Why Fraud Protection

Detect Risk at the First Interaction

Invisible intelligence that protects form submissions, lead entries, and contact requests, designed to minimize friction.

Trust at Every Entry Point

Contact forms, lead forms, trial request forms, newsletter subscriptions — every submission is evaluated before it enters your pipeline, across every channel.

Designed to Minimize User Friction

No CAPTCHA puzzles or challenge flows. Designed to minimize friction while still surfacing strong risk signals.

CAPTCHA Alone Isn’t Enough

Challenge-based defenses are increasingly bypassed by automated solving services and modern automation tooling. Fraud Protection scores behavior and multi-signal context so your team can act without relying on puzzles.

Intelligence, Not Gatekeeping

A 200–1000 risk score with reason codes gives your team the context to decide: review, flag, or allow — you stay in control.

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 Soon

Line 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.

Fragmented Protection vs. Unified Trust Layer

Use Cases for Fraud Protection

Detect fraud risk at every entry point, before it costs you.

Lead & Registration Forms

  • Trial abuse prevention: Detect repeated form submissions from the same device or network attempting to exploit free trial and referral offers.

  • Bot registration detection: Identify automated form submissions using device fingerprinting and behavioral signals.

  • Multi-account fraud: Surface linked identities trying to abuse pricing or policies via repeated form entries.

Lead Form Quality

  • CRM pollution prevention: Keep your marketing database clean by blocking fake and low-quality lead submissions.

  • Fake lead filtering: Score and filter submissions from disposable emails, VPNs, and automated form fills.

  • Bot submissions: Detect automated form submissions without adding a CAPTCHA that hurts conversions.

Marketplace Intake Forms

  • Seller & buyer intake: Score marketplace seller and buyer application forms before entries reach your review pipeline.

  • Platform integrity: Protect trust and safety by catching synthetic identities in intake form submissions before they enter your pipeline.

  • Zero friction: Invisible analysis means legitimate users never experience a checkpoint.

Fintech Pre-KYC Screening

  • Reduce KYC costs: Filter obvious fraud signals before paying for identity verification, reducing unnecessary KYC spend on high-risk and synthetic submissions.

  • Synthetic identity detection: Catch fabricated identities and VOIP phone numbers before KYC workflows begin.

Frequently asked questions

How does Fraud Protection work?

Fraud Protection is available through two integration methods: Form Fraud Protection (client-side JS) and the Fraud Protection API (server-to-server).

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?

No. Fraud Protection is not limited to automated submission detection.

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?

Fraud Protection is designed to be invisible to users, typically with no CAPTCHA challenges or puzzles. Analysis happens silently in the background, and submissions are scored by risk level so your team can allow, review, or route based on your configured policy.

How is it different from CAPTCHA?

CAPTCHA asks users to prove they're human, and automated solving and bypass is increasingly common. Fraud Protection analyzes behavioral and signal patterns that are harder to spoof at scale, without a visible challenge flow.

What does it detect?

Bot traffic, fake/disposable emails, VPNs/proxies/Tor exit nodes, device spoofing, abnormal behavioral patterns, synthetic identities, multi-account abuse, and high-risk geographic patterns.

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?

No. Fraud Protection does not depend on cookies.

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?

No. The script is lightweight, async loaded, and designed to minimize rendering impact. It aims to have a low footprint on core web vitals, though we recommend validating in your own performance monitoring after integration.

It does not introduce heavy dependencies and is comparable in size and impact to standard analytics scripts.

How long does integration take?

Form Fraud Protection: Most teams are live in under 30 minutes. Add the JavaScript snippet to your form page, create a Form Endpoint in the dashboard, and point your form to the secure submit URL. No backend changes required. Risk scores are delivered via webhook or visible in the dashboard.

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?

Most teams evaluate Fraud Protection based on the cost of bad data.

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.

What's the pricing?

Fraud Protection uses analysis-based monthly subscription pricing. All signals are bundled into a single analysis with no add-ons. There is no permanent free plan; a 14-day free trial is included. Pricing is shown in your local currency on the pricing page. View current pricing.

Is there a free trial?

Yes. We offer a 14-day free trial with no credit card required. You get full access to all features during the trial.

Is it GDPR compliant?

Yes. We process data as a data processor under your instructions. Behavioral and device data is used solely for fraud scoring, never sold, and retained per our data retention policy. See our Privacy Policy for details.
