Guided walkthrough + fire test leads at a live dashboard. No signup needed.
Copy your snippet from the dashboard and paste it before </body>. WordPress, Shopify, Webflow, custom sites — anything. No developer needed.
Each submission is checked across email, behaviour, device, IP and AI-context layers in real time, and receives a 0–100 risk score with plain-English reasons.
High-risk submissions are blocked at the form. Real buyers pass straight through — no CAPTCHAs, no friction, no lost conversions.
Syntax, live mailbox (MX) checks, a continuously-updated blocklist of ~100,000 disposable domains, role accounts and gibberish patterns.
LLMs made fake enquiries cheap. Our AI reads the whole lead in context and flags machine-generated messages and fabricated identities.
gmial.com isn't fake — it's a customer you'd have lost. We detect one-keystroke typos of major providers and suggest the fix instead of discarding the lead.
Invisible honeypots, form-fill speed, keyboard & mouse telemetry and headless-browser signatures — bots reveal themselves without annoying humans.
Privacy-conscious, locally-hashed fingerprints catch the same device hammering your forms behind rotating identities. No third-party trackers.
Every verdict shows its reasons in your dashboard. No black box — you can defend every blocked lead to your team or your clients.

We built the scoring to be conservative. Hard blocks need a 70+ risk score (disposable domains, dead mailboxes, honeypot hits). Borderline leads are marked "suspicious" — you choose whether those are blocked or just flagged. And if LeadShield is ever slow or down, your forms submit normally. Fail-open, always.
The script is tiny and loads asynchronously; genuine visitors see nothing — no puzzles, no checkboxes. Validation runs when the form is submitted and typically completes in well under a second, with a hard timeout that lets the form through if we're slow.
Two things changed: bots got browsers, and spammers got LLMs. Old keyword filters miss AI-written enquiries that read like humans. LeadShield combines behavioural evidence (how the form was filled) with AI context analysis (what was written) — both sides of modern fake leads.
14 days, full Professional feature set, no credit card. When it ends, validation pauses until you pick a plan — your data, settings and API key are preserved. No surprise charges, ever.
Yes. Professional's 10,000 monthly validations typically cover 5–10 client sites; Enterprise is unlimited. Many agencies bill "traffic quality assurance" as a line item and send clients the monthly blocked-leads report as proof of value.
Lead data is processed in real time and kept on a rolling retention window (90 days by default, configurable down to zero) before automatic deletion. Fingerprints are hashed in the browser; we don't use third-party tracking CDNs. Details in our privacy policy.
