In the digital age, real-time communication has become a cornerstone of customer engagement. Joinchat is a powerful WordPress plugin designed to connect website visitors with businesses instantly through their favorite chat platforms, such as WhatsApp, Messenger, and Telegram. By offering a fully customizable floating contact button, dynamic CTAs, and deep integrations with e-commerce and analytics tools, Joinchat transforms customer support into a seamless, interactive experience.
While its functionality is impressive, security remains a critical factor when embedding third-party scripts and handling visitor interactions. A vulnerable chat plugin could become a direct entry point for attackers—risking data leakage, phishing, and even complete site compromise. Recognizing this, Joinchat version 6.0.6 underwent an extensive Plugin Security Certification process by CleanTalk and has successfully earned PSC-2025-64584.
This certification verifies that Joinchat meets high standards of secure coding practices, has been rigorously tested against real-world attack vectors, and ensures that the integrity of your site and data is preserved.
