BotShield CAPTCHA for Contact Form 7 – Advanced Spam Protection with Turnstile, reCAPTCHA, Arithmetic, and Alphanumeric.

Aneesh MK

<p><strong>Cybernob Turnstile for Cloudflare</strong> integrates <a href="https://www.cloudflare.com/products/turnstile/" rel="nofollow ugc">Cloudflare Turnstile</a> into your WordPress site — the privacy-friendly CAPTCHA that stops bots silently, without making real users solve puzzles.</p>
<p>This plugin is an independent, third-party integration and is not affiliated with or endorsed by Cloudflare, Inc.</p>
<h4>Protected locations</h4>
<ul>
<li><strong>Login form</strong> — blocks brute-force and credential-stuffing attacks</li>
<li><strong>Registration form</strong> — prevents automated account creation</li>
<li><strong>Comment form</strong> — stops spam comments without Akismet</li>
<li><strong>Contact Form 7</strong> — automatically protects every CF7 form on your site</li>
</ul>
<h4>Features</h4>
<ul>
<li><strong>Live status checker</strong> — the settings page shows instantly whether your API keys are valid and reachable</li>
<li><strong>Invisible mode</strong> — widget stays hidden; the form auto-submits once the challenge passes silently</li>
<li><strong>Three themes</strong> — Auto (follows system preference), Light, Dark</li>
<li><strong>Two appearance modes</strong> — Always visible, or show on interaction only</li>
<li><strong>Clean uninstall</strong> — all plugin options are removed on deletion, including multisite support</li>
<li><strong>Translation ready</strong> — all strings wrapped in i18n functions with the correct text domain</li>
<li><strong>No bundled libraries</strong> — only Cloudflare’s own CDN script is used; nothing extra added to your site</li>
</ul>
<h4>Why Turnstile?</h4>
<p>Unlike reCAPTCHA, Cloudflare Turnstile does not track users across sites or require Google accounts. It is designed to be GDPR-friendly and invisible to legitimate users by default.</p>
<h4>Getting started</h4>
<ol>
<li>Create a free <a href="https://dash.cloudflare.com/?to=/:account/turnstile" rel="nofollow ugc">Cloudflare Turnstile</a> site widget</li>
<li>Copy your <strong>Site Key</strong> and <strong>Secret Key</strong></li>
<li>Paste them into <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Cybernob Turnstile</strong> and save</li>
<li>The live status indicator confirms everything is working</li>
</ol>
<h3>External Services</h3>
<p>This plugin connects to Cloudflare’s Turnstile service to display CAPTCHA challenges and verify user responses.</p>
<ul>
<li><strong>Service:</strong> Cloudflare Turnstile</li>
<li><strong>When used:</strong> When a protected form is loaded (widget script) or submitted (token verification). Only active after the administrator has entered API keys in the plugin settings.</li>
<li><strong>Data sent:</strong> On verification — the Turnstile response token and the visitor’s IP address are sent to Cloudflare’s API endpoint.</li>
<li><strong>Endpoint:</strong> https://challenges.cloudflare.com/turnstile/v0/siteverify</li>
</ul>
