No, WP Ghost is designed to be lightweight and optimized for performance. It focuses on enhancing your site’s security without adding significant overhead. The plugin primarily works by hiding vulnerabilities in your WordPress core, themes, and plugins, which doesn’t require heavy resource usage or continuous monitoring.
Because WP Ghost doesn’t rely on real-time scanning or complex firewall rules like some other security plugins, its impact on site speed is minimal. It runs efficiently in the background, ensuring your site remains fast while benefiting from enhanced security.
In short, WP Ghost will not slow down your WordPress site and should actually help improve its overall security without compromising performance.
