Guard Dog

Guard Dog is a WordPress plugin designed to enhance login and account security for WordPress sites. It addresses common vulnerabilities at the login interface, focusing on practical measures to reduce unauthorized access and disruptive automated attacks. The plugin is positioned for site owners and administrators who want to strengthen security without relying on a centralized platform, as it operates directly within the user's WordPress installation.

Key features include the ability to set custom login URLs, implement two-factor authentication (2FA) via app or email, and support for passkeys. Guard Dog also integrates CAPTCHA providers to help block automated login attempts and offers login attempt limiting to further deter brute-force attacks. Additional protections include user enumeration prevention and password policy enforcement, as well as email verification options for added account validation.

For access control and monitoring, Guard Dog provides IP and username-based access rules, session management tools, and an activity log that records relevant events. The plugin supports temporary user access and is equipped to handle reverse proxy IP scenarios. These capabilities allow administrators to oversee active sessions, review account activity, and manage who can access the site in a granular manner.

Guard Dog is delivered as a plugin that is installed directly into a WordPress site, with no central platform required for its core functionality. 1 or higher. The tool emphasizes a plugin-first, site-controlled approach to security, focusing on login, authentication, sessions, and access workflows specific to WordPress environments. The product also features a mascot, Nina, reflecting a lighthearted brand identity, but the core focus remains on robust site-owned security controls.
