Breach Radar is a free and open-source security plugin designed for WordPress sites, providing automated protection against data breaches involving user email addresses. The tool is aimed at WordPress site administrators who want to proactively monitor their user base for exposure in large-scale data leaks, helping them respond before user accounts are compromised.
The plugin operates by scanning the site's user database and cross-referencing the stored email addresses against a breach database containing over 647 million records. This process is fully automated: after installation and entry of a site-specific API key, Breach Radar performs daily scans using the WordPress cron system. If any user email is found in a known breach, the plugin sends immediate notifications to the site administrator. Admins can configure the notification threshold to receive alerts only when a certain number of breaches are detected. Additionally, the plugin's control panel provides statistics for the past seven days and allows administrators to manually trigger scans as needed.
Breach Radar includes several features to help manage and document security incidents. It maintains filterable scan logs, supports customizable admin notifications, and offers a [breach_radar_badge] shortcode for displaying a protection badge on the site. The scanning process is privacy-conscious: user email addresses are never stored by the API, and only the results and numerical statistics are returned from each query. The plugin supports four languages—Turkish, English, Russian, and Azerbaijani—to accommodate a diverse user base.
Installation is straightforward, requiring the administrator to obtain a unique API key for each site by submitting the site's URL and admin email. The plugin can be installed directly from the WordPress plugin directory or downloaded from GitHub. There are no paid plans or credit card requirements, and all features are available without cost. Breach Radar is positioned as a dedicated WordPress security solution for monitoring and responding to data breaches affecting user credentials.
In the Security & compliance platforms space, Breach Radar takes a focused approach. It focuses on protecting WordPress site users from compromised credentials by detecting data breaches involving their emails. It is built as an open-source project for wordPress site owners. Breach Radar is open source under the GPL-2.0 license. It runs on the web.
Breach Radar first shipped in 2025. PulseGate's similarity index finds few close equivalents — Breach Radar occupies a relatively distinct niche. Key capabilities include email breach scan, instant alerts, and wordPress integration. The interface is available in 5 languages, including Azerbaijani, German, and English.
