GD Security Headers for WordPress

Configure various security-related HTTP headers, including Content Security Policy, Feature Policy, Referrer Policy and more. For CSP and XSS plugin supports report logging with 2 additional database tables to store reports from browsers.

Supported security headers The plugin has support for the following HTTP headers:

Content Security Policy (CSP) – with reporting

XSS Protection (XXP) – with reporting

Feature Policy (Permissions Policy)

Content Type – No Sniff Policy

Strict Transport Security

Referrer Policy

Frame Options

For CSP, the plugin allows you to set rules for all currently supported directives, additional settings including setting the policy in Report or Live mode. The plugin also includes special extensions that can automatically fill CSP rules for popular Google services you might be using on your website (Fonts, Maps, Adsense, Analytics, TagManager and more) and other popular services (Gravatar, Instagram, PayPal Vimeo and more).

And, for Feature Policy (or Permissions Policy), the plugin allows you to set rules for all currently supported rules (over 25 rules, supported by different browsers).

FLoC / Browsing Topics Permissions Policy rules list includes ‘browsing-topics’ rule that can be used to disable Google’s new tracking method ‘Browsing Topics API’ (which replaced ‘Federated Learning of Cohorts’ or ‘FLoC’).

Methods for adding headers The plugin can add all the generated headers into HTACCESS file (for Apache web servers), and they will be applied to all files, not just WordPress generated content. If your website is not using Apache (or .HTACCESS), all rules are generated with each page request and will work with any server type.
