This standalone Free version functions fully on its own to hide the system generator and customize authentication errors to shield the dashboard from brute- force scanners. Please note: any advanced infrastructure hardening or extended backend modifications are part of a separate custom development track provided exclusively by the Rapid2004 Laboratory. Changelog #### 1.0 * Initial release of the basic security framework. =3.2 * Code optimization, syntax fix, and stable deployment. * 3 free tests for introductory acquaintance. ## Screenshots [⌊screenshot-1.png – Core hardening in action.

Activate the plugin through the ‘Plugins’ menu in the WordPress dashboard. ## FAQ ### Q1: There are many security plugins available. Why choose this one? A1: Agreed, the market is saturated. However, unlike heavy plugins that weigh as much as an iron bridge, mine does not assault the database with hundreds of queries, does not probe the PHP version just in case, and does not spy on your admin movements. It simply loads and executes. ### Q2: I am inexperienced. Can I install this plugin independently? A2: Absolutely. A core design goal for both free and pro versions was simplicity. You simply download, activate, and enjoy peace of mind. You rest while the plugin secures the architecture. ### Q3: Are there any installation limits, expiration dates, or plugin dependencies? A3: The Free version of Rapid2004 SH has no artificial limits. You can deploy it on a personal site, a corporate network, or an e-commerce platform. There is only one fundamental requirement: your project must run on WordPress, which you likely already know if you are reading this. ### Q4: Why is my admin interface displaying the author’s signature and domain? A4: The interface proudly displays the official signature of Volodymyr Novosolov alongside the main domain rapid2004.biz.ua. If you trust my expertise enough to secure your core infrastructure with this plugin, perhaps you should skip searching public developer forums for unreliable help to extend your site’s functionality. For dedicated architecture expansions and custom standalone modifications, contact the author directly through the secure gateway. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Rapid2004 security fixes — Core hardening” is open source software.
