If you have our WordPress plugin installed, we will automatically try to inject the security headers into the response. If this does not work, you may have to add the .htaccess rules below manually to your .htaccess file.

If you do not have a WordPress site or do not want to use our plugin, you can manually add the following security headers into the .htaccess file if you use Apache:
<IfModule mod_headers.c>
   Header set Referrer-Policy "strict-origin-when-cross-origin"
   Header set X-XSS-Protection "1; mode=block"
   Header set X-Content-Type-Options "nosniff"
   Header set X-Frame-Options "SAMEORIGIN"
   Header set Strict-Transport-Security "max-age=31536000"
   Header unset X-Powered-By

If you are running nginx, add the following to the configuration file and restart or reload nginx:
add_header X-Frame-Options SAMEORIGIN;
add_header X-Content-Type-Options nosniff;  
add_header X-XSS-Protection "1; mode=block";  
add_header Strict-Transport-Security "max-age=31536000";
add_header Referrer-Policy "strict-origin-when-cross-origin";

Additionally, in order to permanently remove the X-Powered-By header instead of using above changes, set the expose_php value of your PHP configuration to "Off". You may have to ask your host to make above changes.

Note that it may take up to 12 hours before the security headers error in the portal is resolved. Or click on the "Rescan Site" button when you view your site in our portal.
