Safe Headers Scanner helps WordPress administrators identify common issues that may cause header-related problems. 
The plugin scans installed themes and plugins for: 
* Unnecessary whitespace before <code><?php</code> tags 
* Extra whitespace after closing <code>?></code> tags 
* Direct output (e.g., <code>echo</code>, <code>print</code>) before headers are sent
Results are displayed in a clear report, so you can review and fix potential issues easily.

This plugin does not make any changes to your server configuration, such as the .htaccess file, but instead sends the headers as part of the WordPress page response. The reason for this is that many of them are not valid for assets such as stylesheets and images, but are sent anyway if the server configuration method is used.
Unlike many security plugins, these headers are also sent for your admin panel, where security is arguably the most important.
Headers that can be set include… 
* Feature-Policy 
* Referrer-Policy 
* Strict-Transport-Security 
* X-Frame-Options 
* X-Content-Type-Options 
* X-XSS-Protection 
* X-Permitted-Cross-Domain-Policies 
* Expect-CT
