EchoFilter

EchoFilter is a form security solution designed to identify and flag fake leads, bots, and spam in online form submissions. It addresses the problem of inflated cost-per-lead and wasted sales team resources caused by automated bot entries and fraudulent sign-ups. The tool analyzes user behavior in real time as forms are filled out, providing an instant TrustScore for each submission. This score helps teams prevent suspicious leads from reaching their customer relationship management (CRM) systems, ensuring that only verified human submissions are processed.

The platform operates invisibly to real users, requiring no CAPTCHA or visible challenges, and adds no friction to the form submission process. EchoFilter uses behavioral analysis, including mouse movement, typing rhythm, and timing patterns, to distinguish between human and bot activity. js, plain HTML, WordPress, and Webflow. For WordPress users, a dedicated plugin allows one-click installation and automatic protection for forms created with plugins like Contact Form 7, WPForms, Gravity Forms, Elementor Forms, and Ninja Forms.

EchoFilter is designed to be fail-open, meaning that if there is any doubt or if its API is unreachable, the form submission is allowed through rather than risking the loss of a real user. The service is GDPR compliant, never storing IP addresses, cookies, or personally identifiable information—only a one-way SHA-256 hash is kept, and no cross-site tracking occurs.

Pricing is usage-based with a free plan offering up to 1,000 lead scores per month, full API access, and a real-time dashboard. Paid plans include the Starter tier with 10,000 lead scores and usage analytics, and the Pro tier with 100,000 lead scores, custom score thresholds, and priority support. There are no seat-based charges, contracts, or setup fees, and users can cancel at any time. EchoFilter is positioned as a form security and anti-bot tool for teams and businesses seeking to improve lead quality and reduce wasted resources.
