Types of Fraud We Prevent

Comprehensive protection against the most common fraud vectors that impact online businesses.

Fake Signups

Bots creating thousands of fake accounts using disposable emails and proxies to abuse trials, promotions, or inflate metrics.

Account Takeover (ATO)

Credential stuffing attacks using stolen passwords from data breaches to hijack existing accounts and commit fraud.

Fake Leads

Low-quality or completely fabricated leads that waste sales team time and skew marketing attribution data.

Affiliate Fraud

Fake clicks, cookie stuffing, and fraudulent referrals that drain affiliate marketing budgets without real conversions.

Coupon Abuse

Multiple accounts created to repeatedly claim promotional codes, referral bonuses, and first-time discounts.

Payment Fraud

Fraudulent transactions using stolen credit cards, chargebacks, and card testing attacks that cost you fees.

How It Works

Combine IP intelligence and email validation in a single API call for comprehensive fraud detection.

IP Reputation Scoring

Analyze IP type (datacenter vs residential), proxy/VPN usage, Tor detection, and historical abuse patterns to generate a risk score.

Email Validation

Detect disposable email providers, check domain age and reputation, validate MX records, and identify temporary inboxes.

Combined Risk Score

Machine learning model weighs all signals together to produce a unified trust score from 0-100 and a clear recommendation.

Behavioral Signals

Identify unusual patterns like rapid account creation, velocity checks, and geographic anomalies that indicate coordinated fraud.
