Content Security Policy Manager is a WordPress plugin that allows you to easily configure <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP" rel="nofollow ugc">Content Security Policy headers</a> for your site. You can have different CSP headers for the admin interface, the frontend for logged in users, and the frontend for regular visitors. The CSP directives can be individually enabled, and each policy can be set to enforce, report or be disabled.
Please note that this plugin offers limited help in figuring out what the contents of the policy should be. It only lets you configure the CSP in a easy to use interface.
