Fraud scoring on every submission
A single script on your page watches how a form is actually filled in. Headless browsers, proxy and VPN traffic, hidden honeypot fields, impossible typing speed and straight-line mouse movement all raise the score. Each lead arrives tagged with a fraud level, so you can reject the obvious junk, hold the borderline cases for review, and pass the rest straight through.
Drops into the form you already have
No replatforming and no change to how your forms submit. Add the script, keep your existing flow, and the fraud signals travel with the lead into whatever system you already post to. Consent records and certificate URLs are carried through intact, so the leads you do accept stay defensible.
