Injection Guard is a WordPress plugin designed to block malicious query string attacks and suspicious URL parameters. It logs all incoming attempts, blocks harmful parameters, and adds extra security intelligence to your WordPress admin—like user session tracking and capability audit.
The plugin uses the ig_ prefix for database keys and functions, follows WordPress coding standards, and supports multiple languages. It’s compatible with pretty permalinks and helps in securing your site from automated bots and manual attacks.
