Wordfence is a commonly used plugin for site security that has a free version and a premium version. Wordfence includes a number of constants that can be added to the site’s wp-config.php file to turn off specific features and change some of the defaults.
MainWP has an easy-to-use code snippets plugin that will allow you to save these constants to any of the connected child sites into the child sites wp-config.php file.
The Wordfence scan results page will show up to 100 results by default this can be increased or decreased by using the following constant and setting the value as lower or higher.
define('WORDFENCE_SCAN_ISSUES_PER_PAGE', 50);

define('WORDFENCE_SCAN_FAILURE_THRESHOLD', 600);
