By default the plugin will keep 5,000 Security Alerts in the WordPress audit trial. When such limit is reached, older alerts are automatically deleted by the plugin to make place for the new ones. You can configure automatic pruning of security alerts from the plugin’s settings page. As seen in the below screenshot you can either configure the maximum number of security alerts the WordPress audit trial should have, or configure the plugin to automatically delete security alerts which are older than a specific time. To specify a time limit enter the value in numbers and words, for example 3 months.
