Directive Analysis
Missing Directives
Security Headers
Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.
How to add it:
add_header Cross-Origin-Opener-Policy "same-origin" always;Header always set Cross-Origin-Opener-Policy "same-origin"Rules > Transform Rules > HTTP Response Header Modification > Set Cross-Origin-Opener-Policy to "same-origin"geolocation=(), sync-xhr=self, fullscreen=self
Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.
strict-origin-when-cross-origin
Controls how much referrer information is sent with requests, preventing data leaks to third parties.
max-age=31536000; includeSubDomains; preload
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.
1; mode=block
Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.
1 recommended security header is missing on network-dev01.regdev.uk.

Recommendations
- →Add form-action directive with appropriate restrictions
- →Consider implementing a stricter Content Security Policy
