Fraud Protection in Action
Watch the overview to see how it works, then take a guided tour of the dashboard to see how your team reviews and acts on every risk signal.
Multi-Signal Protection, Zero Friction
Six intelligence signals fused into one risk assessment. Available through the JS client, the server-side API, or both together.
Device Fingerprinting
Browser, device, OS, screen, timezone combined into a stable device identity. Detects automation, headless browsers, emulated environments, and multi-account reuse from the same device.
Behavioral Analytics
Keystroke cadence, mouse movement, scroll patterns, and form interaction timing analyzed in real time. Distinguishes human interaction from automated scripts and click farms.
Email Intelligence
Disposable, role-based, free provider, domain age, MX validity, DNS security posture, and deliverability risk fused into a single email quality signal.
IP & Network Analysis
VPN, proxy, Tor, datacenter, geolocation, ASN, and global blocklists evaluated instantly to surface high-risk connection patterns and geographic anomalies.
Phone Validation
Coming SoonLine type, carrier, VOIP detection, and reachability signal combined to flag disposable, virtual, or high-risk phone numbers across form and API submissions.
Unified Risk Score
200–1000 normalized score with explainable reason codes. Available via synchronous API response or webhook payload. Every signal fused into one actionable assessment.
Webflow reCAPTCHA Isn't Enough
Modern automation and AI agents are built to bypass challenge-based defenses Webflow offers by default.
Bots and automation bypass reCAPTCHA at high rates
Modern automated tools are built specifically for web forms. They mimic human behavior, cycle through residential IPs, and rotate email addresses, all while bypassing Webflow's built-in reCAPTCHA silently.
AI agents have publicly bypassed challenge systems
Advanced AI agents have demonstrated public bypasses of modern challenge systems. Challenge-based tools alone tend to degrade over time.
Your leads are polluted with fake data
Bot-submitted forms contaminate your CRM, waste ad spend, degrade email deliverability, and skew analytics, all while passing existing Webflow protections.
Add Fraud Protection to Webflow in 4 Steps
No developer required. Works on any Webflow plan that supports custom code.
Add the Snippet
Paste the script tag into your Webflow site settings. Navigate to Site Settings → Custom Code → Head Code, and paste it there. No backend changes, no SDK to configure — done in minutes.
<!-- Add inside <head> -->
<script
src="https://cdn.opportify.ai/f/v1.3.5.min.js"
data-opportify-key="YOUR_PUBLIC_KEY"
async>
</script>Protect Your Forms
Create a Form Endpoint in the dashboard and point your Webflow form to the secure submit URL. The snippet handles everything else automatically.
Review by Risk Level
Every submission arrives pre-scored and classified. Your dashboard shows all submissions segmented by risk — no manual triage needed.
Act on the Score
Route clean, low-risk submissions to HubSpot, Salesforce, Slack, Zapier, or any webhook receiver. High-risk and suspicious submissions are blocked or quarantined before they ever reach your CRM.
Built for Webflow Teams
Everything you need to detect and route form abuse without sacrificing user experience or conversion rates
Works with any Webflow form
Native Webflow forms, custom-coded forms, and embedded third-party forms all work with the same snippet.
Zero friction for real visitors
No CAPTCHA. No checkbox. No popup. Legitimate users never know protection is running.
Real-time risk scores
Risk scores (200–1000) are available via API within milliseconds of form interaction, with explainable reason codes.
Device fingerprinting
Track repeated submissions from the same device across different email addresses or form sessions.
Email + IP + phone fusion
Every submitted identifier is scored independently and fused into a single composite risk assessment.
Zapier-compatible
Connect to your Zapier workflow and act on risk scores inside HubSpot, Salesforce, Airtable, or any other app.

Frequently asked questions
How does Fraud Protection work?
Form Fraud Protection: A lightweight JavaScript snippet collects device fingerprints, behavioral signals (typing cadence, scroll patterns, automation detection), and session metadata. This is fused with email, IP, and phone intelligence to produce a risk score (200–1000) with explainable reason codes, delivered via webhook.
Fraud Protection API: Your backend sends submission data to
POST /intel/v1/fraud/analyze and receives a complete risk assessment synchronously: email, IP, phone, content, velocity, and geographic signals in a single response. For maximum signal coverage, deploy both together (hybrid mode) to add behavioral intelligence to API scoring via the opportifyToken.Does it only detect automated submissions?
It also identifies suspicious or manipulated submissions that appear human, including click farms, automated form fills using real user data, repeated low-quality leads, and adversarial traffic designed to exhaust ad budgets or pollute CRMs.
The system focuses on detecting signals of manipulation and risk, not just whether a submission is human.
Is it really invisible to users?
How is it different from CAPTCHA?
What does it detect?
It also detects low-intent or adversarial submissions, including click farms, reused personal data, and activity designed to drain ad budgets or pollute pipelines.
Does it require cookies to work?
Analysis runs on behavioral signals, device and browser characteristics, network data, and submitted information. If cookies are available, they can be used as an additional signal, but the system works fully without them.
Will this impact site performance or page speed?
It does not introduce heavy dependencies and is comparable in size and impact to standard analytics scripts.
How long does integration take?
Fraud Protection API: Generate your API key, send a
POST request to /intel/v1/fraud/analyze with your submission fields, and parse the synchronous JSON response. Most backend integrations are complete in under an hour.How do teams justify the cost?
Invalid or low-quality submissions can trigger unnecessary automations, inflate CRM costs, and reduce the efficiency of paid campaigns. By filtering these before they enter your systems, teams typically see cleaner data, more reliable reporting, and less wasted spend.
