Scope
Inventory routes, embeds, scripts, redirects, and hosting layers.
Set CSP, HSTS, framing, referrer, permissions, and MIME headers with route coverage and rollout evidence.
Page intent
resourceA guide for setting browser security headers based on application behavior, not copy-pasted header blocks.
Inventory routes, embeds, scripts, redirects, and hosting layers.
Define target headers by page sensitivity and browser behavior.
Roll out report-only or staged enforcement where needed.
Retest coverage and record accepted exceptions.
The value of a guide is not the document itself; it is the scan scope, fix ownership, retest criteria, and evidence it helps the team produce.
A guide for setting browser security headers based on application behavior, not copy-pasted header blocks.
Review CSP, HSTS, X-Frame-Options or frame-ancestors, Referrer-Policy, Permissions-Policy, and MIME protections.
Validate header coverage across app routes, APIs, static assets, previews, and redirects.

CSP policies that look strict but allow unsafe script sources.
Frame, referrer, or permissions policies missing on sensitive pages.

Breaking production behavior because reporting and rollout were skipped.
Start with the headers that match your biggest browser risks: framing, transport security, referrer leakage, permissions, and script control.
Not immediately. Many apps need report-only rollout and explicit handling for third-party scripts.
Some browser headers apply mainly to pages, but coverage should still be reviewed across APIs, redirects, assets, and previews.
SafeVibe reviews header presence, route coverage, risky exceptions, rollout status, and retest evidence.
Use Security headers guide as the starting point, then turn the checklist into SafeVibe scan scope and remediation evidence.
