EchoFilter protects your WordPress forms from bots and spam using behavioral biometrics — analyzing mouse movement, typing patterns, and timing to distinguish real users from automated submissions.
How it works:
<ol>
<li>Install the plugin and enter your EchoFilter API key</li>
<li>EchoFilter silently analyzes every visitor’s behavior</li>
<li>On form submit, it scores the session (0–100 TrustScore)</li>
<li>Bots get blocked. Real users get through instantly.</li>
</ol>
No CAPTCHAs. No friction. No false positives.
Compatible with:
<ul>
<li>Contact Form 7</li>
<li>WPForms</li>
<li>Gravity Forms</li>
<li>Elementor Forms</li>
<li>Ninja Forms</li>
<li>Any standard HTML form</li>
</ul>
Three protection modes:
<ul>
<li>Block — Bot submissions are rejected with an error message (recommended)</li>
<li>Flag — Bot submissions go through but with a hidden <code>_echofilter_bot=1</code> field</li>
<li>Log — Monitor mode: all submissions allowed, bots logged in your dashboard</li>
</ul>
<h3>External Services</h3>
