servers, open ports, known CVEs, DNS and WHOIS.
