Why do security headers matter?
Headers like Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy reduce common browser-side attack paths and launch regressions.
What is in the launch pack?
The pack includes generated server config, a summary of reviewed header names and issue categories, a release checklist, and a starter verify-security-headers.mjs script for live production checks. Raw pasted header values are not copied into the pack.
Should I enforce a new CSP immediately?
Use Content-Security-Policy-Report-Only first when a site has third-party scripts, inline legacy code, or account/checkout flows. Enforce only after reviewing reports and testing key routes.
