DominoGuard is a focused, minimalistic security solution for WordPress. Designed to be fast and lightweight, it provides the essential security features every website needs with a clean configuration.
<h4>Key Features</h4>
<ul>
<li>Limit Login Attempts: Automatically block IPs for 15 minutes after 5 continuous failed login attempts, keeping brute-force attacks at bay.</li>
<li>Email Two-Factor Authentication (2FA): Add an extra layer of security for Administrators. When enabled, logging in requires a 6-digit code sent to the admin’s email address.</li>
<li>Brute Force Protection: Easily disable XML-RPC, a common vector for brute force and pingback attacks.</li>
<li>Block User Enumeration: Prevent attackers from discovering your administrator username by blocking <code>/?author=N</code> query scans.</li>
<li>Basic Firewall: A lightweight WAF that silently blocks simple directory traversal attempts (<code>../</code>) and basic malicious query strings commonly found in automated SQL injections.</li>
</ul>
<h4>Why DominoGuard?</h4>
Many security plugins suffer from excessive features that can impact performance. DominoGuard focuses on delivering efficient performance by utilizing standard WordPress functions, keeping your site secure with minimal resource usage.
