<p><strong>Sitevorx</strong> is a lightweight, all-in-one WordPress plugin that helps you optimize performance, harden security, and manage your website from a single, modern dashboard. No bloat, no external dependencies — just the tools you need.</p>
<h4>Security Center (NEW in 1.1.0)</h4>
<ul>
<li><strong>Security Score Dashboard</strong>: A single 0–100 score that summarizes the hardening state of your site, with prioritized recommendations.</li>
<li><strong>Core Integrity Checker</strong>: Compares every WordPress core file against the official <code>api.wordpress.org</code> MD5 checksums to detect modified, missing, or extra files.</li>
<li><strong>HTTP Security Headers</strong>: One-click enable <code>X-Content-Type-Options</code>, <code>X-Frame-Options</code>, <code>Referrer-Policy</code>, and <code>Permissions-Policy</code> on the frontend.</li>
<li><strong>Login Honeypot</strong>: Invisible bait field on <code>wp-login.php</code> that silently rejects spam bots without affecting real users.</li>
<li><strong>User Enumeration Protection</strong>: Blocks <code>?author=N</code> probing and the public REST <code>/wp/v2/users</code> endpoint for non-logged-in visitors.</li>
<li><strong>Login Notification</strong>: Emails the administrator whenever an account with <code>manage_options</code> logs in successfully (1-hour cooldown per IP).</li>
<li><strong>Login Attempt Limiter</strong>: Lock out IPs after repeated failed login attempts, with configurable threshold, lockout duration, and IP allowlist.</li>
<li><strong>Secret Login URL</strong>: Hide the default <code>wp-login.php</code> behind a custom keyword.</li>
<li><strong>Google reCAPTCHA v2 / v3</strong>: Protect the login form from bots, with a configurable v3 score threshold.</li>
<li><strong>Disable XML-RPC</strong> and <strong>Disable File Editor</strong>: Block DDoS / brute-force vectors and stop code editing from the dashboard.</li>
</ul>

<li><strong>Heartbeat Throttle</strong>: Slows the Heartbeat API to 60 seconds instead of disabling it, preserving autosave and post-locking.</li>

<h3>External Services</h3>
<h4>Google reCAPTCHA (v2 and v3)</h4>
<p>Sitevorx can optionally integrate with Google reCAPTCHA (v2 checkbox or v3 invisible / score-based) to protect the WordPress login form. This feature is disabled by default and only works when an administrator explicitly enables it, selects a version, and provides valid Google-issued API keys.</p>
<p>When enabled, the plugin loads the Google reCAPTCHA JavaScript on the login screen and sends the generated verification token to Google’s verification endpoint (<code>https://www.google.com/recaptcha/api/siteverify</code>) during login validation. For v3, the configurable score threshold (filter <code>sitevorx_recaptcha_v3_score_threshold</code>, default <code>0.5</code>) is compared against Google’s returned score.</p>
<p>This service is provided by Google:<br />
* Service URL: https://www.google.com/recaptcha/<br />
* Verification endpoint: https://www.google.com/recaptcha/api/siteverify<br />
* Terms of Service: https://policies.google.com/terms<br />

<h4>WordPress.org Core Checksums API</h4>
<p>The <strong>Security Center <span aria-hidden="true" class="wp-exclude-emoji">→</span> Kiểm Tra Toàn Diện <span aria-hidden="true" class="wp-exclude-emoji">→</span> WordPress Core Integrity</strong> check (off by default; runs only when the admin clicks “Kiểm tra”) fetches the official MD5 checksums for the installed WordPress version from WordPress.org so it can flag modified or missing core files.</p>
<ul>
<li>Verification endpoint: https://api.wordpress.org/core/checksums/1.0/</li>
<li>Request payload: only the installed WordPress version string (e.g. <code>6.4.2</code>) and the locale <code>en_US</code>. No site URL, user data, or content is sent.</li>
<li>Operated by: WordPress.org</li>
<li>Terms of Service: https://wordpress.org/about/privacy/</li>
</ul>
