Security Guard
pluginsprout.com
A WordPress plugin from PluginSprout that runs a read-only scan of plugin, theme and must-use code, the uploads folder (including PHP hidden in images), the database, administrator accounts and core files, looking for ClickFix and EtherHiding scripts, web shells and obfuscated loaders. It can take known injected scripts out of pages and limit where page scripts connect with a Content-Security-Policy, starting in report-only mode. It sends no site files anywhere and never deletes or edits a file it flags. Licences cover 1, 5 or unlimited sites, each with a year of updates and email support.
