The HTTP Headers plugin is configuration-heavy by design. Each header (Content-Security-Policy, Strict-Transport-Security, Referrer-Policy, Permissions-Policy, X-Frame-Options, X-Content-Type-Options, and dozens more) lives as a WordPress option with a value and an output method (Apache .htaccess, PHP, or .user.ini). The admin shows one tab per header. The total posture of the site (how many headers are enforced, how many are still default, which output method dominates) never appears as a chart.

SleekView Charts connects to the WordPress database and reads the http_headers option keys directly. Each header has its own enabled flag, value, and method, so a Number card counts active headers, a Pie splits them by output method, and a Bar lists which CSP directives carry custom values. The plugin supports more than 35 headers in total, with full CSP directive coverage including script-src-elem, script-src-attr, style-src-elem, style-src-attr, navigate-to, and the modern Permissions-Policy directives.

The Cookie Security side of the plugin (SameSite, Secure, HttpOnly) writes into the same option family, so a card can track cookie posture alongside response-header posture. Custom headers added through the plugin live in a dedicated option array and appear as their own Bar group. CORS headers (Access-Control-Allow-Origin and friends) carry origin lists rather than single values, so the dashboard can count allowed origins per site and surface unusually long lists. None of this needs a header reflection service: the option keys themselves describe the policy.

Security headers are an unusually shaped problem. Each one has its own value, its own browser semantics, and its own deployment method. The HTTP Headers plugin supports more than 35 of them, with CSP directives alone covering more than a dozen options.

The default admin gives each header a tab, which is the right shape when editing one. It is the wrong shape when reviewing the whole posture. A Number card of active headers, a Pie of output methods, and a Bar of CSP directives compress the same option keys into a one-glance answer.

The data already exists in the http_headers option family with the structure the plugin maintains. Visualising it as cards costs nothing on the writing side and lets the security team open a posture dashboard the same way they open an uptime monitor.
